1. A cleaning system comprising:
a dissolvable cleaner head having a top surface, a bottom surface, and a height extending from the top surface to the bottom surface, wherein the dissolvable cleaner head defines an indentation extending through the dissolvable cleaner head; and
a wand configured to be removably attached to the dissolvable cleaner head, the wand extending between a first end and a second end, and the wand comprising:
an attachment arrangement adjacent the second end and configured to move between an engaged position, in which the wand is removably attached to the dissolvable cleaner head, and a disengaged position, in which the wand is released from the dissolvable cleaner head,
wherein the attachment arrangement comprises an actuation member and an outer sleeve coupled to the actuation member, and wherein the actuation member is configured to move axially between the first end and the second end of the wand, such that the axial movement of the actuation member causes the outer sleeve to radially expand thereby moving the attachment arrangement to the engaged position, and causes the outer sleeve to radially contract thereby moving the attachment arrangement to the disengaged position;
a first sealing member configured to engage with and seal against the top surface of the dissolvable cleaner head when the attachment arrangement is in the engaged position to impede liquid flow toward the attachment arrangement; and
a second sealing member configured to engage with and seal against an inner surface of the indentation of the dissolvable cleaner head when the attachment arrangement is in the engaged position to impede liquid flow toward the attachment arrangement.
