My new rotary arrived today, put it together with onboard tank and i was puzzled.
The solution line from the tank goes into the circular casing above the driveboard, it looks like the driveboard has holes that are designed to allow the solution through.
It looks to me that this is designed to work only with a brush as the brush will allow the solution through, unlike a pad, i expected the solution tank line to sit on top of the plate and spray directly onto the carpet, the way it is it will just soak into the back of the pad and simply wont penetrate the pad and reach the carpet. have i needlessly purchased an onboard tank ? as it is i will have to use my pump up sprayer instead.
