The Roomba 615 features a patented 3-stage cleaning system with counter-rotating brushes and powerful suction to remove dirt, dust, hair, and other debris from your floors. The Roomba 615 is easy to use – simply press the Clean button, and thanks to iRobot's iAdapt Responsive Navigation Technology, the Roomba moves safely through the room. This ensures a thorough cleaning of the entire area. Like all Roomba models, the Roomba 615 has a rotating side brush that reaches right up to the walls. Its compact size allows it to access every corner, even under furniture. It navigates around obstacles precisely, detects stairs and ledges, and automatically returns to its Home Base to recharge between cleaning sessions.
