What the differences mean

Runtime

290 minutes for the Roborock Qrevo Curv 2 Pro against 190 for the Roborock Saros 20 Sonic. In a large home the Qrevo is far more likely to finish a full clean without going back to recharge.

Suction

36,000 Pa for the Roborock Saros 20 Sonic against 25,000 Pa for the Roborock Qrevo Curv 2 Pro. This is the biggest gain of the Sonic, and it shows on embedded pet hair and carpet.

Wireless and platforms

The Roborock Saros 20 Sonic joins 2.4 and 5 GHz networks and supports Apple Home, SmartThings and Matter today. The Roborock Qrevo Curv 2 Pro is 2.4 GHz only and lists those three as an upcoming update. Both have Bluetooth and work with Alexa, Google Home and Home Assistant.

Dock detergent

The Roborock Saros 20 Sonic dock dispenses detergent automatically. The Roborock Qrevo Curv 2 Pro dock has no automatic dispenser, so you add the cleaner yourself.

Warranty

2 years for the Roborock Qrevo Curv 2 Pro against 1 year for the Roborock Saros 20 Sonic, on a robot with a wet dock that is expected to last for years.

What owners say

Roborock Qrevo Curv 2 Pro owners say it cleans hard and then looks after itself. They highlight setup and mapping that took a couple of hours, strong suction and mopping on pet hair, a dock that empties, washes and dries the pads and pet extras such as the on-board camera and find-my-pet. Their complaints are practical: no floor cleaner and no spare dust bag in the box, one owner whose lowest furniture was still too low, a light some find bright at night and, for a few, everyday suction that felt less impressive than the headline figure. A short learning curve with maps, zones and cleaning modes is also mentioned.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
