• If dirt or water droplets due to condensation are formed on the cliff sensor on
the undersurface of the robotic cleaner, wipe them off with a dry, soft cloth, a
cotton swab, etc.

• The robotic cleaner may fail to operate properly when exposed to sunlight
or infrared light from other equipment. Ensure that the robotic cleaner is not
exposed to infrared light from a halogen heater, a remote control, a sensor,
and other equipment and sunlight coming from frosted glass, etc.
• If there is a carpet, a mat, a plate, or other object near a step, the cliff sensor
may fail to recognize it as a step. Move rugs and other objects near steps.
• In such a place that the distance from a wall to a step is less than about 1 m,
the robotic cleaner may fall while moving backward. Do not use the robotic
cleaner where the distance from a wall to a step is less than about 1 m.

Less than about 1 m
• Where there is a drain cover (grating cover), the cliff sensor may recognize
it as a step and the robotic cleaner may not be able to pass over it. If it is
necessary to pass over it, cover the grating with a plate or something.
• A step of about 3.0 cm or less may not be recognized as a step by the cliff
sensor, resulting in the robotic cleaner climbing down the step while going
straight. Where there is a step of from about 2.0 to 3.0 cm, refrain from using
the robotic cleaner.
• Shut any sliding doors, screens, or windows because the level difference of
their frames or rails may not be recognized as a step by the bumper sensors.
• Do not use the robotic cleaner on a breakable flooring surface such as glass.
Tidying up a place to clean
WARNING
Move objects that may cause damage or an accident when the robotic
cleaner comes into contact with them.
Put away objects that should not be sucked in, objects that hinder the
movement of the robotic cleaner, and objects that are likely to get caught
in the main brush, wheels, and side brushes.
• If you leave an object that will obstruct the movement of the robotic
cleaner during cleaning, it may cause an accident or injury.
• Do not use the robotic cleaner near objects that get hot, such as a heating
apparatus (space heater). Doing so can cause an accident, ignition, or failure.
(Do not use a heating apparatus during operation.)
• Do not use the robotic cleaner in a place equipped with a retractable outlet. A
retractable outlet should be always retracted.
