Hello,
I have a Karcher K6.50 and I'd like to know which EcoBooster to choose between the 180 (K7 compatible) and the 145 (K5 compatible). My heart is between them ;-)
Hello and thank you all, I've just received an official reply from Kärcher advising me to use the eco!Booster 180 with the M adapter (reference: 2.643-950.0.). So, the highest pressure nozzle, but with an adaptor that will be useful for other accessories.
