A cartridge filter cleaning system, comprising:

• a cleaning chamber having:
• a container with a door hingedly coupled to the container, the container and the door together defining an interior of the cleaning chamber;
• a support in the interior of the cleaning chamber, the support comprising a plurality of shafts configured to support a cylindrical cartridge filter, wherein the support is configured to cause the cartridge filter to rotate about an axis of the cartridge filter;
• a plurality of nozzles positioned below a portion of the support in the interior of the cleaning chamber and configured to spray water upward toward a gap between the plurality of shafts, wherein each nozzle has a spray pattern comprising a flat fan pattern with a centerline, wherein each nozzle is oriented such that the centerline is nonparallel with the axis of the cartridge filter when the cartridge filter is positioned on the plurality of shafts, and wherein each nozzle of the plurality of nozzles is individually closeable;
• and
• an outlet adjacent to a bottom of the cleaning chamber below the plurality of nozzles in the interior of the cleaning chamber, the outlet configured to drain recovery water out of the interior of the cleaning chamber:
• a filter fluidly coupled to the outlet and configured to filter and discharge water recovered from the outlet;
• a drive system positioned outside of the cleaning chamber, the drive system having a drive motor operably coupled to the support;
• a water holding tank fluidly coupled to the plurality of nozzles;
