Everything Dyson is overpriced dreck, except for the handheld. 5% more function for 200% more $.
Cheap vacuums are way better than they were. I bought a $60 upright at target for my office 5 years ago, it sucks (in the good sense) and is reliable. It does not have a ton of attachments, but it was $60.
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.
There is next to no reason to buy a Dyson v11 if you can also get a Roborock H6. I made my experiences here and prefer the vastly cheaper Roborock which has precisly the same build quality.
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.
