Summary

The first thing that comes to my mind when I think about the Xiaomi Mijia 1C is its price. For around $200 you get a great robot vacuum that not only has a strong suction (maybe the strongest in the industry) but also is able to mop, has a pretty much purposeful navigation algorithm and slim body design. Do not expect good mopping results, it is the same most 2-in-1 robots have but still a nice feature to have. If you live in a big house, the 1C might not be suitable for you. But overall it is good for those who suffer from allergies, have pets and live in a rather small and average apartment. For the price of ~$230, the Xiaomi MiJia 1C does not have competitors.

Xiaomi has released its budget 2-in-1 robot vacuum 1C. Additionally, the company presented a cordless vacuum cleaner that has the same name - Xiaomi MiJia 1C. I believe the reason behind the same naming was for users to buy the two machines in addition to each other.

The new robot vacuum has only an 8.1 cm height body, which is the slimmest robot vacuum Xiaomi has ever made. Previously, we have seen Lidar-based models from Xiaomi, the Mi Robot, and Mijia 1S. The new Mijia 1C doesn't have Lidar on the top, so the device is pretty slim and can fit under most furniture where the predecessors can not go.

We already get used to Xiaomi build quality, and this robot vacuum is not an exception, it is well-built and looks minimalist.

As you might notice, the 1C does not have a "tower" on top. There is no LDS laser as well. The robot is equipped with a visual sensor which makes it shorter and cheaper. Unlike other camera-guided robots, the Xiaomi 1C can be tracked in real-time via the app. It has a duo-gyroscope with a visual sensor that work together to create a map of your floor plan.

There are 15 types of sensors sit inside the body to help it navigate and create a map.

More expensive robot vacuum cleaners use lidar that scans your house to build a map. However, the Xiaomi Mijia 1C uses other types of sensors for navigation: dual-gyroscope, TOF sensor (time-of-flight sensor) on the top of the robot, and LED motion tracking sensor underneath. 
All the data received from these sensors is being processed with a powerful 4-core ARM Cortex-A7 processor inside the robot that uses VSLAM algorithms to create a map of your house and build the most efficient path for cleaning.

The robot easily crosses over my medium-pile carpet and door thresholds. It can climb a 2 cm (0.8 in) obstacle.

The Xiaomi Mijia 1C has a 600 ml dustbin, which is relatively big for a robot vacuum.

It has a side brush that along with the main roller brush sweep and collects dust transferring it right into the dustbin. It is also the most powerful Xiaomi robot that can deliver 2,500 Pa of suction. I don't have pets so I have not tested it with pet hair, but considering the strong suction power and large dustbin, this model should be a good choice for pet owners and is enough for the robot to be used on carpets.

The Xiaomi 1C has a washable HEPA filter, so you don't need to replace it as often as non-washable filters. Usually, I wash such a filter once per month. HEPA filtering standards makes this filter suitable for allergy and asthma sufferers.

The 1C has a small and minimalist charging dock. I'm a little bit disappointed tho that the dock doesn't have a place behind it where you can hind the cord and adjust its length but it is not a big deal, just something I used to see in other high-end models.

What mopping can do?

The Xiaomi Mijia 1C is a budget model that can sweep and mop at the same time. To use the mopping feature, you should attach the mopping pad underneath. I noticed that this model uses an improved water tank. Unlike water tanks that I have seen in other similar devices, this one has a small motor inside which works as a water pump, takes the necessary amount of water from the tank and supplies it on the mopping cloth.

The water tank holds up to 200 ml of water. In the box, there is one extra mopping cloth. The mopping function is great for everyday cleaning, but the robot will not be able to handle a stubborn stain, so keep in mind that you need to mop your floors by hand from time to time. Basically, the Xiaomi Mijia 1C drags the mop around leaving hard floor wet but it will not replace manual mopping. Considering the price, this device is equipped with a relatively large water tank so the mopping feature is nice to have, it will definitely reduce the amount of time spent on manual mopping.

For how long the Xiaomi 1C works before recharging?

The manufacturer does not specify for how long the Xiaomi can work tho considering its 2,400mAh battery and 2,500 Pa suction, it should not last too long on the maximum power setting. I tested it on max power mode, and it was able to clean ~40 minutes on one charge. In silent mode it would definitely last at least twice longer, however, I didn't test it yet. I would say this robot vacuum will be a good choice for small houses, or maybe for medium houses with some limitations.

How loud is the Xiaomi 1C?

The Xiaomi 1C is not the quietest device but let's not forget that it has one of the strongest suction in the industry. It produces about 50 dB of noise on low suction settings (silent mode) and around 65 dB on its max settings (turbo mode). Not too loud but you will notice it on turbo mode if it is working in the same room. However, it will not bother you at all in silent mode.

