dai,
where did u get your wagtail combo squeegee from or did u make it yourself?
does anyone know where to get a wagtail whirlwind in the uk.
I know wcw sell wagtails but not seen whirlwind on their site 
thanks lee.
No I didn't make it. It was the original concept they had. It had some inherent design faults and they stopped making it.
The original idea was that you could turn the blade out of the way if you needed to scrub harder, the plastic tabs on the picture were to hold it in place when you were using it as a single pass tool. these plastic tabs were prone to break. In reality, you never needed to turn it at all, all you do to scrub harder is tilt the handle down towards the glass so that the blade doesn't touch. I pop riveted the two sections together and did away with that facility.
I think that Wagtail shot themselves in the foot when they abandoned the combi, the original concept just needed a few tweaks.
The secret is in the design of the aluminium channel, it is brilliant, it is IMO simply the best single pass tool ever invented, and absolutely fantastic for inside work because it does the job with just a tiny bit of water.
The technique of using them is to go across the top of the pane twice with the pad running from one side to the other.
This puts enough water at the top to give you a start. You then snake down the glass in the usual way, the pad puts more water on, and the blade about a centimeter behind takes it off again.
This is a bit like terry Burrows two handed method, but of course you only need one hand to do it
