is successful, F9 will continue cleaning, and if repositioning fails, F9 will reclean this
area.
20. Why does F9 fail to reposition itself?
A : Moving F9 to an uncleaned area will cause repositioning failure. Ensure F9
is moved to a cleaned area.
If a person is standing next to the F9, it will fail to reposition itself. Do not stand
next to F9 and ensure the camera has full access to all feature points in the room.
F9 may fail to reposition itself in low lights. Please ensure sufficient light for
repositioning.
21. What is the max height of obstacles F9 can cross?
A : The F9 can cross obstacles up to 20mm high, which is shorter with water
tank installed.
The max obstacle height will also decrease when F9 is working on slippery floor.
22. Why does F9 fail to decelerate in face of obstacles?
A : The F9 is equipped with a LDS laser sensor to detect obstacles and decelerate
in advance. However, for dark table legs or short obstacles, collision may occur as
F9 is not able to detect them.
