The vacuum cleaner uses a motor to drive the fan to rotate, generating negative pressure (vacuum) inside the body, thereby sucking in external air and dust. The inhaled air passes through a filtration system, where dust and impurities are trapped by a filter or dust bag, while clean air is discharged. Modern vacuum cleaners are typically equipped with multi-layer filtration systems (such as HEPA filters) that can effectively capture small particles, making them suitable for use by people with allergies.
Types of vacuum cleaners
Wired vacuum cleaner: Stable power, suitable for large-scale cleaning, but limited by wire length.
Wireless vacuum cleaner: portable and flexible, suitable for small spaces or quick cleaning, but with limited battery life.
Robot vacuum cleaner: Automatic cleaning, suitable for daily maintenance, but with weak cleaning power.
Handheld vacuum cleaner: lightweight, suitable for cleaning in cars or small areas.
Usage and maintenance
Regularly clean or replace the filter and dust bag to maintain suction.
Avoid inhaling sharp or damp objects to prevent damage to the motor or blockage.
Adjust the suction or brush head according to the type of floor (carpet, hard floor).
Purchase suggestions
Choose the appropriate type based on cleaning needs.
Pay attention to parameters such as suction, range (wireless), noise, etc.
Choose well-known brands to ensure after-sales service and parts supply.
Vacuum cleaners are important tools for modern household cleaning, and proper use and maintenance can extend their lifespan and improve cleaning efficiency.
