As I've been dealing with a leaky pool since closing, I've had lots of time to perfect my cover draining skills (always look on the bright side, right?)

I've been using my pool vacuum hose as the siphon hose, getting it started with suction from a small wet/dry vac. Works like a charm. You just have to keep the vac hose under water of course not to lose suction. Once you get it set, the water is gone lickety split.
