The present invention relates to an automatic cleaning apparatus. The cleaning apparatus includes a washing unit, a buffer unit, and a dehydrating unit. The washing unit includes a washing room, the buffer unit has a buffer room, and the dehydrating unit has a dehydrating room. The washing unit and the dehydrating unit respectively connect with the buffer unit at two opposite surfaces of the buffer unit, and the washing room is communicated with the dehydrating room via the buffer room. The buffer room includes a separating member. The separating member is accommodated in the buffer room, configured for movabley separating the washing room from the dehydrating room.本發明涉及一種自動洗滌裝置,其包括洗滌部、緩衝部及脫水部。該洗滌部具有洗滌腔。該緩衝部具有緩衝腔。該脫水部具有脫水腔。該洗滌部及脫水部分別連接於該緩衝部之相對兩表面,且該洗滌腔藉由該緩衝腔與該脫水腔相連通。該緩衝部包括阻隔體,該阻隔體設於該緩衝腔內,用於可移動地隔斷該洗滌腔與脫水腔之間之連通。100‧‧‧自動洗滌裝置110‧‧‧洗滌部120‧‧‧緩衝部130‧‧‧脫水部113‧‧‧進液管114‧‧‧出液管1201‧‧‧第一連接面1202‧‧‧第二連接面1303‧‧‧排液管1304‧‧‧導氣管