App

Many users ask if they can operate the robot without wi-fi. In short: yes, you can. You can see the map of your house in the app and watch how it cleans your place in real-time. There are buttons in the app to start and stop the robot, also send it to the charging dock. But if you do not use the app, you will not see cleaning history and a created map, also no real-time tracking. You will miss a lot of features but overall the robot is still usable if you do not have a phone.

I got a Chinese version of the robot from Gearbest, and it has a Chinese user guide. Nevertheless, the Mi Home app has an English localization, and I was able to choose an English voice for the robot after updating the firmware.

I've no idea if there will be an international version of this device in the near future, but the Chinese version has one downside: to pair the robot vacuum with the Mi Home app, you will need to choose the China mainland region with the newest update you can choose your region to make it work. It may be not a problem at all if you don't have any other devices connected to the Mi Home app, but in my case, I have an air purifier and other robot vacuums connected with the app in the European region, so they become unavailable when I switched the app region to China.

In the app, you can see when the filter, side brush, and roller brush should be replaced or cleaned.

Also, you can switch between 4 suction power settings, and manually control the robot like a radio car if needed. I do not use the manual mode, but someone might find it useful.

Scheduling is pretty much basic. It does not allow setting the robot to work in a particular room or make it work in a certain zone. You only get a full-home cleaning option where you can set time and suction mode. And that is pretty much it.

Mapping & Navigation

As I said before, the robot is not laser-guided and is not able to create the same high-precise map as laser-based robot vacuums.

I noticed that the Mijia 1C creates quite an accurate layout of your house. The created map is not as accurate as created by the Lidar-based robot vacuum, but still, you can recognize all your rooms and house layout. One of the things I wish the robot had, is the ability to track its cleaning path as some Lidar-guided robots offer. Not a big deal, you still see where the robot cleans but it is not as detailed as I have seen in the robot vacuums with Lidar.

Another downside is that you can track it in real-time but nothing more. No zoned cleaning, no-go zones, nor room cleaning. Still better than randomly-moving robots or robot vacuums with gyroscope mapping. Also, there is no option to save the created map, so it will be erased and rebuilt from scratch next time you start the robot.

There is a chance that Xiaomi will release a firmware update with no-go zones and zoned cleaning in the future, but we don't know it for sure.

Cleaning

When you get a ~$200 robot you do not expect it to be very good at cleaning and I was also skeptical at first. I thought the robot was going to be loud and not as good at cleaning carpets as other models I previously tested. This is when I am glad to be wrong.

The 1C is not as loud as the Roborock S5 and overall is not as loud as you might think it is. I tried to run it on Max mode and also on Silent mode and it wasn't too noticeable on both.

The Xiaomi Mijia 1C does not have carpet boost so if you have carpets, I would suggest to run it on high suction settings for the best performance. According to Xiaomi, the 1C has 2,500 Pa of suction power, which is the highest number I've seen so far. Most of the flagship robot vacuums available on the market today, have approximately 2,000 Pa of suction. Even though we can't verify if these numbers are correct, this robot vacuum cleans my middle-pile carpet very well, especially considering the price of the device.

Because of 20 mm (0.8 in) climbing ability, the 1C is suitable for thicker carpets while its predecessor, the Xiaomi Mi Robot, can only climb onto a 15 mm (0.6 in) carpet.

Based on my personal experience the MiJia 1C lasts up to 113 minutes on low power settings and 40 minutes in high mode making it suitable for average homes.

One thing I don't like is the roller cleaning brush. It is the same the Roborock S5 uses, fewer bristles than the one inside the Roborock S6 and also does not have detachable side tips which makes it harder to clean from tangled hair.

If you have long hair, be prepared to spend some time to remove the hair of the edges and this is why I love the latest Roborock S6 and S5 Max vacuums that much. Not too bad though but you should know about it. After running it the first time, even though the floors were cleaned a day before, the Mijia 1C got some hair tangled around the brush and I had to use a special cleaning tool that comes in the box to remove that hair.

Overall the cleaning performance is great for the price. The robot is good on carpet, it removes debris and hair, suitable for pet owners but has a short battery life, which is expected to the suction it has and a relatively small battery.


Price & Where to buy

Xiaomi MiJia 1C so far is only available on Gearbest at ~$230.

To buy or not to buy?

The first thing that comes to my mind when I think about the Xiaomi Mijia 1C is its price. For around $200 you get a great robot vacuum that not only has a strong suction (maybe the strongest in the industry) but also is able to mop, has a pretty much purposeful navigation algorithm and slim body design.

Do not expect good mopping results, it is the same most 2-in-1 robots have but still a nice feature to have.

The main disadvantage for me is that I needed to change the region to China in the app settings to make it work. This is not a problem anymore, the app received an update and now I can choose any region and connect the robot without any problems.

