Bottom Line
Choose QV 35A for strong vacuum+mop cleaning with a low-effort dock at a budget-leaning price; Skip if you need reliable cable avoidance or fast hot-water/hot-air mop drying.
Best for
Homes with mostly hard floors (and low/medium rugs) that want automated vacuuming plus frequent, hands-off mopping, and are willing to pick up cords or set no-go zones to get the best runs.
Not for
Homes with lots of loose cables, toys, or high-pile carpet hair that need top-tier object avoidance and deep carpet hair pickup, or anyone who wants heated mop washing and fast hot-air drying to minimize odors.
Verdict
The QV 35A pairs accurate lidar mapping with an all-in-one dock that empties, refills, and washes rotating mop pads, so it can keep hard floors consistently tidy with minimal daily effort. Reviews praise the robust Roborock app, straight-line coverage, and the privacy benefit of having no front camera. The tradeoff is that reactive obstacle avoidance still struggles with low cables and tiny clutter, and the dock uses room-temperature washing and drying, so pads can take many hours to dry and odors can develop if the dirty tank is ignored. It makes the most sense when discounted below about $500.
Pros
-
Multiple reviews explicitly note there is no front-facing camera, and one comparison also states no microphone, which can be appealing for privacy-sensitive buyers. The tradeoff is less sophisticated object recognition than camera-based systems.
-
Setup is described as simple: attach the dock base/ramp, fill tanks, scan the QR code, and run quick mapping. A common note is that the robot prefers 2.4 GHz Wi-Fi and docking alignment can take a bit of care.
-
Cliff/drop sensors are repeatedly mentioned and shown as effective at preventing falls near stairs and edges. Reviewers also note the sensors need occasional wiping to stay accurate.
-
Controls are straightforward with physical power/home buttons plus a feature-rich app for room selection, routines, and dock controls. Reviewers also mention adjustable robot voice volume/language and remote-control style driving modes.
-
Fine debris like coffee grounds and small crumbs are reported to be picked up very effectively on hard floors, often with little left after a pass. Reviewers attribute this to strong suction and systematic pathing.
-
Large debris on hard floors (rice, chips, noodles, clumps) is generally handled well, with reviewers commonly seeing most debris removed on the first pass and the rest on a second.
-
The Roborock/Qrevo app experience is repeatedly described as excellent and full-featured, with routines, schedules, room/zone cleaning, no-go zones, and deep control over suction, water, and dock behavior. A few notes include needing 2.4 GHz Wi-Fi during setup and (in one review) manually setting floor types for best results.
-
Build quality impressions are strong for a budget-leaning model, with reviewers calling out neat finishes, a sturdy bumper, and overall fit-and-finish similar to higher-end Roborock units.
-
On hard floors, long hair pickup is generally reported as strong, especially when paired with straight-line cleaning and adjustable settings. Some hair can still collect on brushes, but overall pickup is praised.
-
Lidar-based mapping and straight-line pathing are consistently praised for neat, efficient coverage. Reviews mention quick mapping, multi-floor support, and accurate 3D-style maps, with predictable perimeter-then-grid cleaning behavior.
-
Ease of use is a major positive: reviewers call it convenient to run, easy to set schedules and routines, and largely hands-off thanks to the dock’s washing and emptying. The biggest usability friction points are cable prep and keeping tanks/tray clean for best hygiene.
-
Mop pads can lift roughly 10 mm when carpet is detected, helping prevent wet rugs. This lift behavior is mentioned across multiple reviews and is treated as reliable and useful.
-
The liquid system earns praise for an onboard tank, frequent auto-refills at the dock, and a wide range of adjustable water flow levels. Tradeoffs called out include room-temperature water (no heating) and limited intelligence for automatically re-mopping heavily soiled areas.
-
Dock operations are generally reported as not super loud, with mop washing and bin emptying described as reasonable and the drying fan often called very quiet.
-
Threshold handling is a standout: reviews report it can climb around half-inch to three-quarter-inch transitions and generally adapts well to small bumps. Wheels and a floating brush/chassis design help maintain contact on uneven surfaces.
-
Filtration is viewed positively: the filter is washable and the docked system is described as good at keeping dust contained, with one review citing SGS certification for high particle capture (e.g., pollen).
