I think this is a good product that unfortunately has, for me, a lack of quickly accessible troubleshooting documentation. However after start up (getting it to begin), it does a good job. I was ready to return the product - still somewhat unsure. Frustrating when red light comes up and says to fill the tank and press clean when I have done just that several times and then for some unknown reason it starts up. By that time I'm ready to simply return it, alas it's a little beyond the return date. Time taken to search the internet for solutions further exacerbate the frustration.
