A method of cleaning robotic surgical instruments includes inserting a tool-end of a robotic surgical instrument into a tool-end cleaning chamber, the tool-end cleaning chamber fluidly connected to a system for pumping. A suction orifice of a control box of the robotic surgical instrument is interfaced to the system for pumping and then submerging the robotic surgical instrument and the tool-end cleaning chamber into cleaning fluid. Next, simultaneously drawing cleaning fluid into the tool-end cleaning chamber through a plurality of intake holes in a body of the tool-end cleaning chamber creating turbulence around the tool-end of the robotic surgical instrument drawing the cleaning fluid into the robotic surgical instrument through another orifice of the control box and through a shaft of the robotic surgical instrument, exiting through the suction orifice and subjecting the robotic surgical instrument to ultrasonic waves.