-
During auto-emptying, one review highlights reduced dust puffback thanks to a more sealed, multi-layer bag/door setup. Overall, airflow-related mess during emptying is described as minimal.
-
Carpet and rug handling is a strength: the robot can detect carpet, lift the mops about 10 mm, and adjust behavior (including carpet boost and vacuum-first options). Some users still prefer to avoid carpets during mopping for best results.
-
Overall sentiment is strongly positive for the price, especially around mapping accuracy, automation via the dock, and solid vacuum+mop performance. Most negatives are framed as expected tradeoffs in a cheaper model (no heated drying, limited edge reach, cable avoidance limits).
-
The dock’s mop washing is repeatedly praised, including agitation in the tray and the ability to remove/rinse the base for easier hygiene. Auto-emptying and tank refills add to the hands-off ownership experience.
-
Docking, auto-empty, and auto-refill functions are described as reliable in normal use and contribute to the set-and-forget experience. A few notes mention docking alignment can be a little finicky, but overall automation works as intended.
-
The clean/dirty tank setup is considered convenient and easy to remove, and the robot also carries an onboard water tank that gets refilled at the dock. Multiple reviews warn the dirty tank can smell if left too long, so frequent emptying/rinsing helps.
-
Value is a consistent theme: most reviews frame the QV 35A as a standout buy when priced under about $500 (and especially when discounted further). Several caution it is less compelling at higher prices because it lacks premium extras like heated wash/dry and edge-extension hardware.
-
Auto-emptying into a dock bag minimizes hands-on mess and reduces how often the onboard bin needs attention. Reviewers appreciate the cleaner emptying experience versus manual dumping.
-
Comparisons in the reviews often favor the QV 35A on value: several reviewers say it matches or even beats more expensive siblings in basic navigation and cleaning. The main gaps versus pricier models are extra sensors, AI cameras, heated wash/dry, and edge-extending hardware.
-
Rotating pads and controlled water delivery allow the QV 35A to scrub many dried or sticky spots (e.g., coffee residue, syrup-like spills) surprisingly well. Reviews still emphasize that very large messes may require multiple passes or manual pre-cleaning.
-
Firmware updates are managed through the app, with options for checking or enabling auto-updates. Reviewers describe the update process as accessible and, in at least one case, already up to date out of the box.
-
Across reviews, 8,000 Pa suction is described as strong for the price and effective for day-to-day pickup on hard floors and rugs, with debris often cleared in one or two passes. Multiple reviewers say it performs similarly to pricier Roborock models in core vacuuming, but it still is not a full replacement for an upright on heavy carpet.
-
The app provides maintenance tracking for parts like the filter (remaining life and reminders). Reviewers note you may need to reset timers after cleaning to keep reminders accurate.
-
Reviewers highlight pet-friendly touches like pet-area deep cleaning settings, strong day-to-day hair control, and solid mopping for muddy paw prints. Heavy carpet hair can still take extra passes and occasional brush cleaning.
-
Unboxing coverage notes the essentials are included (robot, dock, ramp/base pieces, mop pads), with setup-focused extras rather than a large accessory bundle.
-
A child lock is available in the settings, adding peace of mind for households where kids might press buttons or start a run unintentionally.
-
One setup review specifies the dock power cord is about 6 ft, which is generally sufficient for flexible placement near an outlet.
-
Dual spinning mops (around 200 RPM) deliver strong scrubbing for routine grime and many stains, with adjustable water flow and the benefit of an onboard tank. For big messes, some smearing can occur and the robot may need extra passes or a manual assist because it lacks advanced dirt-detection re-mop logic.
-
The robot bin and dock bag system are considered practical: one review calls out a larger 330 ml onboard bin, while others note bag replacement roughly every 2 to 3 months depending on use (often longer in cleaner homes).
-
The robot reliably returns to dock to charge and includes app options like off-peak charging to reduce energy costs. Reviews do not provide measured runtime numbers, but charging behavior is described as standard and dependable.
-
Ongoing maintenance is described as manageable but real: periodic filter washing, sensor wiping, tray rinsing, and dirty tank cleaning are recurring tasks. The removable dock base/tray and clear in-app maintenance timers make upkeep easier.
-
For general carpet pickup (especially larger debris), results are described as solid, often improving with a second pass or deep-clean pattern. Hair on carpet is the more common weak point rather than food/debris pickup.
