It is in the cable! Imagine that you are a night out with your plugin hybrid car, let’s say to a theatre. When you come back to your car you have to disconnect the cable. So, with your polished shoes and your best outfit you have to handle the cable that was on te street for houres. Any idea how many dogs came by to mark it? After disconnecting you have to roll it up and store it somewhere in the car. That gives dirty hands and clothes.
Now, back to the vacum cleaner. When you disconnect that you just have to push one button. The cable rolls up automaticly! That is brilliant, and that for a machine that costs less than the ashtray in a car! How hard can it be to adept this system in to a car?
