The invention discloses a trolley cleaning machine which comprises a machine body component, a turning driving mechanism a tipping bucket component, a water circulating component, a rotary spray washing component, a steam pipeline, an electric heating system, a water inlet pipeline and a water draining pipeline. The machine body component comprises an upper-portion cleaning work cavity and a lower-portion cleaning liquid storing cavity. Compared with the prior art, the trolley cleaning machine achieves full-automatic cleaning and is controlled in a one-key mode, achieves inner-outer all-dimensional rotary powerful spraying cleaning, has three types of steam heating, electric heating and combined heating and has an automatic water temperature controlling function. Circulating water cabins including the work cavity and the liquid storing cavity are completely separated from a motor cabin, and steam is prevented from permeating the motor cabin. By means of a cleaning method of hot water at first and then cleaning water, circulating water can be replaced and is prevented from gradually becoming muddy. The washing agent adding amount can be controlled in a combined mode through a clean water flow meter and an electromagnetic metering pump combined method, and the washing agent concentration is kept constant. The circulating water is filtered multiply and then flow back to the cleaning liquid storing cavity, and the impurity removing effect is obvious.
