Problem Possible cause Solution
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.
The suction opening in the
bottom of the dust container
is clogged.
Clean the suction opening (see chapter
'Cleaning and maintenance').
The front wheel is jammed
with hair or other dirt.
Clean the front wheel (see chapter
'Cleaning and maintenance').
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.
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.
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.
Close the curtains to block sunlight from
entering the room. You can also start
cleaning when the sunlight is less bright.
The rechargeable battery
can no longer be charged
or runs empty very fast.
The rechargeable battery has
reached the end of its life.
Have the rechargeable battery replaced
by a Philips service center (see chapter
'Replacement').
The battery of the
remote control runs
empty too fast.
Perhaps you did not insert
the correct type of battery.
For the remote control, you need a
CR2025 coin-shaped battery. If the
problem persists, go to
www.philips.com/support or contact the
Consumer Care Center in your country.
The robot is moving in
circles.
The robot is in spot-cleaning
mode.
This is normal behavior. The spot-cleaning
mode can be activated when a lot of dirt
is detected on the floor for a thorough
clean. It is also part of the auto cleaning
mode. After approximately one minute
the robot resumes its normal cleaning
pattern. You can also stop the spot-
cleaning mode by selecting a different
cleaning mode on the remote control.
The robot cannot find the
docking station.
There is not enough room for
the robot to navigate
towards the docking station.
Try to find another place for the docking
station. See 'Installing the docking station'
in chapter 'Preparing for use'.
The robot is still actively
searching.
Give the robot around 20 minutes to
return to the docking station.
