Our Shark Rotator worked great. except when the wand is broken! Without them, the vacuum cleaner was useless. It was a relief to know we can only order a portion. I had some concerns as to whether it would fit our 'NV 505' model, but I was hoping the '500 series' description included that model. Although the item was described as used, it came in sealed packaging and looked like new. The vacuum cleaner sucks up dirt, dust and fluff and everything is fine.
