How to Rate Vacuum Sweepers

Determine the power of the cleaner. Vacuum cleaners are often rated by amps which tell less about the cleaning power of the vacuum than it tells how much energy the cleaner uses. Check the information in the manual or other literature that lists the airflow. Airflow is commonly expressed in CFM, cubic feet per minute. CFM tells how much airflow is passed through the cleaner and gives the most accurate accounting of a vacuum's cleaning power.

Calculate the cost of operating the vacuum. Bagless vacuum cleaners do not come with the cost of replacing dirt collection bags. They do require regular maintenance and periodical replacement of the cleaner's filters. For ease of use, bagless vacuums may prove desirable with no bags to buy or change. You will need to more frequently empty the collection bin, a step you may have to take in the middle of heavy cleaning. Evaluate your preference here.

Choose the vacuum with the best filtering capability especially if you or someone in your household has issues with allergies. Bagged cleaners and bagless models are available with filtration systems that are effective in keeping dust and dirt inside the collection container. Some machines perform better than others. Choose the filtration system rated to capture the smallest particles possible to ensure the debris sucked into the vacuum is not exhausted into the air while you are cleaning.

Take into consideration the amount of dust that is released into the air while you are emptying the bagless collection bin. Though bagless vacuums are commonly equipped with an array of filters, nothing holds the dust in the bin while you are emptying it between cleanings.

Consider the number of attachments and the cleaning radius of the models you are evaluating. Canister vacuums are designed for using attachments to clean various parts of your home or office, however, upright vacuums often come with a hose and attachments to clean above-the-floor. The cleaning radius of a vacuum explains the distance you can clean while the cleaner is in a fixed position. A cleaner that has the ability to clean the top of your steps while the main unit is still at the bottom of the stairs is more convenient. Note: the farther the cleaning head is from the motor, the less the airflow at the head.

Consider the cost of the vacuum and the manufacturer's warranty covering the cleaner. Plastic vacuum cleaners are often replaced or refurbished within 10 years of purchase. Metal vacuum cleaners (Kirby, commercial brands and models) last generally longer. Consider the overall cost to own and operate the cleaner. Take into account the cost to replace filters and/or bags as well as the energy expense of varying models.
