Electric Power Brushes have More Air Flow, Less Moving Parts. The biggest difference between air driven brushes and electric brushes is the air opening size. How much air passes through the brush to the carpet is very important for cleaning. Air powered brushes, such as the Turbocat or Turbo Cat Zoom (or ANY brush that looks like them), have 4 times less air flow than an electric power brush (5/8 inch opening compared to 1-1/4 inch). The air powered brush requires a smaller opening to force air to spin a turbine and roller brush, but it means that less air and debris are able to pass through and consequently, less suction reaches the floor. Also, everything vacuumed up in an air driven brush is passed through the turbine fan blades, meaning that larger items can jam or even break the turbine. Electric brushes have a non-restrictive air passage, so more objects (including items like quarters and popcorn) are able to pass through without stopping or hurting a thing.
The Electric Advantage for Your Kenmore Vacuum. No matter how weak or strong your suction is, an electric brush will always have top performance because it is not relying on the air to spin it. Price is also a difference. While air driven brushes cost less, carpet is usually one of the largest investments homeowners make, making the up-front cost difference of an electric kit easily justifiable. Electric brushes are typically quieter and provide more consistent, deep cleaning because they are operated with an independent electric motor. On top of that, Stealth takes electric cleaning abilities even further with superior edge cleaning, 12 height adjustments, and lifetime belt warranty. If you want to upgrade to an electric brush you will also need an electric 110 volt hose as well. The most compatible and cost effective way to upgrade is buying a compatible Electric Kit for your Kenmore. Choose Attachment Kits in the menu.
