Mijia Vacuum Cleaner 4 Pro: power and accessories for the whole home

Review of the global F204 version based on official documentation and journalistic sources. Does not include hands-on testing. Xiaomi promotional images.

A handheld vacuum starts to make sense when it solves what the usual floor-cleaning routine misses: crumbs on a chair, dust between cushions, or dirt behind furniture. The Mijia Vacuum Cleaner 4 Pro aims to cover those situations with a broad set of accessories.

That approach makes it interesting both for cleaning the home and for complementing a robot vacuum. To assess its proposition, it is worth separating the useful features from the maximum figures and understanding how they change depending on the accessory and selected mode.

Power with a more practical automatic mode

Xiaomi advertises up to 280 AW of suction. Its support page ties that figure to using the 2-in-1 crevice nozzle in Turbo, so it does not represent constant power with every head. The configuration used matters as much as the number.

The available modes are Eco, Auto, and Turbo. In Auto, the sensors adjust suction based on dirt levels, while the LCD screen communicates the detected level using colors. Our interpretation is that this would be the most convenient starting point for daily use: it lets you reserve Turbo for specific tasks and Eco when prioritizing runtime.

The stated power looks promising, although it does not predict how many passes it will need on a carpet. That requires checking debris pickup under real-world conditions.

Maximum power and automatic adjustment address different usage scenarios.

The accessories expand its usefulness

The global accessory set includes a floor head, electric mini brush, sofa brush, 2-in-1 crevice nozzle, and pet brush. It also adds a rigid extension, an articulated accessory, a hose, and the wall-mounted charging dock.

The advantage is being able to adapt the device to each task: cleaning rooms, working on fabrics, or reaching narrow spaces. If a robot vacuum already maintains the floor, this flexibility may add more value than repeating its route with another vacuum.

The set also incorporates anti-tangle designs in the floor and small heads. Their goal is to reduce maintenance, although it is still worth checking the rollers. When comparing deals, you need to confirm which accessories are included: that list significantly changes the value of the package.

Reaching under furniture without bending down as much

The articulated tube lets you angle the assembly to work under sofas and other furniture. It is a useful solution for reaching low areas with a less demanding posture, as long as there is enough space for the head to fit underneath.

Xiaomi states 3.2 kg for the device with battery, tube, and floor head; the body with battery weighs 2.15 kg. The difference matters when lifting the vacuum to clean furniture or elevated surfaces.

From an ergonomic standpoint, it is worth considering how long it will be used in those positions. Weight alone does not reveal the balance of the handle or wrist fatigue: sustained comfort still requires hands-on testing.

The articulated accessory makes it easier to angle the tube under low furniture.

Blue light and attention to the right edge

The blue lighting helps distinguish dust on the floor, with an advertised 180° coverage and about 30 cm of reach. It serves a different function from the dirt sensor: one helps the user see; the other adjusts suction in Auto.

The head is also designed to get close to edges on its right side. That orientation is relevant when cleaning along baseboards: you should not expect the same behavior on both sides.

Xiaomi’s own support page acknowledges that debris may remain in corners and recommends changing the angle or using the crevice nozzle. The combination provides tools to better direct cleaning, but it does not guarantee that every corner will be solved in a single pass.

The light reveals dirt; the side design lets the right edge get closer to the wall.

Battery life changes with each accessory

The advertised 90 minutes correspond to Eco mode with the 2-in-1 crevice nozzle. With motorized heads, the published runtimes are different.

These are approximate times stated by Xiaomi. For a typical floor-cleaning session, the Auto range is more useful than the advertised maximum. The longest runtime and maximum power are not achieved simultaneously.

The 3,750 mAh battery is removed with a button and without tools. The package includes only one unit. Being able to replace it is a maintenance advantage, although it is worth checking the price and availability of the replacement before buying.

A full recharge takes about four hours, according to Xiaomi support. If it runs out during cleaning, continuing will depend on having another battery or waiting for it to charge.

The battery is removable; a second unit requires an additional purchase.

Filtration and a dustbin that requires attention

The spec sheet advertises five stages of filtration, an H14-grade HEPA filter, and 99.99% efficiency in the cited test for particles from 0.3 to 10 μm. It is a laboratory result, which does not allow clinical benefits to be promised.

The FAQ distinguishes between a maximum vacuumed capacity of at least 0.5 liters and an effective capacity of at least 0.35 liters. The latter is the more useful reference for anticipating emptying frequency.

Maintaining the device matters too. Xiaomi recommends checking for blockages in heads, tubes, and filters when suction is weak, and fully drying washed components before reinstalling them. To assess long-term cost, it is important to know the availability of original consumables.

A versatile proposition, conditioned by the final price

The main appeal of the Mijia Vacuum Cleaner 4 Pro lies in combining tools for different surfaces with a removable battery and articulated tube. Our document-based assessment is favorable for anyone looking to cover floors, furniture, and textiles, or to complement a robot vacuum with manual cleaning.

Its convenience will depend on the package price, warranty, and available spare parts. Before choosing it, it is worth thinking about which accessories will actually be used and how much you will depend on Turbo. The proposition is complete; practical testing is still needed to confirm its performance and comfort.
