1. Pay attention to the power supply of customized car vacuum cleaners: when the car vacuum cleaner is used for a short time, you can turn the car key to the ON position and then plug it into the cigarette lighter for use, but if it is used for a long time, more than 5 minutes, In order to protect the car battery, it is best to use the vacuum cleaner after starting the vehicle.

　　2. The cigarette lighter of the customized car vacuum cleaner should be gently inserted and unplugged: the cigarette lighter on the car is often used to charge the mobile phone, use the driving recorder, and then use the vacuum cleaner.

　　3. Before using the vacuum cleaner, pay attention to installing the front head: the new car vacuum cleaner generally needs to install the front suction head by itself, which is used to suck relatively small things, so you can't use the vacuum cleaner to suck too big things, so as not to block the vacuum cleaner.

　　4. Customized car vacuum cleaners often dump the garbage in the vacuum cleaner: when the vacuum cleaner is used several times, it is necessary to dump the garbage inside as soon as possible, so as not to accumulate more and more and affect the suction power of the vacuum cleaner.

　　When customizing a car vacuum cleaner, you must choose the one you need correctly, and be careful in daily use in order to bring effective care to your car.
