iRobot Roomba 505X vs Shark PowerDetect ThermaCharged RV2920XE

Smart-home reach and price side with the iRobot Roomba 505X here: it connects over both 2.4GHz and 5GHz WiFi and pairs with Apple HomeKit, Samsung SmartThings, Home Assistant and Matter on top of Google Home and Alexa, none of which the Shark PowerDetect ThermaCharged RV2920XE supports beyond Home Assistant. That breadth, plus a lower price, is enough to give the iRobot Roomba 505X the overall edge, even though the Shark PowerDetect ThermaCharged RV2920XE wins on paper in three places that matter day to day: a higher owner rating, a longer 2-year warranty, and roughly 180 minutes of runtime against 120. The Shark's real differentiator is its 185F heated mop-pad wash, which owners consistently praise for wood and tile floors, though the same owners report some units struggling to dock reliably or losing water flow within months. Both robots vacuum, mop, self-empty and wash and dry their mop pads automatically, and both use the same LiDAR navigation with multi-room mapping and no-go zones. Buyers who want the broadest smart-home support and a lower price should choose the iRobot Roomba 505X; buyers chasing the hottest mop wash and a longer runtime, and willing to accept some risk of docking or water issues, may still prefer the Shark PowerDetect ThermaCharged RV2920XE.
