You can use the Roomy 4.0 virtual wall to define an area for cleaning. In this way, you can prevent the vacuum cleaner from passing into other rooms that cannot be closed with a door, or you can reserve a certain part of a large space (halls, spacious living rooms or connected living rooms with a kitchenette). The source of the virtual wall emits infrared rays that create a "virtual wall" and prevent the vacuum cleaners from moving further. The virtual wall is powered by two pieces of LR20/D type batteries, which are not included in the package. Package Contents: 1 x Virtual Wall; Dimensions: 100x95x40 mm; Color: black
