Vacuum cleaner is a machine that was a creation of human intelligence that enables man to keep his surroundings clean with minimum effort. A carpet vacuum cleaner uses a motor that creates partial vacuum by using air pump to absorb dirt and dust from any surface. The dust accumulates in a dust bag which can be cleaned or disposed as per the technique that the machine supports.

The fiat manual vacuuming models were seen around 1860s where the similar mechanism of manual carpet cleaning was used with a motor. Next came the 鈥渨hirlwind鈥?principle where one had to crank up the motor to do the cleaning job. Bissell created a market niche with their product called 鈥淐arpet Sweeper.鈥?Thurman came up with 鈥減neumatic carpet renovator鈥?which offered horse drawn carriage with a motorised system of cleaning carpet way back in 1899. Booth used 鈥渋nternal combustion engine鈥?to run a vacuum cleaner. Later Hoover patented 鈥渞otating brush鈥?design. After Second World War when wall-to-wall carpeting became popular and the need for vacuuming was urgently felt and its sales increased.
A variety of designs and configurations have been offered for kinds of commercial and domestic vacuum carpet cleaner. The standing upright cleaners are common in North America and continental Europe. They come if two forms the older ones that use direct fan that are found in commercial machines and fan bypass is the newer version. Canister vacuums are cylindrical models used mostly in Europe. Drum vacuums are used in industrial versions. The wetdry vacuums are used to clean liquid spills. Pneumatic wet n dry vacuums use compressed air for both wet n dry clean ups. Hand held cleaners are lightweight ones with rechargeable batteries. Robotic cleaners are spherical motorised ones which work without manual supervision. Carpet cleaning is a task which may be a tough one for many. In case if you are not passionate about doing the cleaning yourself you can opt for getting the services such as Carpet cleaning Beverly Hills for getting the help.
Different mechanisms are used in the newer versions of carpet vacuum cleaner. Cyclonic vacuums use principle of dirt separation by central vacuums. It was first launched in Japan in 1980s at a very high cost , but subsequently it was a hot item. The filtration system uses cyclonic suction process to separate dirt in a vessel. Central cleaners use a different mechanism... They use cylinders with dirt filtration motor in a central location of a commercial building. The vacuum inlets are connected with pipes to the central dirt collection chamber. Hence the hose and cleaning head needs to the transported to the cleaning area instead of moving the bulky machine. The dirt bag is in a central bin to which the hoses are connected thereby making cleaning of commercial buildings easy.
