Xiaomi just launched their latest robot vacuum – the S40, and it is a very affordable and comfortable addition to any household to help with keeping the house clean.
Overall Look & Feel
At just 9.8cm tall, the Xiaomi Robot Vacuum S40 features a clean, minimal design that fits easily into most modern interiors. Its white exterior blends in nicely with your surroundings, and the compact dock can be placed neatly near any power outlet. Once it’s up and running, the S40 quietly gets to work without drawing too much attention – both visually and audibly.
Xiaomi Home App
With the Xiaomi Home app, you can control the robot vacuum remotely, whether you’re on the couch or halfway across the world. You can view cleaning history, schedule cleanups, and even activate the child lock feature – especially handy if you’ve got little ones or pets at home. It’s a user-friendly way to manage your home’s cleanliness without being physically there.
Vacuum Function
The S40 is built with strong suction power and an anti-tangle design – great news for households with long hair or pets that shed. Its V-shaped main brush has a built-in comb-like structure that helps prevent tangling as it moves around. The side brushes also feature anti-tangle engineering, working in sync with the main brush for a smooth, thorough clean.
With four suction modes – Silent, Standard, Strong, and Turbo – the robot vacuum is flexible enough to tackle everything from light dust to stubborn coffee grounds. You can switch modes depending on your cleaning needs for the day.
Mop Function
Mopping is just as convenient. Through the app, you can control the water flow based on how much cleaning power you need at any given time. With three adjustable levels, the mop pad stays evenly damp, delivering an efficient wipe-down across your floors – without soaking them.
LDS Navigation
Thanks to LDS navigation, the robot vacuum maps out your home quickly and accurately. This helps minimize missed spots or inefficient routes, so it spends less time circling aimlessly and more time actually cleaning.
Customizable Settings
One of the most useful things about the S40 is how customizable it is. Through the app, you can tailor your vacuuming and mopping schedule to fit your lifestyle – set different routines for weekdays and weekends, adjust cleaning zones, or optimize for carpeted areas. It gives you control without complication.
Multiple Sensors
The Xiaomi Robot Vacuum S40 comes equipped with step detection, auto-docking, and the ability to cross door thresholds up to 20mm. These are features you’d expect in higher-priced models, so it’s nice to see them here. It handles common home obstacles well and navigates smoothly across different rooms.
Battery
Xiaomi claims up to 180 minutes of run time on a full charge in Standard mode. In our tests, we found the S40 comfortably cleaned a 506 sq ft apartment in about 100 minutes, with both vacuum and mop functions running. That’s more than enough for most smaller homes or apartments in a single session.
Yay or Nay?
We’ve tested a few robot vacuums over the years, and if you’re looking for a capable, easy-to-use robot vacuum that doesn’t cost a fortune, the Xiaomi Robot Vacuum S40 is a solid pick. It combines thoughtful features – like app controls, strong suction, and customizable routines – at a very wallet-friendly price point. While it may not have all the bells and whistles of higher-end models, it delivers reliable, everyday performance where it counts.

The Xiaomi Robot Vacuum S40 starts from S$229, and is available on the following platforms: mi.com, Shopee, Lazada.
