Rated for 200 minutes against 100, it shares the same 335 mm body, LiDAR mapping with multi-room maps and no-go zones, 2.4 GHz Wi-Fi, child lock and Alexa and Google Home support. What the iRobot Roomba 105 Combo adds is a mop for light daily wiping of hard floors, at the cost of half the runtime and a combo mode that steers around rugs rather than lifting the pad. Neither self-empties, so both bins are emptied by hand. Pick the iRobot Roomba 105 for vacuuming a whole small or medium home, and the iRobot Roomba 105 Combo if a quick damp pass on tile or hardwood is worth the shorter runs.

What the differences mean

Mopping

The iRobot Roomba 105 Combo adds a mop for a light damp pass on hard floors. It has no mop washing, drying or lifting, so you rinse the pad yourself and it avoids rugs in combo mode. The iRobot Roomba 105 only vacuums.

Runtime

The iRobot Roomba 105 runs 200 minutes, the iRobot Roomba 105 Combo 100. That is the real cost of the mop: owners of the vacuum-only model already mention recharging mid-clean in larger homes, and the Combo has half the time.

Everything else

Body size, LiDAR navigation, multi-room maps, no-go zones, Wi-Fi, child lock and the Alexa and Google Home support are the same on both. Neither supports Apple Home, SmartThings, Home Assistant or Matter, and neither self-empties.

Which one to buy if

What owners say

Owners of both Roomba 105 models praise the same LiDAR navigation that cleans in organised rows instead of wandering, solid everyday pickup of pet hair and dust, simple app scheduling and quiet runs, and both groups report a few battery or navigation problems months after purchase. iRobot Roomba 105 owners single out a bin that lasts a few days, and their main complaint is runtime that can fall short in a larger home, plus weaker results on thicker carpet. iRobot Roomba 105 Combo owners call the mop a helpful bonus for hard floors rather than a deep clean, and their complaints centre on a first map that takes several runs and manual edits and a combo mode that avoids rugs instead of switching to vacuum-only on them.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
