Design
The shape of the robot vacuum cleaner body is square to capture the maximum cleaning area and space in the corners. The dimensions of the device are small, it easily fits into the narrowest and lowest places. The case height is only 74mm, which is much less than most competitors. The side view of the case shows its slight forward tilt, this modification allows you to clean under objects with a very low height.
The vacuum cleaner has a very unusual and stylish design. Color scheme - pure black or with white additives. On the upper part in the center there is a diamond-shaped cutout, below it are located the navigation sensors. There are control buttons and LED indicators near the sensors. If the LED lights up in blue, the vacuum cleaner is working in normal mode, if it lights up red, this is an error signal. There is a small cutout on the front of the case, under which obstacle sensors are located.
The front panel is equipped with a rubber bumper to protect the instrument from collisions. The bumper has a pair of sensors that react to a collision from the side or front.
Functional
The robot incorporates all the latest developments of the company's engineers - it is an intelligent device that effectively copes with indoor cleaning. A large number of sensors allows you to make an overview of the room, build a map for optimal movement around it.
The main element in the control system is the NorthStar Cube beacon. It is placed on a hill in a room that needs cleaning. The unit sends infrared rays, they are reflected from the ceiling and help in studying the room and determining its position in it. You can run the vacuum cleaner for cleaning without turning on the beacon, but in this case the process will go slower.
Dry cleaning is carried out in motion along a parallel path. Front-mounted sensors allow you to recognize obstacles in the way. The vacuum cleaner cleans up the entire free area, and then moves along the perimeter of the room along the walls and furniture. There are height difference sensors on the body, the robot does not fall from steps or thresholds. When the vacuum cleaner finishes cleaning, it beeps and goes into sleep mode.
When performing wet cleaning, the vacuum cleaner moves along a trajectory in the form of two parallel zigzags resembling a herringbone. For wet wiping, a damp cloth is used, water is supplied to it from a special reservoir.To replace the napkin, press the Pause button on the robot.
