Article by Jim Cherry
Removing dust and dirt from the surroundings is vital in possessing a healthy life. An absolutely clean atmosphere can protect from mild as well as hazardous diseases. There are lots of people who suffer from dust allergies, asthma and other breathing problems. A good amount of such complications can be avoided with the adoption of proper cleaning methods. The role of vacuum cleaners in such situations is crucial. It is a device used for sucking up the dust particles with an air pump. Run by either electricity or batteries, the equipment collects dust from floor and other surfaces into a dust bag.
Vacuum cleaners are available in different shapes and models. The price of each kind varies with the extra features. The basic theory of working is with variations in vacuum pressure. There is an electric fan inside the equipment that lessens the pressure. At that time, the air pressure thrusts air over the carpet and nozzle, and thereby dust is passed to the bag. The equipment essentially includes certain supplementary tools. There will be a hard floor or carpeted floor brush, dusting brush, upholstery and cranny tools generally. These accessories help in the cleaning of dirt at places that are often inaccessible otherwise.
There are plenty of varieties for this cleaning device and may include upright, drum, cylinder, wet or dry, handheld, robotic, pneumatic, central, cyclonic etc. The upright type is the common variety with a cleaning head, handle and bags with the use of rotating brush. These can be either direct air type or dry fan type. Drum type cleaners are widely used for industrial purpose. It has a characteristic drum attached. The cylindrical model is commonly used for house hold purposes. Wet or dry cleaners can fall in either of these two categories. It can also be pneumatic type. Cyclonic, central and the robotic are recent versions that offer highly effective cleaning.
The parameter specification for the working of vacuum cleaners includes the flow and speed of the air, suction, power, noise, input and output power etc. It is estimated that the power of the cleaner increases with increase in suction rate. A distinctive value of 80 inches is apt. The average input power rate is often calculated by the customer by multiplying line voltage with the current value expressed in ampere. The output power relies in the conversion of input power to air flow at the hose end.
