10,000Pa power and all-in-one docking at a rare low price

Is the roborock Qrevo Series Robot Vacuum Cleaner with Mop (QV 35S) worth buying? Yes — at £399.99, it is a strong buy for mixed-floor homes that want powerful vacuuming, proper mopping, and a hands-off dock, especially because that is the all-time lowest price and 19% below the £493.36 average. The main caveat is that this is still a premium-style robot, so if you only need basic vacuuming or you dislike larger docking stations, there are simpler options.

First impressions: why this model stands out

At first glance, the QV 35S is appealing because it bundles several high-end features into a sub-£400 price point: 10,000Pa HyperForce suction, dual anti-tangle brushes, dual liftable spinning mops, PreciSense LiDAR mapping, Reactive Tech obstacle avoidance, and an all-in-one dock that washes, dries, refills, and empties automatically. That combination matters because it reduces the usual friction points of robot ownership: hair wrap, wet mop pads, and frequent dustbin emptying.

The pricing context is especially important. This model is listed at £399.99, down from an RRP of £499.99, with 20% off and 700+ bought last month. Against a recorded average of £493.36 over 41 weeks, the current price sits 18.9% below average and is the lowest ever recorded at £319.99. That does not make it the cheapest robot vacuum on sale, but it does make the feature set far more attractive than its usual pricing suggests.

How good is the 10,000Pa suction in real use?

The headline 10,000Pa suction is one of the strongest reasons to consider this robot. In practical terms, that level of suction is aimed at lifting embedded dust, crumbs, and pet hair from hard floors and carpets more confidently than lower-powered robots, including the 7,000Pa Dreame L20 Ultra and 8,000Pa ECOVACS DEEBOT X2 OMNI listed in the comparison set. It also compares very favourably with the roborock Saros 10, which offers 22,000Pa but costs £899.99 — more than double the QV 35S.

For UK homes, the real benefit is versatility. If you have a mix of laminate, tile, and low-to-medium pile carpet, 10,000Pa should be enough to handle daily debris without needing a second pass as often. The dual anti-tangle brush system also matters here, because suction alone is not enough if long hair wraps around the main brush and reduces cleaning efficiency.

Are the dual anti-tangle brushes useful for pets and hair?

Yes, the dual anti-tangle system is one of the most practical features on the spec sheet. roborock pairs a rubberized floating main brush with a unique arc-shaped side brush, which is designed to reduce hair wrapping and keep maintenance lower than on standard bristle-heavy designs. That is particularly relevant for pet owners and households with long hair, where brush cleaning can become the most annoying part of robot ownership.

This is not the same as being completely hair-proof, and buyers should not expect zero maintenance forever. But compared with older or cheaper robots, the design should reduce the frequency of manual de-tangling. For homes with shedding pets, that is a meaningful quality-of-life improvement, not just a marketing line.

Is the mopping system better than basic drag mops?

The dual liftable spinning mops are a major upgrade over simple cloth pads. They spin up to 200 RPM, which is intended to scrub more effectively and mimic hand-mop results rather than merely wiping dust around. Because the mop module is liftable, the robot can better separate vacuuming and mopping tasks, which is important on carpeted areas or mixed-floor layouts.

The all-in-one dock adds even more value here. It can self-wash and dry the mop, auto-refill the tank, and auto-empty dust, which means the robot is far more autonomous than models that need frequent pad removal and manual cleaning. For busy households, this is the feature set that turns a robot from a gadget into a genuinely useful appliance.

That said, mopping is still best viewed as maintenance cleaning rather than a replacement for a proper manual scrub on heavily stained floors. The 200 RPM spinning pads are a strong system, but no robot mop can fully match a human for dried-on spills, grout lines, or deep kitchen grime.

How does the navigation and obstacle avoidance compare?

The QV 35S uses PreciSense LiDAR navigation and mapping, which scans 360° and creates detailed maps simultaneously. That is the right foundation for reliable room mapping, efficient route planning, and no-go zone support through the app. LiDAR is usually preferred over camera-only navigation because it performs more consistently in low light and tends to produce more stable maps.

