iRobot Roomba Max 775 Combo: Design and Features
The Max 775 has the familiar round Roomba shape, with a black and silver finish and two buttons on the top to start or pause a cleaning job and send the robot back to its base. At 14.7 inches long, 14.4 inches wide, and 4.1 inches tall, it’s larger than the average robot vacuum and weighs nearly 13 pounds.
Underneath are two rubber brushes that rotate in opposite directions. One agitates dirt to loosen it from the ground, while the other pulls debris toward the suction inlet. A pair of edge sweeping brushes direct dirt from walls and corners into your path.

The most distinctive features of the Max 775 are found in its mopping system. Its fabric-covered roller spins at 200 rpm, scrubs the floor while continuously washing to avoid spreading dirty water, and mechanically extends into the baseboards for better coverage. When the robot recognizes the carpet, it lifts the roller and closes a protective cover over it to prevent moisture from reaching the fibers.
The AutoWash Dock is a rectangular unit that measures 17.7 by 16.7 by 17 inches. Separate clean and dirty water tanks are stored beneath its hinged lid along with a dust bag compartment and a reservoir for iRobot’s StayClean cleaning concentrate.
The base automatically empties the robot’s trash container into an odor control bag. Also wash the mop roller with water heated to 167 degrees Fahrenheit and then dry it with warm air. Water and cleaning solution are dispensed automatically. iRobot claims up to three months of hands-free operation, although you’ll still need to refill the clean water tank periodically and empty the dirty tank after each cleaning job to avoid odors.
For navigation, the Max 775 combines LiDAR mapping with AI-assisted obstacle recognition. The Roomba Home app lets you schedule cleanings, select individual rooms, and adjust cleaning preferences. The app also offers hot water spot cleaning, allowing you to target a specific area on the map instead of cleaning an entire room.
