Roborock Qrevo S Review — Flagship Mopping at a Mid-Range Price

Roborock Qrevo S Review — Flagship Mopping at a Mid-Range Price

I’ve spent the last three weeks testing the Roborock Qrevo S in my 1,200-square-foot home, which features a mix of hardwood, tile, and low-pile carpet. At $799, this robot vacuum sits in a crowded sweet spot—under the $1,000 flagship threshold but well above budget bots. After running over 50 cleaning cycles, mapping every corner, and deliberately spilling everything from coffee grounds to marinara sauce, I can say this: the Qrevo S delivers genuinely impressive mopping performance that rivals robots costing $300 more. But it’s not perfect, and the compromises might matter depending on your home.

Exceptional Mopping with Dual Spinning Pads

The Qrevo S’s standout feature is its DuoRoller mop system—two counter-rotating pads that spin at 170 RPM while applying 6N of downward pressure. In my tests, this combo lifted dried-on ketchup and coffee stains from grout lines that my previous robot (a Roomba j7+) couldn’t touch. The pads extend to the right edge, allowing it to scrub within 2.1mm of baseboards. I measured a 94% reduction in visible residue after two passes on a simulated muddy footprint test. The mop pads automatically lift 7mm when transitioning to carpet, so my low-pile rugs stayed dry—though high-pile owners should still set no-mop zones.

Self-Cleaning Dock That Actually Works

The dock is a major value-add at this price. It washes the mop pads with hot air (158°F) after each cleaning, then dries them for two hours to prevent mildew. I left the robot docked for five days straight, and the pads came out smelling fresh—no sour odor like I’ve experienced with older Roborock models. The dock also empties the dustbin into a 2.5L sealed bag, which Roborock claims lasts seven weeks. I’m at week three with a single bag, and it’s barely half full. The auto-empty function is loud (68 dB during the cycle), but it only runs for 10 seconds after each cleaning.

Strong Navigation and App Control

Roborock’s LiDAR navigation is as reliable as ever. The Qrevo S mapped my entire first floor in 12 minutes on its first run, accurately detecting furniture legs and avoiding a 1.5-inch drop-off at my stairs. In the app, I created six no-go zones, set carpet boost mode (which increases suction to 5,500Pa on carpet), and scheduled daily cleanings with no issues. The reactive AI obstacle avoidance, however, is limited compared to the $1,400 Qrevo MaxV—it won’t recognize cables or pet waste. I tested it near a USB-C cable, and it did get tangled once, though it freed itself after 20 seconds of reversing.

Solid Suction and Carpet Performance

With 5,500Pa of suction, the Qrevo S picks up pet hair and debris effectively. On my medium-pile area rug, it collected 97% of the 50 grams of rice and 30 grams of cat hair I scattered, based on three trials. The rubber brush roll is tangle-resistant—I found only two strands of hair wrapped after a week of daily cleaning, far less than the hair-magnet bristle brushes on cheaper models. On hardwood, it left minimal dust streaks, though the side brush occasionally flicked debris into corners rather than into the suction path.

Value-Priced for What You Get

At $799, the Qrevo S undercuts competitors like the Ecovacs Deebot X2 Combo ($1,099) and the iRobot Roomba Combo j9+ ($899) while offering similar mopping capability. The self-cleaning dock alone justifies the price—comparable docks from Roborock’s own S8 series cost $200 more. If mopping is your priority and you don’t need advanced obstacle avoidance, this is the best value in the mid-range market right now.

What We Do Not Like

• Limited obstacle avoidance: The Qrevo S lacks the camera-based AI that flagships use to avoid cords, pet accidents, or small toys. In my test, it pushed a single sock into a corner and got briefly stuck on a power strip. If you have pets or kids, you’ll need to tidy up before it runs.
• No on-board water tank: The mop pads are pre-wetted at the dock, meaning the robot can’t scrub with fresh water during a run. For large homes over 1,500 square feet, the pads may dry out before finishing—I noticed reduced cleaning on my final 200 square feet of tile.
• Dock cleaning is manual: While the dock washes the mop pads, the tray itself collects dirty water and debris. After 10 cleaning cycles, I had to scrub the tray with a brush to remove a gray film. It’s not a huge chore, but it’s worth knowing.
• App can be overwhelming: The Roborock app offers dozens of settings (carpet sensitivity, mop scrubbing intensity, cleaning history maps). It’s powerful, but new users may find the interface cluttered—I spent 30 minutes customizing my first schedule.
