         12 . The system of  claim 1 , further comprising a display, wherein the processing circuit is programmed to provide guidance by displaying, on the display, an image of a section of the irrigation area that has not received at least minimum irrigation. 
     
     
         13 . The system of  claim 1 , wherein the irrigation fluid comprises an antibiotic. 
     
     
         14 . The system of  claim 1 , further comprising:
 an ultraviolet light source;   wherein the processing circuit is further configured to control the ultraviolet light source to disinfect the irrigation area.   
     
     
         15 . A system for irrigating an infected implant area, the system comprising:
 an irrigation tool;   a navigation system for tracking movement of the irrigation tool; and   a processing circuit comprising a processor and non-transitory machine readable media with instructions stored thereon, the processing circuit configured to:
 determine an area to be irrigated, the irrigation area including at least a surface of an implant and patient tissue; and 
 control the irrigation tool to automatically adjust a pressure of a spray of irrigation fluid from the irrigation tool to provide a first pressure when debridement is of the surface of the implant and a second pressure when the debridement is of the patient tissue. 
   
     
     
         16 . The system of  claim 15 , where in the processing circuit is further configured to control the irrigation tool to irrigate the irrigation area with the spray of the irrigation fluid.
