John,
I couldn't agree more...stop fixing something that is not broken.
Look at Kirby and Aerus, other than some minor body changes they still have some of best vacuums on the market...and still use bags...what a novel IDEA! Or how about the Sainitaire Upright...still will out clean almost anything on the market..old design...great product. Not to mention only a 6 or 7 amp motor...same with Kirby!
In a few years, they will change the design back to bagged and call it a new idea...
Look at Hoover in the early years...it made no difference which convertible you purchased, they would all clean the same because they used the same motor and brush roll...the only changes were bumper, cord length, handle grip and headlight...yet they had the consumer fooled that one machine cleaned better than the other....mind over matter...it cost more...so it must be better!
Same way I feel about many of the new machines, especially bagless...just because it has a clear bin and you can see the dirt, doesn't mean it is cleaning any better. Remember Lewyt and the bags with the dirt window so you could see how full the bag was without removing it.
