The sensor reads the debris and adjusts power automatically
In the ongoing human effort to reclaim time from domestic labor, Xiaomi has introduced the Mijia 4 Pro — a cordless vacuum that trades manual guesswork for automated intelligence. Launched in China in June 2026, the device brings together high-suction power, self-emptying mechanics, and a sensor that reads the floor and adjusts accordingly. It is a small but telling portrait of how the home is becoming a managed environment, responsive to its own conditions.
- Traditional vacuuming demands constant human judgment — when to push harder, when to empty, what you're missing in the dark — and the Mijia 4 Pro is engineered to eliminate each of those friction points.
- The self-emptying base transfers debris in 11 seconds into a silver-ion-treated bag rated for 100 days, removing one of the most unpleasant rituals of household maintenance.
- A real-time dirt detection sensor automatically raises or lowers suction power based on floor conditions, stretching the 90-minute battery life without sacrificing cleaning performance.
- A forward-projecting blue light reveals hidden dust up to 30 centimeters ahead, making the invisible visible in corners and along baseboards where fine particles typically escape notice.
- Priced at roughly €190 and currently sold only in China, the device sits within Xiaomi's Mi Home ecosystem — but global buyers have no confirmed timeline for when it might reach them.
Xiaomi's Mijia 4 Pro arrives as a cordless vacuum designed not just to clean, but to think. With 230 AW of suction force and a motor spinning at 120,000 RPM, the hardware is formidable — but the more interesting story is in the automation layered on top of it.
The charging base doubles as a self-emptying station. A single button press after docking transfers dust into a 3-liter internal bag in about 11 seconds. Treated with silver ions to suppress bacteria and odor, the bag is rated to last 100 days under typical household use — meaning the most dreaded part of vacuuming becomes a once-a-season task.
The vacuum's dirt detection sensor quietly handles what most users do manually: adjusting suction power based on how dirty the floor actually is. Heavier debris triggers more power; lighter passes conserve battery. Combined with a 2600 mAh removable battery offering up to 90 minutes on Eco mode, the result is a machine that manages itself. A five-stage filtration system captures 99.99% of particles down to 0.3 microns, and the filters are washable rather than disposable.
A blue light mounted on the motorized brush head projects 180 degrees forward, illuminating dust up to 30 centimeters ahead — a practical solution for the fine particles that hide along baseboards and under furniture. The brush is also designed to resist hair tangling and clean more effectively along right-side edges and trim.
Mi Home app integration allows users to track battery levels, monitor bag capacity, and receive maintenance alerts. The Mijia 4 Pro is available now in China at 1498 yuan (approximately €190), with no confirmed timeline for a global release.
Xiaomi has released the Mijia 4 Pro, a cordless vacuum designed to simplify household cleaning through a combination of raw power and intelligent automation. The device arrives with 230 AW of suction force, a 2600 mAh removable battery that lasts up to 90 minutes on Eco mode, and a feature set that addresses the friction points of traditional vacuuming: the mess of emptying, the guesswork of when to push harder, the dust you can't see.
The most immediately practical innovation is the automatic dust emptying system built into the charging base. After docking the vacuum, a single button press transfers debris from the reservoir into an internal 3-liter bag—a process that takes roughly 11 seconds. Xiaomi claims the bag can hold 100 days' worth of typical household dust before replacement becomes necessary. The bag itself is treated with silver ions to inhibit bacterial growth and reduce odors, a detail that matters more than it might initially seem for anyone who has ever caught a whiff of a vacuum's dust chamber.
The motor runs at 120,000 RPM and generates 25,000 Pa of vacuum pressure. To prevent filter clogging, the system uses 12 cone separators to extract dust from the airstream before it reaches the filtration stage. The five-stage filter captures 99.99 percent of particles as small as 0.3 microns, and the filter components themselves can be rinsed with water rather than replaced. This is engineering aimed at longevity and reduced waste.
What sets the Mijia 4 Pro apart from simpler cordless vacuums is its dirt detection sensor. Rather than forcing the user to manually adjust suction levels, the sensor reads the debris load on the floor and adjusts power automatically. When the floor is heavily soiled, suction increases; when cleaning is lighter, power drops. This balancing act extends battery life while maintaining cleaning effectiveness—a small but meaningful quality-of-life improvement for daily use.
The motorized main brush includes a blue light that projects forward at a 180-degree angle, illuminating dust up to 30 centimeters ahead. In dark corners, under sofas, and along baseboards where fine dust typically escapes notice, this light makes the invisible visible. The brush head itself is designed to resist hair tangling and to clean more effectively along walls and trim on the right side. The vacuum ships with multiple attachments: the main floor brush, a motorized brush for dust mite removal, and a dual-purpose nozzle for crevices and tight spaces.
Integration with Xiaomi's Mi Home app rounds out the feature set. Users can monitor battery levels, track dust bag capacity, and receive alerts when wear parts need replacement. The vacuum supports Xiaomi HyperOS Connect, placing it within the broader ecosystem of smart home devices.
The Mijia 4 Pro is currently available in China at 1498 yuan, roughly €190 at direct conversion. No global launch has been announced, leaving European and North American buyers waiting to see whether Xiaomi will expand distribution beyond its home market.

Why does a vacuum need to know how dirty the floor is? Can't you just turn it up and leave it?
You could, but then you're burning battery the whole time. The sensor lets it work smarter—full power when it matters, lighter touch when the floor is mostly clean. Over 90 minutes, that adds up.
The blue light seems like a gimmick. Is it actually useful?
Not a gimmick. Dust under furniture is invisible in shadow. The light makes it visible. Once you see it, you clean it. It's simple but it works.
What about the automatic emptying? Is that really worth the extra cost?
If you've ever had to empty a vacuum and gotten a cloud of dust in your face, yes. Eleven seconds, no mess, no contact with the dust. It's a small thing that changes how often you actually use the vacuum.
The bag lasts 100 days. How often do people actually replace vacuum bags?
Most people avoid it as long as possible, which means they're vacuuming with a clogged filter. This system removes that friction. You don't think about it for three months.
Why isn't this available outside China yet?
Xiaomi is cautious about global expansion. They test markets, build supply chains. It could arrive in Europe in months or years. Right now it's a signal of where cordless vacuums are heading.
