I was there on Thursday and really enjoyed it, went down with John Kelly and one of the guys who works for us.
New gear wise the most impressive thing for us was an adaptor for window cleaning poles to cut off the water when you're not washing the window, ie if you're walking to the back of the house. £55 each, bought 3 of them, one for each van to try out.
I also had a look at the Cimex Encapsulation system, nice but quite bulky and expensive and also the CFR 500 which looked like a nice bit of kit though if you need to change a vac motor it looked like a major task! They had a good offer on them and people were buying them.
Grippatank had a very good gutter cleaning system, or at least their poles were excellent, super light and rigid, the rest of it was pretty standard stuff.
Other than the pole adaptors the only other thing I bought was a new 5ltr sprayer.
Came away with a lot of leaflets and plenty to ponder over.
