with over 60 vacuums vacs. in service,some are simple vacs and more combos vacs, we use jd adams combos and now new generation fragmatics combos with the led 9 display and
credit card setup, major complaint for jd adams is switch assemblies on fragrance and shampoo hose, cheap plastic connectors that connects hose to metal housing, they come lose and when tightened they break, customer then pulls hose and every thing comes apart inside machine, Control board replacement is about 4 hrs, very tight to work inside machine to replace and if you install a connector in the wrong board connector, new board can be damaged, tech support is marginal , there are connectors to can activate to help test functions, adams is reluctant to give out this information so when their is a problem is hard to trouble shoot. because repairs are done in the field and not on an assembly line, we have had them on the phone and walk us thru the testing procedures on to find out the new replacement board is bad.
new generation fragmatics machines are working good, some very minor post shipping adjustments and very good technical support has made it easy to support these machines, time will tell how good they are but so far so good
we have no knowledge of coleman vacs,
