Mike,
Thanks,apparently the p.s.i. on my T.M. can crank up to 2500 though I've never tried (it's a Kohler 20hp),but as you say it still falls short.I wonder though is there any way I could "top up" the difference,the reason I ask that is I notice tech-clean do a 5ft wide rotary tool requiring 30 ltrs per min and it makes me think to reach that they must have to combine 2 washers,and I wouldn't need much more just another 3 or 400 p.s.i. ,I could produce that blowing down a hose!!! --(I'm sounding desperate aren't I ) £60 an hour sounds too good to give up without a fight
Len,
Tech-Clean also do one with a vac port though I think the 18" works out at about £900 and 24" around the £1000 mark, is the westpak cheaper ? Thanks for your help, I really think with a bit of tweeking I might be able to use the kit I have ,and it really does sound a great add-on to any window or carpet cleaner with a ready made customer base,I just keep seeing dirty drives, and patios and thinking- I could clean that.......maybe!
Thanks again
David.
