Abstract: An autoclavable bucketless cleaning system. The system includes an autoclavable vessel with an inside for storing fluid under pressure and with a first connection point and a second connection point disposed at an outside of the vessel, an autoclavable outlet regulator assembly for dispensing fluid from the vessel and removably connected to the vessel at the first connection point so as to be in fluid communication with the inside of the vessel, and an autoclavable inlet regulator assembly for pressurizing the vessel and removably connected to the vessel at the second connection point to be in fluid communication with the inside of the vessel.
