I never heard about him, but I think he's full of it. Seeing as he was a auto mechanic and technician, and then a hair stylist, and then a vacuum repairman? That's worrying. "Career hopping" so to speak. Not someone who has been in vacuum repair for a lifetime and garnered a lot of knowledge. He just went through the standard sales routine about Miele and Sebo that vacuum shops give you when you apply for the job and went on with his day of telling people to throw out all their old outdated vacuums and get the best Miele and Sebo and Riccar vacuums.
When asked about Rainbow, Kirby, or Filter Queen, he just responded with a snarky "There's this new thing called "The 21st Century". You should look into it."
Again when asked about a Rainbow: "Toss that dinosaur to the recyclers. At best, the Rainbow would pull half the suction of a Miele, and be far harder and more expensive to use."
Like mostly everyone on the entire userbase of reddit, they are likely very obstinate and inexperienced on their given subject and want to prove to everyone they know things so they sit on reddit for some hours posting whatever they just learned to people looking for a simple place to get an answer by someone, regardless if it's true or not. It's the equivalent of asking the kid clocking in his 20 hour week in the hardware store on how to strip and stain a deck.
They probably got brainwashed on some on the brands of vacuums they follow and they probably believed some fancy corporate sales flyer that sold them on a plastivac. He does seem to pump those Miele canister vacs so much, I guess that is what he has been led to believe. It's like a drinking game - take a drink every time he says "Miele" in those AmA's!
The weight of a Kirby is attributed to the power drive system on the Kirby and the build quality of the motor and their thick metal construction built to endure. Those 90's self-propelled Hoover Windtunnels are just as much of a boat anchor as the Kirby is - odd nobody complains about those?
Also the fan quality of a Kirby is a null point because it is dependent on how you run the vacuum and if you abuse it or not. Any janitorial job will tell you first off the bat to inspect the floor prior to vacuuming to look for any large foreign objects or materials. Makes sense to do that at home, right? I've never needed a fan change on my 2002 Ultimate G.
Also I find it funny that in one AMA he tells you to avoid washing vacuums with soap because it attracts dirt and makes them get gunked up faster - but then in the next AMA he tells you to have your carpets professionally cleaned yearly, who use....guess what? Lots of soap. Where does it go when you vacuum? Into your vacuum. It also gums up your carpeting to boot.
I also got a good laugh at him saying Kirby "having poor suction and being overly complicated". Right, a vacuum that has no "quadruple helix gas fusion turbine powered root cyclones" and has never changed its design in 60 years has bad suction and is too complicated? Oooooookay then.
Also for someone that knows 'so much' about vacuums, his youtube account is pretty pitiful and vacant:

My recommendation: get some of the real experts here on this site to teach that guy something so he can stop sucking people into his deep space Miele wormhole.
