I have bought 3 scrubbing bubble automatic shower cleaners with the two buttons to spray this past year and the cleaner works for a while and then when you push the button it beeps but the sprayer doesn't go around , i replace batteries and then i try moving the sprayer part on the bottom and sometimes it work and other times it doesn't . I bought your automatic shower cleaner 3 years ago with one bottom for our other bathroom and that one still works. I want to keep using your cleaner but please advise I cant keep spending $30.00 every 3or so months.
