How loud is the QV 35A and its dock?

Noise is the most common owner gripe: the robot is audible but tolerable on lower suction, while the dock's auto-empty cycle is a brief jet-engine roar. Most owners schedule cleans for work hours and accept the few seconds of dock noise as the price of not emptying a bin.

Does it handle pet hair without tangling?

The main anti-tangle roller genuinely works - cat and medium-length hair that wrapped older brushes passes through. Hair does still accumulate at the brush end caps and occasionally clogs the auto-empty port in heavy-shedding homes, so plan on a quick weekly end-cap check rather than zero maintenance.

Can it mop and vacuum in the same run if I have carpet?

Yes for low-pile - carpet detection lifts the mops 10 mm and owners confirm rugs stay dry. Medium and thick pile is where it falls short; owners with plusher carpet report damp edges and either run vacuum-only passes or set no-mop zones for carpeted rooms.

What ongoing maintenance and costs should I expect?

Dust bags every 6-8 weeks, plus periodic brushes, filters, and mop pads - all cheap and widely available third-party, which owners cite as a Roborock advantage. Add a monthly rinse of the dock's wash tray and mop pads, since the cold-water wash alone lets grease and odor build over time.

Is dock flooding something to worry about?

A small number of early owners reported water on the floor around the dock, and the cause was almost always an improperly seated water tank or a damaged gasket rather than a design flaw. Seat both tanks until they click, inspect the gaskets when the unit arrives, and run the first mop cycle somewhere you can watch it.

QV 35A or Dreame L10s Ultra Gen 2 - which should I buy?

The QV 35A wins on price (~$380 vs ~$440), app maturity, and cheap parts; the Dreame counters with hot-water mop washing, heated pad drying, higher suction, and an extending mop that reaches edges and under toe-kicks. Owners who mop greasy kitchens daily lean Dreame; owners who mostly vacuum with light mopping call the Roborock the better value.

Roborock QV 35A

Name: Roborock QV 35A
Brand: Roborock
Price: 380 USD
Availability: InStock

The QV 35A is Roborock's answer for people who want the full self-maintaining experience — auto-empty, mop washing, tank refills, mop drying — without paying flagship money, and at its regular ~$380 sale price it's one of the best value all-in-one robots you can buy. Underneath it's an upgraded Qrevo S: 8,000 Pa suction, PreciSense LiDAR mapping, dual spinning mops at 200 RPM, and a 10 mm mop lift when it detects carpet. Owners consistently praise it on hard floors, where it handles everything from fine dust to cereal in one pass, and the anti-tangle brush setup does what it promises with pet hair. The corners Roborock cut to hit the price are specific and worth knowing: the dock washes mops with cold water and dries them with room-temperature air (so mops take longer to dry and can get musty if you don't check them), obstacle avoidance is sensor-based rather than camera AI, meaning phone cables and socks can still get eaten, and 8,000 Pa is mid-pack for deep carpet cleaning in 2026. The 10 mm mop lift also isn't enough for plush carpet — plan on keeping mops off if most of your home is thick pile. For mostly-hard-floor homes it's the smart-money pick in Roborock's lineup.

Owner Insights(105 discussions)

The QV 35A is the robot that finally made the full self-maintaining experience - auto-empty, mop washing, refilling, drying - a sub-$400 purchase, and owners have responded with some of the most lopsidedly positive sentiment in the midrange. It's effectively an upgraded Qrevo S: 8,000 Pa suction, PreciSense LiDAR, dual 200 RPM spinning mops, and a dock that handles everything but the dust bag. The recurring owner refrain is that it bought back their evenings; several report going weeks without touching it.

Day to day, the strengths are hard floors and mixed pet homes. The spinning mops apply real pressure and pick up sticky spots older Roborocks smeared, the anti-tangle brush keeps cat hair off the roller (though end caps still need a weekly check), and mapping is quick and dependable across multiple floors. The trade-offs are noise - both robot and dock are loud enough that owners schedule around it - a cold-water-only mop wash that wants an occasional hand rinse to stay fresh, and a 10 mm mop lift that's fine for low-pile but leaves damp edges on thicker carpet. Early dock-flooding reports trace to unseated tanks rather than systemic defects, and app hiccups are occasional rather than chronic.

Buy it if you want maximum hands-off cleaning per dollar on mostly hard floors with rugs. At ~$380 it undercuts the Dreame L10s Ultra Gen 2 (~$440), which counters with hot-water pad washing, heated drying, and an extending mop for edges - the strongest alternative if greasy-kitchen mopping is your priority. The Ecovacs T50 Max Pro Omni (~$450) adds camera obstacle avoidance for cluttered floors, but Roborock's app polish and cheap parts keep the QV 35A the default owner recommendation at this price.

Pros

+Owner sentiment is overwhelmingly positive - in aggregated owner discussions roughly 90 of 105 reviews are positive, with several four-month owners saying they're buying a second unit for another floor
+The mop actually scrubs: dual spinning pads apply real downward pressure at 200 RPM, and long-term reviewers confirm it lifts sticky spots and light stains that older drag-a-damp-cloth Roborocks smeared around
+The dock is genuinely self-maintaining - auto-empty, mop washing, tank refills, and pad drying all work as advertised, and six-month owners describe touching the robot only to swap the dust bag
+The anti-tangle brush earns specific praise from cat households - hair that killed older brushrolls doesn't wrap the main roller
+PreciSense LiDAR mapping is fast and accurate, with reliable multi-floor maps and tidy row-by-row coverage even in the dark
+10 mm auto mop-lift plus carpet detection means it vacuums rugs without dragging a wet pad across them
+Replacement parts are cheap and everywhere - owners cite affordable third-party brushes, filters, and bags as a reason they picked Roborock over Ecovacs
+Exceptional value at its common ~$350-380 sale price for a feature set that matched $800+ flagships two years ago

Cons

−It's noisy - both the robot on higher suction and the dock's auto-empty roar draw complaints, so owners schedule runs for when they're out
−Hair still collects at the brush end caps even though the roller itself stays clear - long-haired and multi-pet homes pop the caps and clean them weekly
−A handful of early owners hit dock flooding, traced to incorrectly seated tanks or damaged gaskets - seat the tanks firmly and check the gasket on delivery
−Some pet owners report the auto-empty port clogging with heavy hair loads, needing an occasional manual clear
−Mop washing uses cold water only - no hot-water wash or heated drying at this price, so greasy pads need an occasional hand rinse and the dock can smell if neglected
−The 10 mm mop lift clears low-pile carpet but owners with medium/thick pile report damp carpet edges - true thick-carpet homes should mop and vacuum in separate runs
−Occasional app disconnections and rare firmware-update failures show up in owner reports, though usually resolved by re-pairing
