Xiaomi has put its Mijia Cordless Vacuum Cleaner 4 Max on sale in China, and the pitch is as blunt as the spec sheet: 280 AW of suction, up to 100 days without cleaning the dustbin, and a launch price of 2,045 yuan, or about $300. After the launch offer, the listed price rises to 2,351 yuan, or about $345, which puts the Mijia 4 Max squarely in premium cordless territory without tipping into the most expensive tier.
The company is aiming at buyers who want a do-it-all stick vacuum but also hate maintenance, which is a pretty large audience. Dyson and other high-end rivals have spent years selling performance; Xiaomi is trying to bundle performance with a self-emptying base and a slightly less painful price tag.
Xiaomi Mijia 4 Max 280 AW suction and 800W motor
Inside the Mijia 4 Max is an 800W brushless motor spinning at 150,000 rpm, the kind of number Xiaomi clearly hopes will sound reassuring in a showroom. The headline figure is 280 AW of suction, which is enough to make this model look very serious on paper, even if real-world results still depend on floor type, brush design, and how much cereal your household has decided to scatter.

Self-emptying dock for the Mijia 4 Max
The charging base, model F201-JZ, is rated at 685W and uses a dual-channel dust collection system. Xiaomi says that setup can keep the dustbin from needing attention for up to 100 days, which is the kind of promise that turns a boring appliance into a mild act of revenge against housework.
The vacuum itself includes a brush with 180-degree blue lighting to expose hidden dust, plus intelligent dirt detection and Xiaomi Pengpai, better known as HyperOS Connect, for smart-home integration. That pushes the product beyond simple suction bragging into the usual connected-home territory where every appliance wants a seat at the platform table.
Battery, filtration and size
Xiaomi says the built-in 4000mAh battery delivers up to 90 minutes of continuous use. Air cleaning is handled by an 8-stage filtration system, while the full setup stands 1,173 mm tall with the station and 932 mm for the cleaning unit alone.
- Battery: 4000mAh
- Runtime: up to 90 minutes
- Filtration: 8-stage fine filtration
- Total height with station: 1173 mm
- Cleaning unit height: 932 mm
- Weight: 10.2 kg
The 10.2 kg weight of the F201 vacuum body is not exactly featherlight, so this is clearly a machine built more for capability than quick one-handed darting around the sofa. The open question is whether Xiaomi can turn those headline numbers into a meaningful challenge for established premium cordless players, or whether this remains another very capable China-only launch that makes everyone else sharpen their price tags.
