We reviewed it in April and gave it 4.5 out of 5 stars. Robot vacuums are expensive and even at £500, this rates as a mid-priced cleaner. But you’ll get all the functionality of a more expensive robot.
The 920 uses Lidar to navigate, which means it will create a map of your home that you can add exclusion zones to in the free app. You can then keep the robot out of your bedroom if you don’t have time to pick up your clothes before a clean, or out of the living room if the floor’s covered in Lego.
It also has a mop function. This is easy to use and again, you can create cleaning zones in your home so that the robot will, for example, only mop the kitchen floor and not your bedroom carpet.
You can also schedule cleaning and it’s Alexa compatible, so you can control it with voice commands. It has a 110-minute battery life and good suction (1,200 Pa).
It’s a relatively low-profile machine, at 10cm high. You should measure key pieces of furniture such as your sofa before you buy a robot vac, but for most people this will be a good height to get under much of the furniture.
The Ozmo 920 is also a good climber, so it won’t get stuck on raised thresholds or lamp bases and the like. It's a great all rounder and we'd recommend it but hurry - the deal is on today only.
