Eh, I'll cut them a little more slack because it seems like it does its job without a bladed fan, and the bladed fan is hidden inside. This is just straight lying, and it's immediately obvious lying too. Especially to anyone who knows anything about fanless designs - there are no external fins on the machine and it uses an Intel chip, so you probably don't even have to look at the back to know it can't be fanless.
Back in my professional housecleaning days, Dyson vacuums also seemed a lot more prone to breaking than a lot of other vacuums, mostly in a lot of simple ways as far as buttons sticking, beater bars no longer working; my favorite vacuums to work with were Sharks, though there are a lot of other very nice affordable, bagless, powerful, durable vacuums from other companies too.
I worked for a while as a vacuum repair tech years ago. It was kinda neat.
Dysons had a few specific problems. One, their cord was undersized for the power it was carrying, and would get warm to the touch, much more so than other brands. I never saw any repairs related to that, but it was indicative of a cheaply-built philosophy that had lots of other problems. Two, their rolling brushes had a simple plastic-on-plastic bearing surface (other vacuums had a plastic-on-metal or bearing-on-plastic), and as the brush accumulated hair and other things, the two plastics would melt into each-other from the friction and it would require a top shell replacement. This was a really common repair on these. Another problem, common to all bagless vacs, was a buildup of dust and grit inside the motor, causing early motor failure.
A well-cared-for Dyson is a decent vacuum, but you're generally better off getting a good Eureka for half the price and abusing the crap out of it. Those things could take a beating.
One a side note. This guy's channel is one of my youtube favorites. Some of the classic computers he tears apart and talks about are absolutely fascinating.
