Dyson makes vacuum cleaners, not 'hoovers' :-)

Clearly no flies on you then, are there.?

There are because no domestic cleaners use a true vacuum (like in 'the
vacuum of space'), they use 'suction' that at best causes a pressure
drop / partial vacuum, along (often) with vibration / physical
aggravation (or even cleaning fluids). ;-)
