Xiaomi Mijia STYJ02YM LDS Edition Review

By Natalie Red·Updated: Nov 6, 2019· 5 min read

In August 2019, Xiaomi released the newest robot vacuum - Xiaomi Mijia STYJ02YM. It is the first model in the family that can do both: mopping and sweeping.

With increased suction power, more efficient cleaning path in mopping mode, additional features a bigger accessory pack, the newest Xiaomi MiJia STYJ02YM might be a best-seller soon. Let's see what makes the new model attractive and why it's worth buying.

Design & Navigation

The Xiaomi Mijia STYJ02YM has the same design as its older brother, the Xiaomi Mi Robot.

With the LDS laser on top, the robot scans the surroundings to create a map of the cleaning area so the robot knows where it should clean. Mapping helps the vacuum to cover the whole area without having it cleaning the same areas twice or leave some areas untouched.

The Xiaomi Mijia STYJ02YM is guided by the LDS laser

When the vacuum is working, it follows a back-and-forth navigation pattern.

The cleaner is equipped with 12 high-precious sensors that help it navigate around without falling off, bumping into furniture, or just be more careful when operating.

When it finishes cleaning, it creates a map which can be divided, merged, and has the ability to name each room. This feature is very helpful if you don't need to clean the whole house. Just set the robot to go directly to the kitchen/bedroom and let it work.

The most significant improvement over the previous models - mopping feature. The Xiaomi Mijia STYJ02YM can mop, sweep, mop and sweep at the same time. Neither the Xiaomi Mi Robot or Xiaomi MiJia 1S Robot Vacuum can mop.

The Xiaomi Mijia STYJ02YM package includes many extra accessories
The package contents

Mopping mode

The Xiaomi is equipped with two containers, the one (550 ml) for sweeping (dust container), the other container (550 ml) is 2-in-1 for mopping and sweeping. The second container can be used if you want the robot to mop and sweep. The previous models have a 420 ml dust container, by the way.

the Xiaomi Mijia STYJ02YM is equipped with two containers, one of is 2-in-1 and has two types of mopping pads for different cleaning needs

If you need the Xiaomi to mop only, the 550 ml water container can be bought separately.

We are not sure if you can make the robot only mop with the included container, though it can do both at a time.

The Xiaomi Mijia STYJ02YM can sweep, mop or sweep and mop at the same time

The two in one container can be half-filled with water for mopping, the second half of the tank is for dust the robot sucks up when working.

In mopping mode, the Xiaomi follows a Y-shape (two-way repeated wiping) path. It helps to provide better mopping performance since the robot doesn't just drag the mop but returns to the same spot twice for better results.

There is not much information about the model. The manufacturer says it has three level water settings, which means you can set the level of water dripping depending on your needs. Unfortunately, we are not sure, either you can change the settings in the app or directly on the water tank.

There are two types of mopping pads in the box included: wet mop and a half wet mop. Insert the 2-in-1 water container, attach the mop stand with a pad you need and let the robot work.

We should say, the Xiaomi Mijia STYJ02YM is not suitable to remove stubborn stains, but it is a better solution than most hybrid models that just drag the pad. The robot is suitable for everyday mopping and will prolong the time between actual manual mopping sessions.

Mi Home & Smart Features

The Mi Home app has many options such as tracking the robot in real-time, manually control its movements, switch between cleaning modes, track when the accessories need to be replaced, etc.

The smartest features would be zoned cleaning, restricted areas, and room cleaning.

If you want the robot to not go to certain places, you can set blocked zones, and the robot won't cross them. Useful if you need to prevent carpets from getting wet when the robot is mopping, or some areas might be cluttered, etc.

Setting virtual walls and a restricted area in the Xiaomi Mijia STYJ02YM

Zoned cleaning is great for spot cleaning. If you have high-traffic areas or places that are dirtier than others, you can make the robot work there by drawing a rectangle on the created map.

