The Botvac D3Pro Connected is the perfect cleaning companion for apartments and smaller homes. It features LaserSmart mapping and navigation which continuously scans and maps each room. By doing so, Botvac D3Pro is able to clean quickly and efficiently while providing the most thorough coverage. The main brush works great on all surfaces and is 70% larger than those round robots1 providing an incredible clean. Plus, the ultra performance filter, captures dust and allergens too tiny to see. Once the robot is done, see where the robot has cleaned on the Neato app.
