Expert’s Rating
Pros
- Swing-out side brush and mop pad
- Integral voice control
- Fits under low furniture
- Quick mapping
Cons
- Better on hard floors than carpet
- Expensive
- Some app options are hard to find
Our Verdict
There’s plenty to like about Roborock’s Qrevo Slim mopping robot vacuum. Its voice control doesn’t require a smart speaker as the middleman, the mapping is quick and adaptive, and thanks to the dock, there’s minimal maintenance required. Plus its side brush and a mop pad cleverly reach out into corners. Yet although it’s loaded with tech to make using it easier, the cleaning performance overall didn’t wow us.

Billed as the slimmest robot vacuum with 3D time-of-flight, or ToF, technology (a method for measuring distance between a sensor and an object), Roborock’s Qrevo Slim mopping robot vacuum promises a lot.
In addition to not bumping into objects around your home, it’s low enough to scoot under furniture, has an RGB camera to spot dirt, and can detect floor types, ramping up the suction and discontinuing mopping for soft surfaces.
However, it’s the built-in voice control which doesn’t require a smart speaker that you might value the most: it’ll respond to a host of commands, from starting and stopping cleaning to sending it back to the dock.
If you’re in the US and buying before Black Friday 2024, you can get $400 off the MSRP from Roborock and Amazon.
Design and Build
- Low-profile robot
- 1,000Pa suction
- Robot responds to direct voice commands
The first thing you’ll notice about the Qrevo Slim is its size: it’s a sleek 8.2cm tall, allowing it to sweep along kitchen plinths and access the space below beds and sofas (its diameter is pretty average at 35cm).
It’s also fairly lightweight at 4.2kg so easily carried to another floor. Like its dock, the robot is finished in a mix of glossy and matt black plastic.

This is combined with layers of navigation: LiDAR sensors (two at the front, one at the back) and three cameras (an RGB and infrared at the front, an infrared at the back).
Underneath, there’s a pair of rubber rollers for sweeping up dirt along with 11,000 Pa suction, a side brush that reaches into corners and around furniture legs, and two mopping pads (the right one of which also reaches).

On top, for those who like hands-on controls, is a single button that can be pushed a few different ways to either spot clean, start cleaning, send the robot back to the dock, mop only or engage the child lock.

It’s paired with an upgraded Multifunctional Dock 3.0, which washes and dries the mop pads, and contains a larger dust bag for the Qrevo Slim to empty into.
What’s clever though, especially for those who are less tech savvy, is the built-in voice assistant, which doesn’t need to be connected to Wi-Fi to work. By saying ‘Hello Rocky’, you can, for example, ask the Qrevo Slim to clean a specific room (once mapped), or adjust the suction level, thanks to a host of preset commands available in the app. It’ll even remember your conversation on a chat history screen.
Performance and Features
- Easy to edit maps
- Customised cleaning
- Colour camera
Go back by only a few years and robot vacs were still taking an age to map a floor. However, this isn’t so for the Qrevo Slim. We set it off mapping ours and it was done in a few minutes, presenting a floorplan that was easy to divide and name in the app into different spaces.
There are multiple options for customising your clean
We liked that it recognised that there were different floor types and presented this on the map, although if it gets it wrong, you can change it.

Another plus of the app is that there are multiple options for customising your clean: it’s possible to choose a fast cleaning mode (great for when guests are about to descend or on your way home), alter how loud the robot’s beeps are (plus there’s a do not disturb option so it won’t make noise when you’re sleeping), four options each for mop water flow and suction power, and you can choose whether you’d like it to go round once or twice.
Or, if you’d prefer the robot to make those decisions, there’s Smart Plan, which makes the cleaning choices for you.
That said, there’s some useful stuff, such as choosing off-peak charging, that’s hard to find, as is spot clean, hidden under a settings menu called Pin n Go, so digging through the menus is a must.
We found the remote viewing via its colour camera interesting but gimmicky. It can be used to take photos of your pets, but this option wasn’t enabled in our app.
