What the differences mean
Mop that is washed, or a wipe
The iRobot Roomba Max 705 Combo washes and dries its mop, lifts it, and doses detergent. The SwitchBot K11+ has none of those. Its water tank is not applicable because the mop is a pre-moistened pad, which owners describe as a wipe rather than a scrub. If the floor has to come out clean rather than freshened, the Roomba is the one doing that work.
Suction and runtime
The iRobot Roomba Max 705 Combo is rated at 13,000 Pa for 120 minutes. The SwitchBot K11+ is rated at 6,000 Pa for 150 minutes. The Roomba pulls harder and finishes sooner on the spec sheet. The SwitchBot simply stays out longer, which matters more in a small apartment than in a large house.
Size and noise
The SwitchBot K11+ is 248 mm square and 92 mm tall, with a dock of 240 x 180 x 250 mm, and it is rated at 45 dB. The iRobot Roomba Max 705 Combo is 372 x 366 x 105 mm, with a much larger dock, and its noise level is not documented. Owners of the Roomba do call it loud. The SwitchBot is the one that fits a tight corner.
5 GHz and the dust bag
The iRobot Roomba Max 705 Combo joins 5 GHz Wi-Fi. The SwitchBot K11+ does not. The other way around, the SwitchBot publishes a 4L dock bag and the Roomba's dock bag size is not documented. Both self-empty, and both support Matter, Apple Home, SmartThings, Alexa, Google Home and Home Assistant.
Which one to buy if
- you want the mop washed and dried for you
The iRobot Roomba Max 705 Combo washes, dries, lifts and doses detergent. The SwitchBot K11+ uses a wipe pad and does none of that.
- the home is a small apartment with tight furniture
The SwitchBot K11+ is a 248 mm square with a compact dock, rated at 45 dB, so it reaches chair legs the larger Roomba cannot.
- the Wi-Fi you can use is 5 GHz
The iRobot Roomba Max 705 Combo supports 5 GHz. The SwitchBot K11+ is 2.4 GHz only, though both support Matter.
- long hair and a short daily vacuum are the job
SwitchBot K11+ owners praise an anti-tangle brush and a self-empty dock that lasts weeks. It is also the longer rated run, 150 minutes against 120.

What owners say
Owners agree that mapping is easy and then split on what the robot is for. iRobot Roomba Max 705 Combo owners praise LiDAR zones, obstacle avoidance around cords and socks, and an extending roller that reaches edges, when the robot is behaving. They also describe false bin and water errors, a dirty-water tank that puddles, streaks on the floor, a buggy schedule, and support that feels scripted. SwitchBot K11+ owners single out the tiny body in chair legs and under low furniture, an anti-tangle brush that stays clear of long hair, and weeks between empties. They complain that the mop is only a damp wipe, that hair lingers at carpet edges, and that it can climb a ledge if the no-go zone is sloppy.