Reactive Tech obstacle avoidance, powered by structured light, adds another layer by helping the robot detect and navigate around objects. In everyday use, that should improve its ability to avoid common floor clutter such as shoes, toys, and cables, although no obstacle system is perfect. If your home is frequently littered with small items, you will still get better results by tidying first and setting no-go zones in the app.

Is the app and mapping system good enough for larger homes?

The Roborock app sounds well suited to proper zone-based cleaning because it supports schedules, specific rooms or areas, and temporary cleaning controls. That is important for anyone with a multi-room home, open-plan living space, or areas that need more frequent attention, like kitchens and hallways. LiDAR mapping plus no-go zones is exactly the kind of setup that helps a robot feel smart rather than random.

For larger homes, the all-in-one dock also matters because it reduces the amount of manual intervention needed between runs. The more rooms and floor types you have, the more valuable that automation becomes. If you want a robot to clean while you are out and manage itself for long stretches, this is the type of system that makes sense.

Is the build quality worth the price?

Based on the feature set and price, yes — the build proposition is strong. You are getting a flagship-style combination of suction, anti-tangle brushes, liftable spinning mops, LiDAR, and a multifunction dock for £399.99, which is far below the £899.99 roborock Saros 10 and also undercuts the £1,040.99 Dreame L20 Ultra and £2,220.21 ECOVACS DEEBOT X2 OMNI in the comparison data.

The main warning is physical footprint rather than outright quality. All-in-one docks are convenient, but they take up more space than a simple charging base, so this is not ideal if you are tight on utility-room or hallway space. Buyers should plan where the dock will live before ordering.

How does the roborock QV 35S compare with alternatives?

Against the roborock Saros 10, the QV 35S is dramatically cheaper at £399.99 versus £899.99, while still offering strong 10,000Pa suction, LiDAR, and auto mop washing/drying. The Saros 10 wins on raw suction at 22,000Pa and adds 80°C mop washing, but that premium is hard to justify unless you specifically want top-tier specs and can afford the jump.

Compared with the Dreame L20 Ultra at £1,040.99 and 7,000Pa, the QV 35S looks better value on suction and price. Against the ECOVACS DEEBOT X2 OMNI at £2,220.21 and 8,000Pa, the roborock is in a completely different value bracket. In short, the QV 35S is not the absolute most advanced robot here, but it is the most compelling balance of features and price in this comparison set.

What should buyers watch out for?

The biggest warning is that this is still a premium robot with premium complexity. If you only want a cheap vacuum for a small flat, the dock and feature set may be more than you need. Also, although Reactive Tech obstacle avoidance and LiDAR mapping are strong features, floor clutter can still interrupt a run, so homes with lots of toys, cables, or loose items will need some prep.

Another consideration is noise and maintenance data: the listing does not provide a dB figure or dustbin capacity, so buyers who care about exact acoustic performance or onboard bin size will need to check further before purchasing. That lack of transparency is a drawback compared with products that publish more complete specs.

Is it good value for money?

Yes, especially at £399.99. The current price is 20% off the £499.99 RRP, 18.9% below the £493.36 average, and the all-time lowest recorded price is £319.99. With a 4.4/5 rating from 3,519 reviews and 700+ bought last month, the market response suggests this is a well-liked model that is priced more aggressively than usual.

The value case is strongest for homes that want one machine to handle vacuuming and mopping with minimal day-to-day effort. If you will use the dock, app mapping, and anti-tangle system regularly, the cost is easier to justify than on a simpler robot.

Final take

The roborock QV 35S is a well-judged buy for homes that want strong suction, effective mopping, and a genuinely automated dock without paying flagship prices. Its best strengths are the 10,000Pa suction, dual anti-tangle brushes, dual spinning mops, and LiDAR-based mapping, all backed by a very attractive current price.

The main downside is that it is still a sizeable, feature-heavy robot, so it is not the right pick for buyers who want the smallest or simplest machine. But for pet owners, mixed-floor homes, and anyone who wants less hands-on maintenance, it is one of the more convincing value plays at £399.99.
