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.
With the new update, you can control the water dripping level for different mopping tasks.
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 did get to test that. On low power, the Xiaomi MiJia 1C lasts up to 113 minutes on one charge.
I would say this robot vacuum will be a good choice for small houses, or maybe for medium houses with some limitations.
The Xiaomi MiJia 1C has resumption which means when the cleaner still needs some work to be done, the robot docks itself, recharges, and gets back to resume cleaning from the spot it left off.
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.
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.
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 running 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. If your home is bigger, the Xiaomi will return to the dock, recharges itself and then resumes cleaning after charging the battery up.
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 make it harder to clean from tangled hair.
If you have long hair, be prepared to spend some time removing 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 for ~$230. Use the coupon code GB-APMJ1C and buy it for $209.99.
To buy or not to buy?

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.
