It rates 36,000 Pa against 12,000 Pa, runs on both 2.4 GHz and 5 GHz Wi-Fi, and reaches Matter, Apple Home, SmartThings and Home Assistant where the Roborock Qrevo S5V stays on 2.4 GHz with Alexa, Google Home and Home Assistant.

What the differences mean

Suction

36,000 Pa against 12,000 Pa. The Roborock Saros 20 is in a different class on carpet and embedded pet hair, and even owners of the Roborock Qrevo S5V note it needs higher settings for heavy shedding.

Wi-Fi bands

The Roborock Saros 20 is the only one of the two rated for both 2.4 GHz and 5 GHz Wi-Fi. The Roborock Qrevo S5V is 2.4 GHz only, which adds a step on combined dual-band routers.

Smart home support

The Roborock Saros 20 supports Matter, bringing Apple Home and SmartThings alongside Alexa, Google Home and Home Assistant. The Roborock Qrevo S5V covers Alexa, Google Home and Home Assistant only.

Mop and detergent

The Roborock Saros 20 uses dual spinning mops, washes them with 212 F hot water and dispenses detergent automatically. The Roborock Qrevo S5V washes, dries and lifts its pads but doses detergent by hand.

Bins

The Roborock Qrevo S5V wins on capacity: 325 ml onboard and a 2.7 L dock bin against 259 ml and 2.5 L for the Roborock Saros 20. The difference is small, but it means slightly fewer trips.

What owners say

Roborock owners on both sides of this pair describe the same easy routine and a few shared grumbles. Roborock Qrevo S5V owners praise strong suction and anti-tangle brushes for pet hair, faster cleaning than the robots they replaced and quiet overnight runs; a vocal minority find the app's mapping and room editing rough and limited, and multi-floor use annoying because the dock must move with the robot. Roborock Saros 20 owners go further, calling it a true set-and-forget machine: 36,000 Pa that pulls dust and pet hair from hard-floor gaps, ultra-slim clearance under furniture, quiet mapping that splits rooms on its own and obstacle avoidance that steers around cables and pets. Their complaints are the flagship price, the mop solution that is not in the box, occasional threshold trouble, and a few units that arrived faulty.

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.
