Now that you know which type of vacuum you need, here's a list of features that are important to look at before you begin to compare brands.
Bag Type While many models still use bags, newer models are coming out with a bagless option. The bagless models are easier on your wallet (no need to purchase bags) and easier to empty (simply remove the dust cup).
Belt Type Your vacuum’s belt connects its motor to its brush system, causing the brushes to rotate rapidly to beat up debris. It's important to know the belt type of the model you choose because as time goes on, the belt will eventually need replacing, and you'll need to know exactly what belt type to look for.
Brush System The heart of a deep cleaner. Each model features one or several rotating brushes that scrub the water and soap onto the carpet. Brush-cleaning technology tends to be brand-specific. In fact, one brand will typically outfit several different models with the same technology.
Built-in Heater Many deep cleaners today offer "heat" switches that, when activated, automatically warm the water. This, in turn, creates more efficient cleaning.
Cleaning Path The width of the cleaning path is important because vacuums with larger cleaning paths tend to catch more dust and dirt faster.
Filtration Some filtration systems can remove up to 100% of dust mites from floors and furniture, which can help in reducing allergic reactions caused by dust.
Headlight Vacuums with a headlight allow you to see any objects obstructing the cleaning path. The headlight especially comes in handy while vacuuming hidden or dark areas, like under the bed or in the closet.
Height Height settings are what make certain types of vacuums so versatile. The more height settings that are available, the more surfaces your vacuum can clean. Go from a throw rug to bare floors in the flick of a switch!
Motor The more suction power your vacuum has can greatly reduce the time and effort you put into vacuuming your home. Amps, watts and volts are how vacuum power is measured. The greater the suction power, the cleaner your floors will become.
Onboard Tools Crevice tool, upholstery brush, deluxe hoses ... these little goodies can make big differences in cleaning! Almost all vacuums and deep cleaners include one or more tools to reach corners, stairs and other small places.
Tank Capacity The bigger the tank, the longer your deep cleaner runs without needing a refill of water. Like the models themselves, capacities vary, but the standard is around one gallon.
