Hovercraft Vacuum!

Okay, someone explain to me how an object that's so busy BLOWING (if I'm not mistaken a Hovercraft is able to 'float' by blowing out air to keep it up) is able to SUCK ?

 

[SuperFreaky]

I see your point... how does that work?

Maybe the inner area blows and the outer edge sucks?

 

[Ornery]

Ah-hah. Instead of blowing air out from under the boot around the perimeter, it blows it back up an orifice in the center. My guess anyway...

It's a canister vacuum that sucks like a normal vacuum but the canister itself doesn't have wheels and the exhaust is directed downward to make it feel lighter when it's on?

 

[Descartes]

Although I don't see quite how, perhaps its making use of the increase of fluid velocity from the blowing to exploit the Bernoulli Effect decreasing static pressure? Perhaps a physics pundit would have more insight.

This seems like a semi-good idea, except for one minor detail.. all the air it is blowing under itself will surely blow half the dust and dirt into the air, especially on a tile or wood floor.

I have the same problem with a handheld vac now - the suction is RIDICULOUS, but because of that, the amount of air it blows out is equally ridiculous... so unless you are using the hose attachment, half of whatever you are trying to suck up gets blown into the air.

Edit: I'm assuming that this is a normal canister vac with a hose that attaches to it - I don't think the hovering part does any of the sucking.
