Which one to buy if

What owners say

iRobot Roomba Max 705 owners who upgraded from older generations describe faster, more accurate LiDAR mapping that bumps into furniture far less, plus strong pickup of pet hair and carpet debris. They call the AutoEmpty dock a genuine convenience, letting the robot run for weeks without emptying the bin, and note it runs quieter than earlier Roombas. The recurring complaint is Wi-Fi setup, with the app rejecting router passwords that contain special characters, and a few mention the dock not fully clearing the onboard bin or a false stuck error.

Upgrading from the iRobot Roomba Max 705?

Moving up from the iRobot Roomba Max 705 to the iRobot Roomba Max 775 Combo Robot + AutoWash Dock buys two things: a mop and much more suction. The 775 adds a self-washing, self-drying pad with automatic detergent, lifts the rating to 30,000 Pa and runs longer, at the cost of weight and a slower recharge. If your iRobot Roomba Max 705 already covers a carpeted home and you never wanted a mop, there is nothing to gain; if you want hard floors cleaned in the same pass, the 775 is the step up.