Make the Xiaomi work directly in the kitchen by using the room cleaning feature

Room cleaning is our favorite feature. Since you can divide the map into separated rooms, the robot can be ordered to go to the kitchen or living room if needed. If you don't need to clean some rooms such as a guest room, you can either use blocked areas or simply choose other rooms to clean.

Battery life

The Xiaomi Mijia STYJ02YM has a smaller battery size of 3,200 mAh than its brothers Mi Robot and MiJia 1S which have 5,200 mAh.

The robot is ideal for big homes

Predictable, the newest MiJia lasts less, up to 110 minutes other than 150 minutes the siblings do.

Since the Xiaomi resumes cleaning in case it does not finish the job before the battery dies, the robot is suitable for big homes. When the battery runs lower than 20%, it returns to the dock, recharges up to 80% and finishes cleaning from the same spot it left off.

Suction Power

The newest model has the strongest suction among the Xiaomi cleaners delivering 2,100 Pa of suction. The older models have 1,800 (Mi Robot) and 2,000 Pa (MiJia 1S).

Stronger suction helps a lot when you need deeper cleaning on carpet.

Climbing Ability

Crossing ability seems to be increased too. From 0.59 / 15 mm (Mi Robot) to 0.79 in / 20 mm (Mijia STYJ02YM).

It matters if you have taller thresholds or thicker carpets. The Mi Robot has issues with thick carpets, the newest model promised to be better at this.

Filtration System

Since there's not much information, we are not sure if the robot is equipped with a filter that can be washed with water. However, we know that the Xiaomi Mijia STYJ02YM is equipped with a HEPA filter and is safe for everyone who suffers from an allergy or asthma.

Price & Where to buy

The Xiaomi Mijia STYJ02YM so far is only available on Gearbest where you can get it for ~$530.

    This is the exact same model as Viomi V2 just rebadged as Mijia

      The Viomi V2 has a different color option, it is a black&mint and its accessories are made in the same color scheme. The Xiaomi is black/white&orange.
      The Viomi has a filter that can be washed with water, the MiJia's filter is non-washable.
      The Xiaomi stores up to three maps in memory, the Viomi saves one map only. (not completely sure about this but the previous MiJia version is capable of saving multiple maps, so I assumed the new one is too).
      The Xiaomi is equipped with a two-in-one water tank in the box, and you can get a water tank separately, the Viomi has two containers: one is for dust, and the other one is for water. The two-in-one container also can be bought separately.
      The Viomi's crossing ability is 20 mm (0.8 in) while the Xiaomi can do a 15 mm (0.6 in) obstacle. This makes the Viomi suitable for thicker carpets.
      The Viomi's dust container holds 600 ml of debris, the MiJia's dustbin is 550 ml.

      As you can see, they might have similar features, but in fact, 90% of the existed robot vacuums do, it does not make them the same. Each robot has advantages, and the Viomi vs. MiJia is no exception.

        How do you get the Xiaomi to store more maps?
        Can I just take it up to my second floor and use it there and it will remember the ground floor and second floor map separately?

          The robot creates a map when it starts from the charging dock and automatically gets back to the dock when finishing cleaning. If you place the dock on the first floor, the Xiaomi cleans and returns to the dock on its own, it will create one map. For the second floor map, place the dock manually upstairs, let the robot starts cleaning from it and finish cleaning by docking itself. Now you have two separates map and the robot will recognize its location when you place it upstairs or downstairs.

            Curiously, there are two other robot vacuums: Proscenic M7 and Conga 3690 Absolute. They look absolutely the same as the Viomi V2. Would be great to know who is the original OEM manufacturer of these products.

              Yes, the structure and many spare parts, even if Cecotec declares… 2700Pa. The software and the mapping are different. I had Conga for a few days. It has 5 maps and all the possible functions, even the engine or water stop. The problem is the connection and the bad assistance.

