I would definetely buy one if I could get a guarantee that it would not streak. I have two accounts that I do every two weeks that are literally killing my lower back and joints. My
prochem 4 jet wand is useless on these jobs. I have to use the RX on the main areas and the wand on the other areas. I am cleaning it in two weeks and will take pictures. You will not believe how dirty the carpets will be in two weeks. The kitchen is so greasy you literally have to tip toe around. I am going to clean it as well this time, and hopefully the carpets will stay clean longer. I would be willing to try out the zipper on this carpet and post before and after pics. If there is no streaking, then I might buy two.
