Roborock QV 35A review

The Roborock QV 35A pairs a vacuum-mop with two spinning mop pads and an all-in-one dock that empties dust, washes the pads, dries them with cold air and refills the robot’s onboard water tank. That makes it a different choice from a dust-only auto-empty robot, and from a roller-mop model such as Roborock’s Qrevo Curv 2 Flow. The US listing carries black and white finish SKUs under one QV 35A product page; its manual identifies the robot as RRE0PEE and the Empty Wash Fill Dock as EWFD36LRR. The product page calls it “upgraded from Qrevo S,” but that marketing phrase is not a substitute for its own model and dock identity.

A dock that takes over several chores

In addition to dust collection, Roborock says it washes the two mop modules, dries the cloths and cleaning tray with cold air, and refills the robot’s electronic water tank from the removable clean-water reservoir. The robot can return to wash and refill during a run; the manual says to start cleaning from the dock and leave the dock in place if you want those automatic returns. It is not a fixed-plumbing installation, but it still means filling clean water, carrying out dirty water, replacing a disposable dust bag and periodically removing and rinsing the cleaning tray. You trade less hands-on pad washing between runs for a more substantial station and more water-related upkeep than a dust-only base.

Roborock describes the pads as rotating at up to 200 rpm under an internal test using the extreme water-flow setting; that condition is not a measured floor-cleaning result. Roborock also lists up to 8,000 Pa suction. Neither figure tells you how well this particular robot picks up hair, grit or dried spots in your rooms. The cleaner distinction for shopping is the hardware and routine: two liftable spinning pads, a robot-fed water tank and a wash/refill dock.

Match the route before buying

Roborock lists the robot at 13.78 by 13.9 inches and 3.8 inches high. That is lower than the 4.69-inch body listed for the Qrevo Curv 2 Flow, but a nominal height is not a promise that the robot will pass a sagging sofa skirt, rug fringe or uneven threshold. Measure the narrowest part of the actual route and leave room rather than using the published height as a guaranteed fit. The product page also claims up to a 2 cm threshold crossing. Treat this as a maximum maker claim—not proof that the robot will climb your particular doorway strip or a combination of rug and threshold.

The manual is more important than a general carpet feature list: it says not to use the machine on high-pile carpet and warns that effectiveness may be reduced on dark carpets. Roborock says the mop mounts retract for carpet cleaning and offers carpet strategies in the app, but that does not override the manual’s high-pile restriction. If your essential route depends on thick pile, do not shortlist this model on the strength of carpet detection or mop lift alone. Its page describes Reactive Tech structured-light avoidance and PreciSense LiDAR mapping; clear cords and small fragile items before unattended runs.

Plan its water and network routine

The dock uses removable tanks, so it avoids a dedicated supply and drain but needs a reachable location, a nearby outlet and regular clean/dirty-water handling. The manual asks for at least 0.4 m of width, 1.2 m in front and 0.9 m in height around the dock, with a hard, level floor and good Wi-Fi coverage. Those are setup clearances, not the dock’s physical dimensions. Roborock’s current US page says the product supports 2.4 GHz Wi-Fi only; a home that can offer only 5 GHz is a poor fit for app setup. The app holds its water settings and schedules.

Do not mistake cold-air drying for a heated floor-mopping system. The manual says to fill the clean-water tank with tap water and only cold water, and the page does not state a mop-wash-water temperature. If warm water in the robot’s mop cycle or a minimum heated dock-wash temperature is essential, this model is not confirmed to meet that requirement. The manual also says not to operate it if any liquid or sticky substance is on the floor. This is a routine maintenance mop, not a wet-spill pickup machine.

What ownership still asks of you

Before the first mop run, the manual says to vacuum the floors at least three times to reduce dirt building up on the cloths. Fill the clean dock tank with cold tap water; use only Roborock-recommended solution if using a cleaning additive. Keep the mop cloths clean and air-dry them, inspect the pads and tray, and empty the dirty-water tank when needed. The tray can be removed and rinsed. The station does not make upkeep disappear: the manual also calls for periodic brush, filter, dustbin, sensor and wheel care, and the dust bag still needs replacement. The washable filter and bin must dry thoroughly after rinsing, with a 24-hour drying instruction in the manual.

Who should compare it with something else?

Choose the QV 35A when you want the dock to take over mop washing and dust emptying, prefer twin spinning pads to a flat cloth or roller, have a 2.4 GHz network and can maintain removable water tanks. Compare the Q7 M5+ if a simpler flat cloth and dust-only auto-empty dock are enough; it leaves the cloth and robot tank to you. Compare the Qrevo Curv 2 Flow if a continuously refreshed roller is the feature you want, but check its taller body and distinct manual cautions. These are different systems, not a tested ranking. Read the exact QV 35A US product page and the linked QV/QR Series FCC user manual for current setup and compatibility instructions before choosing a location.
