It is rated at 36,000Pa against 7,000Pa, its dock empties the bin and washes, dries and doses detergent for the mop, it slips under low furniture at 89.8mm and it works with every major smart home platform including Matter.

Height under furniture

What owners say

iRobot Roomba 105 Combo owners describe a budget vacuum-and-mop that handles daily dust, crumbs and pet hair, with LiDAR navigation that cleans methodically, straightforward app scheduling and real-time tracking, and quiet operation during runs. Their recurring complaints are about the first few mapping runs, which several say needed manual boundary edits, and about combination mode, where the robot avoids carpet rather than switching to vacuum only, while the mop is rinsed by hand because there is no washing or drying at the base. They also note there is no self-emptying dock, so the bin is emptied manually, and that a few owners saw reliability issues after several months.
