It does not use hot water. I know that by the time it starts mopping the last bit of the house the place it started in is already dry. After it mops my house feels very clean, no bad smell at all. And I don’t use the cleaning agent, just water for now.
Roborock QV 35A Robot Vacuum and Mop
The Roborock QV 35A is a 2025 mid-range robot vacuum that bundles full dock automation — auto-empty, mop wash, mop dry, and tank refill — with 8,000Pa HyperForce suction and a rubber anti-tangle brush rated 0% hair tangle. It sits below the Qrevo Curv and S Pro in the lineup but offers the same hands-off maintenance experience at a lower price, making it the entry point into Roborock's full-service ecosystem in Canada.

Leave them on. This vacuum is a great deal compared to some of the other overpriced ones
I’ve dealt with Roborock support / warranty service probably six times (we have multiple robots in our house and office) and they’ve actually been amazingly helpful. They’re quick to respond, they’ll send you a prepaid shopping label to mail your robot to their repair center in Texas, and they have a pretty quick turnaround time getting it evaluated and repaired and sent back.
To me, the sides of the floor against the baseboard are just as clean as the rest of the floor. I have yet to notice a distinct difference of the corners/edges being left dirty or looking different or less clean than the rest.
I will agree with some above comments. It does go thru a bit of water. I adjusted mine to use less water. But honestly Iv had like 6 other brands…. This one is amazing. It doesn’t suck up socks, toys and other junk that i previously had tons of issues with.
Recently purchased the same unit. If left them on so far, and don’t have any complaints. It seems to be cleaned and dried effectively I did notice when it goes over area rug/carpet, the carpet was slightly damp. But not overly concerned.
I have this one sitting in my garage, it pisses me off so much, it's great at mopping etc etc however it uses too damn much water I need to keep replenishing the water tank after 3 days, not ok but when it comes to vacuuming the carpet it's absolutely s*** house as well as any kind of edge cleaning... I bought Qurevo Curve to replace it and it's been a dream ever since, no more dirt and dust along the edges of my home.
Yeah, this is exactly why the Mova p10 pro is untouchable at its regular $450 sale price. For $30 more than this when they’re both on sale you get vastly more features that actually improve cleaning and maintainence. Not just the gimmicky features either.
I leave them on all the time! In your settings there should be options for drying time so the pads don’t get moldy. Make sure those are set to like.. 6hrs. I take mine out and bleach and dry them once a month for a deep clean tho.
First off, if you’re considering getting a robot vacuum/mop, just do it. I don’t know how I ever went without this thing. I tell my husband all the time that this is one of the best purchases I have made. I for one love the Roborock app.
My Roborock leaves streaks on the wooden floor after mopping. The streaks appear where the two mops meet. So, there is a small area that is not cleaned, and this creates the pattern on the floor. I also tried this with my brother’s Roborock, which is the same model. The result was the same.
✅ What Works
- The all-rubber spiral main brush is SGS-certified for 0% hair tangling — owners with dogs and cats consistently report zero maintenance cutting hair out of the brush, the most common complaint about robot vacuums with traditional brushes.
- 45 dB in standard mode is among the quietest at this price tier. Owners working from home and those with noise-sensitive pets note it routinely as a reason they leave it running during the day.
- Full dock automation at a mid-range price point — auto-empty, mop wash, auto-dry, auto-refill — is a recurring reason owners cite for choosing this over cheaper alternatives that require manual dock maintenance.
- 180-minute battery covers larger homes in a single pass without the recharge-and-resume interruptions that frustrate owners of shorter-runtime robots.
⚠️ Worth Knowing
- Dock uses cold-air drying rather than heated air — the Qrevo S Pro and Curv add hot-water mop washing. Owners with heavy kitchen grease note the difference when comparing cleaning effectiveness on greasy floors.
- 2.4GHz Wi-Fi only — a consistent friction point in Reddit threads for owners using mesh networks that default to 5GHz bands.
- Mop arms are fixed and cannot extend past the robot body, leaving a 1–2cm strip along baseboards and table legs unmopped.
Owners who land in the QV 35A's sweet spot — hard floors, medium-pile carpet, pets, preference for hands-off operation — repeatedly describe it as the best value at this tier. The full-automation dock, anti-tangle brush, and quiet motor come up more often than any complaint. The limitations are specific: dark floors, high-pile carpet, and a desire for hot-water mop cleaning are the three conditions owners consistently name as reasons to step up.
