Is this necessary? Answer: While rinsing after deep cleaning is optional, BISSELL recommends this step for two reasons. A final water rinse of the carpet will help remove any excess soap and which could attract dirt when your capet is dry. Running plain hot tap water will also help "flush" the internal tubing of the machine to help prevent odors which can be caused when cleaning formula/dirt is left behind in the machine.
