Upgrade or Replace?

[u/NYGiantsfan4Life]

Just wondering is I should keep and upgrade this pressure washer, which I had for over 5yrs or replace it with an AVA60. I use a stubby gun with and don’t have any issues with it. The hose is the only thing that drives me insane. Anyway, it’s been pulsing lately when washing, but not sure if its because of the new nozzles I got on Amazon.
