we have both machines and quite frankly the steempro is just used as backup. a 400psi ninja with internal steemate is far better. also been using the new ashbys powders , they dissolve much better, smell much better and my solution tank heater element is now scale free due to the inbuilt de scaler, also the recommended dilution is 1 15ml scoop per 20 litres, we have cut this down to 1 scoop per 40 litres and seems to work just as well on standard cleans.
