Best vacuum with hepa filter for heavy shedding cats that doesn’t clog constantly

I’ve tried a few robot vacuums before, but the filters just fill up so fast and the suction drops. My apartment gets messy quickly with all the pet hair, and my allergies make it worse. I really need one that actually keeps up with hair and fine dust without needing constant emptying. Has anyone found a model that actually works well long-term?

Thanks in advance!
