Roborock Qrevo Edge Review – Our New Best Pick

Welcome to Vacuum Wars and to our review of the Roborock Qrevo Edge. It’s a newer robot vacuum model from Roborock that has almost identical features to their flagship model, the Roborock Qrevo Curv. We bought one and have been testing it in various ways over the past few weeks, and other than the lack of a curvy dock,  we can’t find many differences at all between the Edge and the Curv—except for one very important difference, which I think gives the Edge the edge.

In this review we’ll explain everything you need to know about the Qrevo Edge and explain how it achieved such a high ranking in our Top 20 Best Robot Vacuums.

Starting Off With the Basics

The Qrevo Edge is a LiDAR-based smart robot vacuum/mop combo with obstacle avoidance sensors and a fully featured charging dock that washes and dries its mop pads (among other premium features). The Qrevo Edge currently has the same list price as the Curv, but at least early on, the Edge has been selling at a significantly cheaper price. If that trend continues, the Edge is a no-brainer buy over the Curv. 

Hardware and Cleaning Performance

Brushes and Hair Pickup

One of the big pros with the Qrevo Edge is the hardware features on the robot itself. It has Roborock’s latest brushes, like the DuoDivide main brush, which is essentially two brushes with a gap in the middle. That gap channels longer hair to the center, which leads to fewer tangles—previously, this was only seen on the Curv.

It also has Roborock’s new FlexiArm Arc side brush design, which reduces tangles and automatically extends when it senses corners. This is a game-changer for corner coverage.

It did well in the various hair tests we do: for example, 0% of the 7-inch hair got tangled in its brushes, whereas the average is almost 40%. It also picked up a better-than-average 80% of the flattened 2.5-inch pet hair on carpet.

Debris Pickup

Those two brushes worked well together at sweeping up debris on both hard floors and carpets, where it excelled with everything we tested.

It was also much better than average with carpet deep cleaning, where we embed sand into medium-pile carpet and weigh the dust bin before and after a timed run.

Power Tests

It had virtually identical scores to the Qrevo Curv with things like suction and airflow tests across the board.

Threshold Crossing

Like the Curv, the Edge has Roborock’s AdaptLift chassis, a mechanism that raises its front wheel so it can cross thresholds up to 40 mm, which is almost double what robot vacuums could cross before this. Once we set up where the threshold was in the app, the Edge “tested” it at first, then realized it needed a running start to cross—so it did, both coming and going. Its threshold crossing works great and will allow a lot of people to have robot vacuums who otherwise couldn’t because of threshold issues.

Dock Features

Its multi-functional dock is a huge pro. It has all the features that other flagship robots do:

• Automatically empties its dust bin into a 2.7 L disposable bag (which Roborock says will last 7 weeks before needing to be changed).
• Washes its two mop pads with hot water.
• Dries them with hot air.
• Refills its mop tank with water or a water solution mix.

It also has slightly larger water tanks than the Curv because of the different-shaped dock. It has an internal dirty-water sensor, which detects how dirty the mop water is in order to determine how much it needs to wash its mop pads, or if the floors need additional passes.

There’s a self-cleaning mopping tray, as well as the ability to remove that tray for periodic deep cleaning.

Mopping System

The mopping system itself was also good. It uses two spinning mop pads, one of which automatically extends to mop edges more closely. In our dried-on stain mop test, the Edge got a score of 106 (above average), which was similar to the Roborock Qrevo Curv.

However, there was a big difference here which benefits the Edge over the Curv, which I’ll return to later. In short, though, the Edge uses significantly less water overall, reducing the likelihood of streaks.

Obstacle Avoidance Sensors

Another pro is that the Roborock Edge has obstacle avoidance sensors. It uses the same system as the Curv—3D structured light plus an RGB camera—and it’s trained to recognize 62 objects, which is fewer than many of its flagship competitors.

As far as obstacle avoidance performance in our tests, it was just okay—better than not having it, of course, but still a little above average. It avoided about 66% of the objects we tested, which is the same score as the Curv. In our opinion, obstacle avoidance is generally one area where Roborock has lagged behind some premium competitors.

Battery Life and Navigation

Another pro is its battery life. It has one of the larger batteries in the industry, with an official battery life of 240 minutes on low power. We tested it on its other power settings on a fixed floor plan and determined it has significantly higher-than-average efficiency at 1.9 minutes per percentage point, and an estimated 1,677 square feet per charge. Those scores were nearly identical to the Qrevo Curv’s scores.

	Roborock Qrevo Edge	Roborock Qrevo Curv	Average
Official Battery Life (Low Power)	240 min	240 min	155 min
Battery Efficiency*	1.98 mins per %	1.89 mins per %	1.30 mins per %
Square Feet per Charge (Estimated)*	1677 ft²	1673 ft²	984 ft²

Its navigation is also a pro. It uses top-mounted LiDAR to map and navigate your house, has multi-level maps, fast mapping, and great coverage. It seemed really smart and didn’t get stuck. Once again, it had nearly identical navigation scores to the Curv.

App Features

The last pro to mention is the app. It’s one of the best apps in the business (we always say that). It has really high ratings on the app stores, gives you granular control over almost all the features of the robot and the dock, and is updated frequently.

Any Cons?

Besides the lackluster obstacle avoidance mentioned earlier, there is one more con to address.

Water Usage (Streaking Concern)

The other con is about its water usage. During the mop test, we weighed a paper towel on a fixed area after the run. We are retesting most robot vacuums we own this way because we now think water usage is more important than we used to.

It looks like both the Qrevo Edge and Qrevo Curv use more water than average, making them more prone to streaks than some others. However, the Qrevo Curv uses almost double the amount of water that the Qrevo Edge does, which makes streaks much more likely with the Curv than with the Edge.

This is something we think Roborock can fix in a software update if they want to. In the meantime, you should just use both of these on their lowest water settings for best results. The bottom line is that while both use a lot of water, the Edge uses about half as much across all its settings, which is good. So, all things being equal, the Edge is the clear choice for mopping because of this.

Final Thoughts

This all makes our final rankings very interesting. For context, the Qrevo Curv has ranked number one on our Top 20 Robot Vacuums list for several weeks now. After adding up all the scores, the Qrevo Edge is ranking at number two, only slightly below the Qrevo Curv—mostly because the Curv had slightly better scores on some tests (like the 2.5-inch pet hair pickup test).

Even then, if we ran that test five times in a row, they’d probably tie, since they have all the same specs and features. So, it’s a really close score either way.

However, by the time you’re watching this, we wouldn’t be surprised if the Roborock Qrevo Edge becomes our new number one pick, because we’ll be done testing the water usage scores on all the other robot vacuums, and we’ll update the algorithm on our top 20 list to penalize robots that use too much water. This will almost certainly mean the Qrevo Curv will lose its top spot to the Qrevo Edge.

And if the price remains similar to how it’s priced now, that makes the Qrevo Edge an obvious no-brainer, if you can deal with the so-so obstacle avoidance systems on both.
