Under the mop pad it is the iRobot Roomba 105, with the same LiDAR navigation, obstacle and cliff detection, multi-room maps and no-go zones, the same 7000Pa suction, a 120 minute battery that recharges in 5 hours, and Alexa and Google Home support. The Combo adds a water tank and a mop that accepts detergent, which is the reason to choose it for kitchens and hard floors. The iRobot Roomba 105 is the more affordable, and for carpet-heavy homes that would never use a mop it is the sensible saving. Neither has a self-emptying dock or mop washing, so both bins and the Combo's pad are emptied and cleaned by hand. Choose the iRobot Roomba 105 Combo for mostly hard floors, and the iRobot Roomba 105 for vacuuming only.

What the differences mean

Mopping

The iRobot Roomba 105 Combo carries a water tank and a mop that works with detergent, so it wipes hard floors after vacuuming them. The iRobot Roomba 105 only vacuums. The mop is not lifted or washed automatically, so you remove and clean the pad yourself.

Rugs

Because the Combo cannot lift its mop, owners report it steers around carpets and rugs while mopping. The vacuum-only Roomba 105 has no such limit and cleans them on every run.

What stays the same

Suction, LiDAR navigation, battery life, charging time, size and smart home support are identical, so the choice is the mop against the lower price.

Which one to buy if

What owners say

Owners of both Roomba 105 models agree on the essentials: LiDAR navigation that cleans in tidy rows instead of bumping around, everyday suction that handles dust, crumbs and pet hair well, simple app scheduling and quiet runs. Both groups also report a few reliability problems months after purchase. iRobot Roomba 105 owners like how long the bin goes between emptyings, but many say the battery runs out partway through a larger home and that suction drops on thicker carpet. iRobot Roomba 105 Combo owners call the mop a welcome bonus on hard floors, and their complaints center on mapping: a first map that took several runs or manual editing, getting stuck near thresholds and door tracks, and a combo mode that avoids rugs rather than vacuuming them.

Upgrading from the iRobot Roomba 105?

Going from the iRobot Roomba 105 to the iRobot Roomba 105 Combo adds a mop and nothing else: suction, battery, navigation and app are unchanged. It is worth it if a lot of your floor is hard surface and you currently mop it by hand. If your home is mostly carpet, or you already use a separate mop you are happy with, the Combo will not clean any better than the robot you have.
