I'm perfectly happy not using a hop spider with my GF.
Most of the hops stick to the filter so I take that out and give it a quick blast of water get rid of them. Then I put a litre or two of cold water into the GF to mix with the remaining trub and tip that away.
I don't get blockages as such but sometimes a reduced flow rate out of the pump when I've used loads of hops in the recipe, presumably because the whole filter is covered in a very thick layer of hop bits. The filter is the current version.
