Kenmore Elite 31150 Vacuum Cleaner Review
This Elite is actually pretty accessible
By the Numbers
All vacuum testing takes place in a sealed room, so only the contaminants inside are our testing materials.
For all performance tests, we use a 90-gram mixture of dirt made of particles of varying size, from coarse sand to talcum powder. This mixture is placed on three surfaces: shag carpet, normal carpet, and bare floor. We also use uncooked macaroni and rice to simulate large debris, and cat hair to simulate a pet living in your home. After the test run is complete, we weigh the bag or canister to determine how much dirt has been cleaned up.
We measure the loudness of each vacuum in a sound-proof chamber, gathering measurements from 10 feet away. The Kenmore Elite 31150 is quite loud at 74.2 dBA.
Edge Cleaning & Furniture Clearance
We place wooden obstacles on the testing surfaces to simulate corners and furniture. The 31150 had perfect edge cleaning abilities, picking up just as much dirt against a wall as it would have in the center of a room.
Unfortunately, the 31150's bulky form prevents it from reaching under furniture. Given four-inches of vertical clearance, the bulky 31150 could only reach 6 inches underneath a couch. In fact, even given a full foot of clearance it could only achieve 19 inches of reach. That's the curse of thicker upright vacuums.
The Kenmore Elite 31150 did well on both normal and shag carpet. On average it picked up 24.85 grams of dirt per test run. Which means it would take about three passes to get your shag clean. On normal carpet, the 31150 picked up 74.8 grams per test run, meaning only two passes over the same area would be necessary to remove all the dirt.
Bare Floor Cleaning
The bare floor test consists of only of rice, macaroni, and cat hair. The Elite performed almost perfectly: removing all of the hair and macaroni, but missing a single grain of rice.
