I bet I'm the only one who, reading the title of this thread, thought it had something to do with physics.

It does, my Dyson doesn't work by chemistry, neither does any directly competing cleaning device.

Mine sucks.. like Gravity. And Magnets.

Hungyhorace - not picking on you personally but you really should stick to things you know about, and volts, amps and watts is apparently not one of them....
US voltage is notionally 120VAC, 60Hz
A step-up transformer for 2000 Watts of power is a big, heavy and hot beast. I have one to run some power tools and it is not luggable in any reasonable sense of the word
You will not get more that about 1800 Watts out of a US 15 amp wall socket. Some rings in the kitchen MAY be on a 20A circuit.
Finally the 50Hz UK frequency and 60Hz US frequency may have some effect on the performance of the vacuum, even if it is running at the correct voltage

OP - If you are adventurous you might be able to extract 220V from a wall socket in the kitchen or garage (with a lot of caveats). Since you asked the question it is probably safe to assume this is beyond you. As others have said, sell and buy one when you get here. We have the Animal (DC-07, sorry not sure of the exact model as it is the Mrs dept.) and it works.

No, no, i'll give you that one

Ours is about to hit 10 years old and still just as good too. Bit of a faff cleaning the front roller bit as it tends to get long hairs building up and remembering to rinse out the blue foam filter, but that's just a air filter for the motor.

They've certainly gotten lighter and more nimble over the years though.

Unlike me.

Might I suggest reducing the serving size of Devil Dogs to "six"?

Well, I don't see how that would work at all.

Use the Dyson to suck it out of you...there's probably a nasty picture in that one :/

JG would ban me.

This one, perhaps?

Magnets don't suck. Magnets are cool. I like magnets. What's your problem?

Gravity not so much. Its a bit like inflation....It just seems to keep increasing. i know, because every morning when I stand on that thing under my sink, I can tell gravity has gone up again. Not a lot, but like compound interest, the cumulative effect over a few years is quite remarkable.

Now will someone please tell me how much the ambulance cost cos I really need to go to sleep!

I had a Dyson DC07 years ago and reckon that they are overpriced and overrated.

The suction was good but otherwise the thing was a nightmare to use - it was clumsy and difficult to reconfigure and had a tendency to topple over when using the flexible hose with the "wand". To add insult to injury it didn't even have a retractable power cord.

I ended up buying a canister vac from Sears for less than half of what the Dyson cost and have been perfectly happy with it for the last 6 years.

Magnets do so too suck, but in a cool way.
The earth has magnets in it (you can dig em up, I saw it on tv). All the magnets in the ground are why we don't all fall off of it. Without them, places like Australia wouldn't work at all!!1!

Gravity, well, you can't mess with that, it's the Law.
