iRobot Roomba 505X vs iRobot Roomba Max 705 Combo

The iRobot Roomba 505X is the safer choice for most buyers: it is cheaper, runs 120 minutes versus 75, and holds a much higher owner rating, while still vacuuming, mopping and self-washing at an AutoWash dock. The iRobot Roomba Max 705 Combo wins on integrations, Bluetooth and detergent dispensing.

Value versus features. The 505X delivers a higher rating, longer runtime and lower price with the same core vacuum-and-mop and self-washing dock, while the Max 705 Combo adds a detergent roller mop, higher rated suction and broader smart-home support.

Yes. Both the iRobot Roomba 505X and the iRobot Roomba Max 705 Combo vacuum and mop, self-empty and wash and dry their mop pads at an AutoWash dock, using LiDAR to map the home.

The Max 705 Combo. It adds Bluetooth and works with Alexa, Apple HomeKit, Google Home, Samsung SmartThings, Home Assistant, IFTTT and Matter, while the iRobot Roomba 505X supports Alexa, Google Home and Apple HomeKit.

Buy the 505X if you want the better-rated, lower-priced vacuum-and-mop with a longer 120-minute runtime and a self-washing AutoWash dock, and you do not need Matter, SmartThings or detergent dispensing.

Choose the Max 705 Combo if you specifically want a detergent-dispensing roller mop, a 13000Pa suction rating and the widest integrations, including HomeKit, SmartThings, Home Assistant and Matter.
