I bought this vacuum about a year and a half ago. Worked great for a few months, then the power brush for the carpet stopped working, it turned out to be the belt needed replacing. Also the "carpet/floor" switch got really hard to operate, and then it got kind of floppy like it wouldn't stay in position. So it worked okay for a few more months, then the same thing happened with the power brush. So I replaced the belt again. This time it didn't work even after I replaced the belt. I believe the carpet/floor switch is completely broken and that is why it won't work.
