Roborock QX Revo Arc review

The QX Revo Arc is the lower-priced tier of Costco's Roborock QX Revo line, and it keeps the hot-water dock that most budget docks drop. Costco's listing specifies 18,500 Pa HyperForce suction with a DuoDivide brush, a dual anti-tangle system on main and side brushes, and a FlexiArm side brush and mop that swing out into corners. The Multifunctional Dock 3.0 washes mops with 167°F hot water, dries them, empties the dust bin and refills the robot's tank. Mops lift 10mm on carpet, and dirt sensors trigger extra cleaning where the floor needs it. Navigation pairs PreciSense LiDAR with Reactive Tech obstacle avoidance. Compared with the QX Revo Ultra 2 it gives up 6,500 Pa of suction and the higher 176°F wash temperature. The dock is a 17.7-inch cube and the robot weighs 8.78 lbs.