            Hi, I'm looking for buying one of these 3 models for next «11.11» sales: Xiaomi Mijia STYJ02YM, Viomi V2 PRO or Roborock S50.
            Have a dog, live in a flat with 2 floors.
            Which one is better? The «old» Roborock or the new 2 brothers Viomi and Mijia?
            Will roborock continue to have new firmware releases in future (maybe multi floor maps)? Or is it better choosing a new model with new features even if maybe the app needs to improve?
            Thank you

              Well, let's see. Please keep in mind, any of the Xiaomi or Viomi is not related to Roborock. Roborock is a separate company and has nothing in common with the Xiaomi or Viomi except for the Xiaomi Mi Robot which they produced with Xiaomi together. Why I am pointing this out? Roborock has great customer service and if you have any issues with the product, you can always contact them and get a response in no time which you can't do with the Viomi or Xiaomi.

              The Roborock app (or the Mi Home app) gets regular updates which I can't say for sure the Viomi or Xiaomi will have. For example, we have the Viomi V2 and the app is still raw even though the product was released about 6 months ago.

              As for the multi-floor maps update for the Roborock S5, I don't know for sure whether the vacuum will have it or not.
              Do you have carpets? If you don't have thick carpets or tall thresholds, have a look at the Roborock S4. It has smart features of the S6, only can't cross any obstacle taller than 15 mm and lacks mopping. Also, if you live in a flat with 2 floors, I would recommend getting a robot with multi-floor map support but it's not necessary, just would be more convenient to use in such a household.

              Also, if your dog sheds a lot and has long hair, consider getting a robot with a brush that has detachable tips, much easier to maintain, the Viomi's brush and the Roborock S5 brush is solid, not sure about the MiJia's roller.

              Hope that helps. If you have any questions, feel free to contact me.

                Hi Natalie,
                Thank you very much for your answer. Now I' m more confused...Roborock was my third choice.
                I have read that PRo version of Viomi V2 has a new and fixed app that solves all previous problems.
                Regarding the brush, my dog has short hair but in my family we have long hair, so maybe roborock Is better. Also for price It Is cheaper.
                But mopping Is surely worse and I'd prefer have a good mop and both Viomi and mijia mop with Y way, ahead and back.
                So, It Is a really difficult choice.

                  You can read a comment from Jamerica Merit under this video where she complains about the app of the Viomi V2. Honestly, I don't think they solve the previous problems on the Pro version. I am still very skeptical about the Viomi. When it first was released I recommended it since it seemed to have nice features, but it turned out to have many bugs too so who knows who knows…

                  The Roborock S5 has a solid brush too, the S4 and S6 are equipped with a brush with detachable tips.

                  I see what you mean about mopping. Go with the Xiaomi, it has the same pattern which is really great, it does work better at removing stains and overall my floors looked shiny after the Viomi had done its job. At least Xiaomi is a known brand and this is their fourth robot in the model line so I hope they all have better firmware.

              Unfortunately, there are no reviews of the new Xiaomi so I can't say for sure but the previous model (Xiaomi MiJia 1S) supports multi mapping so I figure, the new one save a few maps as well.

                    do you want an example? the dustbin is identical, it only changes color. it is not true that they are not news, but the product must have it to write a review, so you will know that it has only one map, and more. Many accessories can be exchanged between Viomi and Mijia Sty. The mapping has become very similar and it is not true that there have been no updates for months, as is stated in the answers.

                      I especially criticize the responses to comments. The article should be updated, as this product is now becoming popular! Did you know that Xiaomi had commissioned Viomi to build a new Robot? Just read.
                      A tip: if you have STYJ02 you can make an exact, updated review, since from August the product has already received 2 new firmware, Viomi V2 and V2 Pro, just 1. People must be properly informed.

