Expensive vacuums are usually more quiet and, what is more important, are way better at filtering the output air, whereas cheaper ones - sure, they work, but they let a ton of dust out.
For people with allergies this is a big selling point.

Panasonic used to also make great vacuums. Basically any canister vacuum will be well-equipped. Dyson is vacuums what Beats are to headphones.
To be fair, the Dyson outperforms it very minimally in suction (I'd say like 5% better) but that doesn't justify the near double price. Also the Roborock has a 'lock' button and a much better wall mount in my opinion. It's battery is Lithium-Polymer and cleaning the vacuum is easier.
Marketing is the only reason why anyone would buy a Dyson v11 over a Roborock H6.
