The Xiaomi Mijia Cordless Vacuum Cleaner 4 Pro arrives shortly after the pricier 4 Max, offering many of the same features at a more wallet-friendly 1,499 yuan (~$220). It’s designed to cut down on manual upkeep with smart dust collection, but don’t expect magic.
- Automatic dust transfer into a 3-liter antibacterial bag claims 100 days of maintenance-free use
- 120,000 RPM brushless motor pushes up to 230AW suction power and 25,000Pa vacuum
- Blue light dust detection and dual anti-tangling brushes improve cleaning in tricky spots
- Removable 2,600mAh battery promises up to 90 minutes runtime
Flagship Features, Mid-range Reality
On paper, the 4 Pro mimics high-end vacuums with Xiaomi’s dual-duct self-collecting dust system. The vacuum automatically empties dust into a 3-liter bag housed in the charging base, coated with antibacterial silver ions. Xiaomi claims this means users can avoid dust bag changes for up to 100 days. That sounds great, but real-world grime and heavier debris will likely shorten that interval.
The vacuum’s motor spins at 120,000 RPM, generating 230AW suction and up to 25,000Pa vacuum pressure. These numbers suggest it can handle everything from pet hair to cat litter. However, suction power isn’t the full story — brush design and airflow are equally important for actual cleaning performance.
Tech That Tries to Outsmart Dirt
The standout feature is the 180-degree wide-angle blue light for dust detection. It’s intended to reveal fine dust lurking in dark corners — under beds or sofas — where normal cleaning misses. This is a clever addition but remember that blue light can only highlight dust; thorough cleaning still depends on suction and brush action.
The dual anti-tangling brush system targets hair wrap issues, a common vacuum headache. Xiaomi claims the vacuum can handle up to 300 long hairs without jamming. While this reduces maintenance, hair tangles are rarely eliminated entirely.
Battery Life vs. Real Usage
The 4 Pro’s removable 2,600mAh battery promises up to 90 minutes of runtime. That’s solid on paper, especially for a cordless vacuum at this price. The catch is 90 minutes likely applies to low power modes. Using high suction, 5G connectivity for smart features, or the blue light will sap battery faster.
Filtration That’s Not Just Hype
It features a five-layer filtration system that claims to filter 99.99% of particles down to 0.3 microns. This should help with indoor air quality, particularly for allergy sufferers. Still, filtration efficiency depends on maintenance and proper filter replacement — not just specs.
GizmoIndo’s Take
The Xiaomi Mijia Cordless Vacuum Cleaner 4 Pro packs in flagship-style features at a mid-range price. It’s a solid step down from the 4 Max with some compromises but smart dust collection and blue light detection add real value. The catch is that Xiaomi’s maintenance-free claims and battery runtime should be taken with a grain of salt — real-world use always exposes gaps between marketing and reality.
Still, for $220, the 4 Pro offers a compelling balance of tech and price, making it a decent option for users wanting smart cleaning without the flagship hit to their wallets. Just don’t hold your breath for flawless hair tangle prevention or weeks without dust bag attention.
