  • the method further comprises providing a cleaning pad 9108 and removably attaching the cleaning pad 9108 to the flaps 9104.
  • the method may also comprise providing a locking mechanism 9164 wherein providing the locking mechanism 9164 comprises providing catches 9170 extending from the flaps 9104, movable latches 9171, and a trigger 9173.
  • the flaps 9104 can be rotated into a closed position and locked with the locking mechanism 9164.
  • the method further comprises providing a connection assembly 9107 comprising an upper portion 9107A, a lower portion 9107B, and a joint 9106.
  • the connection assembly is pivotably connected to the frame.
  • a surface is treated with the flaps 9104 locked in a closed position with a cleaning pad 9108 attached by pivoting the treatment head 9100 about the connection assembly 9107 and rotating the upper 9107A and lower portion 9107B relative to each other by the joint 9106, as needed.
  • the method further comprises providing a release mechanism 9174 wherein providing the release mechanism 9174 comprises providing an upper actuator element 9175 at least partially disposed in the upper portion 9107A of the connector assembly 9107, and providing a lower actuator element 9176 at least partially disposed in the lower portion 9107B of the connector assembly 9107.
