Query: A Little Disappointed

The machine vaccums ok but the attachments have never worked. I can't use it to clean upholstery or anything else. I only does the carpet and not an extremly great job of it either. I want something closer to industrial for pets. My carpet still is stained and stinks. I had to get a green machine to help fix the stains left behind from the proheat. :(
