My experiance with heat as on the tm is not new.
Why?
Cause I use heat on the Scorpion via a Mytee in line heater which has twin chambers, switched separately so I can have full heat or half heat.
I use the Scorpion when I am doing suites because I can control the heat better then on the Prowler.
I dont like high heat on suites so pour couple bucketfulls of hottish tap water in the tank and I usually run at half heat via the Mytee.
So with 3 vacs and the CFR handtools and heat I want, I can do a good job.
So to me, a machine with 3 vacs, high capacity pump but no onboard heat is no problem, in fact has advantages over a 2 vac machine with onboard heat in the machine.
And lets not forget that whilst the Alltec 3 vac looks very nice, it does have a reduced dirty water tank capacity to be able to fit everything in its body.
Now what is better - a nice shiny machine (no practical value) or a large tanks (less bucketting).
I know which I would pick, cause I got one and sticking to it.
Of course both the Alltec and the Scorpion can be fitted with auto dump (and auto fill) but how much as an extra??
