What the differences mean

Battery life

The iRobot Roomba Combo 10 Max robot + AutoWash dock is rated at 175 minutes per charge, while the iRobot Roomba 705X is rated at 120. On a large single floor that is the difference between finishing in one pass and stopping to recharge.

Navigation sensor

The iRobot Roomba 705X maps with LiDAR, so it works in the dark and builds a map quickly. The iRobot Roomba Combo 10 Max robot + AutoWash dock uses a camera instead, which needs light to navigate and can struggle at night.

Mop hardware

The iRobot Roomba 705X uses a PowerSpin roller mop that its dock washes with heated water and dries with hot air. The iRobot Roomba Combo 10 Max robot + AutoWash dock washes a flat pad and mops more like a wet wipe than a scrub.

Connection

The iRobot Roomba Combo 10 Max robot + AutoWash dock and the iRobot Roomba 705X both list Bluetooth and join the 2.4 GHz and 5 GHz Wi-Fi bands, so setup is much the same on either.

Which one to buy if

What owners say

Owners of the iRobot Roomba Combo 10 Max robot + AutoWash dock are split, and the happy ones describe excellent mapping, a dock that empties the bin, washes and dries the mop pad and refills water, and quieter running than the older J7+ with only a brief loud self-emptying burst. The recurring theme is reliability: many report several good weeks or months followed by jobs that stop partway, a robot that cannot find its dock, a battery that dies feet from home, and repeated bin and dirty-water errors. Because it navigates with a camera rather than LiDAR, owners note it needs the lights on and struggles in the dark, and several describe slow customer service for a device at this price tier.
