Roborock Qrevo Edge 2 Flow Review

35,000Pa suction  |  SpiraFlow 2.0 roller mop  |  Retractable LiDAR  |  Warm-air roller drying  |  Auto-empty up to 65 days

Overview

The Roborock Qrevo Edge 2 Flow is a robot vacuum with a roller mop instead of spinning pads. Its SpiraFlow 2.0 roller is 270 mm long, turns at up to 240 RPM with 15N of pressure, and is fed by 16 pressurised clean-water outlets, with a floating scraper. The roller lifts up to 15 mm and a shield drops over it on carpet.

It has 35,000Pa suction, RetractSense full LiDAR with a 100° rear view, and Reactive AI Obstacle Recognition for more than 280 types of object, plus Stain-Target AI that uses the RGB camera to find stains. The dock empties the robot for up to 65 days, refills its water tank and dries the roller and dock base with warm air (Roborock quotes 63°C for its heating module). Roborock says it is not designed for liquid spills over 50 ml. It works with Alexa, Siri, Google Home and Matter.
