I have a question for you all. I have a Hoover convertible upright. I have the attachments for it but I had never used them. Since I lost my ge canister I thought I would use the attachment for my Hoover. The suction is awful! The attachments had never been used but just in case I looked the entire hose over for a hole and there were none. I know there is no clog because the hose had never been out of the box. The vacuum does an awesome job on the rugs but when I put the hose on there is hardly any suction. And the vacuum sounds funny. When I put the hose on the motor sounds louder and kind of high pitched. Is it normal for these vacuums to have lousy suction with the hose or am I somehow doing something wrong? I don't want to do anything that might break my vacuum.
