Upgrade your KOHLER Corbelle toilet with the addition of the ContinuousClean XT system, which harnesses the cleaning power of white toilet cleaning tablets with every flush to keep your bowl clean longer. Also featuring Revolution 360 flushing technology, Corbelle ContinuousClean raises two-piece elongated toilet cleanliness to a new level. ContinuousClean dispenses a consistent amount of toilet bowl cleaner with every flush to keep your bowl cleaner between flushes. Simply place a cleaning tablet in the tank compartment, set the desired amount with the adjustment dial, and the system does all the work, evenly mixing fresh water with the cleaning agent and dispensing cleaning solution into each flush via the rim jet.
