Query: Completety Ineffective

All this device does is spread out carpet stains. It is incabable of extracting any of the cleaning solution that is sprayed onto the carpet or upholstery. You would be more effective with using a spray-on carpet cleaner and a rag. At least you could remove some of the stain with a rag.A complete waste of time and money.
