Quick-release handle and interchangeable cleaning system

A quick-release handle adapted for use with a working head having a socket mount configured to receive said quick-release handle, the handle comprising:

• a hollow elongated shaft comprising an outer peripheral surface, a proximal end proximate to the socket mount, a distal end distal to the socket mount, the distal end comprising a distal end surface;
• a quick-release coupling assembly positioned on the proximal end of the shaft to releaseably couple the handle with the socket mount;
• a button actuator on the distal end of the shaft, the button actuator operably connected to the quick-release coupling assembly, wherein the button actuator is configured to move along the axis of the shaft between a neutral configuration and a depressed configuration, and wherein the button actuator is biased to the neutral configuration;
• and
• an ergonomic, freely-rotating knob positioned on the distal end of the shaft to rotate about the axis of the shaft, wherein the button actuator passes through the knob and further wherein the rotary movement of the knob and the axial movement of the button actuator are independent of each other,
• wherein the handle is positioned in an engaged configuration when the button actuator is in the neutral configuration such that the coupling assembly is releaseably coupled with the socket mount, and
• wherein the handle is positioned in a release configuration when the button actuator is in the depressed configuration such that the coupling assembly disengages from the coupled socket mount.
