Thanks Huskyvacs,
I figured he didn't know a great deal, when he says he doesn't understand why it works in the same direction when he switches polarity.
I can't practically run an extension cord from home to car.
So I was thinking of an Inverter and a USA 120v vac. Like a Royal 501. Presuming a 120v Inverter may offer better Amperage than 240v? That's when I found his video clip.
The 12v car vacs I've seen are little more than dolls-house toys. Most secondhand ones have only ever been used once or twice. With good reason. I've often thought a built-in vacuum for cars wouldn't go amiss. Perhaps with engine running? They do built-in tyre inflators now, apparently.
I guess I'll go for some sort of rechargeable small domestic, battery-operated.
Could you please expand details of your industrial Clarke power sander vacuum?
Alan
