Problem
The robot does not clean
properly.
The rechargeable battery
can no longer be charged
or runs empty very fast.
Possible cause
The bumper is stuck.
The robot was lifted while it
was cleaning.
The bristles of one or both side
brushes are crooked or bent.
The filter in the dust container
is dirty.
The suction opening in the
bottom of the dust container is
clogged.
The front wheel is jammed
with hair or other dirt.
The robot is cleaning a very
dark or shiny surface, which
triggers the drop-off sensors.
This causes the robot to move
in an unusual pattern.
The robot is cleaning a floor
that reflects sunlight quite
strongly. This triggers the drop-
off sensors and causes the
robot to move in an unusual
pattern.
The rechargeable battery has
reached the end of its life.
Solution
Lift the robot so that its bumper comes
free. Place the robot at some distance
from the obstacle and press the
start/stop button to make it resume
cleaning.
Place the robot on the floor. Then press
the start/stop button to make the robot
resume cleaning.
Soak the brush or brushes in warm
water for a while. If this does not restore
the bristles to their proper shape,
replace the side brushes (see chapter
'Replacement').
Clean the filter in the dust container with
a cloth or a toothbrush with soft bristles.
You can also clean the filter and dust
container with a regular vacuum cleaner
at a low suction power setting.
If brushing or vacuuming does not help
to clean the filter, replace the filter with
a new one. We advise you to replace the
filter at least once a year.
Clean the suction opening (see chapter
'Cleaning and maintenance').
Clean the front wheel (see chapter
'Cleaning and maintenance').
Press the start/stop button and then
move the robot to a lighter colored
piece of the floor. If the problem
continues to occur on lighter colored
floors, please go to
www.philips.com/support or contact the
Consumer Care Center in your country.
Close the curtains to block sunlight from
entering the room. You can also start
cleaning when the sunlight is less bright.
Have the rechargeable battery replaced
by a Philips service center (see chapter
'Replacement').
