iRobot Roomba 105X 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
Rating, warranty and a full self-washing mopping package carry the Shark PowerDetect ThermaCharged RV2920XE in this robot vacuum matchup, one of the closest fights the iRobot Roomba 105X has had all year.
The iRobot Roomba 105X counters with two real wins of its own: a lower price and support for more smart-home integrations, though its 120-minute battery trails the Shark's 180 minutes. Connectivity, navigation, obstacle and cliff detection, multi-room mapping, no-go zones and carpet cleaning all come out even between the two, so the gap really comes down to what mop pad washing, drying and a self-emptying dock are worth to a buyer. Shoppers who want vacuuming and mopping handled hands-off, backed by a 2-year warranty, should choose the Shark PowerDetect ThermaCharged RV2920XE, while anyone who mainly wants dependable vacuuming, a lighter price tag and the widest smart-home compatibility can stick with the iRobot Roomba 105X and come out satisfied.

Frequently Asked Questions

Which is better overall: iRobot Roomba 105X or 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 and smart-home integrations, so shoppers who don't need mopping have a strong budget alternative in the Roomba 105X.

What is the biggest structural difference between these two robot vacuums?

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.

Which one has longer battery life?

The Shark PowerDetect ThermaCharged RV2920XE runs longer per charge, rated for around 180 minutes versus 120 minutes for the iRobot Roomba 105X. Both robots support auto-recharge to return to their dock when the battery runs low.

Which one supports more smart-home integrations, and which has the longer warranty?

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.

Who should buy 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 wants the widest smart-home integration support in this pair.

Who should buy the Shark PowerDetect ThermaCharged RV2920XE?

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.
