Roborock Saros 10R vs Shark PowerDetect ThermaCharged RV2920XE

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official Roborock and Shark sites.
2026 verdict
Premium hardware does not automatically win here: the Shark PowerDetect ThermaCharged RV2920XE takes the overall comparison against the pricier Roborock Saros 10R, a flagship robot vacuum, on a lower price, a higher owner rating, a longer warranty and a larger onboard dustbin. The Saros 10R's one real advantage is integrations, since it supports Apple HomeKit, Samsung SmartThings, Home Assistant and Matter alongside Google Home and Alexa, while the Shark model is limited to Google Home and Alexa only. Everywhere else the two are close to even: both use LiDAR navigation with obstacle and cliff detection, multi-room mapping and no-go zones, both mop with auto mop washing and drying at a self-emptying dock, and battery life and connectivity tie between them. The Shark PowerDetect ThermaCharged RV2920XE's two-year warranty also outlasts the Roborock Saros 10R's one-year coverage. Buyers who want the stronger overall value, rating and warranty should choose the Shark PowerDetect ThermaCharged RV2920XE, while those who need deep smart home ecosystem support, especially Apple HomeKit or Matter, should pick the Roborock Saros 10R.
