This is Kohlers Cimarron One Piece Elongated toilet with a Class Five flush technology. This toilet has a great and powerful flush, but unfortunately the direct jets are not strategically placed.
When I called for Kohler for Support, Ashley told me this is how it's suppose to be like. She even said it's their second strongest flush technology. She said I should have known this before I purchased the toilet, but I only researched the toilet online and the Kohler website flush technology page mentions nothing about the Class Five not doing a complete and thorough clean flush! I love the strong and powerful flush on this toilet, unfortunately the water does not make contact with the entire toilet.
