Roborock Qrevo S5V Review: A $899.99 Mop-Washing Dock Priced Against Roborock's Own Sale

What $899.99 buys on the robot

Roborock rates the Qrevo S5V at 12,000 Pa, a figure the page attributes to the company's own internal testing in Max+ mode with a full battery under IEC 62885-2:2021/5.11. The same page lists PreciSense LiDAR mapping for up to four floors, Reactive Tech structured-light obstacle avoidance, dual spinning mops at up to 200 RPM with a 10 mm lift, and an obstacle-crossing rating of 2 cm. The manual lists the pack as 14.4 V and 5200 mAh, which is 14.4 x 5.2 = 74.9 Wh, and the robot as a 3.80-inch-tall, 13.78 x 13.9-inch disc.

Hair handling is where Roborock's own wording splits. The page body says Triple Anti-Tangle System and describes a DuoDivide main brush with two parallel bristle rollers; the same page's JSON-LD and social description say Dual Anti-tangle system, its Key Features list says All-Rubber Brush, and the brand's Amazon listing says Dual Zero-Tangle and a single rubberized floating brush. The SGS certificate number is printed for the 0% tangling claim. Treat the brush count and construction as unresolved rather than as a spec you can rely on.

The dock's capacity, and the year-one parts bill

The dock empties the robot into a 2.7 L E12-rated bag that the maker page says lasts up to 7 weeks, washes the mop pads and dries them with warm air; it refills the robot's water tank and its base detaches for cleaning. This is an emptying-and-washing dock, but the page claims warm-air drying rather than the hot-water mop washing on Roborock's higher tiers. The brand's Amazon listing for the same model claims a 10-week storage bin and 3,552 sq ft of mopping per tank fill, so the two brand channels disagree on the headline capacity.

The US manual sets the wear rhythm: main brushes cleaned every two weeks and replaced every 6-12 months; side brush cleaned monthly and replaced every 3-6 months; washable filter cleaned every two weeks and replaced every 6-12 months; mop cloths replaced every 1-3 months; dust bags replaced as required. On 2026-10-09 the maker's matching parts were $22.99 for the S5V-compatible main brush, $32.99 for two washable filters, $20.99 for four mop cloths, $15.99 for two side brushes and $25.59 for six dust bags.

One year of those parts runs about $119 to $225: 1-2 main brushes ($22.99-$45.98), one filter two-pack ($32.99), 1-3 mop-cloth packs ($20.99-$62.97), 1-2 side-brush packs ($15.99-$31.98), and one six-bag pack at the Amazon interval or two at the maker's 7-week interval ($25.59-$51.18). Add the $899.99 robot and the first year lands near $1,019 to $1,125 before the $18.99 cleaning solution, whose dilution is not printed on the maker page.

Almost none of that parts list could be ordered direct on 2026-10-09. The dust bags, mop cloths, S5V side brushes, the standard two-pack filter listing and both cleaning solutions showed OutOfStock at Roborock; only the S5V main brush, its $19.99 cover and a points-program filter listing showed available. Staying with maker parts may mean waiting for a restock, and the one-year warranty excludes batteries and every part that must be replaced periodically.

The same money elsewhere in Roborock's store

Roborock's own US store sells the Saros 10R at $899.99 next to a struck $1,599.99 list, with the StarSight 2.0 navigation system and a 10-in-1 dock. The Qrevo CurvX is $799.99 beside a struck $1,499.99 list, rated 22,200 Pa with an AdaptiLift chassis. The Saros 10R also carries a hot-water wash the S5V lacks: its page claims 176°F mop washing. The Qrevo S5V carries no strike-through on its page: its $899.99 is the undiscounted price, while the same money bought the Saros dock and $100 less bought the CurvX.

Below the S5V is the Q10 S5+ with an auto-empty dock at $279.99 in Black against a $549.99 list, rated 10,000 Pa with vibrating mopping rather than mop washing. Cheaper than all of them is Roborock's certified refurbished S5V at $529.99, and the brand's Amazon listing showed a Used - Like New unit at $399.99 and an Amazon Renewed unit at $469.99. On 2026-10-09 a new S5V cost $370 more than the maker's refurbished one.

So the $899.99 has to be justified against the same brand's sale prices, not just against older or cheaper robots. On 2026-10-09 a buyer could pay $899.99 for a new S5V, $529.99 for the maker's refurbished one, the same $899.99 for a discounted Saros 10R, or $799.99 for a CurvX. Against the refurbished unit, the S5V's case is a new machine; against the Saros 10R, which also washes mops and adds hot water at the same price, the S5V wins only once that discount has ended.

When the S5V stops making sense

Skip it if the house has thresholds over 2 cm or stair edges you cannot fence off. The page rates obstacle crossing at 2 cm, and the manual rules out high-pile carpets, says effectiveness can drop on dark carpets, limits use to 4-40 C, and tells you to fence off raised areas rather than trust the sensors. Rooms behind a transition taller than 2 cm stay off its route unless you carry it over.

Skip the S5V when a flagship with a self-cleaning dock already sits in your home. The S5V's rated suction sits below Roborock's current premium ratings and its dock lacks hot-water mop washing, so it is a sideways move rather than an upgrade. And because the comparison turns on a discount, re-check the Saros 10R and Qrevo CurvX pages on the day you buy: a $0 or $100 gap decides which dock you get.

Buy it when the floors are hard or low-pile, the dock can stand flat with the manual's 0.9 m of height, 0.4 m of width and 1.2 m of depth clear, and you want the pads washed and warm-air-dried rather than a hot-water tier. The 2.4 GHz-only Wi-Fi is the other setup condition the page prints.
