This creation is about a cat litter cleaning device and its rotation control system, including the front plate, the back plate, the rotating structure, the base structure, the switch kit and the filtering device, and the associated rotation control system. The rotating structure is combined with the front plate and the back plate to form a cylindrical case having an access opening for the cat to enter and exit. The filtering device is detachably disposed on a side wall of the rotating structure, and the filtering device has oppositely disposed box openings and a mesh bottom surface having a plurality of smaller gaps. The cat litter is placed in the rotating structure, and when the filtering device passes through the placed cat litter with the rotating structure, the cat litter agglomerate in the cat litter exceeding the size of the mesh bottom space will be left in the filtering device, wherein The creation and rotation control system can sense the litter agglomeration in the litter cleaning device and control the rotating structure to rotate and filter the litter.本創作係關於一種貓砂清理裝置及其旋轉控制系統，包括前板、背板、旋轉結構、底座結構、開關套件及過濾裝置以及所搭配的旋轉控制系統。旋轉結構與前板、背板組合成具有進出開口以供貓進出的筒狀箱體。過濾裝置可拆卸地設置於旋轉結構之側壁上，過濾裝置具有相對設置的箱體開口以及具有複數個較小空隙的網狀底面。於旋轉結構中有放置貓砂，當過濾裝置隨旋轉結構而穿過所放置之貓砂，則貓砂中超過網狀底面空隙大小之貓砂結塊將被留置於過濾裝置中，其中，本創作搭配旋轉控制系統可感測貓砂清理裝置中的貓砂結塊而控制旋轉結構旋轉過濾貓砂。
