Xiaomi Robot Vacuum X20 Max review: one-minute review

The Xiaomi Robot Vacuum X20 Max seems like a slam dunk in the robot vacuum space. Positioned right in between the budget and upper mid range sections of the market, it delivers strong vacuum and mopping performance that make it capable of tackling a wide variety of messes in your home.

With LiDAR technology, its mapping is excellent and the robot vacuum does a great job of navigating unexpected obstacles that it might encounter during a clean. The design isn't the most exciting, though it still has a good range of features like an extendable mop arm and automatic carpet detection.

The dock is large, which might make it tricky to fit into smaller homes, but it's pretty capable as well, with hot water washing and air drying capabilities to keep the mop pads clean between uses.

It's all underpinned by a competent app that's easy to use and offers key functions such as being able to schedule cleans, restricting the robot vacuum to certain rooms, and allowing you to customize the vacuuming power and amount of water used by the mop.

The elephant in the room is that my unit developed a fault after a year of testing, occasionally spilling water during a mop pad clean. It's unfortunate and, even though it doesn't seem widespread, makes this model difficult to recommend unreservedly.

Xiaomi Robot Vacuum X20 Max review: price, range & availability

List price $999.99 / £499.99 / AU$1,199
Launched late 2024
No longer available in Australia
Limited stock in the US

The Xiaomi Robot Vacuum X20 Max has a list price of $999.99 / £499.99 / AU$1,199, and is readily available via the brand’s website in the UK. It often receives discounts too, taking the price down by £100 or so around major sales events. At this price it sits neatly between the budget and upper mid range price brackets, coming in much more expensive than under $300 / £300 / AU$500 favorites like the Roborock Q7 M5 but cheaper than the likes of the Eufy X10 Pro Omni, which goes for $799.99 / £799 / AU$1,699.95.

That latter model is a good point of comparison here, as it also features mop and similar LiDAR sensor setup. With this in mind, the Xiaomi Robot Vacuum X20 Max is very solid value - especially if you get it at that reduced price point. Accessories like replacement brushes, dust bags, and mop pads are all available via the Xiaomi website at pretty reasonable prices too.
