I've heard them called stoor sookers...

[<me9]

They're called hovers on our local freecycle.

Ours was always called an Electrolux, even when it wasn't.

That sucks.

I doubt you'd say that to her face and live...;-)

My 'workshop' one is a Rowenta wet or dry, again a Which best buy, and that is still great. Have to search a bit for the bags, though. It's even older than the Panasonic.

eye.

Being named after a DEC computer is an added bonus.

[Albert Ross]

Yes, uprights were Hoovers, cylinder cleaners were Electroluxes.

True or apocryphal I don't know, but at a demonstration of a suction/vacuum roadsweeper it allegedly sucked a dog off its lead

My Vax needs a new bag and filters, when it's on song it will lift the carpet and pull out parquet blocks

[Frank Erskine]

I always admired the Hoover Constellation for its idea. I don't know whether they actually worked though :-)

[John Williamson]

Only on hard floors, and then only until the rim got damaged.

I've just invented a new kind of vacuum cleaner that uses no energy. Just attach one end of a very long tube to a satellite in geostationary orbit, with the other end dangling down to Earth. There's a stopper in the bottom end which you remove to suck up all the dust into space.

If space elevators [

] work, why not this?

[Peter Duncanson]

It will work nicely until the pressure in the tube equals the pressure outside the tube. Then it will stop sucking. After that you would need to pull the tube up into space, empty it, put the stopper back in and lower the end back to the surface.

Unfortunately, both the dangling sucker and the space elevator require energy for their construction and use.

[Nick Odell]

Bit of a bugger to sort through when, inevitably, you suck up that missing SD card or diamond ear stud.

A tube to space won't suck air up. Gravity would hold the air in the tube down, just like it does the rest of the air.

[Richard Tobin]

Nothing sucks like a VAX, as they never actually said.

Perhaps you should run it in conjunction with one of these:

[Peter Duncanson]

The tube starts empty by being out of the atmosphere. A stopper is put in one end which is them lowered to the Earth's surface. When the stopper is removed air and small objects rush in.

This reminds me of a thread crossposted to a farming newsgroup. The OP was suggesting a means of generating electricity by harnessing the difference in water pressure between the surface of the sea and several kilometres down. I showed him the problem with this by describing a way of doing the job analogous to the long dangly vacuum cleaner tube above. A tube with turbine and generator at one end would have a closed valve at the inlet to the turbine. The turbine end would be lowered to the seabed. The valve would be opened and water would rush through the turbine generating electricity lots of nice electricity ... until the tube was full. The person in charge should then go somewhere quiet and do an expenditure and income analysis for both money and energy.
