Hey all- my first post, so please be gentle. 
First time pool owner, got a Dolphin Nautilus CC Plus a couple months ago. Think it’s been doing a pretty good job (I have no experience with others)- I know it cleans debris off the bottom very well.
That said, when there’s an algae bloom (like now) it doesn’t appear to really scrub the floor/walls so much as I hoped. I can see it leaves wheel tracks, but the machine-length scrubbers don’t seem to really be making good contact. (See image). Are they not reaching the floor?
FWIW: vinyl lined, 46’ L pool.
