Roborock QV 35A Review 2026: 90% on Carpet, Near the Bottom on Obstacles

Quick Answer: The Roborock QV 35A is an 8,000 Pa LiDAR robot vacuum with two spinning mops and a dock that empties the bin, washes and dries the mop pads, and refills the water tank. Vacuum Wars measured 90% deep-carpet cleaning and about 1,536 sq ft per charge, both well above average, but rated its obstacle avoidance 1.22 of 5 stars and its overall score 2.91 stars. Roborock’s US store listed it at $449.99 on November 4, 2026, $50 more than its own Qrevo S Pro, which adds a hot-water mop wash and warm-air drying. Buy the QV 35A for carpet in a tidy home, and only near $400 or less.

Roborock sells the QV 35A as “upgraded from Qrevo S”, and Vacuum Wars’ Roborock buyer guide calls it the first Q-series robot with dual spinning pads and a mop-washing dock. It also has an awkward neighbor: Roborock currently sells the Qrevo S Pro for less, with more than twice the rated suction and a dock that heats both the wash water and the drying air. The lab data complicates that picture, though, because the QV 35A measured better than the S Pro on almost every vacuum test. This review compares both, using Roborock’s US product pages, Vacuum Wars’ published measurements and Tom’s Guide’s review of the near-identical QV 35S.

Roborock QV 35A by the numbers

• 90% deep-carpet cleaning of embedded sand, per Vacuum Wars. The lab’s recent reviews put the average near 75%, and the Qrevo S5V’s 92% ranked 4th of 150+ robots.
• 1,536 sq ft per charge (estimated by Vacuum Wars) against an average of about 1,015 sq ft, with 1.64 minutes of runtime per 1% of battery.
• 58.7% flattened pet-hair pickup, well below the 82% average quoted on the November 3, 2026 Vacuum Wars leaderboard.
• 0.36 kPa sealed suction and 15 CFM airflow against an 8,000 Pa rating. The averages in Vacuum Wars’ recent reviews are about 0.83 kPa and 16 CFM.
• 1.22 of 5 stars for obstacle avoidance, the same rating as the Qrevo S, and 3.54 stars for navigation.
• Vacuum Wars overall: 2.91 stars, one hundredth below its Best Budget pick (Dreame D20+, 2.92) and well short of the Top 20 cutoff of 3.69.
• $449.99 on Roborock’s US store on November 4, 2026 (compare-at price $649.99), against $399.99 for the black Qrevo S Pro.

Specs come from Roborock’s US product page and FAQ unless marked. Mop lift, bag duration, shipping weight and Wi-Fi band come from Vacuum Wars’ comparison database.

A fair price is $400 or less. At $449.99 it costs more than Roborock’s own better-equipped Qrevo S Pro.

The lab results against the average robot

Vacuum Wars publishes its measurements for the QV 35A (black) in its robot vacuum comparison database. The figures below are its measured results, not Roborock’s spec sheet. Averages are the ones Vacuum Wars quotes in its recent reviews of other robots, because the database page does not list them.

Sources: Vacuum Wars comparison page for the Roborock QV 35A (black), checked November 4, 2026. Averages from Vacuum Wars’ Qrevo S5V and eufy Omni E25 reviews (October 2026) and its November 3, 2026 Top 20 leaderboard.

Two numbers stand out. A 90% carpet score is close to the best Vacuum Wars records; the Roborock Qrevo S5V, at 92%, ranked 4th of more than 150 robots. And 1,536 sq ft per charge is about 50% more than the average, so the QV 35A can clean a large single-floor home without stopping to recharge. The weak spot for pet owners is the 58.7% flattened-hair result. The rubber brush resists tangles, but in this test the QV 35A left behind about two in five hairs that the average robot would have picked up.

Obstacle avoidance: the same weakness as the Qrevo S

Roborock’s Reactive Tech uses a structured-light sensor to see that something is in the robot’s path. Without a camera, it cannot tell a sock from a chair leg or a cable from pet waste. Vacuum Wars gave the QV 35A 1.22 of 5 stars for obstacle avoidance. That is the same rating it gives the Roborock Qrevo S, the robot the QV 35A “upgrades”, and Vacuum Wars described the Qrevo S’s obstacle result as tied for the worst it had recorded.

The navigation itself is fine. LiDAR mapping earned 3.54 stars, and Roborock’s app adds suggested no-go zones for spots where the robot tends to get stuck, along with “add area” and “skip area” for one-off changes. If your floors are clear before each run, the QV 35A will cover them efficiently. If you have a puppy, loose charging cables or toys on the floor, a camera robot such as the Ecovacs Deebot T90 Pro Omni (23 of 24 obstacles avoided at Vacuum Wars) will save you more cleanup than the QV 35A’s carpet score is worth. Our best robot vacuum with obstacle avoidance guide lists the strongest options.

The dock: everything automated, nothing heated

The dock is what separates the QV 35A from Roborock’s cheaper Q7 and Q10 models, which only self-empty or use a charging base. Per Roborock’s US page it:

• empties the robot’s 330 ml bin into a 2.7 L bag, emptying more often when it detects a lot of hair (with auto-empty set to High);
• washes both mop pads in a 3-stage cycle, using scrapers in a removable cleaning tray;
• refills the robot’s built-in water tank, whose flow you set per room in the app;
• dries the pads and the tray with cold air, turning the pads periodically so they dry evenly.

