iRobot Roomba 105 Combo vs Shark PowerDetect ThermaCharged RV2920XE

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official iRobot and Shark sites.
2026 verdict
Both robot vacuums mop here, but only one automates the mess that comes after: the Shark PowerDetect ThermaCharged RV2920XE wins this comparison with a dock that washes and dries its own pads in hot water and empties the bin on its own, plus a longer battery life and a longer warranty than the iRobot Roomba 105 Combo. The Roomba 105 Combo pushes back with a lower price and a wider integrations list, adding IFTTT support on top of the Google Home and Alexa both robots share, but its mop uses plain water with no auto-washing or auto-drying, and its bin still needs emptying by hand. Navigation, obstacle and cliff detection, multi-room mapping, no-go zones and carpet cleaning are all matched between the two. Buyers who want a dock that truly looks after itself should go with the Shark PowerDetect ThermaCharged RV2920XE, while those who want to spend less and don't mind manual mop washing and bin emptying can stick with the iRobot Roomba 105 Combo.
