Low pressure systems doesn’t “suck” a Hurricane north or tug it in any particular direction. They simply feed it’s existing monstrosity.

Not according to what I've read. That upper lever low from Canada is said to be the biggest player in influencing Irma's turn to the north.

The timing of it's arrival is the pivotal factor in the turn to the north.

Should be... Upper LEVEL low.

They say it will eat away at the western portion of the Atlantic high pressure system which is currently steering Irma to the west. Only then can Irma turn north. So timing is everything.
