Pay attention to the price ranges that each of these vacuum cleaner companies offers. Bissell, for example, has models between $40 and $270 and Eureka offers models between $50 and $200. Hoover can get a bit pricier with a range from $50 to $300.
Research the different types of vacuum cleaners so you know what you're looking for when you compare models. Upright vacuum cleaners are a popular, powerful option that clean well but are heavy and make a lot of noise. Canisters are even heavier and don't clean quite as well as uprights, but they are more versatile, moving from carpets to bare floors with ease. Central vacuums come with ease of use, but are tough to move and store. Stick vacuums are best for bare floors, but do not boast power or deep cleaning abilities.
Find out what each vacuum cleaner brand is known for. Hoover, for example, is known for uprights that provide deep cleaning, as well as canister vacuums. Stick models and central vacuums are also available. Eureka is also known for uprights and canisters, and sells other types of vacuums as well. Bissell provides uprights that help reduce allergens in the home, as well as other vacuum cleaner types, such as canister and stick vacuum cleaners.
Check the weight of the vacuum cleaner models you like the best. This information can be included in the product description, or if possible, you can test the weight at a retail location. The lighter the vacuum, the easier it will be to push and carry up and down stairs.
