How do I Interpret Vacuum Cleaner Ratings?

Vacuum cleaner ratings are generally based in part on laboratory testing and subjective consumer opinion relating to the various features and functions of the particular model. Vacuum cleaner reviews often compare design, proficiency, durability, maintenance requirements and warranty length to overall cost. Consumers typically choose a trustworthy brand of vacuum cleaner with specific features that is priced to fit within a household budget.

Ratings for canister vacuum cleaners generally include design and performance considerations. Some canisters weigh as little as 10 pounds while others may easily exceed 15 pounds, which is a factor to consider if you have to tote the machine up and down stairs or in and out of the house. Certain canister models contain a motorized power head, though others do not, which is a consideration for effective cleaning on deep carpets. Canister models often vary in suction power depending on motor design and efficiency. Various vacuum cleaner rating sites include different vacuum cleaner models and types along with a suggested price for comparison.

Some other factors apply when reviewing ratings for upright vacuum cleaners. These vacuum cleaner ratings generally include portability, suction consistency and power, along with price. While some models contain self-propelling features, allowing greater maneuverability, this bonus function also adds weight to the vacuum cleaner. Other elements to consider include the ease of adjusting the vacuum to various floor types and the ease of interchanging the attachments. Overall, ratings for bagless vacuums tend to be very similar to bagged uprights.

While emptying the dirt cup appeals to some people more than the price of having to replace bags, bags may be more hygienic because they allow fewer dust particles to become airborne. Additionally, bagless models usually contain some type of filter that requires brushing, washing or replacement. The convenience of bagless versions includes the ability to retrieve accidentally vacuumed objects.

Looking at vacuum cleaner ratings overall, consider the bag type, cord length, durability and whether or not they contain a high efficiency particulate air (HEPA) filter. Microfilter bags typically offer greater efficiency than traditional paper bags because they not only capture more dirt and dust, but also prevent particles from escaping back into the air. Most consumers prefer the cord to be at least 30 feet (9.14 m) long for convenience. Models with longer warranties are generally the most durable. Increasingly, manufacturers design bagged and bagless vacuums with HEPA filters, but not all filters are alike.

HEPA filter ratings determine whether the product is an absolute or true HEPA filter instead of a HEPA-type filter. True HEPA filters generally have serial numbers on the filter or the packaging stating that the product is capable of trapping 99.9% of particles that are 0.3 microns and larger. This design feature, though more expensive, typically ensures better air quality for those concerned about allergies and asthma. HEPA-type filters only trap approximately 85%-90% of these particles, and this percentage usually decreases with larger particles.
