Before undertaking testing, The Hammacher Schlemmer Institute surveyed consumers to learn which attributes are most critical when purchasing a Cordless Handheld Vacuum. They responded that Cleaning Effectiveness is by far their most important concern, followed by Ease of Use, Run Time vs. Charge Time, and Features. These attribute rankings were applied to the data collected for this test.
Respondents were also asked which features matter most in a Cordless Handheld Vacuum. Based on their answers, The Best model must have the ability to work on hardwood flooring, ceramic tile, and low-pile carpet, the ability to pick up crumbs, lint, soil, and other typical household debris, strong suction, easy to empty debris container, and long battery life.
The Hammacher Schlemmer Institute then researched the marketplace from a reasonably wide range of competing product and obtained Cordless Handheld Vacuums that possess these desired attributes and features. Prior to testing, the Institute eliminated from consideration any models that did not have a required attribute or feature or if it had an obvious quality issue. Conversely, if a sample offered a unique benefit that distinguished it from other models, The Institute, at its discretion, may have included it in testing even though it may have been lacking a critical feature or attribute.
Testing involved evaluations by Institute analysts. Each Cordless Handheld Vacuum was rated for its Cleaning Effectiveness, Ease of Use, Run Time vs. Charge Time, and Features.
Analysts tested how well each model cleaned up different types of debris from three types of flooring-carpet, hardwood, and ceramic tile. Each debris type was laid out in a small pile, and the analyst noted the time each vacuum took to clean up the mess. Scores were awarded based on the time required in each category. At the end of testing, an average score was calculated for each vacuum.
For each model, Analysts considered how easy it was to:
Units were scored on a scale from 1-10 with 1 being "very difficult" and 10 being "very easy." Analysts then took the average of the scores and determined a final Ease of Use score.
For each Cordless Handheld Vacuum, analysts considered how long each vacuum ran compared to how many hours it took the battery to recharge. The batteries were run down to completely empty. The time to recharge to full capacity was noted. The Analysts then ran the vacuums noting the amount of time until the battery died. This test was run multiple times. The highest overall score was given to the vacuum with a battery that lasted the longest and recharged the fastest.
Institute analysts inspected each sample to determine whether it had any of the following features, which made a Cordless Handheld Vacuum easier or more effective to use:
Analysts awarded points for each feature that a model had, weighted according to how important that feature was to consumers. After testing, they calculated an average features score for each sample
The Hammacher Schlemmer Institute recommends that you consider these features when shopping for a Cordless Handheld Vacuum to ensure you will be completely satisfied with its performance:
For life's little messes, sometimes it's not worth hauling out your big vacuum cleaner. Instead, a handheld cordless vacuum can do the job in a matter of seconds. With the strong suction, you can pick up everything from salt to cereal on a range of flooring types, including hardwood, carpet, and tile-even the grout. Additional attachments help you clean crevices and furniture. When you're done, just empty the debris container and wash the filter. There are no messy bags to replace, and no tangled cords to get in your way while you work. Look for a long-lasting battery that recharges in just a few hours-so you'll be ready the next time you track in soil from the garden or your toddler flings breakfast onto the kitchen floor.
As with any product, customers must read and follow the product's user guide, marking and labeling prior to use.
