I bought this expecting it to fit my Shark vacuum. It's not like this. However, I am so impressed with its design and the fact that the seller sent two microfiber pads that I decided to try my full size canister. It works! This is a very good tool for my wooden blinds and cuts the work in half. I highly recommend! The only reason I gave it 4 stars instead of 5 is that I wish there was a mount that would allow me to use it with my shark!
