We have owned 2 upright vacuums The first was the NV750W best machine I have ever owned! I purchased the extended 7 year warranty. We purchased another top of the line ZU782, the quality has gone done substantially. I called to get have two parts warranted on my NV750W, we complete a video call so they can physically see the machine and what has broken. All pretty standard really, but keep in mind these machines are olive green and burgundy red, very different. The parts show up and they are for the ZU782, so I call back and I am told they did not make a mistake and they will not warranty parts because they already have once. The only way I could get parts was to buy the parts and they would discount the parts. I have two cleaners and two warranties that I paid for. Shark in my opinion has completely gone down hill. I will never buy another shark product again. Two stars because once upon a time they had good products and good customer service.
