Brand note
iRobot does not publish a Pa suction rating on this listing; the bullets claim '70x the suction' versus iRobot's own older 600-series robots, which isn't a comparable spec to the Pa figures other brands publish.

Full review
The Roomba 105 Combo brings ClearView LiDAR and a 75-day AutoEmpty dock into iRobot's value combo tier. Its standout feature versus most other products here is automatic carpet avoidance while mopping — rather than lifting the mop pad on a schedule, it detects carpet and simply won't wet it. A SmartScrub mode doubles the scrubbing depth for tougher stains, and cleaning can be split into vacuum-only, mop-only, or combined passes.
iRobot doesn't publish a suction figure in Pascals the way Roborock, Tikom and eufy do on their listings, so it can't be directly suction-ranked against those products — though its 49,337 reviews at 4.4 stars is one of the strongest combinations of scale and rating in this entire catalog.
