thanks everyone for the replys, well, am real surprised at the amount that use manual switches, this is how i had assumed it would be, (1) remote control. (2 ) fast catching up autobrush. (3) control valve. (4) trigger (6) manual switch. (7) others. oddly enough iv been using the manual switch to, recently i tryed to buy a remote control for my trolley, reason why is that 2 weeks ago i laid my pole against the wall to turn the switch of. The pole fell sideways and broke of the brush head. the angle addaptor smashed to pieces, so with the help of jeff 1 who knows about electronics, tryed to get a reasonably good remote from maplins it was a nightmare. so this is how i come about the voting pole to see what other wfp use to activate the water, thanks jouk45
