Wireless is good, wireless is more convenient than wired, easy to operate and can also operate at will in the dead corner! The cable needs to be plugged into the cigarette lighter, and there is always a line hanging everywhere when cleaning the back, and the cable is not very convenient when it is put away. And the late line is also prone to rupture resulting in leakage and other problems. However, the car vacuum cleaner is affected by suction, and there will be a great lack of care, not very clean! Or use the hand-held vacuum cleaner at home to suck it!
Each has its own advantages. The general suction of wireless is relatively small, and it is more expensive but convenient. The general use time is not long. 20-30 minutes is long. The general suction of the cable is large and cheap.
