My wife wants a carpet shampoo machine for the house. I want one for our cars carpet upholstery. Anyone have recommendations of really good/quality machines that work well for both? Looking for recommendations based on your personal experience but also those that have high reviews as well from reputable sources. I am seeing a lot of great reviews on the Bissel Little Green, but I see a newer version called the ProHeat, but doesn’t seem to be much reviewed or highly reviewed. Much appreciated! Thanks. Edit: we don’t have pets and we’re mostly pretty clean people, just looking for a machine for light/medium cleaning & that is portable.
