An ultra-slim robot vac and mop that’s a great listener
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.
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

- 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
