Wireless utility. Because the wired version should be connected to the cigarette lighter, if the product quality is defective, it is easy to break the cigarette lighter interface, and even make the vehicle insurance short circuit. At the same time, the wired version is easy to trip people, the wire is easy to damage, and it is inconvenient to carry. The wireless version is lithium-ion battery, charging fast capacity, hand-held car wash without bondage, water pressure is also large. I am the new wireless version of the car wash machine, feeling very good effect.
Wired, the motor is strong, wireless convenience, depending on the personal use
