I have seen a couple different Aerus Floor Beautifiers (now known as Floor Pros--Models B-9, B-10, and on) in which the dispensers no longer attach to the machine; they fall out unless held on by string, tie down cord, et cetera. It seems that this is caused by a broken or worn catch on the dispenser's spring-loaded handle which renders it useless to secure it to the counterpiece. Is this correct? If so, can the handle be replaced, or does one need to order a whole new dispenser? Otherwise, what is the reason a dispenser does not snap into place?
