A colon cleanse machine works by pumping warm water into the colon through a disposable tube. The water hydrates the stool and helps remove it from the colon, leaving it clean and free of waste.

A colonic machine, also known as a colon hydrotherapy machine or a colonic irrigation machine, is a medical device used for colon hydrotherapy, a type of therapy that involves flushing the colon with water to remove built-up waste.
