About carrying the robotic cleaner
CAUTION
When you carry the robotic cleaner, stop the operation, then turn the
power off, and then hold the carrying handle firmly so as not to get your
hand caught.
• Not doing so can cause your hand to be caught in the handle.
Keep proper footing and balance at all times when lifting the robotic
cleaner.
• Not doing so can cause injury or failure.
Do not lift the robotic cleaner carelessly.
• Doing so can cause injury or failure.
Do not hold the robotic cleaner with its front facing downward.
• Dust can fall from the suction opening.
About cleaning by the robotic cleaner
• The robotic cleaner detects obstacles by its LiDAR sensor and ultrasonic sensor
and runs while avoiding those obstacles. It collects and sucks dust with its side
brushes and main brush. It may fail to recognize an obstacle depending on the
conditions. When it hits an obstacle, the bumper detects the contact and avoid
the obstacle.
• The robotic cleaner can climb over a step of up to about 2.0 cm. If it is less
than 2.0 cm, however, the robotic cleaner sometimes fails to climb over it
depending on the conditions such as the shape of the step.
• On a slope or an uneven place, the undersurface of the robotic cleaner may
be caught and a drive wheel may be lifted, which causes the robotic cleaner
to stop due to an error. If the robotic cleaner stops often, do not allow it to
enter that place. (See page 20.)
• Where there is an obstacle near a wall, the robotic cleaner may run up onto
the wall while trying to avoid the obstacle.
• The LiDAR sensor may not be able to recognize obstacles with the following
characteristics, which may result in inaccurate mapping or bumping into
obstacles.
- Highly reflective obstacles such as mirrors
- Highly transparent obstacles such as glass
- Obstacles made of black, glossy material
- Slim obstacles such as the legs of a chair or desk
• When the robotic cleaner enters a narrow space lower than the height of the
robotic cleaner, it can get caught and stuck. In such a case, place a screen or
something.

Block a gap with a screen or something.
• A black floor, a transparent floor such as a glass floor, or black areas on the
grain of wood flooring may be determined to be a step by the robotic cleaner,
which then tries to avoid it.
• The robotic cleaner may not be able to suck dust in an area around a step
over which the robotic cleaner can climb, a secluded or narrow space that the
robotic cleaner cannot enter, or a place that the side brushes cannot reach.
• The robotic cleaner may kick away a small, hard object such as a small stone.
• The robotic cleaner may climb over a step accidentally if there is an object
which can help it climbing up (for example, a board or carpet). Keep such
objects away from the steps.
CAUTION
Do not use the robotic cleaner in the following places.
• Do not use the robotic cleaner on places such as a carpet with a pile height of
more than 7 mm, a rug with piles that fall out easily, and an uneven rug.
On such a rug, the robotic cleaner may stop operating, piles may be caught in
the side brushes, or the rug or the side brushes may be damaged. If the robotic
cleaner cannot run well on a rug other than described above, avoid use on that
rug.
• Do not use the robotic cleaner on a mattress, a blanket, a floor cushion,
etc.
• Do not use the robotic cleaner in a wet area, a toilet, a bathroom, an attic,
outdoors, etc.
• Do not use the robotic cleaner in a wet place, a place that may become
wet, or in a hot, humid place.
To prevent the robotic cleaner from falling
WARNING
Ensure that the robotic cleaner does not fall.
• If it falls, it may cause breakage or injury.
• Do not use the robotic cleaner in a mezzanine floor, a loft, a stairwell, a place
without walls, or a place with a slope of 10° or more.
• In a place where an accident or other dangerous situation may occur due
to a fall, place an object that has a height of 25 cm or more and can serve
as a wall (object that does not move or topple over when hit by the robotic
cleaner).
