Just received the Shark model #ep602 after being on back-order for two months. Easy to assemble, easy to follow instructions. And then I turned it on. With most upright vacs I associate how loud it is with how powerful it is. This vacuum wasn't very loud. I have hardwood and tile floors with a couple of area rugs, it was OK on the floors but when I got to the rugs it was like trying to push a car in park with four flat tires. Not Good. I have a dog and the vac this was supposed to replace I only have to go over the rugs once, but with this vac I went over a couple of times and it still didn't get all the hair up. I am for sure sending it back as soon as I can access their web site or get ahold of somebody on the phone.
