No. Water can flow only in the forward direction. You gotta open it to clean it.

No, that can never happen. Canister filters are closed systems, meaning
that there is no air inside the system, thus it works as a circulation pump.
No head. You probably are confusing this with an open system, meaning a 
system in which water flows in the open, such as in a sump system. These
_can_ backflow.
