Besides being super absorbing, simple to handle and easy to wash, these replacement heads can be used with just about any standard mop handle you have around. Shortly after this shipment arrived, my air conditioner started leaking in a. bathroom. In my mid-80s and living alone, being able to keep after the mess with several mops prevented damage and certainly saved my sanity as I waited for the problem to be solved. I was able to soak up gallons of water before things got out of hand, then just throw the mop heads in the washer. Nothing else to clean up, wring out or dispose of. I may give some of these as stocking stuffers!
