Xiaomi has released three robot vacuum cleaners:

  1. Xiaomi Mi Robot (or the Xiaomi Robot Vacuum Cleaner)
  2. Xiaomi Mijia 1S Robot Vacuum (an upgraded version of the Xiaomi Mi Robot)
  3. Xiaomi Mijia STYJ02YM

The Xiaomi Mi Robot is the oldest robot vacuum in the family. In April 2019, released an improved version of this model — the Xiaomi Mijia 1S Robot Vacuum. It has an upgraded laser distance sensor and, in addition, a camera sensor with the AI image recognition that allows the 1S to recognize rooms and identify doors between these rooms, so now you can send a command to clean a specific room. Alongside with the Conrtex - A7 processor, it creates a more accurate map and has more advanced navigation algorithm. The company claims, the Xiaomi Mijia 1S provides more efficient cleaning, improved up to 13% compared to the first generation Xiaomi Mi Robot. The upgraded model can store multiple maps which makes it perfect for homes with more than one level. It also has a better suction power of 2,000Pa. 

In August 2019, the company produced the first 2-in-1 robot vacuum that can do mopping and sweeping, has stronger suction and bigger container.

What are digital virtual walls & restricted areas?

Virtual walls & restricted area is a feature that prevents the robot from going to certain areas such as cluttered zones or kids rooms. Overall, this option keeps the robot off unwanted areas.

What is zoned cleaning?

Zoned cleaning is needed when you need to vacuum high-traffic areas or messy zones. By drawing a rectangle on the map, you let the robot know where it should work. The feature is similar to the room cleaning, although zoned cleaning is more specific.

What is room cleaning?

The room cleaning is helpful when you don’t want to clean the whole house, only one or a few rooms. Once a robot creates a map, it divides the map into separate areas which you can merge or divide the way you want and even name each zone. Further, it will help the robot know where exactly to clean. You can also schedule the robot to work in a particular room or two at a specific time.

What is Lidar?

Lidar or the LDS laser is a technology that uses to build a map of a cleaning area. It scans the surrounding and creates a plan of the floor. Now the robot vacuum knows where it needs to clean. Mapping helps the robot to navigate more efficient since it doesn’t go over the same spots twice also saving battery life. Cleaners that are guided by Lidar finish cleaning faster. Xiaomi robot cleaners are equipped with the LDS laser. The Xiaomi MiJia 1S, in addition to the laser, has a visual sensor.

Robots that don’t have mapping bouncing around until their battery dies, they don’t learn your floor plan.

Why battery life matters?

Yes, it does matter if you live in an average to big size house. Normally the cleaners that have mapping cover more area for the same time the ones that randomly move do. If the robot that does not learn your home layout has 110 minutes of battery life does not mean it will cover the whole house on one charge while the one that remembers your floor plan will clean everywhere until it finishes the cycle.

The longer a robot lasts the more it will cover on one charge before finishing cleaning.

The Xiaomi Mi Robot and MiJia 1S run for the whole 2.5 hours while the latest Xiaomi STYJ02YM can do the job for up to 110 minutes which is also a good result but it would need more time to cover a bigger house.

What is recharge & resume?

When the battery runs lower than 20%, a robot automatically returns to the charging dock, juice up to 80% and then resumes cleaning from the same spot it left off. Mapping allows the robot to know where it has been so it knows exactly where it was before needed to go charging. This feature is useful for people who have big homes, it helps the cleaner to cover a bigger area on one charge.

The Xiaomi robot cleaners support recharging.

For Bare Floor

Other than battery life, the Mi Robot has a 15 mm climbing ability which makes it not suitable for thick carpets. It does have strong suction delivering 1,800 Pa but because of the wheels that can’t cross some obstacles, it is almost impossible for the vacuum to go on thick carpets.

Nevertheless, the Xiaomi Mi Robot does a superb job on bare floors and carpets, safe for those who suffer from allergy and asthma and is perfect for big houses.
