Drain Cover mods for stuck cleaners

[JohnT]

I just got a Poolvergneugen cleaner, and it seems to like getting hung on my drain cover. It happens when the cleaner hits it a little off-center so the left wheel is hung in the air and it can't reverse or turn to get off.

Anybody have a suggestion for one of the guards or shields to prevent this?
