I really need to know how a vacuum cleaner works. Its for my science project. Please help me!
A vacuum cleaner works by creating a vacuum inside the air chamber. The mechanical / electrical part is really a strong motor that blows air, usually out the top or back of the vacuum, which creates a suction force at the bottom (where the dirt gets pulled inside).
The all work the same in principal....if you attached a motor that blew air (say a fan) to one end of an object that had an opening at the other side, it would work the same and cause air to flow first inside the object, then out through the fan.
I've never tried this, but look at the Dyson website. It'll probably tell you how ordanary vaccum cleaners work, and how the Dyson is different. Your project could branch off into two different... branches... hope this helps.
I use a central vacuum cleaner. You can read how it works in the article . The vacuum cleaner is very convenient and cleans all rooms even in the most hard-to-reach places.
something spins round inside it and then it sucks bits upp of the floor Lool its not 2 hard is it ? :L
search it in google lol
