The Roborock Qrevo S is an upper mid-range robot vacuum that comes bundled with a multifunction dock. This dock not only empties its dustbin but also refills its water tank for mopping and washes and dries its mopping pads. This particular model is essentially a slightly upgraded version of the Roborock Qrevo. It has a marginally more powerful suction motor, a mop lift system that can raise its mop pads higher, and an improved base plate design for its multifunction dock to minimize leaks.
The Roborock Qrevo S is decent for bare floors. It does a great job of clearing away various kinds of debris on this surface type and has a mopping system that's quite effective in clearing away dried-on stains. Its multifunction dock also helps to reduce day-to-day maintenance — you won't have to worry about emptying its dustbin or washing its mopping pads manually. Once it's mapped out your home, it also provides a very hands-off ownership experience, with a plethora of scheduling and mapping settings that ensure you won't have to make too many adjustments.

The Roborock Qrevo S is okay for use on low-pile carpets. It delivers alright overall debris-pickup performance. It only does an alright job of actually clearing away debris on this surface type; it's fine for dealing with larger debris but doesn't provide enough power or surface agitation to lift away finer debris that's been pressed deeper into carpet fibers. On the upside, it has a wide variety of carpet-specific cleaning settings and features. Its mop lift system allows it to raise its mopping pads when passing onto carpets or rugs, and it has a deep cleaning setting that forces the vacuum to prioritize dealing with messes on carpets before cleaning anything else. It's bundled with a multifunction dock that empties its dustbin and washes and dries its mop pads. This function removes a lot of tedium from day-to-day maintenance but also incurs its own separate set of maintenance obligations and recurring costs.

The Roborock Qrevo S is an alright option for cleaning high-pile carpets. It can struggle with climbing onto especially plush carpeting, either by getting stuck or by identifying thicker carpets as hazards to be avoided. Even on slightly lower-pile carpets, its debris-pickup performance is nothing special. However, its mop lift system is a handy feature if you frequently have the vacuum run mopping jobs in your home but require it to move over carpeted surfaces to get there first. Compared to the older Roborock Qrevo, the Qrevo S can raise its mopping pads even higher, allowing it to pass over higher-pile rugs and carpets without getting them wet.

The Roborock Qrevo S is a fair choice for pet owners. Pet hair pickup performance is pretty poor on more demanding surfaces, like low-pile carpeting, and the vacuum itself does a terrible job of sealing in fine allergens like pet dander as it cleans. That said, it does have a very effective mopping system, and it will do a good job of scrubbing away any mud or dirt your pet might track in from the outdoors. Its multifunction dock also eliminates the need for you to empty its dustbin or wash its mop pads manually. It also runs pretty quietly, which is great for easily startled pets.

The Roborock Qrevo S is available in two colorways: 'Black' and 'White.' We tested the 'Black' model. For those interested, here's the label.
Let us know in the comments below if you come across another variant of this vacuum.
The Roborock Qrevo S is an upper mid-range robot vacuum. It sits closer to the bottom of Roborock's crowded Qrevo lineup, positioned above the entry-level Roborock Qrevo. It offers a few minor upgrades over the older model, but nothing overly substantial. That isn't necessarily a bad thing: like that older model, it offers a huge range of features for the price, including an advanced multi-function dock, real-time hazard avoidance technology, and a lifting mop system. Ultimately, it represents a good option if you're looking for a robot vacuum with similar overall functionality to a lot of other flagship models but at a slightly more affordable price point.
If you're looking for alternatives, look at our list of recommendations for the best robot vacuums, the best robot vacuums for hardwood floors, and the best robot vacuums for carpet.
The Roborock Qrevo S is a better hybrid vacuum/mop than the eufy X10 Pro Omni. The Roborock delivers superior debris-pickup performance on hard floors, gets stuck on obstructions less frequently, and charges faster while offering similar overall battery life. The Roborock's mopping system is also more effective in scrubbing away dried-on stains.
