This robot vacuum is equipped with 3 pairs of stair detection sensors (cliff sensors) near
the front edge under the vacuum, so it will not fall down stairs. These sensors need to be
cleaned regularly with dry cloths to remove any buildup of dust and dirt on their surface.
The front bumper needs to move freely without much resistance when you press and
release it. Check the bumper regularly and remove anything that might caught in
between the bumper and vacuum body.
If stair sensor or front bumper is not working properly, the vacuum will
keep
going
backwards
.
NOTE:
Black color floor (or floor with dark checker patterns, etc) and bright sun light could
cause confusion to stair sensors, and the vacuum will keep moving backwards under
these circumstances.
Hard Floor and Carpets
This robot vacuum cleaner works best on hard floors (hardwood, laminate, vinyl,
linoleum, tile, marble and stone, etc.)
It is not suitable for use on medium/long pile carpet or plush carpet.
