Robot vacuums that also mop have a dirty secret, and it is the mop. Somebody has to rinse it, dry it and put it back, or it starts to smell within days. The better machines now handle that chore in their dock, and Roborock’s 2026 model does it with hot water, at a price that has fallen a long way for Amazon’s Prime Big Deal event: Prime members can get the Roborock Qrevo 2 Pro for $484 instead of $799, with 39% knocked off the list price. White and black are both included.
Hot-Water Mop Washing and an Arm for the Edges
The dock is the heart of the system. After a run, it empties the robot’s dustbin, refills its water tank, washes the mop at 149°F and then dries it with air warmed to 113°F. Heat matters at both stages, since hot water loosens greasy kitchen residue that a cold rinse smears around, and warm drying keeps a damp pad from turning sour. Roborock has also reworked the tray under the mop, adding a soaking mode to make the dock itself easier to keep clean.
Edges are the other weak spot of round robots, which tend to leave a dry strip along every baseboard. The Qrevo 2 Pro has an arm, called FlexiArm, that pushes the mop outward to within 1.85 millimeters of the wall. The side brush is designed to dig into corners too, with up to 30% more corner coverage according to Roborock. I’d treat that last figure as marketing arithmetic, but the principle is sound, and it shows most in kitchens, where crumbs gather under the cabinet overhang.
For vacuuming, suction is rated at 20,000Pa and increases automatically when the robot rolls onto carpet. Hair is handled by what Roborock calls a Dual Zero-Tangle System, an anti-tangle side brush paired with a main brush named DuoDivide, meant to lift long hair and pet fur without letting it wrap. Mixed floors get specific treatment: the robot vacuums carpets before it mops, lifts the mopping module by up to 15 millimeters, and can leave the mop behind altogether when needed. Rugs and low-pile carpet are the stated targets.
Navigation relies on obstacle avoidance that reacts to everyday objects, on fast mapping and on a 3D map in the app for setting rooms and zones. Roborock’s SmartPlan 3.0 adjusts the cleaning to floor types and past runs, and the noise level is given as 54dB, quiet enough to run during a video call in the next room or while a baby naps down the hall. Two caveats before ordering. The robot connects to 2.4GHz Wi-Fi only. And while the dock automates a lot, I would still expect to fill its clean water and empty the dirty water by hand, as the listing mentions no plumbing connection.
Prime membership is required: the Roborock Qrevo 2 Pro costs $484 on Amazon against a list price of $799, in white or black, as a Prime Big Deal. Versions labeled “Set” are listed at $584 on the same page, and returns are free.
