From this side here are my all time worst in no particular order
Steam Way 9100
Boxxer 427
Powerclean Victory
Revenger 210
Amtex
Best based on history and and my personal opinion and in order. My dislike of clutch drives as a whole when all the pros and cons are added up does reflect in this list
Prochem 405 -do I need to say anything about why?
Prochem Peak-Change the oil and follow the service manual and it will just flat our run and run and run hands down the least worked on machine we have ever seen.
Prochem
Everest 650 Takes a beating day in day out and asks for more
OG Blueline Thermal Wave with Nissan
Powerclean Freedom 47 Every single one WE ever sold is still running today and zero major issues
So far the SS
570 has proven to be rock solid but still a "new" machine when compared to the history of others(10+ years)
Butlers-Only down side is proprietary parts oh and engines and tranny's
Hydramaster 4.7/4.8 (when installed correctly)
I do not list the
aerotech or
vortex because I could put them both in both lists. The cost to run either of them based on ROI has never ever made any sense to me. The numbers flat out do not add up when compared to ANY of the other machines on list.
Oh and this list doesn't take into consideration the GOOD machines out their like the
370SS or the Legend and Blazer or the pro 1200 or Steam way 4100 or Powermatic/Legacy etc which are great machines in their own rights