The Roborock Qrevo and the Roborock Qrevo S are pretty similar overall, though the latter makes a few minor improvements under the hood. Compared to the standard Qrevo, the Qrevo S can raise its mop pads by an additional three millimeters to lower the risk of wetting carpets during a mopping job, and its docking station has an improved base plate design to minimize leaks. However, despite the Qrevo S' nominally more powerful motor, there's no observable difference in debris-pickup performance.
The Roborock Qrevo Pro represents a slight upgrade over the Roborock Qrevo S. Unlike the Qrevo S, the Qrevo Pro's docking station washes the unit's mopping pads with warmed water and dries them with heated air. The Qrevo Pro itself also has a swing-out mechanism for its mopping pad that allows it to clean stains closer to walls.
The Dreame L10s Ultra and the Roborock Qrevo S are ultimately fairly closely matched robot vacuums. The Roborock's multifunction dock uses larger 2.5 L dirtbags, in comparison to the Dreame dock's 2.15 L bags. The Roborock also has a considerably longer max battery life, and its mopping system is a little more effective in scrubbing away stains. On the other hand, the Dreame feels more solidly built. Unlike the Roborock, the Dreame's docking station also uses warm air to dry its mopping pads.
The Roborock Qrevo S packs in a few more features than the Roborock S8+/S8. The Qrevo S has a multifunction dock that not only empties out the vacuum's dustbin but also refills its internal water tank and washes and dries its mopping pads. The Qrevo S also has a more effective mopping system. On the other hand, the S8+ feels like the more premium vacuum, with more robust build quality. Its twin roller cleaning head also does a better job of dealing with pet hair.
The Roborock Qrevo S has impressive overall build quality. It should come as no surprise that it feels similar to other related Roborock models, like the standard Roborock Qrevo or pricier Roborock Qrevo Pro; it has a body made from dense, high-grade plastic, and retains a sturdy, premium feel. There are a few downsides carried over from those models howerver: like the Qrevo Pro, finer debris can get into the hinges for its dustbin cover, to the point where it doesn't close fully. This has no impact on the operation of the vacuum, but it is disappointing for a robot vacuum in this price range.
The multifunction dock also feels similarly sturdy to the vacuum. It's a large multifunction unit that has the same range of features as the dock bundled with other Qrevo models: it contains a dirtbag for dry debris, a clean water tank for refilling the vacuum's water reservoir, and a waste water tank for holding any dirty water from the mop wash cycle.
The Roborock Qrevo S has a reasonably high number of components, just like the Roborock Qrevo. On the upside, all of the parts that need to be cleaned or replaced periodically, like the brushroll, dustbin, and vacuum filter, are simple to access and clean. Its pleated filter does collect a lot of debris; while you can tap it against the side of a trash can to dislodge some of it, you're going to want to rinse it to clean it properly. The brushroll also comes out without too much trouble, and since there are no bristles, it's a cinch to clear away any tangled hair. The only components that require tools to remove fully are the side brush, which is screwed in place, and the omnidirectional wheel, which requires a flat-headed screwdriver or a pair of pliers to lever out from its socket.
The multi-function dock incurs its own set of maintenance requirements. You'll need to dispose of its dirtbag when it's filled, wash out the dirty water tank every now and then, and refill its clean water tank. The dock also features a separate cleaning tank and water filter for the mop washing element at the base of the dock. Compared to the standard Roborock Qrevo, the Qrevo S has a differently designed dock tray meant to minimize the risk of leaks.
If you'd like to read a breakdown of the maintenance procedures involved with this vacuum, you can read the maintenance guide online. Roborock also has a series of videos regarding general maintenance, dustbin and filter cleaning, and dock maintenance for the Roborock Qrevo MaxV on their YouTube channel, which has similar overall maintenance requirements.

This unit takes up a fair amount of space. While the vacuum itself isn't big, its multifunction dock certainly is since it has to fit an internal dirtbag, two water tanks for clean water and wastewater, and a dryer for its mop pad. There's a groove at the back of the dock for storing any excess length of power cable.
This vacuum has a tiny internal dustbin with a capacity of only 0.25L, so it'll be returning to its dock quite often. There is no fill sensor that will alert you when the vacuum's dustbin is filled, but the app will send you reminders to check its fill status.
