With the shark IQ robot self-empty, you can forget about cleaning for up to a month. After each cleaning session, your robot vacuum empties debris into a washable, bagless base, that holds up to 30 days of dirt and debris. Powered by IQ NAV, your robot vacuum now maps your whole home, allowing you to select which rooms to clean and which to avoid via the shark clean app or Amazon Alexa. The IQ robot methodically cleans row by row to assure total home cleaning, then navigates to the next room. When battery power is low, the IQ robot will automatically return to the base to recharge, then resume cleaning. And intelligence is just the start. It has a shark powerful Suction and a self-cleaning brush roll with dirt engage technology for 2X more direct contact on floors, with no hair wrap (as compared to the RV750). All debris goes into a self-empty base and the high-efficiency filter captures dust, debris, and pet allergens, down to one micron.
