iRobot iRobot Roomba i7+ i7558 can without any problem move over regular doorsteps in your home. This robot vacuum cleaner works best on hard materials, such as parquet or tiled floor. It can also vacuum short-haired carpets properly. Equipped with a HEPA-filter, the vacuum cleaner can clean your home thoroughly.
