Vacuum cleaner
**Working Principle**
After the device is powered on and started, the side brushes gather debris from corners toward the main brush area. The main brush rotates at high speed to lift the debris, while the built-in fan generates negative pressure suction to draw dirt and dust into the internal dustbin. Smart models use radar, cameras, or infrared sensors to identify walls, furniture, and obstacles, automatically planning cleaning paths and turning or avoiding obstacles such as steps or blockages. Models with a water-spraying function suppress dust by spraying clean water, while some integrated sweeping-and-washing units can simultaneously recover wastewater, completing the entire cleaning process of sweeping, vacuuming, spraying, and wastewater recovery.
