Does a vacuum cleaner work in space?

Does a vacuum cleaner work in space?

 

No. First of all it wouldn't stay on the ground. and why would you need to vacuum?
A vacuum cleaner depends on a difference in air pressure to operate. With no air pressure in space, there could be no difference in air pressure and thus no operation.

Inside a manned spacecraft, which is usually pressurized a vacuum cleaner will obviously work just fine; especially for collecting and disposing of water globules. Also the standard NASA space toilet uses a modification of a vacuum cleaner for urine collection.
