Sooner or later, I am going to need something to clean the carpets and seats of our cars. I was thinking about getting a Bissel Little Green or something similar. But then I read a thread about “real� steam cleaners (Saeco Piccolo was mentioned as one that worked well and was inexpensive). Which works better, or are they just different tools for different types of problems. If so, what to use when? Also, just wondering – if you use the steam cleaner, where does the dirt go? Would using the steam cleaner followed by the little green with just water be a good approach?
