Bag change indicator—A light that comes on automatically when it is time to change the bag and helps the vacuum operate with maximum efficiency.
Bagless—Bagless models reduce the cost of purchasing new bags and are easier to empty by simply removing the dust cup.
Belt—The vacuum belt connects the motor to the brush system. This causes the brushes to rotate rapidly and process debris. It's important to know the belt type of the model you choose in the case of a replacement.
Brush System—This is the heart of a deep cleaner. Each model features one or more rotating brushes that scrub water and soap onto the carpet.
Built-in Heater—Many deep cleaners offer heat switches that automatically warm the water. This helps to create more efficient surface cleaning.
Cordless—These vacuums are typically lightweight and give you a wide range of mobility when cleaning your floors. Included docking stations provide a quick charge.
Cleaning Path—The width of a vacuum and ability to capture dirt and dust; Vacuums with a larger cleaning path capture a great amount of dirt and at a faster rate.
Crevice tool—A long, angled attachment that cleans detailed, hard-to-reach places, like corners.
Dusting brush—A bristled brush attachment for dusting hard surfaces.
Edge cleaner—This feature can pick up dirt under the entire area of the cleaning head for wall-to-wall carpeting.
Filtration—Filtration systems help remove dust mites from floors and furniture. This is ideal for reducing household allergens.
Headlight—Vacuums with a headlight allow you to see objects obstructing the cleaning path in dark spaces (closets or under the bed).
Carpet-height adjustment—This feature changes the height of the vacuum's brush roll to the carpet height for easy maneuvering.
Motor—The more suction power your vacuum, the less time and effort it will take to clean your floors. Vacuum power is measured in amps, watts and volts.
Motor protection system—This protects a vacuum's motor from overheating, especially when there is a jam or blockage.
Onboard Tools—Crevice tools, upholstery brushes and deluxe hoses are just a few that can make a big difference when cleaning! Many vacuums and deep cleaners include one or more tools to reach corners, stairs and other small places.
Pet brush—A bristled brush attachment used to remove pet hair and dander from furniture, stairs or other small spaces.
Retractable cord—This is a common feature in canister vacuums where the cord winds into the machine for easy maneuvering and storage.
Self-propelled motor—A feature that propels the vacuum on its own for easy maneuvering.
Tank Capacity—The bigger the tank, the longer your deep cleaner runs without needing a water refill. Like the models themselves, capacities vary, but the standard is around one gallon.
Upholstery tool—A bristled brush attachment used for cleaning furniture, curtains or other fabric surfaces.
