We tested Roborock Qrevo Edge 2 and Qrevo S Pro: what do you get for six thousand extra?

When two robotic vacuum cleaners land on your desk for testing at once, there’s only one reasonable solution: connect both and let them compete for the same floor for a week. That’s exactly what I did with the new Roborock Qrevo Edge 2 and Qrevo S Pro, which launched on the Czech market at the beginning of July. The first one relies on a suction power of 25,000 Pa and a retractable LiDAR, the second on a reasonable compromise for 12,324 CZK. I put both machines through their paces at home – and the differences between them are more interesting than the price list suggests.

A week with two robots under one roof

On paper, they look like siblings. Both belong to the Qrevo family, both are controlled by the same app, both have a multifunctional station that washes and dries mops, refills water, and empties dust into a bag you don’t have to worry about for up to 65 days. Both also rely on brushes designed so that hair doesn’t get tangled on them. But then practice comes, and it turns out that one is a specialist in places where a regular robot can’t reach, while the other is an honest worker who can handle nine out of ten households and leaves you with six thousand extra in your wallet.

Eight centimeters is enough: Edge 2 can go under places you’re afraid to look

The main trick of the Qrevo Edge 2 model is called RetractSense. While classic robots with a LiDAR turret measure over ten centimeters and simply can’t fit under lower furniture, the Edge 2 first uses a dToF sensor to measure the clearance height above it, retracts the turret, and with a total height of 7.98 cm, goes where dust has accumulated for years. At that moment, a camera module with a 100° field of view takes care of orientation, so the robot doesn’t wander aimlessly under the bed but cleans systematically. During the week, the Edge 2 thus managed to deal with places that another robot would have politely avoided for years.

The front camera also serves the Reactive AI system, which, according to the manufacturer, recognizes over 280 types of objects – from cables to shoes to dog surprises. In practice, this means you don’t have to clean before cleaning. The robot circled the sock, didn’t eat the charger, and that’s exactly the kind of boring reliability you want from such a helper. All image data is processed directly on the device, according to Roborock.

Hair ends up in the bin, not on the brush

Suction power in Pascals is a similar discipline to megapixels in cameras – the number alone doesn’t guarantee cleanliness. Nevertheless, it’s worth mentioning that the Edge 2 offers 25,000 Pa and the S Pro 18,500 Pa, which in both cases is more than enough for crumbs, sand, and pet hair embedded in carpets. More interesting is what happens with hair. The Edge 2 uses a pair of DuoDivide brushes that comb hair from the edges to the center, where the different speeds of the two rollers tear it apart and suction carries it away. The manufacturer boasts zero tangling according to its own internal tests – and I must admit that after a week, I didn’t untangle anything from the brush, which is a small miracle in our home.

The Qrevo S Pro solves the same problem more simply: with an all-rubber main brush that directs hair to the edges, and an asymmetrical side brush that uses centrifugal force to throw it towards the ends of the bristles instead of tangling it around the axis. Less sophisticated, but functional – here too, the brush remained clean after a week.

Stations wash with hot water, but each with a different warm temperature

The docking stations for both models are what makes a robotic vacuum cleaner truly maintenance-free. The Edge 2 washes mops with water at a temperature of up to 80 °C, dries them with air at 55 °C, and newly offers a Soak mode, which first allows dried dirt to loosen. Furthermore, the one-piece washing tray cleans itself, eliminating the most annoying ritual – scrubbing the station, which is why you bought the robot in the first place, so you wouldn’t have to scrub the floor. Before cleaning carpets, the robot can automatically detach the mops in the station, so it doesn’t drag them damp across the entire apartment.

The S Pro received practically the same equipment, but a degree more modestly: washing at 75 °C, drying at 45 °C, and a removable tray that you can rinse in the sink. The stated temperatures refer to the heating element, or rather the water at the nozzles, not the mop surface. So don’t expect the cloth to burn you after washing. More importantly, the result: the mops smelled neutral and didn’t get musty even after a week, which is exactly what hot water with drying is supposed to achieve.

Qrevo S Pro: what you sacrifice compared to the more expensive model

A difference of six thousand crowns must show somewhere. The S Pro doesn’t have a camera, so it avoids obstacles only using structured light – the Reactive Tech system reliably navigates around shoes, bins, or toys, but it can no longer recognize small items like tangled cables. It also doesn’t have a retractable LiDAR, so it can’t get under the lowest furniture with its classic turret. And the SmartPlan function, which adapts cleaning to the room type, requires rooms to be manually tagged first, as it cannot recognize them on its own.

What, on the other hand, is not missing? A pair of rotating mops with 200 revolutions per minute that lift 10 mm above carpets, thirty levels of water dispensing, a child lock for physical buttons, and charging during cheaper off-peak hours. For a household with hard floors and low-pile carpets, this is equipment where you’d need a magnifying glass to find the difference compared to its more expensive sibling.

Who will be satisfied with the S Pro and who will pay extra for the Edge 2?

After a week of simultaneous testing, the dividing line is quite clear. If you have low beds and sofas, pets, long hair, or perpetually scattered cables at home, the Qrevo Edge 2 makes sense – the retractable LiDAR and obstacle recognition are precisely the features that, in such a household, are not just marketing but a daily relief. Until July 22, you can get it with an introductory 15% discount for 18,274 CZK instead of the usual 21,499 CZK, available in both black and white variants.

The Qrevo S Pro is then the choice for anyone who wants complete self-service cleaning – washing and drying mops, emptying dust, refilling water – and doesn’t need the robot to go under every piece of furniture. During the same introductory period, it will cost 12,324 CZK instead of 14,499 CZK, and at this price, its features are honestly hard to beat.

Would only a robot with eight centimeters fit under the furniture in your home, or would you save money and opt for the Qrevo S Pro?
