General Pump 24" Surface Cleaner

I have a General Pump 24" hammerhead surface cleaner that has been causing streaks when cleaning concrete. What could be the cause ? It has the original tips on it

The tips may be misaligned or 1 of them may be clogged.

They were all realigned and checked for clogs. I know some people change out the tips but im not sure what i would change to.

My 20” hammerhead started to streak after using it a few years. I tried everything even readjusting the swivel, couldn’t get it to stop. I replaced the skirt after I noticed that it was worn, mostly on the front. Haven’t had any streaks since.

I’ve had streaks with surface cleaners before. It could be clogged tips. the bars that spin can also get bent causing uneven cleaning.
