Roborock Qrevo S5V vs Roborock Saros 20 Sonic

Full Robot Vacuums comparison in 2026

Updated August 2026
Data from Amazon and official Roborock site.
2026 verdict
Sonic mopping and class-leading suction put the Roborock Saros 20 Sonic ahead of the Roborock Qrevo S5V: it is rated for 36000Pa against the Qrevo S5V's 12000Pa, runs longer at up to 190 minutes, adds 5GHz Wi-Fi and Bluetooth, and reaches Apple HomeKit, Samsung SmartThings and Matter on top of the shared Google Home, Alexa and Home Assistant support. Its sonic-vibrating mop system, which vibrates the pad to work on both carpets and hard floors in one pass, is a mopping approach the Qrevo S5V's standard spinning pads do not use. The Roborock Qrevo S5V keeps a lower price and a slightly larger onboard dustbin, and as the newer, higher-tier Saros 20 Sonic has not yet built up an established track record of owner reviews, buyers weighing the two should factor that in. For proven, budget-friendly automation, the Qrevo S5V remains the safer pick; for the newest suction and mopping technology Roborock offers, the Saros 20 Sonic is the stronger machine.
