Cleaning brush is a tool for cleaning a toilet bowl, which belongs to a kind of household brush tufting machine. Generally the toilet brush is used with toilet cleaner or bleach. The cleaning brush can be used to clean the upper area of the toilet, around the bowl. However, it cannot be used to clean very far into the toilet's U-bend and should not be used to clean the toilet seat. In many cultures it is considered impolite to clean away biological debris without the use of chemical toilet cleaning products, as this can leave residue on the bristles. http://www.jaronmachine.com/brush-tufting-machine/industrial-brush-tufting-machine/
