To know more about the differences between all the Roborock robot vacuum cleaners click here.

Mapping technology

The Roborock S5: it uses LIDAR with an LDS laser located inside its tower. It scans the room creating a map and three processors inside help the robot to build the most efficient way of cleaning. The plan can be seen on the app. The robot saves one created map.

Xiaowa E20: it is equipped with a double gyroscope inertial navigation system, combined with dual optical motion tracking. The robot recognizes walls and corners and creates a map. The map shows the obstacles and barriers that were identified by sensors. It is not as detailed as the one generated by the laser nevertheless the Xiaowa's maps are more or less accurate. You can see the map on the app. Unfortunately, you can't do anything with the plan. Every time the robot cleans the map gets regenerated once again.

Additional features

The Roborock S5: the app allows to create virtual boundaries as many as you'd like to. There is also an ability to set zoned cleaning to make the vacuum working within the areas you've chosen. You can tap on the map to send the device to a specific point.


The Roborock S5 and Xiaowa E2: the water tank can be inserted by sliding it underneath. It holds about 150 ml of water and can work in this mode for about 60 minutes until the container gets dry.

Unfortunately, the manufacturer didn't mention how much of the liquid the Roborock Xiaowa's water tank holds.

  • The Roborock Xioawa is a bit louder than the Roborock S5
  • Virtual walls and zoned cleaning can be set only in the Roborock S5
