Self-Emptying Dock and Filtration
The vacuum comes with a dual-airflow self-emptying system built into its charging dock.
When the vacuum is docked, pressing a button transfers debris from the onboard dustbin into a 3-liter bag inside the station, a process that takes about 11 seconds.
The dust bag is treated with silver ions to control odors and bacteria. Xiaomi estimates it can hold roughly 100 days of typical household dust before needing replacement.
For standard cleaning, the vacuum uses a 120,000 RPM brushless motor that generates 230AW of suction power and 25,000Pa of vacuum pressure.
It relies on a 12-cone system to separate dust from the air, which helps prevent internal filters from clogging over time.

The exhaust air passes through a five-stage filtration setup that captures 99.99% of particles as small as 0.3 microns.
All internal filter parts are washable with water.
Brush Head and Battery
The main motorized floor brush features a blue light that projects a 180-degree beam up to 30 centimeters ahead, making fine dust and pet hair more visible in poorly lit areas.
The roller brush includes an anti-tangle design with built-in comb teeth to pull hair off the roller as it spins.

The brush head is also designed to clean flush against walls on its right side.
The device is powered by a removable 2,600mAh battery. Xiaomi says it can run for up to 90 minutes on a single charge in Eco mode.
It also has a dirt sensor that automatically adjusts suction based on the amount of debris detected on the floor.
Smart Connectivity and Accessories
The Mijia 4 Pro connects to the Mi Home app via Xiaomi HyperOS Connect.
The app allows users to check battery levels, monitor dust bag capacity, and see when to replace consumable parts.
