Size, 120 minute battery, charging time, mapping, no-go zones, child lock and Alexa and Google Home support are identical, and neither has a self-emptying dock. The iRobot Roomba 105 Combo is rated at 7000Pa, while iRobot does not publish a suction figure for the iRobot Roomba 105X. The mop uses water only and cannot lift, so in combo mode the robot steers around rugs. Choose the iRobot Roomba 105 Combo for hard floors that need a light wipe, and the iRobot Roomba 105X for carpet-heavy homes that only need vacuuming.

What the differences mean

Mopping

The iRobot Roomba 105 Combo mops with water on hard floors, a light wipe rather than a scrub. The iRobot Roomba 105X has no mop at all.

Rugs in combo mode

The iRobot Roomba 105 Combo cannot lift its pad, so when it mops it avoids carpet and rugs. For a carpet-heavy home, that makes the mop less useful than it sounds.

Everything else

Same 335 x 335 x 104 mm body, same 120 minute battery and 5 hour charge, same LiDAR mapping and no-go zones, same Alexa and Google Home support. Beyond the mop, you would not tell them apart.

Which one to buy if

What owners say

Owners of both Roombas praise LiDAR navigation as methodical next to older bump-and-go robots, and everyday pickup of dust and pet hair. iRobot Roomba 105 Combo owners single out the mop as a helpful bonus on hard floors, but describe first maps that take several runs and manual correction, and a robot that avoids rugs in combo mode instead of switching to vacuum only. iRobot Roomba 105X owners talk about the automatic switch between carpet and hard floor, while their complaints are battery life falling short in larger homes, getting caught on cords and mats and side brush arms wearing after repeated snags.

Upgrading from the iRobot Roomba 105X?

The iRobot Roomba 105 Combo is the iRobot Roomba 105X with a water mop added. Moving up gives you a light wipe on hard floors and nothing else: the same body, battery, mapping and app. If your 105X already keeps a mostly carpeted home clean, there is no reason to switch; if you have tile or wood that you mop by hand, the Combo takes over part of that job.

Frequently Asked Questions

Which is better overall: iRobot Roomba 105 Combo or iRobot Roomba 105X?

No. The iRobot Roomba 105 Combo cannot lift its mop pad, so in combo mode it avoids carpets and rugs. It uses water only, with no mop washing or drying.

Do the iRobot Roomba 105 Combo and the iRobot Roomba 105X empty themselves?
