Kenmore 25914 / 25915 Progressive Bagged Canister Vacuum Review

I own a cleaning business and have 7 Kenmore Progressive vacuums. We provide routine household cleaning, commercial cleaning, and post construction cleaning.  I purchased my first one 4 years ago and the last 2 this past year.  I also purchased a Riccar vacuum this year since I was having problems with the electrical components on the Kenmore.  After using the Riccar, which was significantly more expensive, I have decided to repair my Kenmores.  I have had clients comment on how well it worked and have even purchased them for in between cleanings.  My staff think it's the best vacuum they have ever used.  We use them to theirfullest and the only negative I have is the electrical portion in the "wand."  However, I admit that we do not always shut the machine off when switching attachment's and so are partially at fault for this.  The first one I purchased has been used on average 10 hours a week for 4 years, is hauled in and out of homes every day and not always by the most gentle hands, and is still running well.  I believe that if you purchase a Kenmore Progressive and use it for normal household use you will never buy another vacuum.
