Vacuum Cleaners - Types of Vacuum Cleaners

Vacuum Cleaner Types:

There are many different types of vacuum cleaners available today. You can save money on all of these if you spend a little time doing some research first. Upright, canister, wet vacs, back-pack, built-in or central vacuum cleaners, robotic, handheld, drum, electric and compressed air vacuum cleaners.

Upright vacuum cleaners have the pump mounted directly above the suction intake, with the bag mounted on the handle, which rises to about waist height. Upright designs usually employ mechanical beaters, often rotating brushes, to help disturb dust to be vacuumed up. There are two types of upright vacuums. On a single-motor upright, the beater brush is driven by the vacuum motor via belt, while on a dual motor upright, the vacuum and beater brush are driven by separate motors. The dual motor upright is very common in commercial uprights.

Canister (or cylinder) designs have the motor and bag in a separate canister unit (usually mounted on wheels) connected to the vacuum head by a flexible hose. Although upright units have been tested as more effective (mainly because of the beaters), the lighter, more maneuverable heads of canister models are popular. Some upmarket canister models have "power heads", which contain the same sort of mechanical beaters as in upright units, although such beaters are driven by a separate electric motor.

Wet vacs or wet/dry vacuums—a specialized form of the canister vacuum—can be used to clean up wet or liquid spills. They commonly can accommodate both wet and dry soilage; some are also equipped with a switch or exhaust port for reversing the airflow, a useful function for everything from clearing a clogged hose to blowing dust into a corner for easy collection.

Handheld vacuums can vacuum wet and dry. (depending on which vacuum)

Back-pack vacs are commonly used for commercial cleaning: they allow the user to move rapidly about a large area. They are essentially canister vacuum cleaners, except that straps are used to carry the canister unit on the user's back.

Built-in or central vacuum cleaners move the suction motor and bag to a central location in the building and provide vacuum inlets at strategic places throughout the building: only the hose and pickup head need be carried from room to room; and the hose is commonly 8 m (25 ft) long, allowing a large range of movement without changing vacuum inlets. Plastic piping connects the vacuum outlets to the central unit. The vacuum head may either be unpowered or have beaters operated by an electric motor or air-driven motor. The dirt bag in a central vacuum system is usually so large that emptying or changing needs to be done less often, perhaps once per year. The central unit usually stays in "stand-by", and is turned on by a flick on the handle of the hose. Such a unit also produces greater suction than common vacuum cleaners, because a larger fan and more powerful motor can be used when they are not required to be portable. Another benefit of a central vacuum system is that unlike a standard vacuum cleaner, which blows some of the dirt collected back into the room being cleaned (no matter how efficient its filtration), a central vacuum removes all the dirt collected to the central unit. Since this central unit is usually located outside the living area, no dust is recirculated back into the room being cleaned. In addition, because of the remote location of the motor unit, there is less noise in the room being cleaned than with a standard vacuum cleaner.

Robotic vacuum cleaners move autonomously, usually in a mostly chaotic pattern ('random bounce'). Some come back to a docking station to charge their batteries, and a few are able to empty their dust containers into the dock as well.

Small hand-held vacuum cleaners, either battery-operated , cordless, or electric, are also popular for cleaning up smaller spills.

Drum vacuums are used in commercial and industrial applications. With such a configuration, a vacuum "head" sits atop of an industrial drum, using it as the waste or recovery container.

Electric and Compressed Air powered models are common. Compressed air vacuums utilize the venturi effect. Manufacturers include Nortech Corporation and HafcoVac.

Most vacuum cleaners are supplied with various specialized attachments, tools, brushes and extension wands to allow them to reach otherwise inaccessible places or to be used for cleaning a variety of surfaces.

Name brands of vacuum cleaners include: Miele, Electrolux, Kirby, Dyson, Rainbow, Hoover, Oreck, Shark, Eureka, Royal, Panasonic, Dirt Devil, Kenmore, Bissell, Roomba and Fantom.
