I have used Kenmores for years, for the price, they are great. I also have a Dyson... it is great for some surfaces, but a lot of dust escapes from the bagless cannister. Now I own a Rainbow. in a class of its own, this beast is a workhorse. I did add some skinny wire shower hooks to the top of it so I could caddy around the attachments (round brush, narrow space suction, upholstery brush) by just hooking the attachments through the open shower hooks. Works great. It cleans totally clean, does not release dust into the air, and you can add scents to the water to give yourself a scented working environment as well as temporary nice smell to your home.  I do, however, hate throwing out the water with all the hair, dust, fur, threads, and other material I have vacuumed up. You have to clean the tank (just empty and rinse) each time you use it or it will STINK!