                          Yes, and some online stores explain it. I used the mixed can of Mija on Viomi recognized her; I installed the 550ml tank of Viomi on Mijia and the robot is set automatically in Mop mode. There are some differences, but they mainly concern graphics and programming: Viomi does not choose the area to be cleaned, Mijia yes; Viomi has a more limited main menu, more complete Mijia, for example you can check suction power and quantity of water on the same screen. Viomi speaks English, Mijia only Chinese for now. But the structure is practically identical.

                          As I mentioned in the comment section earlier, these are different companies even though Xiaomi is related to the Viomi's robots, customer support, firmware and software is different. This may cause issues with updates and customer help if you need to get one.

                          As for the product itself, they are very similar yet a bit different anyway:

                          1. No multifloor map support. The Xiaomi stores one map only while the Viomi stores up to three maps. Useful for those who live in a multi-floor house or want to save a few maps with different no-go zones, for example, to keep the robot of carpets in mopping mode.
                          2. Not washable filter in the Xiaomi. I am not sure about this one, I only know the Viomi's filter can be washed with water, I have not tested the Xiaomi myself so I don't know about the type of filter inside. A washable filter meant to last longer.
                          3. Two vs. three containers in the box. The Viomi comes with three containers in the package: water tank, dustbox and 2-in-1 container for water and dust if you want it to vacuum and mop at once. The Xiaomi has two containers in the box: dustbox and 2-in-1 container. If you have a big area to mop, you'll need to refill the Xiaomi's container a few times during mopping.
                          4. Accessories. The Xiaomi spare accessories are widely sold, so far I don't know where you can find additional tools to the Viomi V2/V2 Pro.

                          It might be a bit confusing for many people to see the difference between the two which is understandable. Anyway, hope that helps you to understand the difference between the two.

                          Feel free to comment if you have questions :)

                            Do both robot vaccum cleaners use the same accessories?
                            All accessories they look the same (filter,watertank, dustbox, 2-in-1 container), exept from the brush and the roller have different colour.

                              In my opinion the most important thing is to explain the difference between Viomi V2 and Viomi V2 Pro. Can you show me images of the menu to eliminate any doubt on the multi map?

                                  You mean multi-map of the Viomi V2 Pro? I've seen it on Gearbest, it says the Viomi Pro supports multi-floor management on the screenshot. And also, the geekmaxi website claims the same: «Additionally, it can store several floors map to improve cleaning efficiency.» Now I am not sure about the multimap support. Does it or does not store more than one map?

                                  The Internet is full of sites selling accessories for Viomi…

                                    The accessories for Xiaomi are cheaper from Viomi. So, if Viomi's robot vacuumm cleaners use the same accessories, you can use Xiaomi's accessories.

                                    Natalie, let me correct you. The Xiaomi STYJ02YM does have multi map support. I have the unit and it allows me to define rooms. The funny thing is both the V2 and STYJ02YM both use the same device profiles

                                      Hello, John.
                                      Does it have multi-floor or it allows define rooms? These are two different features. I do know you can separate rooms with the Xiaomi, but I still have no proofs of it supporting multi-floor so I am kind of confused here.

                                  to conclude my comments I want to show you the real time to install the mop on Mijia and Viomi. In some videos it seems more difficult… but it's faster than Roborock.

                                    Hola a todos. Tengo en mi casa el viomi v2. No el v2 pro. Pregunta. Si compro el tanque 2 en 1 mi robot aspirara y fregara al mismo tiempo?
                                    Pregunta 2: el xiaomi v2 es igual al viomi v2 pro?
                                    Por los comentarios anteriores se deduce que utilizan los mismos tanques y salvo el sofware y la marca parecen identicos.

                                      Any chance Alfawise V10 Max is another Viomi V2 or Mijia?

                                      Alfawise had released LDS based V9s just few months and they already have a new entrant now.

                                      Alfawise V10 Max is for pre-sale on gearbest for $260 with coupon $220.

                                      Any reviews or views on this?

