The invention relates to an electrical suction type water saving closestool. The sanitary appliance closestool applied at present has the problems of wasting water and leaking water of a water tank for a long time, and the water resource is wasted in an astonishing way; though the traditional sanitary appliance closestool is continuously improved, the aim of obviously saving water is not achieved on the effect of water conservation; the importance of saving water increases every day, so the significance of promoting the water saving sanitary appliance is self-evident. The electrical suction type water saving closestool comprises an electrical absorption structure installed in a shell of the closestool, and a closestool mat and a closestool cover are movably arranged on the shell of the closestool; a flush water structure is connected with the electrical absorption structure, the lower end of which is connected with a defecation structure. The water saving closestool can flush water by electromotion or preserve the flush water structure of the existing traditional closestool; under the electroless condition, the traditional water flushing way can be used without influence; the water consumption quantity is set within the range of 0.5-1L, so as to be comparatively saved compared with the international standard of 6L.
