This seems to be a generic problem with cleaning robots. Not finding videos of them doing hard cleaning jobs. Not even the commercial ones have such videos. Compare, say, the Barber Surf Rake videos.[1] Seaweed, rocks, storm debris, spring break - it goes down the beach and leaves clean sand behind. If these cleaning robots start showing up in restaurant kitchens, they really work. They're used in stores and airports, but it's not clear if they get the hard messes.
There are commercial floor cleaners which work by brute force. They have powerful brushes working at high pressure, and can scrub off just about anything from hard floors. But they're using way too much power most of the time, and they're big and heavy. Something with enough smarts to know when to apply brute force is a win.
The thing has a cyclone, not a bag. Cyclones are useful devices which violate the rule "you can only make something clean by making something else dirty". They're centrifugal separators - solids get centrifuged out of air. Most serious wood shops have a cyclone. Dyson vacuums have used cyclones for years, so this isn't novel.
I would also say that cyclones don't violate the rule. They end up adding the dirt to a container of some sort and I would not consider that container clean.
