The application of the car vacuum cleaners is not enough to suck immediately, and some small key points should be paid attention to.

1. Before application, check whether the fuse of the switching power supply can bear the current flow during the operation and operation of the vacuum cleaner. Before plugging in the switching power supply, first check whether the power switch of the vacuum cleaner is turned off.

2. When the dust of the vacuum cleaner reaches a certain level, or it should be removed immediately after each application, it can increase the service life of the car vacuum cleaner.

3. During the whole process of application, pay attention to abnormal noise or sound. Once you find it, stop it immediately. It may be that something is blocking the plastic straw. If you use it again, it is likely to damage the motor.

4. It is very easy to blow dust with a car vacuum cleaner. The windows and doors should be opened, and the central air conditioner should be turned on to a larger size. I must wear a mask to prevent dust from being inhaled through my nose and mouth.
