What the differences mean

Detergent

The Roborock Saros 10R dock doses cleaning solution by itself. The Shark PowerDetect ThermaCharged RV2920XE dock washes the mop with heated water but any detergent is added by hand.

Smart home

The Roborock Saros 10R supports Matter, Apple Home and SmartThings as well as Alexa, Google Home and Home Assistant. The Shark PowerDetect ThermaCharged RV2920XE covers Alexa, Google Home and Home Assistant.

Warranty

Two years on the Shark PowerDetect ThermaCharged RV2920XE, one year on the Roborock Saros 10R.

Suction and height

The Roborock Saros 10R is rated at 22000 Pa and stands 79.8 mm tall. Shark publishes neither figure for the Shark PowerDetect ThermaCharged RV2920XE, so the two cannot be compared on paper.

What owners say

Owners of both robots praise quiet running, accurate mapping and strong mopping on hard floors. Roborock Saros 10R owners, many of them former Roomba users, single out solid-state LiDAR that gets close to furniture without scraping it, a slim riser chassis that climbs thresholds and brushes that stay free of long hair, while their complaints are no cleaning solution in the box, higher water use and silicone brushes that struggle on thick rugs. Shark PowerDetect ThermaCharged RV2920XE owners like whole-home coverage on one charge and describe its mopping on wood and tile as outstanding, but report failures to leave or return to the dock, false obstruction alerts from the mop self-cleaning and water dispensing that stops on some units.
