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 matter?

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.

This is why the MiJia 1C which lasts up to 40 minutes is not suitable for bigger homes.

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

The cheapest

Supports zoned cleaning and is equipped with a long-lasting battery.

 The Xiaomi Mi Robot is the first robot vacuum that was released in 2016. It is equipped with a HEPA filter that makes the robot safe for allergy and asthma sufferers. Equipped with 12 sensors including the LDS laser that helps to create a map of the cleaning area, the Xiaomi navigates in a back-in-forth pattern safely avoiding furniture and falling offs. 

Because of a processor inside you can track the Mi Robot movements in real-time by using the app. It helps to understand where the robot has been and where it needs to clean.

The Mi Robot supports zoned cleaning. It is helpful if you want the cleaner to pay attention to some areas more than to others.

Equipped with a 5,200 mAh battery, the robot lasts up to 150 minutes before needs to recharge covering about 2691 ft2 / 250 m2. 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.

Aside from the LDS laser, the robot also equipped with a visual sensor for a more precious mapping. It has a newer processor than the Mi Robot does that builds a map faster and helps to create a more efficient way of cleaning. 

It supports the same features the Mi Robot does and in addition, the robot has blocked off areas and can directly work in a specific room. Thanks to the visual sensor, the MiJia 1S recognizes rooms by dividing the map into separate rooms. When the map is created, you can schedule the cleaner to work in the kitchen/bedroom at a specific time. This option is useful if you don’t need to clean the whole house. 

The new MiJia 1S supports multi-floor which means it can save up to 3 maps and is suitable for multi-story houses. This feature is still in beta and might not work correctly.
