All vacuums can be divided by several basic types of design. Canister vacuums are so named because their design is similar to a water canister (container with handle) and they have a long hose that allows for extra reach. Upright style vacuums are vertically standing vacuums, where the entire device is pushed over the carpet or floor. Stick vacuums look like stream-lined uprights. This design lacks the power of an upright or canister model, but they are good for small living quarters. Handheld vacuums are small, compact and lightweight and come with a narrow nozzle. They are good for general clean ups but lack the power for bigger cleaning jobs. Wearable or "backpack" models come with a shoulder strap or harness and can be carried around the house by the user. Robotic models are the newest type and are somewhat of a novelty. These vacuums roam around a floor space on their own. Central systems are a stationary type of canister vacuum cleaner which is usually mounted in the basement or garage. This design has a single powerful vacuum with pipe system outlets for every room in a house.\r\n
Bag Filtration filters by having the dirty air pass through a disposable bag. The bag works much like a filter, removing the dust and dirt particles as the air passes though. Once the bag is full it can be emptied, or in most case replaced. \r\n Wet/Dry dirty air enters the tank, its speed decreases and dirt is falling down. \r\n Cyclonic systems separate the dust particles from the air flow by spinning the air within a chamber. The spinning causes centrifugal force to act upon the dust particles, separating it from the inner part of the chamber. Some cleaners use multiple chambers and most cleaners add filters to increase the total system filtration efficiency. \r\n Wet/Dry are almost exclusively cylinder in design and will work dry like a traditional vacuum but with the additional option of cleaning with fluid like water with carpet shampoo.\r\n

The filtration system for vacuum cleaners varies between machines. Most better quality vacuums today use a filter system so that dust and allergens that are sucked into the vacuum aren't put back into the air. Machines that use a bag to collect dust have no filtration while others are sophisticated enough to filter out pollen and particles less that 100 microns. Certain models have a HEPA (High Efficiency Particulate Arresting) filter, which operates at a higher efficiency rate and removes the smallest particles. More than one type of filter may be used in some of these systems, increasing their effectiveness. These units generally cost more but are very effective in reducing allergen in your home.
