What a waste

I bought the vaccum and two of the sfs systems as we had just moved into the house we were in and my wife was pregnant. I bought them thinking they would be great for wife and baby when he came. The vaccum has performed mediocre at best, and the filtration cost just to run it for a year costs more than a new vacuum that does the same quality of job. The air filters have worked well for us, but again the cost of the filters is obscenely expensive for what they are. I got totally burned for approximately $3600 that could've gone to much better use. Don't let the salesman in the door. They are shifty, and promise you quality, but what you're getting is an insanely overpriced dirt devil.
