A cordless battery vacuum cleaner was needed for the sailing boat. It had to be lightweight and not eat up much storage space. The hose of our old on-board vacuum cleaner alone took up as much space as a beverage crate. I was also fed up with tangled cables that wouldn't rewind. Enough of bumping a floor vacuum against table legs and edges. But are the battery and suction power enough? After half a year, I can say that the effort was worth it.