This vacuum has a multifunction dock, similar to the one included with the Roborock Qrevo. Its dock uses 2.5L dirtbags, which Roborock advertises as being sufficient for seven weeks worth of cleaning sessions. The dock also has a pair of water tanks, one to refill the vacuum's internal water reservoir and wash its mop pads, the other to hold waste water from the mop washing cycle. Each tank has a 4.25 L capacity: as per the manufacturer, this is enough for the unit to clean up to 3552 sq ft (330 sqm) before you'll need to refill the clean water tank. As with any advertised claim however, this can vary pretty drastically depending on your choice of settings.
The dock is a little less feature-dense than the outwardly similar station bundled with the pricier Roborock Qrevo Pro. On the latter, the mop washing water is heated, not just the air used to dry the mopping pads.
Its battery performance is fantastic. Like other Qrevo models, the Qrevo S has a 5200 mAh lithium-ion battery, and as a result, it provides near-identical battery performance. In its low-power 'Quiet' mode, it can run for a little over four hours, which gives it plenty of time to deal with lightweight debris. Its battery life drops to just under two hours in its high-power 'Max+' mode, which is still plenty of time to deal with stubborn messes on harder-to-clean surfaces like carpets. This vacuum will return to its dock to recharge when it drops below 15% charge, though its recharge and resume function allows it to pick a cleaning session back up from where it left off. Just note that some users have reported that leaving the 'Do Not Disturb' function on prevented the vacuum from automatically resuming a cleaning session.
Like other Qrevo models, it also features an 'Off-Peak Charging' function, which allows the vacuum to recharge only during peak hours for power demand to save on electricity costs.
You can keep track of the vacuum's battery status by checking the indicator light at the top of the vacuum, which changes color and pattern depending on the current charge status.
The Roborock Qrevo S has a pretty similar range of features to other Qrevo models. Like the older Roborock Qrevo, it has an Auto-Mop Lift feature to raise the mop pads on carpeted surfaces so that it can run vacuuming and mopping jobs within the same cleaning cycle. However, it now raises the mopping pads higher, to the tune of 10 mm instead of 7 mm.
There are also a variety of carpet-specific cleaning functions: 'Carpet First' mode has the vacuum clean carpets before anything else in its cleaning cycle to prevent them from getting wet, while the 'Deep Carpet Cleaning' mode has the vacuum run on carpets twice at a higher suction power level setting. You can also have it avoid carpets entirely. You can manually choose between its five different power level settings and two different pathing modes.
There are a variety of mopping options, too. You can choose between three water flow levels for its mopping pads: 'Low,' 'Medium,' 'High,' and 'Custom.' There are also four levels of route mapping settings, which effectively allow you to choose between fast and deep mopping on a sliding scale.
Its SmartPlan AI system is the same system found on the Roborock Qrevo Pro. It allows the vacuum to automatically select the optimal vacuuming and mopping modes for different rooms.
This unit also has Roborock's Reactive Tech system, which sits at the lowest rung of the manufacturer's hazard avoidance systems. It features a front-facing structured light sensor to spot hazards, but this type of sensor ultimately isn't as sophisticated or effective as the RGB-color camera-based system found on the Roborock S7 MaxV.
Its performance on bare floors is great. The Qrevo S is quite effective in clearing away a variety of debris on this surface type, though a small amount of finer debris can be left behind along walls and in corners.
We encountered inconsistent debris-pickup performance on this surface type. When we first ran the Qrevo S through this test, its performance lagged far behind what would be expected, especially given its overall similarity to the standard Roborock Qrevo. We ran this test again, and the vacuum delivered significantly better overall results, despite no change in settings or vacuum pathing behavior. The cause of this discrepancy is currently under investigation, and we'll update the review if we can identify a culprit.
Its pet hair pickup performance on low-pile carpets is disappointing. The Roborock Qrevo S doesn't provide enough surface agitation to lift away pet hair that's been pressed deeply into carpet fibers, especially compared to newer Roborock models with twin-roller cleaning heads, like the Roborock Q5 Max+.
