I have been a Bissell customer for 20+ years with a background in technology. This is not a well designed product. The Dirty tank is poorly designed and placed and leaks when handled. It does not clean better than the Green Machine despite saying it is 40% better. I really wanted this to be a great machine. I only used it once and will never use it again. So this became an expensive door stop. I read all the instructions and I do think the idea is a great idea but poorly executed. If Dyson ever gets into this market, Bissell beware, a well engineered product is all it will take to hurt your business. I am so sorry to write this because I do love Bissell products and how you love saving animals but you guys really have to pay attention to your quality control.