If you live in a big house, the 1C might not be suitable for you. But overall it is good for those who suffer from allergies, have pets and live in a rather small and average apartment. For the price of ~$230, the Xiaomi MiJia 1C does not have competitors.

    This robot works in the europe region. Small battery is bad.

      Thanks for your comment. I just checked the Mi Home app and now it is available in the European region. We were not able to find it when reviewed the robot but looks like Xiaomi added it to other regions recently.

      Agree about the battery. For those who live in a small apartment, it should be enough, but for bigger houses, it is not suitable at all.

      Hi, in the article where you compare different Xiaomi robots, it says this model can only sweep or mop at a time.
      but in this article, you say it can do both at the same time.
      Could you please confirm which one is true? Thanks.

        Hi, Dean

        Thank you for noticing, I have fixed the Xiaomi comparison. Yes, you are right, there was not much info about the 1C before the chart was done so I thought it has two separate containers that cannot be together at one cleaning cycle, but I was wrong. The Xiaomi 1C can do sweeping and mopping at the same time.

        Hi, could you please update table with real runtimes? I guess the 40mins is for highest power and for other vacs runtimes are for lowest. It eems to support RECHARGE & RESUME and filter seems to be washable one (according to gearbest description). Thank you!

          I will test it today. On high power settings, the Xiaomi 1C works for 40 minutes, going to run it on low power and tell you the results. You are right, the MiJia 1C resumes cleaning after recharging and the filter is washable too. I have changed the specifications.
          Thanks :)

            So after running the Xiaomi MiJia 1C on low power, I figured it can do up to 113 minutes on one charge but it does not have enough suction to provide deep cleaning on carpet and would be more suitable for low-pile carpets and hard floors since it does not have carpet identification to boost suction on carpets (relate to low power settings).

              Hello,
              The Xiaomi Mijia 1C seems to be very interesting with the features it can offer for this low price. Nevertheless, it has a low battery capacity. We leave in a house of 2 floors of approximately 60sqm each, I am afraid the battery won't be enough. But if it has a function Recharge & Resume, therefore the low battery capacity should not be a blocking point for bigger surfaces, should it?
              Also, I understand that the vacuum can't keep the map in memory. So how this Recharge & Resume can work then?
              Or do you think that for us the Roborock 5S would be more suitable?
              Thanks in advance for your help and advice.

                Hi, Sébastien
                I would not recommend the Xiaomi 1C for a big multi-story house. Firstly, it does not have enough battery life and secondly, it will not be as efficient in a big house.
                Recharging takes time, you will have to wait forever until the robot finishes cleaning the whole house. It does not save a map, it disappears once the robot finishes cleaning until it does not, you can see the map on your phone.
                For a big house with more than one level I would suggest getting a laser or camera guided robot, the Roborock S5 sounds just fine in your case but it does not save more than one map either. You will have to move the robot manually upstairs/downstairs anyway every time so it can generate a new map.
                Other than that, the S5 would be more suitable for your home than the Xiaomi 1C.

            How does it compare to Xaiowa E2? Is its navigation any better? Does it cleanup the room faster?

              Hi there, I've never used the Roborock Xiaowa E2, so hard to say for sure. As a brand, I would prefer Roborock over Xiaomi. Even though they are partners and Xiaomi is a major investor of Roborock, I like the Roborock customer service more. Also, I think Roborock is better in terms of further app and firmware updates. Regarding the features and specifications, the Roborock Xiaowa has longer battery life, carpet boost, roller brush with detachable side tips (much easier to remove tangled hair). The Xiaomi 1C uses a gyroscope and accelerometer for navigation (as well as the Xiaowa), but in addition, has a TOF sensor on the top. Not sure if it has more efficient navigation though. According to specifications, the Xiaomi has a stronger suction of 2,500 Pa, but I don't know if we can trust these numbers.

                Thank you for testing runtime on silent mode! It seems to be ~10mins/10% longer than E2. I guess that's because 1C runs battery down to 15% and E2 to 30%.

                BTW. how to detach side tips of roller brush on E2?

                  Oh, I am sorry, during online research I realized, the Xiaowa E2 has the same old-style brushroll the Roborock S5 has, which means it does not have detachable side tips so they are identical with the Xiaomi 1C. Sorry for misleading you.

                  I assume the Xiaowa has more suction on low power than the Xiaomi does and in addition, the E2 has carpet boost which is more helpful on carpets tho do not save battery. I would say in terms of battery life efficiency, the Roborock is better.

                      I haven't tested the robot in standard mode, I did so with low and high power settings and figured it can last up to about 40 and 113 minutes respectively.

                  I haven't tested it myself and do not plan to get one. I might have a text comparison with the two though. They are equally similar, the Xiaowa tho has carpet boost but if you have many medium-pile carpets and/or a pet, I would recommend getting the Xiaomi. On low-pile, you won't see the difference between the two.
