I have never used the Eco so can't really compare. I have a Sprayborg which is a great machine but I find the Phoenix is a little faster. The Phoenix has a larger orbit, may have a higher rpm and also has some up and down tamping action. I have a dozen 2.5 gallon jugs for both machines and bring all the solution I need. Makes for quick and efficient cleaning on commercial carpet.Do you think it would be an upgrade? Mytee made a lot of junk, but the Eco is a great unit that cleans great and fast.
“Tamping action” denotes, ‘scrubs a lot more’…“Tamping action”
