Dual side rotating brush
Dust is removed by the rotation of dual side brushes.
Threshold traveling
Approx. 1 cm of threshold can be traveled with special
driving system, therefore, all the rooms can evenly be
cleaned. However, for the sake of safety, the threshold of
more than 1 cm can not be crossed.
Soft bumping
Dust of every corner can be neatly cleaned by approaching to the
corner as much as possible through the minimizing of colliding
impact as the velocity is reduced by 7 obstacle sensors when
encountering with obstacle and through the relieving of the
colliding impact by 2 bumper sensors during the cleaning. (The
obstacle sensor displays higher sensitivity against bright obstacle.)
Safety device
If lifting the robotic vacuum cleaner while it is in operation,
the motions of driving wheel, power brush, suction motor,
and side rotating brush will be stopped due to the
detection of the sensor.
Remote controller
The robotic vacuum cleaner can easily be operated with
the remote controller.
