I have a Kenmore DuraPower 37030 bagless upright vacuum cleaner for sale at Sears for $99. Its regular price is $199, but it often sells for less. It has a powerful 12 amp motor and came with the usual onboard tools and a 30 foot power cord. The warranty is one year on parts and labour.
I use the vacuum cleaner at my insurance company where we have carpeting. It has an electronic dirt sensor that detects how dirty the carpet is. That seemed like a gimmick, but it is actually useful to see which parts of the carpet need extra attention. It is very good to clean the carpet. It’s kind of satisfying to watch the sensor light show the dirt, then you see the brush spinning and the collected dirt swirling in the cyclone tank. Then the dirt sensor indicates clean and all is well! What will they think next?
Another feature is HEPA air filtration and the air is clean and not dusty when the machine is in operation. The vacuum cleaner is fairly quiet and feels good quality. The waste container is easy to empty.
So far the only negative factor I’ve found is that the vacuum is big and heavy. After cleaning about 800 feet of carpet it starts to get tiring. It doesn’t get under things like seats as easily as smaller machines. I wouldn’t want to carry it up and down often.
Overall, I am very satisfied with the DuraPower 37030.
