I agree with Molly S. It's sure looking into repair, at least to compare the costs. I bought a Swivel Sweeper, via an infomercial, at least 3 yrs ago. It was a set, that was two for the price of one. I really liked it's performance from day one. I am still using the Sweeper I originally opened, and have a spare. Now, they've improved the Sweeper. It's even better. I would totally buy it, if mine were no longer working. The new design has an Elbow Joint and a touch-less dirt tray. Cool! However, just as with any vacuum or sweeper, you really must clean the bristles well to keep performing well. Having long hair, it's a must. However, I use a silicone soft broom, now, to brush most of my hair off the floors & carpet, which helps tremendously (just sharing a little tip).
