When the battery is low, the robotic vacuum cleaner is
automatically guided to the charger to enable it to perform a
quick auto charge.
The edge-cleaning side rotating brush cleans dust from the
edges.
The robotic vacuum cleaner's innovative driving system
makes it possible for it to cross over doorsills with a height
About 1.5 cm
of about 1.5 cm and clean all rooms. The robotic vacuum
Vertical type
cleaner may not be able to pass a 1.5 cm doorsill depending
on the shape of the doorsill.
The robotic vacuum cleaner detects and avoids obstacles
in 2 stages. First, the 7 obstacle sensors detect obstacles in
stage 1 and if the robotic vacuum cleaner does crash into an
obstacle, the 2 bumper sensors absorb the impact.
When the robotic vacuum cleaner is lifted up while cleaning,
the driving wheels, power brush, suction motor, and side
rotating brush are stopped autonati(all) by sensor.
