iRobot Roomba 105X vs Shark PowerDetect ThermaCharged RV2920XE

The Shark PowerDetect ThermaCharged RV2920XE is the pick overall, ahead on owner rating, warranty length and its full self-washing, self-drying mopping package with a self-emptying dock. It is a genuinely close call though: the iRobot Roomba 105X wins on price, battery life and smart-home integrations, so shoppers who don't need mopping have a strong budget alternative in the Roomba 105X.

The Shark PowerDetect ThermaCharged RV2920XE mops as well as vacuums, with auto mop washing, auto mop drying and a self-emptying dock built in. The iRobot Roomba 105X is vacuum-only, with no mopping, no detergent compatibility and none of the auto mop features, and it has no self-emptying dock, so its bin has to be emptied by hand.

The iRobot Roomba 105X runs longer per charge, rated for around 200 minutes versus 180 minutes for the Shark PowerDetect ThermaCharged RV2920XE. Both robots support auto-recharge to return to their dock when the battery runs low.

The iRobot Roomba 105X supports more integrations overall, adding IFTTT on top of the Google Home and Alexa voice control that both robots share; neither model connects to Apple HomeKit, Samsung SmartThings or Matter. The Shark PowerDetect ThermaCharged RV2920XE instead carries the longer warranty, covered for 2 years versus 1 year on the iRobot Roomba 105X.

Buyers who want dependable, room-specific LiDAR vacuuming at a lower price, without paying for mopping, should choose the iRobot Roomba 105X. It also suits anyone who values longer per-charge battery life or wants the widest smart-home integration support in this pair.

Buyers who want vacuuming and mopping handled by one robot, with a self-washing, self-drying mop pad and a self-emptying dock, should choose the Shark PowerDetect ThermaCharged RV2920XE. Its higher owner rating and longer warranty make it the pick for anyone prioritizing an all-in-one, hands-off cleaning routine over the lowest price.
