I need to clean my hallway carpet and have been lent a bissell spinfoamer 1337 carpet cleaner but it doesn't have instructions. I can't find any online, I think you need to put the shampoo in with the hot water(?) and shampoo the carpet, leave it to dry (how long would that take?) then hoover up with a normal hoover? Anyone have any idea if that is right? The person who lent it to me doesn't really seem to know how to use it either. Otherwise I'm going to have to go and hire one....
