I do   

However, I use 38mm vac hose. I'm thinking of buying a vac with a 51mm inlet but want to keep my poles as they are probably a grand to buy now.

I'm wondering what diameter Nick Days carbon poles are?
And if they sell their machines without poles?

[DeLuce]

Yeah, I do too 
Got them off Grippa  some time ago, they've been great. I also bought the 51mm cuff for my piddling little T30  nilfisk wet/dry vac that is still going and doing a decent job after a few years. Wouldn't mind upgrading to a stronger vac soon though.

Was all the rage a few years ago until smarty pants started making guttervac poles exclusively for grippa.

Hello,

Our poles are 51mm diameter and we do sell the machines separately.
