Vacuum cleaners
In many developed countries, vacuum cleaners are used as the preferred
cleaning tool. Homes in these countries have wall to wall carpeting
which cannot be cleaned conveniently
Using electricity, a
vacuum is generated by the air pump in the vacuum cleaner which
attracts the dust and other foreign particles from the carpet and other
surfaces.
After a while, the accumulated dust has to be removed from the bag and the process is repeated.
