iRobot Combo Vacuum-Mops Ranked by Dock and Mopping Tech

Best for
Small homes with mostly hard floors

The iRobot Roomba 105 Combo Robot Vacuum is the only model here whose dock just empties the bin. The AutoEmpty dock stores up to 75 days of debris in a bag rated to trap 99% of allergens down to 0.7 microns. Mopping uses a washable microfiber pad kept evenly damp by a micro-pump, and SmartScrub adds 2x deeper scrubbing on demand.

On the vacuum side it uses 70X more power-lifting suction than iRobot’s older models, an edge-sweeping brush that cleans corners 20% better and a multi-surface brush. ClearView LiDAR maps rooms, and the robot detects carpets and avoids them while mopping so rugs stay dry. It offers vac only, mop only and combo modes, 7 power levels and control by app, voice or buttons. Battery life is listed at 100 minutes. It suits a dorm, a studio or a gaming room with hard floors, where rinsing a pad by hand now and then is no big deal. If you want the mop cleaned for you, skip to the Plus 415.

Best for
Large homes and heavy foot traffic

Best for
Multi-pet homes wanting top automation

The iRobot Roomba Max 775 Pet Robot is the most powerful and most pet-focused combo in the lineup. It lists 30,000Pa of suction, dual rubber brushes that resist tangling from pet and long hair, and enhanced pet-object AI with pet zone cleaning. PrecisionVision AI and ClearView Pro LiDAR steer it around cords, shoes and pet waste while building detailed 3D maps.

Mopping is handled by the PowerSpin Roller Mop, which cleans itself mid-run with 167 degree Fahrenheit water and a built-in scraper, and a roller mop cover lifts to shield it over carpet. Heated spot mopping with 200 RPM scrubbing works on dried spills near food bowls and doorways. The dock empties debris for up to 3 months, washes at 167 degrees, dries at 122 degrees and dispenses solution. The title calls it a multifunction dock while the features call it an AutoWash Dock, and the listed 39.3 pound weight likely includes the dock. Battery life is 180 minutes. Choose it for multi-pet homes that want the least maintenance possible.

• 30,000Pa suction with anti-tangle rubber brushes
• Heated self-cleaning roller mop and mop cover
• Pet-object AI and pet zone cleaning
• Up to 3 months hands-free emptying

Best for
Edge mopping with a pad-washing dock

The iRobot Roomba Plus 505 Combo Robot brings spinning DualClean Mop Pads with PerfectEdge, which extend along walls for 18% more mopping coverage, plus SmartScrub for 2x deeper scrubbing on coffee and grime. The pads lift automatically when the robot senses carpet ahead. On the vacuum side it claims 70x more suction than Roomba 600 series robots, with Carpet Boost, a multi-surface rubber brush and an edge-sweeping brush.

The AutoWash Dock handles 75 days of auto-emptying, 4 weeks of mopping and pad washing based on one mopping run per week, continuous pad refreshing and heated drying. PrecisionVision AI spots cords, socks and pet waste and can identify wet and dry messes for repeat passes. You get 4 cleaning modes, including vacuum first then mop, and 4 suction levels in the Roomba Home app. Battery life is 120 minutes. It suits readers who want a washing dock and good edge coverage in a medium home. For more suction and longer runtime, the Plus 575 is the upgrade.

The iRobot Roomba Plus 415 Robot Vacuum packs a full-service dock into a more modest package. It lists 20,000Pa suction, DualClean Mop Pads with SmartScrub pressure for dried food and muddy paw prints, and tangle-free rubber brushes aimed at pet fur. The title rates the dock at 90 days of self-emptying, and it also washes pads, heat-dries them at 113 degrees after every run and refills the robot’s water.

Its body is 46% slimmer than the Roomba Plus 405 Combo, helping it slip under more furniture, and extending brushes pull debris out of edges and corners. LiDAR mapping and obstacle recognition handle cords, shoes and toys. The mop pads lift 10mm before crossing rugs, and you get four cleaning modes: vacuum only, mop only, both at once, or vacuum then mop. Battery life is listed at 202 minutes. The spec sheet lists app control as the controller type while the control method adds voice. This is the smart pick for pet owners who want washing and refilling without flagship extras. It lacks the heated spot mopping and roller mop of the Max models.

• 20,000Pa suction, pet-friendly rubber brushes
• Dock empties, washes, hot-dries and refills
• Lifts mop pads 10mm over carpet
• 202-minute listed battery

The iRobot Roomba Max 775X Combo Robot is the Max-series sibling of the 775 Pet, with the same core hardware: PowerSpin Roller Mop with 167 degree self-cleaning and scraping, a retractable roller mop cover, heated spot mopping at 200 RPM, extended mopping with dual edge brushes, dual anti-tangle rubber brushes, ClearView Pro LiDAR and PrecisionVision AI.

Its AutoWash Dock empties debris for up to 3 months, washes at 167 degrees, dries at 122 degrees and dispenses solution, and it uses carbon odor-control AllergenLock bags. Battery life is 180 minutes. Instead of a Pa figure, the listing gives relative suction: 3.8X in the features and 4X in the description, both against an earlier model. It suits large, busy homes with lots of foot traffic. If pets are your main concern, the 775 Pet highlights 30,000Pa suction and pet zones more clearly. For a broader look at the Max lineup, see our Roomba vacuum and mop combo rankings.

The iRobot Roomba Plus 575 Robot Vacuum is the top of the Plus line. It lists 25,000Pa suction with a rubber and bristle brush and a 3-prong side brush tuned for heavy shedders. Its body is 46% smaller than the Roomba 505, and it climbs thresholds up to 35mm, which helps in homes with raised doorways between rooms.

Lifting spinning mop pads with SmartScrub and DualClean extend 35mm on an articulating arm for 18% more edge coverage under toe kicks and along walls. The dock empties for up to 3 months, auto-refills the robot for up to 40 days of mopping, washes pads at 167 degrees and hot-air dries them at 113 degrees. PrecisionVision AI avoids cords and shoes, and battery life is listed at 202 minutes. It is the pick for medium to large homes with low furniture. The Max models still offer the roller mop and heated spot mopping for stubborn stains.
