The E20 robot vacuum collects various types of debris from the floor, such as hair. Since hair can be long and prone to tangling, the roller brush may become entangled as it rotates while the robot performs cleaning tasks.

Q1: How does the robot remove hair entangled on the roller brush?

• While cleaning, the robot employs adjustable comb teeth to straighten the hair on the roller brush and gather it into the dustbin. During the dust collection process, the roller brush will self-clean by rotating both forward and backward. The self-cleaning process takes 19 seconds in Standard mode and 77 seconds in Deep Dust Collection mode.

Q2: What can I do to improve my robot's anti-tangle performance?

• For a spacious home with several pets or significant foot traffic, it is advisable to set the robot vacuum to automatically self-empty every 15 minutes or enable Deep Dust Collection mode.

• When running the robot for the first time, it will automatically set to Standard mode for deep dust collection, requiring 77 seconds to gather debris. Please note that choosing "I have pets" will prompt the robot to automatically empty dust every 15 minutes. On the other hand, choosing “I don't have pets” will prompt the robot to automatically empty dust every 30 minutes.
