iRobot Roomba 205 vs iRobot Roomba Max 705 Combo

On capability the iRobot Roomba Max 705 Combo wins, since it vacuums and mops, self-empties, dispenses detergent and supports Alexa, HomeKit, Google, SmartThings, Home Assistant, IFTTT and Matter. But the iRobot Roomba 205 is cheaper, runs longer at 120 minutes and holds a higher owner rating, so budget-focused buyers may still favor it.

The Max 705 Combo mops and the 205 does not. The Combo pairs vacuuming with a self-cleaning roller mop, detergent dispensing and an AutoWash dock, while the 205 is vacuum-only and compacts dust internally to reduce emptying.

The iRobot Roomba 205 runs about 120 minutes and is the more affordable option, whereas the iRobot Roomba Max 705 Combo runs roughly 75 minutes. The Combo justifies its higher cost through mopping and a self-washing dock, not runtime.

The Max 705 Combo, decisively. It works with Alexa, Apple HomeKit, Google Home, Samsung SmartThings, Home Assistant, IFTTT and Matter, while the iRobot Roomba 205 is limited to Google Home, Alexa and IFTTT.

Buy the Max 705 Combo if you want one machine to vacuum and mop hands-off, with a self-washing dock, detergent dispensing, 13000Pa suction and the broadest integrations including HomeKit and Matter.

Choose the 205 if you only need vacuuming, want longer runtime, a higher rating and a lower price, and prefer a compact DustCompactor base over a large AutoWash tower and mopping you may not use.
