It vacuums, mops, and handles most of its own cleanup, leaving you with relatively little to do beyond occasional maintenance. But more automation doesn’t necessarily mean cleaner floors. All those hands-free features count for little if a robot leaves dirt or stubborn stains behind. Fortunately, the Max 775 delivers on both fronts, combining excellent cleaning performance with automation that makes keeping your floors spotless genuinely easier. 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 top for starting or pausing a cleaning job and sending the robot back to its dock. 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 floor, while the other pulls the debris toward the suction inlet. A pair of edge-sweeping brushes directs dirt from walls and corners into their path. The Roomba Max 775 has a sleek, low-profile design with two top-mounted buttons for starting a cleaning job and returning the robot to its dock. Michael Ansaldo/Foundry The Max 775’s more distinctive features are found in its mopping system. Its fabric-covered roller rotates at 200 rpm, scrubbing the floor while continuously washing itself to avoid spreading dirty water, and mechanically extends toward baseboards for better coverage. When the robot recognizes carpet, it raises the roller and closes a protective cover over it to prevent moisture from reaching the fibers. The AutoWash Dock is a rectangular unit measuring 17.7 by 16.7 by 17 inches. Separate clean- and dirty-water tanks are stowed beneath its hinged lid along with a dust bag compartment and a reservoir for iRobot’s StayClean cleaning concentrate. The dock automatically empties the robot’s dustbin into an odor-control bag. It also washes the mop roller with water heated to 167 degrees Fahrenheit, then dries 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 one after each cleaning job to prevent odors. For navigation, the Max 775 combines LiDAR mapping with AI-assisted obstacle recognition. The Roomba Home app lets you schedule cleanings, target individual rooms, and adjust cleaning preferences. The app also offers heated-water spot cleaning, letting you target a specific area on the map rather than cleaning an entire room. The Roomba Max 775 uses two counter-rotating rubber brushes to lift dirt and debris, while its roller mop extends outward to clean along walls and baseboards. Michael Ansaldo/Foundry iRobot Roomba Max 775 Combo: Setup and performance The AutoDock comes fully assembled so you need only to find some space for it. iRobot recommends 1.6 feet of clearance on either side and 5 feet in front. The Roomba Home app handles Wi-Fi pairing. It instantly recognized the Roomba and guided me through the setup with a series of short prompts. The first time you use the Max 775 it does a mapping run of your space without vacuuming. It took less than 15 minutes to map my home’s layout and got it mostly right, though I had to divide one room into two and rename them using the map editing tool. The Roomba Home app offers plenty of control without overcomplicating cleaning jobs. You can vacuum, mop, do both simultaneously, or vacuum first and mop afterward. Cleaning presets include Light, Standard, and Deep, which apply progressively more aggressive cleaning settings, and Smart, which automatically adjusts the settings for each room based on how dirty it is. You can also select individual rooms and arrange them in your preferred cleaning order. The app also automatically identified specific cleaning zones within rooms, including areas around my sofa, dining table, refrigerator, and toilet. You can clean these areas individually and customize their settings just as you would for an entire room. Options include suction power, the amount of water dispensed, one or two cleaning passes, and whether to use SmartScrub, a feature that uses extra back-and-forth scrubbing passes and downward pressure to tackle stubborn dirt. That allows you to give a particularly dirty area a more thorough cleaning without applying the same settings throughout the house. The AutoWash Dock’s removable clean-water tank has a separate compartment for iRobot’s StayClean cleaning concentrate. Michael Ansaldo/Foundry For smaller messes, Spot Clean lets you target a specific area on the map, with an option to use heated water for mopping. You can also schedule cleanings and access saved routines from the home screen. Separate dock controls let you wash and dry the mop or empty the dustbin manually when needed. During my testing, the Max 775 consistently handled dust, cat hair, and food crumbs on my laminate floors without leaving visible debris behind. It cleaned well along baseboards and in corners, often a weak spot for round vacuums. During combined vacuum-and-mop runs, the robot alternated between the hard floors and area rug in my living room. The rug always stayed dry, suggesting the protective mop cover was working as intended. Mopping was generally effective against tracked-in dirt, kitchen grease, dried spills, and general buildup. Some shoe scuffs were more stubborn and standard mopping left some marks behind, but switching to SmartScrub removed them completely. The floors looked evenly cleaned afterward with no visible streaks. The Max 775 has excellent obstacle detection. Throughout my testing, it maneuvered deftly around the array of obstacles I left out to challenge it, including pet beds, laundry baskets and several pairs of shoes along with all my home’s furniture. It never got stuck or knocked anything over, which gave me the confidence to let it run unattended most of the time, and it consistently found its way back to its dock. The AutoWash Dock’s removable clean-water tank has a separate compartment for iRobot’s StayClean cleaning concentrate. Michael Ansaldo/Foundry The dock empties the robot’s dustbin after cleaning jobs, and sometimes during them depending on how fast it fills up. Similarly the dock washes the mop after wet cleaning and dries it with warm air over the roller, rotating it every 15 minutes to expose different sections to the airflow. iRobot doesn’t say how long it takes to completely dry the roller, but several hours seems to be the norm based on the low hum the dock emits during the process. Should you buy it? I was pretty happy with the results I got from the Max 775. It consistently returned a gleam to my floors without requiring much hands-on attention from me, which is exactly what you want in a robot vacuum. While any home can benefit from such a helper, I’d say the Max 775 is particularly well-suited for busy households with pets and a mix of hard floors and carpeting. If you mostly need occasional vacuuming, you could get away with spending less on a simpler robot.