                                        The V10 Max looks similar to the Viomi/MiJia but I have had a bad experience with Alfawise customer support before so I don't want to recommend their products.

                                          Came across this thread while I was searching for Alfawise V10 Max, most other posts on the web (very less results as its a new vacuum) currently are for coupons or so called reviews + coupons (I doubt they have even seen this device, mostly they are read outs of the spec and sharing the GB coupon).

                                          I would be buying this (had shortlisted 360 S7 and Alfawise V10 Max, both new, mostly likely will get V10 due to budget) during GB thanksgiving sales, will share my views/reviews on this device (how it performs) and share if they have all features supported which they claim here www.gearbest.com/robot-vacuum/pp_009195968752.html Also if their customer support is good + GB helps sorting out any issues with devices, as GB is exclusive store for Alfawise.

                                            When I had an Alfawise upright vacuum, its battery stopped working after a few weeks (10 cleaning jobs max).

                                            Nothing against Alfawise just saying…

                                              Woah! this is bad.

                                              As a reviewer may be nothing against Alfawise, but ya would not be able to recommend their products to anyone. As a consumer, that is ~$260-$280 down the drain. It is surprising Gearbest being the exclusive seller of Alfawise products either of them did NOT give a damn. This experience of yours is making me re-think.

                                              Thanks!

                                                Finally found the OEM for Alfawise V10 Max. The manufacturers name is «DONGGUAN ZHIKE INTELLIGENT SCIENCE AND TECHNOLOGY CO.,LTD» and their website — www.yhrobot.com/en/

                                                OEM model is called as ZK901 as I mentioned it earlier, and Alfawise is renaming it as V10 Max, however there are some retail brands who are keeping ZK-901 as is, like Liectroux ZK-901 and more.

                                                www.yhrobot.com/en/Item/list.asp?id=1729

                                                This might be one of the cheapest Laser based Robot vacuums. I did not buy Alfamax V10 Max (and instead bought ABIR X6 during BF sales, hope it was not a bad decision, yet to receive the product) as I did not want to buy Alfawise from GB after reading Natalie's experience, will revisit this during 2020 11.11/BF sales, by that time we will have enough reviews of this model as well.

                                                  Would love to hear your experience of this model, how well it performs, etc. Especially I would love to know about its mapping capabilities.

                                                    Sure, I should receive ABIR X6 between Wednesday and Saturday, will share my experience with X6.

                                                    During BF sales there were 3 Robo Vacs that I had shortlisted which were < $200 (Between $170 — $190). Neatsvor X500, Liectroux C30B and ABIR X6 (and Alfawise V10 Max, but dropped it even though it was my first preference). Of the 3 ABIR X6 had additional functionality of virtual lines (Max 4) and Clean Zone (where we can select zone to be cleaned), that is why ended up going with ABIR X6 (not because of camera, I doubt camera does anything ;-p). Also, from my searches and looks of X6, I felt its nothing but Trifo IronPie M6+ (from same OEM and customized to look different and features/firmware probably)

                                                    I found this video interesting as well — www.youtube.com/watch?v=DmD1CAkYMwg Probably ABIR/OEM teams testing video.

                                        After a bit of search finally found the OEM. The OEM model is called as ZK-901. If you search for ZK-901 you will see the model is 2 in 1 vacuum cleaner with 'Y' type mopping :) such as this — www.ect.my/evatronic/evatronic-zk-901-robot-vacuum-with-water-tank-laser-scanning and many more. Orig app in android is called as «Laser guided robot vacuum cleaner» by DGZK.

                                          I highly doubt that this is the OEM manufacturer. They have a creepy photoshopped brand name on the photos. In the product description, photos of three different robot vacuums from other brands. It looks more like a scam.

                                            I agree with Michael Fisher, I doubt Viomi V2/Xiaomi Mijia STYJ02YM is from same OEM, though features seem very similar.

