The vacuum cleaner uses the electric motor to generate high-speed airflow to form negative pressure, sucking in impurities and then purifying and discharging them through the filter. There are various types. The upright type is suitable for large areas, with strong suction but inflexible; the canister type is suitable for narrow places; the handheld type is portable and used in small areas; the robot type is smart and convenient. In terms of performance, the suction power is measured in Pascals or air watts, the filtration system prevents secondary pollution, and the battery life affects the use time of the cordless vacuum cleaner. Daily maintenance requires regular cleaning of the dust box and filter, checking the suction nozzle and straw, and storing in a dry and ventilated place.

When using a vacuum cleaner, you need to pay attention to multiple aspects before and during use. Before use, read the instructions carefully to understand the functions, operations and maintenance points; check whether the dust head, suction pipe and other accessories are complete and installed correctly, and whether the power cord is damaged; clean up large debris on the floor in advance to prevent blockage. When using, choose appropriate accessories according to the scene and adjust the suction power as needed; when vacuuming, keep the nozzle close to the cleaning surface and move at a constant speed to avoid excessive force; a single use should not exceed 2 hours to prevent the motor from overheating. In addition, it is strictly forbidden to use a vacuum cleaner to clean flammable materials, wet soil, sewage, metal debris, sharp objects, etc., so as not to damage the machine or cause danger.

When choosing a vacuum cleaner, it's not just about its stylish appearance and cool colors; more importantly, pay attention to its cleaning performance. Make sure the vacuum cleaner you select meets your cleaning needs. If you're a pet owner, you also need to consider its ability to remove pet hair.
