What the differences mean

Battery and recharge

The iRobot Roomba Max 775 Combo Robot + AutoWash Dock is rated for 180 minutes per charge against 120 on the iRobot Roomba 705X, though it takes about 6 hours to refill where the 705X takes about 4.5.

Rated suction

The iRobot Roomba Max 775 Combo Robot + AutoWash Dock lists 30000Pa of suction. iRobot publishes no figure for the iRobot Roomba 705X, so on this line only one side can be read.

Radios

Both list Bluetooth. The iRobot Roomba 705X supports 5 GHz Wi-Fi, while iRobot's own sources disagree about whether the Max 775 does.

Dock and mop care

Both wash and dry the mop at the dock and dispense cleaning solution, and the iRobot Roomba 705X empties the robot for up to 75 days. The Max 775 does not publish an emptying interval.

Price

The iRobot Roomba 705X is the lower priced of the pair in the listings, which is the one reason to choose it over the newer and slightly better equipped iRobot Roomba Max 775 Combo Robot + AutoWash Dock.
