The Xiaomi Mi Robot Vacuum Mop P and Xiaomi Mijia 1C are the most popular Xiaomi robot vacuums. I already compared all the Xiaomi robot vacuum cleaners, but a lot of our readers asked about the differences between the Mijia 1C and the Mop P, so here is a detailed comparison between these devices.
Mop P and Mijia 1C detailed video comparison
Things the Xiaomi Mi Robot Vacuum Mop P and MiJia 1C share
- Follow the same back and forth purposeful navigation pattern which helps the robot to not miss a spot as it cleans compared to those robots that randomly bounce around.
- A HEPA filter and are safe for those who are dust-sensitive.
- About the same runtime and resuming cleaning if the robot didn't finish the job on the first run.
- As to smart features, the 1C and Mop P both allow setting restricted boundaries and zoned cleaning.
- Saving a map after the cleaning which helps the robot to understand where to clean the next time and be more efficient.
- Decent mopping feature. It does the job, the Mop P does it a bit better but both are better than an average robot vacuum at mopping.
In terms of cleaning, the Xiaomi Mijia 1C does a better job on carpet and hard floors while the Mop P is slightly better at mopping. It is also more efficient because of the Lidar and has numerous smart features as it can go clean the kitchen directly etc.

The difference between the two
Let’s talk about the main difference: Mop P vs. MiJia 1C.
Design
The 1C is shorter because of not having Lidar on top. It can reach some places under furniture Lidar-guided robots can't.
Both robots are relatively quiet.
The Xiaomi Mop P comes with two bins, the 2-in-1 dustbin, and a separate dust container. The 2-in-1 bin is challenging to empty. I'd recommend using the separate dustbin if you are not going to mop. Besides, the 2-in-1 container leaks which might damage the robot if it stays on the charging dock for too long.
The MiJia 1C doesn't have leaking problems and you can not be worried about it sitting on the floor after it has done mopping.
Nevertheless, I would recommend removing the water tank after mopping is done for every robot vacuum.
The Xiaomi MiJia 1C has two separate containers for mopping and dust.
Mapping & Navigation
The most significant difference between the two would be mapping technology. The Mop P is lidar-guided, it has the LDS sensor on top that scans the surroundings and builds an accurate map of the room.
The MiJia 1C uses an optical (ToF) sensor, gyroscope, and accelerometer to build a map of a house.
If the Mop P creates a map based on scanning the room and it "sees" the area before going for cleaning, the MiJia 1C builds a map as it cleans which means it doesn't understand where to go next as it doesn't have the map of the cleaning area yet. It bumps into an obstacle and thus creates a rough map of the room it cleans.
After the first cleaning (or a few cleaning cycles for the 1C) when the map is created, both robots know where to clean and are more efficient.
Navigation
Because of being Lidar-guided, the Mop P is more accurate and gentle with furniture. On a daily basis, you will not notice the difference.
After the Mop P creates a map, it divides it into separate rooms in order to make the robot clean a specific room further. It allows merging or dividing some areas if you are not satisfied with the results.
Based on that map, you can schedule the robot to clean a certain room.
Because of having an accurate map, the Mop P finishes cleaning faster
The MiJia does not have a room cleaning feature.
To conclude
Because of Lidar, the Mop P creates an accurate map. This helps in cluttered homes with many furniture.
The MiJia is better to be used in homes with minimum furniture.
Mopping
The Xiaomi Vacuum Mop P has a dedicated Y-shape mopping pattern. It also can go back-and-forth if needed. The Y-shape does a better job at removing stains as it goes over the same spot twice but also spends more time to clean an area.
The Xiaomi 1C just moves back and forth. Also does the job well.
The Xiaomi Vacuum Mop P is better at mopping thanks to the Y-shape pattern it follows in mopping mode
During our tests, I noticed that the 1C consumes less water than most robots. Even after running it on max mode, you will notice that it still has enough water to cover the same area twice.
This means the 1C is ideal if you have a big area of hard floor to mop.
Other than that both robots do the job on hard floors, the Mop P might do it better but it would hardly be noticeable in day-to-day life.
To conclude
If you want the robot to remove stains, the Mop P would be a better buy but keep in mind, it spends twice as much time in the same area.
If you have a big area of hard floor to mop, go with the MiJia 1C.
Vacuuming
The MiJia 1C has stronger suction.
The Mop P comes equipped with two containers, a 2-in-1 water tank + dustbin and a 500 ml dustbin. The 2-in-1 is challenging to empty though. The MiJia has two separate tanks, one for dust and one for mopping.
The Xiaomi MiJia 1C performs better vacuuming carpets and hard floors. It picks up more debris than the Mop P
In our tests, the MiJia 1C was noticeable better at cleaning carpets. It does a better job on both low and medium-pile carpets including handling pet hair.
To conclude
If you have carpets, I would suggest getting the MiJia 1C.
The app
As I said before, the Mop P creates an accurate map that is better for cluttered homes. The 1C is a great decision for clean layouts.
Another thing is room cleaning. The Mop P can be ordered to clean a specific room or two and also can be scheduled to clean some parts of your home.
Both robots have the same cleaning modes and water output.
Another thing is the Mop P allows setting an unlimited amount of no-go zones and zoned cleaning. With the MiJia, you can create one no-go zone and one area to clean.
The Xiaomi MiJia 1C is more basic. It doesn't have as many smart features but it is a good cleaner for those who are not going to use the app often or don't have many areas for the robot to avoid.
Final thoughts
The Xiaomi Robot Vacuum Mop P is a good buy if you want a lidar-guided machine without having to pay more.
It has some flaws such as the poor ability to clean carpets especially medium-pile ones or leaking when the mopping tank is filled with water. If you don't have thick carpets and want the robot mainly to clean hard floors, the Mop P would be a good robot to buy.
The Xiaomi MiJia 1C is the best in its price range.
It does a better than average job on carpets and hard floors. Has decent mopping and some extra features none robot vacuum for the price has. If you have a clean layout with minimum furniture, the MiJia 1C is an ideal robot vacuum to buy.