                                            However, from my searches (which were concentrated on Alfawise V10, after seeing this thread) I feel V10 could be re-branded ZK-901 from the pictures of the device and app snapshots (from GB sale page). But, it could very well be totally different (as from previous experience what we see in sales pictures + features they claim would differ a lot from realty).

                                            Hello.

                                            Could anyone who own a STYJ02YM could confirm that the water-tank from viomi v2 / viomi v2 pro fits to the xiaomi model?
                                            I'm willing to buy that kind of tank but I can not find any dedicated water tank for the xiaomi model.

La única pega es el idioma sólo chino. Una pena que internacionalicen un producto y no pongan varios idiomas en el software o actualización. Alguien sabe como solucionarlo. Gracias

                                                      I'm coming from the 1st gen Xiaomi/Roborock vacuum which I got when it first came out, so that's where the bar as been set with regards my expectations.

                                                      Pros:
                                                      Suction is great and does a very good job of cleaning on both tiles and carpet — although, so did the 1st gen but without as good of a suction rating.
                                                      Mopping is surprisingly good and, with a bit of floor detergent in the tank, leaves my tiles clean and shiny.

                                                      Cons:
                                                      Pathing is ok but it's ability to detect obstacles is very questionable as it bumps into a lot of things the 1st gen didn't (ie. doesn't see/register an obstacle and bumps it constantly or gets stuck).

                                                      Details:
                                                      I've a pedestal fan where is base is low to the ground and the vacuum doesn't appear to be able to see it so it bumps into it constantly, moving the fan around the floor. In one case, the vacuum pushed a fan over toward a table and, as the fan was set to osscilate, it swept an ornament off a table and smashed it on the floor.

                                                      It also struggles with my kitchen chairs, which the 1st gen didn't. It's narrow enough to squeeze through the legs and some days it does and some days it manages to get wedged.

                                                      Raised surfaces is also a bit of an issue for me.
                                                      They've raised the vacuum up a little since the original model which means it can't get under the things that the original one could, which is a nightmare for me as my couch is now a problem whereas it wasn't before.
                                                      They've also given it some form of make-shift suspension which I imagine they thought would allow it go up or under certain things.

                                                      But, I believe there's a bit of a design flaw — maybe poor wheel placement (the closer the wheels are to the centre of the vacuum, the worse this effect is) because when it drives up onto my rug, the front tilts upwards to drive up onto it but that causes the rear to tilt downwards and touch off the floor in a dragging motion, so the vacuum sometimes gets stuck trying to do a wheelie! :) Again, didn't happen to the original gen model.

                                                      It does the reverse of this in another one of my rooms where it doesn't look like it can detect my black glass tv cabinet which is low to the ground.
                                                      It's almost low enough to go under it, so it drives into the unit and manages to get the front of the vacuum in under the TV unit and the front dips down and the back sticks up in the air and it forcefully wedges itself under it until it shuts off and I have to pry it out when it gets stuck.
                                                      May be just an inability to detect black glass as it might be reflective or something — so this may be unavoidable.

                                                      One other minor design flaw is with the water tank/dustbin.
                                                      When you fill it with water and close over the lid, you would think prevent any water getting out.
                                                      But, there are 2 dripper holes under the tank which allow it to drip water onto the mop when it's fitted.
                                                      These both drip water constantly unless you flip the tank upside down up until the point you insert the tank into the vacuum — I noticed this after finding a trail of dripped water from my kitchen sink to the vacuum the first time around!
                                                      Bit awkward but easily enough worked around.

                                                      APP:

                                                      Pros:
                                                      Has lots and lots of potential and some nice features, although the 1st gen has the majority of these same features nowadays with the updated firmware and app.
                                                      The «restricted areas» is a good idea and may be very useful to some people that want to section off an area in a room to avoid.
                                                      Has the ability to manipulate the map so you can name particular rooms and divide/merge rooms and set virtual walls etc.

