I'm prepareed to bet that fully kitted it will weigh a ton!!
It only has 12 months warranty on the body, my Powrflite has 5 years.
Working at high pressure my machine gets through 50 litres in about
15-20 mins, and Wonderwand jets are small , if recovery is any good,
you'll be emptying it, every 10 mins.
There is no way the heater can run with all 3 vac's running, so any time
saved on cleaning will be eaten up waiting for the tank to warm up.
if you must have 3 vac's then a 2 vac machine with a booster is the way
to go.
I know they are well built, and look quality, but fibre glass is heavy stuff.