This vacuum's suction force isn't very strong, largely because its suction inlet is positioned too high above the contact surface to generate a tight seal on bare surfaces, resulting in low suction power measurements. On paper, however, the Qrevo S does achieve higher maximum suction than the older Roborock Qrevo.
This vacuum's airflow performance is good overall for a robot vacuum, though hardly a step up from the older Roborock Qrevo, despite its claim of having a more powerful motor. This difference could be the result of unit-specific variance, imperceptible damage to the filter, or some other minor error.
The Roborock Qrevo S is remarkably quiet. You'll hear what people nearby are saying even when the vacuum is running in its most powerful suction mode.
The multifunction dock is noticeably quieter than that of the Roborock Qrevo, topping out at 68.6 dBA in comparison to the latter's 73.2 dBA.
This vacuum does a great job of maneuvering itself, just like other Qrevo models. Its overall room coverage is quite thorough in its 'Normal' pathing setting, and it maps quickly. It also can get quite close to walls and furniture legs, so there won't be any major gaps in coverage. Its 'Reactive Tech' hazard recognition system works quite well for the most part and will correctly identify potential hazards, such as thick carpets, as obstacles to be avoided, though that won't necessarily stop it from getting stuck in places. Unfortunately, it won't always spot smaller hazards like rug tassels or electrical cables.
This vacuum does a poor job of sealing in fine particles. Like many other Roborock models, fine allergens bypass its exhaust filter and are blown straight out of its exhaust port and LIDAR sensor.
Like many other robot vacuums, the Roborock Qrevo S does little to lift away debris in cracks and crevices. Its side brush tends to drag debris outwards instead of directing it toward the suction inlet. Running the vacuum in the 'Max+' suction mode for a second pass makes little to no difference in terms of performance in this regard.
This vacuum's stain-clearing performance is good with the water flow mode set to 'High' and the pathing set to 'Deep+.' The twin rolling pads are quite effective in dealing with dried-on stains, though it might need to make an extra pass to have more of an impact on stubborn messes.
After the vacuum has finished mopping, it'll park at the multifunction dock, where the pads are then cleaned again before being dried with a flow of warm air. In cases where the mop pads are fairly soiled, the dock does an alright job of getting them clean, though it isn't as effective as the Roborock Qrevo Pro in this respect. The latter model has a hot water washing function that gets the pads a little cleaner.
Like higher-end Roborock models, the Roborock Qrevo S has a pretty broad array of physical automation features. There's the multifunction dock, which not only empties its dustbin but also refills its water tank and washes and dries its mopping pads.
There are two physical control buttons that you can use to perform basic functions, without having to use the app. The power button doubles as a general 'Clean' button, sending the vacuum off to map your home and start a cleaning session. You can press the 'Home' button to send the vacuum back to its base station. Holding down the 'Home' button engages the spot cleaning function, in which the vacuum will clean a small area around itself. If it's on the dock, pressing the 'Home' button manually activates the self-empty function, while holding it down starts the mop wash and dry cycle.
The Roborock app has a remarkably dense feature set along with a fairly intuitive interface.
After it's mapped out your home, you can set up no-go zones, designate specific cleaning zones to spot clean, split, merge, and name those areas, manually set the surface type for different areas, set the suction and mopping modes you want for individual rooms, and even tweak the order through which it moves through each room. You can also set 'Entrapping Areas,' zones where the vacuum will slow down to minimize damage on delicate surfaces, like door thresholds and steps. It also offers multi-level mapping for up to four floors.
You can adjust its 'Less Collision' mode through two different modes, which causes the vacuum to avoid contact with walls and furniture at the expense of lower-precision scanning in tight spots.
The app also has a 'Help' sub-menu that gives you a projected service interval for its filter, brushroll, side brush, sensors, and mopping pad.
There are also quite a few configuration options for the multifunction dock. You can adjust the frequency of mop-washing cycles, the mop-washing intensity, and the mop-drying cycle length. You can also adjust how often the vacuum will return to its dock to self-empty depending on the size of your home or simply leave it up to the vacuum itself.
