iRobot Roomba 205 vs iRobot Roomba Combo 10 Max robot + AutoWash dock

On features the iRobot Roomba Combo 10 Max robot + AutoWash dock wins: it mops, self-empties, adds Bluetooth and supports Alexa, HomeKit, Google, SmartThings, Home Assistant, IFTTT and Matter. The iRobot Roomba 205 is vacuum-only but is the more affordable option and carries the higher owner rating, so value shoppers may still prefer it.

Scope and navigation. The Combo 10 Max is a full vacuum-and-mop with a self-washing dock and huge integration list, while the 205 is a compact vacuum-only robot. The 205 uses LiDAR and works in the dark; the Combo uses a camera (VSLAM) that needs the lights on.

Only the Combo 10 Max does. The iRobot Roomba Combo 10 Max supports Apple HomeKit, Samsung SmartThings, Home Assistant and Matter, plus Alexa, Google Home and IFTTT. The iRobot Roomba 205 is limited to Google Home, Alexa and IFTTT.

Because it is cheaper, holds a higher owner rating, and its LiDAR maps the home even in the dark, whereas the camera-based Combo 10 Max struggles without lights. The 205's DustCompactor also skips the bulky tower for a small charging base.

Buy the Combo 10 Max if you want vacuuming and mopping in one hands-off machine with a self-washing dock and the widest smart-home support, including HomeKit and Matter, and you have good lighting for its camera navigation.

Choose the 205 if you want a lower-cost, vacuum-only robot with reliable LiDAR mapping that works in the dark and a compact dust-compacting design, and you do not need mopping or deep smart-home integrations.
