Robotic vacuum cleaner Wolkinz COSMO uses laser range-finder and ultrasound radar for construction of the premise map; it scans the environment around robot at 360 degrees with sampling frequency 2400 times per minute. Robot constructs the map of the premise according to Slam LIDAR algorithm, divides regions and optimizes the cleaning route regardless the already cleaned areas not repeating moving along them. Thanks to precision sensors robotic vacuum cleaner Wolkinz COSMO calculates and defines the size and volumes of the objects on the floor, distance to the barriers and optimizes the route in real time to guarantee efficient cleaning in every corner of your house.