                                                      Cons:
                                                      If you want the whole house mapped out, you need to let it do a full, continuous, run at least once across the whole house.

                                                      Randomly drops off of the wifi and becomes unreachable via the app at least 1-2 times per month.

                                                      Details:
                                                      The app looks like you can select a particular room and hit a specific option for it to turn out and drive out to the selected room and clean that room.
                                                      Unfortunately, in practice, this just turns on the vacuum and it cleans the whole house as normal.

                                                      There is a lot of messing about with maps.
                                                      If you turn on the vacuum and let it clean your house, but it notices any differences or something has moved, it will prompt you to either update your map or replace it — this is very annoying.
                                                      If it bumps into a child or dog's toy on the ground, or you move a chair a little bit, it will consider this a change and prompt you about the map as above.

                                                      I had almost my entire house mapped and one day I wanted to clean only the living area so all the other rooms were closed. When it finished cleaning the living area and returned to the dock, it asked me to update or create a new map — I tried update and it ended up updating my full map with just the living room…

                                                      I'd much prefer a cancel or «do nothing» option to just maintain the existing map and forget whatever it's trying to update.

                                                      Getting my entire house mapped was a pain.
                                                      If you do a full clean of your house and have one bedroom door closed, you have no way of adding that room into the map later on and you will need to redo a full clean of the house and let it go in and map that bedroom.
                                                      In my case, I wanted to add 1 room I missed so I let my vacuum start and it worked it's way into the new room early on in the clean and finished it — I stopped the vacuum and hoped this would just update the existing map with the new room added — it didn't. It just created a new map with the areas it cleaned up until the time I turned it off.
                                                      I've lost patience with this so I reverted to a previous map which had everything bar 1 room mapped and I carry it into the unmapped room each time and go through the annoying map update prompt the next time I open the app.

                                                      For me, when it comes to mopping, it's a bit time consuming as I have to open up the app, go into the options and select the restricted area option, draw a square around the rug to restrict it so it doesn't mop it and then set the vacuum to clean — that takes about 5 minutes including filling the tank and attaching the mop which is a bit of a nuisance.

                                                      Then, when I want to just vacuum, I have to do the above in reverse and remove the restricted area or it won't vacuum my rug.
                                                      If I could have 2 maps — one for mopping and one for vacuuming — that would be ideal.
                                                      There are some smarts in both the mop and the water tank attachments, so it already has the ability to detect when either are attached.
                                                      If it could automatically select your «mop map» once you've attached those, and select your «vacuum map» when they're removed, that would be an amazing quality of life improvement and I can't imagine would be very difficult to do.

                                                      Hoping in the future there will be some software improvements to the app and firmware updates for the vacuum's mapping that resolve some of the above issues as I genuinely like it and it has a lot of potential, but I think it's been let down by quite a few oversights.

                                                      There is also little or no information available online with regards a changelog/release notes for the current app/firmware and no indication of anything upcoming in the future.

                                                      In closing, if you had another variation of robot vacuum, I probably wouldn't recommend this vacuum today as it doesn't feel like the finished article yet.
                                                      I think it's too early in the firmware/software lifecycle and I would hope it will improve over time, like the 1st gen did.

                                                        Hello, I find your description very interesting. I am worried about what you have said that the water tank loses water. You could explain a little better so that I can understand you.
                                                        Thank you.

                                                          The water tank has 3 holes… 1 at the top, with a rubber stopper, and 2 at the bottom that just constantly drip water — this is designed to drip water on the mop to keep it wet when it's mopping.

                                                          The issue is when you fill the tank at your sink, you have to walk to your vacuum and insert it which is where I get lots of droplets of water on the floor.

                                                          My workaround, turn the tank upside down as you move from sink to vacuum because the rubber stopper prevents water coming out of the top.

                                                        Hi! Is it possible to replace the battery (3200mah) by 5200mah battery?

                                                          Hi there, unfortunately, I don't know if you can do so.
