Problem
The robot does not clean
properly.
The rechargeable battery
can no longer be charged
or runs empty very fast.
The robot cannot find the
docking station.
Possible cause
One or both side brushes are
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.
There is not enough room for
the robot to navigate towards
the docking station.
The robot is still actively
searching.
Solution
Clean the side brushes.
Press the start/stop button. 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 'Replacing
the side brushes').
Disassemble the filter unit. Clean the
dust filer and the EPA filter with a
toothbrush with soft bristles. You can
also rinse the dust filter under a tap.
If cleaning the EPA filter does not help
anymore, replace the filter with a new
one. We advise you to replace the EPA
filter at least once a year.
Clean the suction opening.
Clean the front wheel (see 'Cleaning the
robot').
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
'Replacing the rechargeable battery').
Try to find another place for the docking
station (see 'Installing the docking
station').
Give the robot around 20 minutes to
return to the docking station.
