I got Peter's pole and autobrush this week. There's no swivel on the brush, but the pole swivels freely and there's no way of locking it which can be quite awkward.
The autobrush is good, but takes a little getting used to. A week in and I still occasionally turn the water off by accident! You just tap the brush off the left side of the window reveal to start the water, and off the right window reveal to stop it.
The flow control is great, but the brush itself is nothing special,.. and I'm thinking of changing the fan jets for pencil jets, and maybe fitting the whole flow control setup to a better brush eventually.
The pole is amazing though, despite the annoying swivel. It's just really easy and fast to use. I'm using it for ground, 1st and 2nd floor windows, and it only takes seconds to raise and lower. My hourly earnings have nearly doubled,... and that's on first cleans too!