That last point is the main compromise. Roborock’s FAQ says the drying module “supplies cold air”, and Vacuum Wars’ buyer guide says the QV docks “wash the mop pads with cool water and air-dry the pads.” There is also no automatic detergent dosing and no dirty-water sensor. Unheated drying is slower, which matters in humid climates where damp pads can start to smell. You also have to rinse the cleaning tray yourself; Roborock says to “remove and clean the tray regularly.”

Plan for space. Roborock asks for about 2.9 ft of clearance above the dock, 1.3 ft of width and 3.9 ft of depth, on a hard, flat floor against a wall.

QV 35A vs Qrevo S Pro vs Qrevo S: Roborock’s own price problem

Roborock’s US product page for the Qrevo S Pro includes its own “Qrevo S Pro VS. QV 35A” table. The two share the LiDAR, the Reactive Tech sensor, the all-rubber brush, the anti-tangle side brush and the dual spinning mops. The S Pro adds 18,500 Pa of rated suction, a 167°F mop wash and 113°F warm-air drying. On November 4, 2026 Roborock sold the black S Pro for $399.99 and the QV 35A for $449.99.

The measured results tell a different story from the spec sheet.

Sources: Vacuum Wars comparison pages for each model and Roborock’s US store, both checked November 4, 2026. Qrevo S dock details from our Qrevo S review.

The S Pro’s 18,500 Pa rating does not show up on the bench: it measured 0.31 kPa, less than the 8,000 Pa QV 35A. The QV 35A also cleaned more carpet (90% vs 81%), picked up more pet hair (58.7% vs 43%) and avoided obstacles slightly better. The S Pro wins on mopping, by a small margin in the lab and by a clear one on hygiene, because hot water and warm air clean and dry the pads better.

So the choice depends on your floors. Carpet-heavy home: the QV 35A is the better robot, but wait for it to drop to $399.99 or less, because $50 extra for the model with the cheaper dock is hard to justify. Mostly hard floors: buy the Qrevo S Pro while it costs less. Both are weak at obstacle avoidance, so neither suits a cluttered home.

Other robots at the same price

Vacuum Wars’ November 3, 2026 leaderboard puts two much higher-scoring robots within about $100 of the QV 35A:

• Ecovacs Deebot T90 Pro Omni, the lab’s Best Value pick, scored 3.98 and was showing $549.00 (list $799.99). It avoided 23 of 24 obstacles, picked up 100% of flattened pet hair and washes its mop with hot water. For $99 more than the QV 35A, it fixes both of the QV 35A’s weak spots.
• eufy Omni C28, ranked #18 at 3.72, was showing $499.98 (list $799.99). Our Omni C28 review covers its top-10 mopping score and 100% pet-hair result; its obstacle avoidance is only average.

At the bottom end, the lab’s Best Budget pick, the Dreame D20+, scored 2.92, almost the same as the QV 35A’s 2.91, at $278.99. The QV 35A’s extra cost buys the mop-washing dock, not better vacuuming. For more options in this price range, see our best robot vacuum under $500 list.

What Tom’s Guide found on the QV 35S

Tom’s Guide has reviewed the QV 35A’s close sibling. It gave the QV 35S (10,000 Pa, same body and dock) 4 out of 5 in April 2026 and noted that the QV 35A “looks virtually identical” apart from its 8,000 Pa suction. The reviewer reported good obstacle handling in a normal home and mopping that recognized rugs and lifted the pads, but also hair left behind on low-pile carpet and most of the hair and small seeds left on high-pile carpet. Tom’s Guide reported about 55 dB while mopping and 60 dB while vacuuming. Those findings fit the QV 35A’s lab profile: strong on embedded dirt in ordinary carpet, weaker with pet hair. The QV 35S was listed at $549.99 and out of stock on Roborock’s US store on November 4, 2026.

Who should buy the Roborock QV 35A

• Buy it if most of your floors are low- or medium-pile carpet. A 90% deep-clean score is close to the best on record.
• Buy it if you have a large single-floor home. About 1,536 sq ft per charge is roughly 50% above average.
• Buy it if you want a fully automated dock for under $450 and live somewhere dry enough that cold-air drying is not a problem.
• Skip it if your floors have cables, socks, toys or pet accidents. 1.22 stars for obstacle avoidance means it will run into them.
• Skip it if you have a heavy-shedding pet. The 58.7% pet-hair result is well below average.
• Skip it if Roborock’s Qrevo S Pro still costs less and you have mostly hard floors.

No US safety recall is listed for any Roborock robot vacuum: a search of the CPSC recall database for “Roborock” returned no results on November 4, 2026.

The bottom line

The Roborock QV 35A is a carpet specialist in a budget full-dock body. Vacuum Wars measured 90% deep-carpet cleaning and about 1,536 sq ft per charge, both well above average, but rated it 1.22 stars for obstacle avoidance and recorded only 58.7% pet-hair pickup, for 2.91 stars overall. Its dock automates everything but heats nothing. At $449.99 it costs $50 more than Roborock’s own Qrevo S Pro, which has a hot-water dock and wins for hard floors, and $99 less than the Ecovacs T90 Pro Omni, which outscores it everywhere except price. Buy the QV 35A near $400 or less for a tidy, carpeted home. To compare the rest of the lineup, see our best Roborock ranking or our overall best robot vacuum picks.
