The robot vacuum cleaner features a retractable brush and an adaptive edge cleaning system. The mechanical brush automatically adjusts to the contours of obstacles, ensuring a tight fit against walls and furniture. With a 68% larger coverage area, the device effectively cleans narrow crevices under furniture and appliances, as well as refrigerators and beds. The system handles difficult areas like curved walls, contoured baseboards, and rounded objects without getting stuck. This allows it to cover up to 83% more area than conventional models, ensuring a complete clean along the entire perimeter of the room without any gaps.
