The primary thing that a rotary air lock provides is the ability to get material from the cyclone "out" for disposal constantly without breaking the required 100% air seal necessary to prevent blow-by past the separator and without shutting the system down. They are pointed at high volume operations that can't stop to change/empty the bin.
The bottom line here...ANY form of dust collector has disadvantages and "pains in the posterior" that come with them. For those of us with cyclones...overfilling the bin and then stuffing the filter is one of them. But that's not the fault of the system most of the time...it's the fault of human error in not paying attention or ignoring the blinking light if there's an indicator. The RL type system has advantages and disadvantages, too. It's easy on headroom for sure. But it still needs to be cleaned out and emptied. Most of the urgency for both of these systems in that respect is when we are using the jointer and planer which produces prodigious amounts of material really fast. I can easily fill my 55 gallon drum in 15-20 minutes if I'm working wide material. (which is typical of me, too) How fast depends upon the species, too...some comes off in smaller chips and some comes off in very fluffy shavings which pile up darn fast and don't compress on their own in the bin.
If I lived in a place where I could exhaust outside without significantly affecting my HVAC, I'd do that. But I don't. Hot and sticky in the summer and cold enough in the winter to make it impractical to vent outside. For your area, winter would be the challenge, but the way things are going...summers aren't getting any cooler...and your shop is physically in your home.
