Roborock Qrevo S Robot Vacuum Review

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.

The Roborock Qrevo S incurs high recurring costs.

• Brushroll: You'll need to replace the brushroll after 300 hours of use or every six to 12 months. Replacements can be purchased from Roborock's online store.
• Side brush: The side brush has a service life of 200 hours or approximately three to six months of use. You can buy a two-pack of replacements from the company's website.
• Filter: The filter needs replacing following 150 hours, according to the maintenance tab of the companion app, or every six to 12 months. You can buy replacements in packs of two from the manufacturer.
• Mop pads: You should replace the mop pads every one to three months. Replacements can be purchased from the company's website.
• Multi-function dock dirtbag: The dirtbag has an advertised capacity of 2.7 L. Replacements can be purchased from Roborock's website.

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.

The performance on high-pile carpets is fair. The Roborock Qrevo S does a good job of handling large- and medium-sized debris on this surface type, but it does little to clear away finer material embedded more deeply in carpet fibers, especially along walls and in corners.

The Roborock Qrevo S does an alright job of cleaning debris on low-pile carpets. It's quite effective in dealing with large- and medium-sized debris like cereal or rice, but it does tend to leave behind finer debris, especially in corners and along walls.

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.

The Roborock Qrevo S isn't designed for dealing with liquid spills. It can clear away small spills by soaking them away with its mopping pads, but having the vacuum suck up liquid is likely to damage it.

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.
