Xiaomi has put the Mijia Wireless Vacuum Cleaner 4 Pro on sale in China, and the pitch is straightforward: high suction, a self-emptying dock, and enough automation to make weekly vacuuming feel slightly less like a chore. The new cordless cleaner is listed on JD.com for 1,498 yuan ($220), which puts it in the increasingly crowded middle ground between budget stick vacuums and pricier smart-home gear.
That price buys a fairly ambitious spec sheet. Xiaomi says the vacuum’s dock can empty the onboard dustbin into a 3-liter bag in about 11 seconds, while the bag is treated with silver ions to help limit odor and bacteria. The company estimates the bag should last around 100 days of typical household dust before replacement, which is the kind of convenience feature that sounds minor until you have to keep doing it by hand.
230AW suction and 25,000Pa vacuum pressure
Under the hood, Xiaomi is leaning hard on raw cleaning power. The Mijia 4 Pro uses a 120,000 RPM brushless motor rated at 230AW of suction and 25,000Pa of vacuum pressure. A 12-cone dust separation system is meant to keep debris from clogging the filters, while a five-stage filtration setup is claimed to capture 99.99% of particles as small as 0.3 microns. All of the internal filter parts can be washed with water, which is helpful because nobody enjoys paying for performance and then babysitting a filter.
The floor brush adds a blue light that projects a 180-degree beam up to 30 centimeters ahead of the vacuum, making fine dust and pet hair easier to spot in darker spaces such as under beds and couches. The roller also uses anti-tangle comb teeth, and the brush head is shaped to clean flush against walls on its right side. Those are exactly the kinds of details that separate a competent cordless vacuum from one that looks good only in product photos.
Battery life, app controls and included tools
Xiaomi powers the vacuum with a removable 2,600mAh battery and says Eco mode can stretch runtime to 90 minutes. A dirt sensor can automatically raise or lower suction depending on how much debris it detects, and the Mijia 4 Pro connects to the Mi Home app through Xiaomi HyperOS Connect. In the app, users can check battery level, monitor dust-bag capacity, and track consumable replacements, which is a neat way to make maintenance feel like a dashboard problem instead of a housework problem.
- Included accessories: motorized mite-removal brush

- Dock feature: self-emptying dust transfer into a 3-liter bag
- Runtime claim: up to 90 minutes in Eco mode
For Xiaomi, the Mijia 4 Pro fits a familiar pattern: stack premium-sounding features into a product that still lands below the truly expensive end of the market. The smart-vacuum category has been pushing toward more automation for a while, and the real competition now is not just suction numbers but how much daily maintenance a device can remove. If Xiaomi can make the bag changes, app alerts, and tangle-free brush work as advertised, this could be one of those gadgets people buy for the specs and keep for the laziness.
The bigger question is whether buyers outside Xiaomi’s home market will ever get it. For now, the Mijia 4 Pro is another reminder that cordless vacuums have become less about raw cleaning and more about how much of the annoying stuff they can hide from you.
