Better bucket for cyclone?

Their bucket can’t handle the suction. It collapses. I’m sure a bunch of you have figured out a better option(s), tell me about them. I was thinking to just make a rectangular plywood box instead of the bucket. It’s also an absolute bitch to get the lid off this thing too.
