Roborock Qrevo Edge 2 Flow review

Roborock Qrevo Edge 2 Flow: Introduction

• Type: Vacuum and roller mop
• Docking: Self-empty, self-clean
• Navigation system: LiDAR

Despite its mid-range Qrevo branding, the Edge 2 Flow has some high-end features, including a roller mop, rather than the company’s more usual spinning mop pads.

In theory, roller mops have an advantage over traditional spinning pads. Clean water is constantly applied to the roller, while dirty water and debris are scraped away into a separate tank. That means the robot isn’t simply dragging an increasingly grubby mop around your home.

Add powerful suction, comprehensive obstacle detection and a self-cleaning dock, and the Qrevo Edge 2 Flow starts to look less like a mid-range compromise and more like a cut-price flagship.

Design and features

With its white finish and curved docking station, the Qrevo Edge 2 Flow certainly looks premium. Little about its design gives away the lower price.

The dock houses a 4L clean-water tank and a 3L dirty-water tank, with a 2.7Ldisposable dust bag underneath. There’s no dedicated detergent reservoir, so cleaning is performed with water alone.

Otherwise, the dock isn’t far removed from the one supplied with the more expensive Roborock Saros 20. It washes the mop roller using water heated to 75°C, then dries it with 65°C air to reduce smells and bacterial build-up.

The robot itself also borrows from Roborock’s flagship range. Its LiDAR tower can retract into the body, helping the 8.98cm-tall cleaner squeeze beneath low furniture. Reactive AI cameras at the front handle object recognition and obstacle avoidance.

Lift the top panel and you’ll find a small internal bin. The dock empties this automatically, although you’ll still need to remove it occasionally to clean the filter. Physical controls are kept simple, with buttons for starting or pausing a clean and returning the robot to its dock.

Underneath sits Roborock’s DuoDivide main brush. Its split design encourages hair to move towards the centre, where it can drop away and be sucked up rather than wrapping itself around the roller. There are also two side brushes, with the main brushes able to lift clear of the floor when they’re not required.

The main attraction, though, is the new roller mop. Fresh water is applied continuously, while a squeegee removes dirty water into a separate internal tank.

It has two particularly useful tricks. First, the roller can slide sideways to clean close to walls and skirting boards. Second, it can lift off the floor and rotate behind a protective shield, preventing wet contact with carpets.

It’s a smart system, similar to the one used by the Dreame Aqua10 Ultra Roller Complete. Even the more expensive Eufy Omni S2 lacks this kind of physical carpet protection.

Features

You can clean the entire map, individual rooms or a custom zone, but the available cleaning modes are unexpectedly limited. Options include vacuuming, vacuuming and mopping simultaneously, or vacuuming followed by mopping. There’s no dedicated mop-only mode, despite the hardware clearly being capable of it.

Four suction levels are available in the combined modes, while vacuum-only cleaning adds an extra maximum setting. Mopping offers a slightly excessive 30 water-flow levels. Choice is welcome, but the difference between levels 22 and 23 is unlikely to transform your floors.

There are also three navigation patterns and options for one or two passes, although vacuum-then-mop cleaning is restricted to a single pass. In the advanced settings, the robot can automatically rewash its roller and revisit particularly dirty areas. It’s also worth enabling the FlexiArm edge-cleaning system to get the best results around walls.es, extra parts etc.

Performance

• Powerful suction
• Good mopping on all but the toughest of stains

With a claimed 35,000Pa of suction, the Qrevo Edge 2 Flow has no shortage of power. In fact, it’s rated as high as the Roborock Saros 20 and only falls behind newer robot vacuum cleaner models, such as the Dreame X60.

On carpet, two passes at maximum power collected everything along the robot’s main route, although a couple of small patches were missed. It’s a reminder that suction figures only tell part of the story. Navigation, brush agitation and route coverage matter just as much.

Hard-floor performance was excellent, with the robot collecting all of the test dust from the centre of the room. Edge cleaning was also strong, helped by the roller mop tracking close to the wall, although a very thin line of dust remained beyond the vacuum brush’s reach.

Hair handling proved faultless. The robot collected all of the human hair placed on the carpet, with none left tangled around the brush.

Mopping performance was similarly impressive. Using the combined vacuum-and-mop mode with two passes, the Qrevo Edge 2 Flow removed dried coffee, red wine and mud stains. It collected both the loose dirt and the ground-in residue from the mud test without trouble.

Ketchup proved more challenging. The stain remained clearly visible after two passes, but applying kitchen cleaner and leaving it to work for a few minutes made a significant difference. A further four passes removed almost all of the remaining mess.

That means the roller is excellent for everyday cleaning and lighter spills, but it can still need help with dried or particularly stubborn stains.

Navigation is another strong point. The robot avoided shoes, cables and simulated pet mess, while successfully navigating beneath a sofa and around stacks of boxes in a crowded test room.

Noise reached 69.1dB at maximum power, making the Qrevo Edge 2 Flow louder than some rivals and not far removed from a conventional cordless vacuum.

Battery life is rated at up to 240 minutes on the lowest setting. Even at maximum power, the robot completed two vacuuming passes of the test area with enough charge left for additional spot cleaning. Most homes should be covered comfortably.

Final thoughts

At £799, the Roborock Qrevo Edge 2 Flow has a mid-range price but more high-end features. Its roller mop cleans well, reaches right up to edges and, crucially, can be physically covered when the robot crosses carpet. That makes it particularly well suited to homes with a mixture of hard flooring and rugs.

Vacuuming performance is strong, hair handling is excellent and navigation is reliable. The self-cleaning dock also removes most of the day-to-day maintenance.

It isn’t perfect. Tough stains may need pre-treatment, there’s no detergent tank and the absence of a mop-only mode is baffling. Yet these are relatively minor complaints when you consider the price.

There are more capable robot cleaners available in the guide to the best robot vacuum cleaners, but you’ll have to spend considerably more to get them. The Qrevo Edge 2 Flow hits a compelling sweet spot between price, performance and convenience.

How we test

When we publish our reviews, you can rest assured that they are the result of “living with” long term tests.

Robot cleaners usually live within an ecosystem, or a range of products that – supposedly – all work in harmony. And they are designed to offer a range of different cleaning options. Therefore, it’s impossible to use a robo cleaner for a week and deliver a verdict.

Because we’re testing smart home kit all day, everyday, we know what matters and how a particular smart cleaning machine compares to alternatives that you might also be considering.

Our reviews are comprehensive, objective and fair and, of course, we are never paid directly to review a device.
