One of the most modern features now being implemented by the top toilet manufacturers is self-cleaning. There is considerable debate over whether or not this feature does an excellent job in keeping a toilet clean. In my opinion, it does. One of the main reasons for a self-cleaning toilet not to work is on the fault of the user.
A lot of people don’t realize that the cartridge containing the cleaning detergent needs to be changed every few months. This cartridge is responsible for releasing the cleaning agent, but when it runs out, then it cannot do a proper job. Changing it out is simple; it is easily accessible at the top of the tank. Another pointer is that the cleaning feature does not work automatically. You need to push a button to activate it.
