My pool sweep (Polaris 280) often gets 'hung' or caught by its own water supply cord.
The photo below shows what this looks like: the pool sweep's main body and the reverse valve get caught on different sides of the cord. The sweep can't move forward because it can't pull the valve around the supply cord, and of course the reverse valve isn't strong enough to pull the main body over the cord either.
I can manually fix it, but if I leave the sweep unattended and check again in a couple hours, it's often back in the same situation.
Any tips or techniques that I should try that might help with this? The pool sweep hose also tends to tangle quite a bit, which may be a related issue.
