This works REALLY well for a large yard inflatable. We have it hooked up to a 9-foot Halloween cat. It is pretty strong so we unzipped about an inch of the cats belly opening so there would not be quite so much pressure. I don't think it would work very well for a normal sized inflatable but for the jumbo ones it was great. We tried to unhook it and bring it in if it was going to really storm, but it did just fine for rain showers.
