A cleaning assembly has a reservoir, a pressurized loop and a cleaning head. The reservoir contains water having oxygen and ozone. The pressurized loop provides a means for adding ozone and oxygen to water at high pressure and dropping water pressure to a comfortable level. The cleaning head is detachably connected to the reservoir by a sheath and a quick coupling and has a distribution cup having multiple protrusions. The cleaning head applies water having oxygen and ozone for cleaning excretory and reproductive organs.
