Hi tom,
I have a RollTek RT3, though mine is on a small trolley because Ben made mine up before he started selling them publicly. (I drove down to see him on a pre arranged day)
It is fantastic for domestic and commercial use. Light weight, quiet, runs off low revs easily.
The trolley is corroding a bit, but that’s because it’s had hypo mix all over it at times.
It’s a bit kore expensive now than what I paid, but well worth it. The roller pump means you can put anything through it, any mix regardless of strength.
It isn’t always the best for rinsing. I do you use it to rinse, but I prefer to use my pressure washer with a sniper nozzle for rinsing when doing larger jobs. Just because it’s so much quicker.
Have a look on bens website mate, and give him a ring if you aren’t sure on anything, he’s really helpful and honest.
