M600 not really doing anything

So I went swimming today and decided to run the M600 while in the pool. I was right up to it looking at it scrub an spot for a good 20secs and when it moved all the sand was still there. I swipped at the sand and it moved so I know it wasnt caked on.

Any ideas as to why this thing is acting like this? I mean it does it jet thing at the water line.

The most likely problem is that the top (suction) impeller is clogged with string or ????

Other than that, I can't think of anything that you can easily repair.
