Electric shavers NEED cleaning…!!!!I have carefully removed the modest cut material, never thinking that EACH of the 3 cutters had become blocked… I was horrified, the tight mess of acculumated, tight matted hair…. Clean the whole cutter head, each one. I used a brass Barbacue brush… have to be seriously cleaned every 2-3 weeks.. not a 2 minute project… will serve you much better if not full of junk in cutter heads, peace, Simon
