Xiaomi has added a new cordless vacuum to its home appliance lineup in China. Following the recent release of the 4C model, the company is now introducing the Mijia Wireless Vacuum Cleaner 4. It is priced at 999 yuan (roughly $146) and goes on pre-sale starting today through JD.com.

Mijia Wireless Vacuum Cleaner 4 Specs
The vacuum is built around a brushless motor that operates at 120,000 RPM. According to Xiaomi, it provides 230AW of suction power and a maximum suction force of 25,000Pa. This is standard for the category and is meant to handle everyday household debris like pet hair, food crumbs, and fine dust.
The device comes with a 180-degree blue light integrated into the cleaning head. The light illuminates the floor up to 30 centimeters ahead, which helps make fine dust particles more visible, particularly under furniture or in dimly lit rooms. The cleaning head is also designed to support right-side edge cleaning to help pick up dirt along baseboards.
Internally, the vacuum uses an infrared sensor to monitor the amount of dust passing through the system. When set to Smart Mode, the device adjusts its suction automatically, increasing power when it detects heavier dirt and lowering it on cleaner surfaces to conserve battery life.
To address hair wrapping around the roller, Xiaomi included a dual anti-tangle system. The main floor brush has a built-in comb structure that separates hair as the brush spins. The included motorized mite brush uses a floating mechanism to direct hair straight into the suction channel.


The vacuum is powered by a removable eight-cell 2600mAh battery. Xiaomi advertises a maximum runtime of 90 minutes, though this is limited to the lowest energy-saving setting. In the auto-adjusting Smart Mode, the battery lasts between 18 and 37 minutes, depending on the floor conditions. Using the maximum suction setting depletes the battery in about 10 minutes. Because the battery is detachable, users have the option to swap it out for a charged spare.
For filtration, the device uses a 12-cone cyclone system to separate dust from the airflow, which helps prevent the filter from clogging over time. It features a five-stage filtration setup, including an H13-grade HEPA filter that Xiaomi says captures 99.99% of particles as small as 0.3 microns.
The Mijia Wireless Vacuum Cleaner 4 comes with a standard set of accessories: the main floor brush, the mite brush, and a 2-in-1 crevice tool. It also includes an LED display on the handle to show battery levels and cleaning modes, as well as a wall-mounted dock for charging and storage.
In related news, Xiaomi has recently introduced a new titanium steel electric kettle with a 1.7-liter capacity, alongside an aluminum-body electric toothbrush that supports real-time brushing analysis.
