Hey Nigel I sold off the Swabby trailer a couple of yrs ago but it had a gum sucker attachment that you would put a vacuum hose to it.. I never used it.. The gum there seems to be no real good way to get it up except the old fashion way which is to use a 15-25degree tip on a light wand with hot water at about 3000 psi. If you go hot enough a 40 degree nozzle can be used and if you go really hot you can use a chemical tip(steam levels). But gum is a pain in the azz. If there is no fast method then you will be bogged down for a long time.. On the 3000psi with hot enough water the tip is over 6" from the concrete so there is not much marking cleaning difference after the surface machine was used.Some of the best compiled video of the mosmatic sc in action, dig the music too
More the lack of the sc in the video with the gum attachment!
What I would like to see more of is the 4 sc's in tandem running behind the trailer. That's a serious blower to be able to handle that!
It would be interesting to see that nozzle on the end of a wand to use with hot water popping gum.