-
The dock includes basic cord storage/management, helping keep the power cord tidy behind the station.
-
Reactive tech obstacle avoidance is generally good for larger items (furniture, many toys) and can mark obstacles on the map, with adjustable sensitivity. Multiple reviews agree it struggles most with low, thin cables/wires and very small clutter, where bumps or run-overs can happen.
-
Under-furniture access is good for typical clearances, with multiple reviews showing it can clean beneath some furniture. Its height around 3.8 inches means very low furniture may remain out of reach.
-
Customer support is described as friendly and ultimately helpful, but slower than ideal, with back-and-forth email and multi-week resolution mentioned. Day-to-day reliability is generally praised, with the usual caveats around occasional snags and maintenance.
-
Corner performance is described as acceptable but not class-leading. Several reviews point to the lack of extendable brushes/pads as the limiting factor, even though the robot’s perimeter passes still catch a lot along edges.
-
Innovation is framed as value-focused rather than cutting-edge: reviewers highlight that it skips premium extras like AI camera object recognition, mechanical arms, hot-water washing, hot-air drying, and extendable edge tools. The upside is getting many flagship-like fundamentals at a lower price.
-
The robot generally navigates efficiently, but low cables/wires and certain tight areas can still cause issues. Reviewers recommend picking up clutter and using no-go zones, and the app may flag problem spots over time.
-
At roughly 3.8 inches tall, the robot is relatively low-profile, but not ultra-slim. Reviewers advise checking furniture clearance if under-sofa cleaning is a priority.
-
The all-in-one dock adds a noticeable footprint and needs vertical clearance to remove tanks; one setup walkthrough recommends allowing substantial space above the dock for tank access.
-
Edge cleaning is described as decent in normal perimeter runs, but multiple reviews note it lacks extendable side brushes or mop pads, so edge-to-edge results and tight baseboards can lag behind higher-end models.
-
The anti-tangle design (rubber main brush and redesigned side brush) reduces snarls and makes maintenance easier, but it does not eliminate hair wrap entirely. At least one hands-on test still found noticeable wrap with very long hair.
-
Reviews caution that, like most robot vacuums, it is best for maintenance cleaning rather than heavy-duty deep cleaning. Homes with lots of thick carpet or extreme debris still benefit from occasional full-size vacuuming.
-
A few tests show smearing can happen on muddy prints or when pads carry dirty liquid before they are washed. Users note that extra passes, better floor-direction settings, or more frequent pad washing can reduce residue.
-
Drying is a known compromise: the dock uses room-temperature air rather than hot air, so pad drying can take many hours (often cited in the 4–8 hour range, with longer options available). This is acceptable to some reviewers but a dealbreaker for others wanting faster hygiene.
Cons
-
Hair pickup on carpet is repeatedly described as the biggest cleaning weakness, with rubber brushes struggling to lift embedded hair. Deep-clean patterns help, but some hair may remain compared with bristle-heavy rollers.
-
Odor risk centers on the dirty water tank and slow pad drying: several reviewers recommend emptying and rinsing the dirty tank frequently (some even add disinfectant) to prevent foul smells. Neglecting this step is repeatedly called out as a downside.
FAQ
Does it reliably avoid cords and small clutter?
Reviews say reactive obstacle avoidance is good for larger objects and many toys, but low cables and thin clutter are still a common failure point. Plan to pick up cords or use no-go zones for trouble areas.
Does it have a camera, and what does that mean for privacy?
Multiple reviews note there is no front-facing camera (and one comparison also mentions no microphone), which some buyers prefer for privacy. The downside is less advanced object recognition than camera-based robots.
How good is the mopping on dried or sticky messes?
The dual spinning pads can scrub many dried stains (like coffee residue) and sticky spills, especially with higher water flow or multiple passes. Very heavy messes can smear until the pads are washed, so an extra pass may be needed.
How long do the mop pads take to dry at the dock?
The dock uses room-temperature air rather than hot air, and reviewers commonly cite several hours for pad drying, with selectable durations (often 6 to 12 hours). Faster drying is a key difference versus more expensive warm-air docks.
How often do you replace the dust bag and empty the tanks?
Several reviews suggest replacing the dock dust bag about every 2 to 3 months in typical use (sooner with lots of pet hair). The dirty water tank should be emptied and rinsed regularly to prevent odors.
