For your use, especially with a drain nearby, I would get a smaller portable unit.

The larger ones with higher HP and larger gallon capacity are great, but their large size makes them more "shop" vacs. I have one for example, that I use in the garage and around the yard, but I can't carry it into the attic to service my AC drains. Using it for any purpose inside the house is unwieldy. If you have a drain nearby and it only rains occasionally, I'd get the light duty vac I linked above, and vac up 4 gallons at a time, and then just empty it into the drain and start over.
