I just used my new carpet sweepa and wow was I impressed! I had an old carpet sweeper from probably 25 yrs ago that I was using, but it only picked up part of the dirt, no matter how many times I went over it.
I have a long carpet runner down my hallway which would get coated with fur from my long haired cat. The hair clung tightly to the carpet and would not come up. Then I tried my new carpet sweeper and it all came up.
It has not looked this clean in a long time. Also, it picked up cat litter from my bare floor, something my old sweeper left.
Just had to let you know how pleased I am. You can use my testimonial if you wish.
