At the bottom of the vacuum cleaner are drive wheels, a swivel roller, side brushes and an oval-shaped hole for drawing in debris, here is a cover covering the battery compartment. There are sensors in the garbage collection hole to determine the amount of litter sucked in, due to which the vacuum cleaner determines the areas with the greatest pollution, where cleaning is carried out more thoroughly.

On the rear side of the case there is a large ventilation grille, on the bottom under the grille for attaching a napkin. During wet cleaning, the napkin is constantly kept wet by a drip system, water is supplied from a container.

The waste container is relatively large, located in the center and covered with a top cover. The garbage in it is carefully filtered, does not get outside, its amount does not affect the power of the vacuum cleaner.

The control system is implemented by touch buttons on the panel of the vacuum cleaner itself or buttons on the IR remote control. On the panel, you can select the operating mode, the remote control gives access to advanced settings — changing the mode, direction, programming the cleaning schedule.

The vacuum cleaner operates in 4 modes of operation, this list includes all standard modes and the zigzag movement, which its predecessors did not have, saves up to 25% of cleaning time, while capturing the maximum territory.

In the automatic mode, the robot surveys the room, selects the optimally suitable movement algorithm, and can change it during the cleaning process. It is best to move in a spiral in a large area, it starts from the center of the room with a gradual approach to the edge with an increase in the diagonal. In the mode of moving along the walls, the vacuum cleaner goes along the perimeter, if it stumbles upon an interior item, it moves along it.
