peter, it is a pity you do not have a page on your website, exclusively about the auto brush, with pics and videos, also showing spare parts, also if it comes complete with brush, or if we can send our own brush into to have the switch fitted, ect. also some folk have a weight issue with the switch, i dont, but what if you took both metal tube connectors off and replaced with these plastic ones, that would knock i bit more weight down,
