For many housewives, the vacuum cleaner reduced the fraction of time cleaning the house.  From the beginning,vacuum cleaners were only able to suck up dust and dirt, but with modern technology these days, inventors are able to design wet cleanes that can steam carpets and kill germs at the same time for more hygenic purpose.

Carpet are used to cover the floor of a house, flat, or bungalow and keeping feet warm during winter.  Years ago, people needed to sweep their floors or carpets, but with the invention of the vacuum cleaner, people could easily detract the dust and dirt from their carpets with less effort.  It was also determined that businesses, corporations, and apartments would need someone to clean their carpets as well, so the invention of the commercial carpet cleaner wasn't far away.

There are seven widely known main types of vacuum cleaners - the upright, canister, back pack style, built in, robotic, hand held, and the wet/dry vacuum cleaners. These different types of vacuum cleaners are available in a variety of different styles, sizes, and offer various voltage and power.

One of the most significant developments in vacuums is the invention of the cyclone carpet cleaner.  Unlike the previous vacuum cleaners, the cyclone collects dirt and dust in a large cylinder.  The cyclone operates using a central air force and number of filters. The filter will filter the dust and dirt into stages, so that the air being sucked up into the cylinder can be cleaned then released back into the air through a central outlet.
