When looking for a standard upright vacuum model, try lifting it with one hand. If the vacuum feels heavy or bulky, you may have difficulty transporting it up and down your stairs.
Handheld vacuums provide portable cleaning power, but cordless models need frequent recharging. Canister and upright vacuums provide strong suction power but weigh more than other designs. Central vacuum systems eliminate the need to tote around a bulky vacuum, but you must have space to store the hose attachment. Stick vacuums weigh less than canister and upright models, but don't offer strong suction power, according to ConsumerReports.org.
A vacuum cleaner that comes with an attachment hose allows you to clean hard to reach areas, like behind bookcases and under kitchen appliances. Vacuum cleaners with upholstery attachments allow you to clean your couch and curtains.
If a family member suffers from indoor allergies, consider purchasing a vacuum cleaner with an allergen filter. Allergen filters are designed to reduce the amount of dust and dander present in your home.
