mostly made from sturdy cardboard with a few cheap metallic bits.
vacuum the house, remove the power lead and bin the rest.
look mum, no dirty hands.
comes in pack of three.

No need to keep the cord, use a built-in disposable battery like the iPhone has. |

// sturdy cardboard with a few cheap metallic bits // |
|
| |
"a few cheap metallic bits" is reasonable, but "sturdy cardboard" is very much at odds with the iPhone design philosophy. |
|
| |
No need for a power lead. Just make it large and sturdy
enough to enclose a substantial amount of vacuum, pre-
loaded at the factory. Place near dust. Release safety valve.
Bin. |

| |
Also handy for dealing with spiders and small children. |
|
| |
So you're asking for a cardboard Roomba??? |
|
| |
nothing so exotic - just your basic vacuum cleaner (well mebbe the dyson ball and cyclone thing if possible). |
|
| |
So what you're after is a power cable (and/or battery), motor and fan rotor onto which you clip the disposable cardboard bag/filter/nozzle unit. |
|
| |
I guess the problem you'd have is that to be effective the permanent bit would have to be of a quality to make it cost similarly to regular vacuums, but you've effectively got a regular 'bag' vacuum but with a floppy cardboard bit to try and suck your carpets. |
|
| |
Like a bagless cleaner, but with a bag to buy and worry about as well! |
|
| |
no, the only permanent piece is the cable but as someone said a battery would suffice (if it were powerful enough). |
|
| |
Motor = metal; for windings, pole pieces, shaft and bearings. It's going to cost quite a bit for a single use device. |
|
| |
However, a venturi tube driven by a pyrotechnic gas generator might work. |
|
| |
Isn't this what happens already, though?... albeit with a few years between purchase and disposal
In the olden-days, the only bit we'd keep would be the plug |
|
| |
//Motor = metal ... going to cost quite a bit for a single use

perhaps a central vacuum system. |
|
| |
in't that what "central vacuum" means ? |
|
| |
you make sure the seams are secure. if a cardboard pack can hold milk securely ... |
|
| |
True, but consider the mess made when trying to release the milk from the cardboard container! You would have vacuum all over the place! |
|
| |
Wouldn't a disposable house be a much more far-reaching
and effective solution? I believe cardboard houses are
already favoured by some sectors of society. |
|
| |
What Ian said, but with an additional set of plugs containing 'blow'. |
|
| |
missing the point [poc], the cardboard box + milk/dust would be thrown away. |
|
| |
hmmm, a wind up version to run a reverse bellows would take most of the metal/moving parts out of the equation...maybe a dual bellows for constant suction. |
|
| |
Powered by elastic bands ? |
|
| |
Apparently in the olden days, the first vacs were great bellow-operated things that servants pulled around on trolleys. You could still have the suction part (with all the moving parts) be permanent, and just supply a big hose, filter, bag and wheely thing all made out of paper or cardboard, or whatever, that you could just crumple up and throw in the bin when you'd finished.

powered by an aluminum-saltwater battery... mounted on a standard broom-handle. |
|
| |
Combined "central vacuum" source and exercise bike ? Pedal your way to fitness and cleanliness. |
|
| |
//Powered by elastic bands ?// |
|
| |
Nope. I picture sort of a hand cranked cross-bow. The bellows provide resistance to an internal rod's un-flexing.
On second thought, I'd lose the crank altogether and just use body weight to bend the whole handle for power. |
|
| |
It occurs to me that a refrigerator could be converted to a large upright vacuum / central vacuum without too many extra parts. |
|
| |
Maybe it could work by condensing air to a liquid, thus creating a region of reduced pressure. The liquid air would entrain the dust etc. sucked into the enclosure, and have the added advantage of freezing and killing dust mites, etc. |
|
| |
The liquid could then be pumped outside, where it would safely evaporate, leaving just the dust. |
|
| |
I'd go with z_t's 'blow' socket. Highly compressed air supplied by pipe to each house. Just release the cap on the socket and all the dust, junk mail, old furniture, unwanted relatives etc are just blown out of the house. Remember to open the windows first though. |
