Hi Robin,
I have a steempro powermax! I must admit i've had this machine for six years and it's never let me down at all!! Its been a fantastic machine for me!! BUT(theres always a but
) I'm in the process of looking for a new machine and first place i went was prochem and the machine i bought 6yrs ago is the machine i could by from them again!! What i'm trying to say is i feel prochem have not moved on (machine wise)!! I think there are better machines out there in todays market! I've been to have a look at the airflex turbo this morning at cleansmart very impressed indeed!
I don't want to take anything away from the powermax as i said it's served me well and i think it's a good machine to start with!
When i bought the powermax i never researched or had a demo on any other one!
My advice would be to try a few machines before you part with your money!
Hope my advice helps a bit!
What ever machine you get good luck for the future
Billy
