Vacuum cleaner reviews at VacuumWizard.com are done by completing a series of tests and measurements with each vacuum we test. We want to make sure we test each vacuum in a variety of situations.
Our first series of tests always involve how well the vacuum cleans carpeting and rugs. Because it is easy to see, and it is the same size as dust particles, we toss white flour onto the carpet for our first test. This enables us to see if the vacuum cleans up dust and fine particles with one pass, or if it takes some extra effort to get the carpet or rug clean. We also test the vacuum with larger particles. We use a variety of things such as crushed crackers, rice, or even pine needles to see how well large particles are removed from the carpet.
Our next series of tests involve using the same particles, but we use them on hard flooring. We need to see if the vacuum can suck up fine particles off the floor as well as larger particles. We also put these particles up against the edge of the floor to see if it can get the edge clean without the use of an on board tool.
The on board tools on a vacuum are very important, because they allow you to clean in a variety of situations. We test how easy it is to access these tools, and also if these tools do a good job cleaning up small spaces, on stairs, and on upholstery.
No vacuum cleaner review would be complete without testing each vacuum with a decibel meter, an airborne laser particle scanner, and with a suction gauge. The decibel reader measures how loud a vacuum is when it is in operation.
The laser particle scanner tests the filtration system, and the suction gauge measures the inches of water lift, which means how powerful is the suction on the vacuum cleaner.
Maintenance and recurring costs are important elements to consider when purchasing a vacuum. For bagged vacuums, we see how large they are, and how easy or difficult it is to take them out and put them back in.
For bagless vacuums, we test how easy or difficult it is to take the dust bin off the vacuum, and if it is a messy process to empty it into the garbage.
Vacuums also have filters that either need to be washed or replaced after so many hours of use. We test how hard it is to take these filters out and show how you have to clean them in order for the vacuum to continue to operate properly.
