Most homes that have<br /> <br /> carpet floors have a vacuum for cleaning. The dirt<br /> <br /> that is pulled up from the carpet is collected by<br /> <br /> a filtering system or even a cyclone for later<br /> <br /> disposal.<br /> <br /> There are several type of configurations possible<br /> <br /> for vacuum cleaners.<br /> <br /> Upright<br /> <br /> Upright vacuums have the pump mounted directly above<br /> <br /> the suction intake, with the bag mounted directly on<br /> <br /> the handle, which will rise to waist height or so.<br /> <br /> The upright type designs normally employ mechanical<br /> <br /> beaters which often rotate brushes, to help disturb<br /> <br /> dust enough to be vacuumed up. These beaters are<br /> <br /> normally driven by a belt that is attached to the<br /> <br /> vacuum motor.<br /> <br /> Canister<br /> <br /> Also known as cylinder vacuums, the canister type<br /> <br /> designs have the motor and bag in a seperate canister<br /> <br /> unit that connects to the vacuum head by a flexible<br /> <br /> hose. Even though upright units have been tested<br /> <br /> as being more effective, the lighter and more<br /> <br /> maneuverable heads of the canister models are quite<br /> <br /> popular. Some models have power heads, which contain<br /> <br /> the same type of mechanical beaters found it upright<br /> <br /> units, although they are driven by a seperate electric<br /> <br /> motor.<br /> <br /> Wet vacs/dry vacs<br /> <br /> These types a specialized form of the canister<br /> <br /> vacuum and they can be used to clean up wet or liquid<br /> <br /> spills as well. They will commonly accomodate both<br /> <br /> wet and dry soilage, with some being equipped with<br /> <br /> a switch or exhaust port that reverses the flow of<br /> <br /> air. This is a very useful function for everything<br /> <br /> from clearing clogged hoses to blowing dust into a<br /> <br /> corner for easy collecting.<br /> <br /> Back pack vac<br /> <br /> These types of vacuums are commonly used for<br /> <br /> commercial cleaning, as they allow you to move about<br /> <br /> quickly and efficiently in a large area. They are<br /> <br /> basically canister vacuum cleaners, except for the<br /> <br /> fact that straps are used to carry the canister<br /> <br /> on your back.<br /> <br /> Built in or central<br /> <br /> These types of vacuum cleaners will move the suction<br /> <br /> motor and bag to a central location in the building<br /> <br /> and provide vacuum inlets at strategic places<br /> <br /> throughout the entire building. You only need to<br /> <br /> carry the hose and pickup head from room to room,<br /> <br /> while the hose is normally 25 foot long and allows<br /> <br /> a large range of movement without changing vacuum<br /> <br /> inlets.<br /> <br /> The plastic piping will connect vacuum inlets to<br /> <br /> the central unit. The vacuum can either be unpowered<br /> <br /> or have beaters that are operated by an electric<br /> <br /> motor or an air driven motor. The bag in the<br /> <br /> central vacuum system is normally so big that<br /> <br /> emptying it or changing needs to be done less as<br /> <br /> often, sometimes only once a year.<br /> <br /> PPPPP<br /> <br /> (word count 459) [http://steviapedia.com/wiki/index.php?title=ClemenceEvans335 1.63 1]</div>
