The Dirt Detecting Radio Frequency Roomba 790

This is the dirt-detecting Roomba that can be scheduled or launched from another room. The Roomba 790 has a radio frequency remote control that transmits through ceilings and walls to set the robotic vacuum’s cleaning schedule from up to 25' away. It is the first of its kind to forego typical vacuum brushes and instead uses two rubber rollers that rotate in opposite directions and have angled treads that increase suction to ensure superior debris removal. Integrated optical sensors detect dirty areas and acoustic sensors determine when the vacuum is working harder, prompting Roomba 790 to concentrate on these areas. Made by iRobot, developers of tactical reconnaissance robots for the U.S. military, Roomba analyzes the dimensions of a room, determines the optimal cleaning path, and autonomously cleans the floor while navigating around furniture and stairs. The cleaning head automatically adjusts to accommodate carpets or hard floors and dual HEPA filters capture dirt particles as fine as 0.3 microns. It can be scheduled to automatically clean up to seven times per week or prompted to spot clean. Roomba automatically returns to its charging base when its battery runs low and the two included Virtual Wall lighthouses project infrared beams that confine the vacuum to one room and direct it to another room when it is finished cleaning. Includes extra HEPA filter and four C batteries for lighthouses. Only available for delivery in the U.S. and Canada. 14" Diam x 3 3/4" H. (8 1/2 lbs.)
