Tony,
No, I've got two, a Titan 875 and a Cub. Cub doesn't do ships tho, well not at that height.
It is very impressive, I think that to myself every time we do a job that high and that long, which is often. The really impressive part about it is the overall performance of the system which is mind blowing given what it is doing and given that we only have three hours to clean around 700 sq metres of very dirty carpet, which on the face of it can't be done but it can, if you know how
