MadMan - Those people spent $64G for dinner?!?!!!!! OUCH!!! That is WAY TOO MUCH to be spending out at a restaurant. Those people have much more money than they do common sense.
As for high priced/high end vacuums, I don't think that will stop anytime soon. There are always people out there that realize that little old saying "you get what you pay for!" is very true. Especially in today's world where everything seems to be cheaply made & made in China. About 70% to 80% of consumers will buy low & mid end vacuums, & be totally satisfied with their cleaning performance & they don't realize if they replace their vacuums more often, they might as well have just bought 1 really good vacuum that not only lasts MUCH longer, but cleans much better too.
Then there are the other 20% to 30% who do "get it" & don't mind spending over $700-$800, even into the thousands, to get a quality vacuum that lasts a long time & cleans well. Like Gmarquez said above, the cost can be justified when you factor in the extra features & engineering, longer lifespan & better cleaning performance. The fact that Miele has grown so much in recent years, selling high end German canisters that sell anywhere from $500 to $1500, proves that there are people who WILL pay those prices once they get fed up with buying low-end, disposable vacuums that don't clean well & constantly break.
As for Human/Edgar & his assertion that companies like Aerus & Kirby's competition are their own secondhand models, he makes a valid point. But, there will always people out there that, for whatever reason, despite the money they would save buying used & doing minor repairs/refurbishment, insist they don't want someone else's dirt & want to buy new. And I don't see the door to door method of selling high-end vacuums going away anytime soon. Certain brands that are "unique", like Rainbow, Filter Queen & Kirby, do need to be demonstrated to a customer for them to see the advantages of the product. And like Luxkid1980 said above, part of the reason they would buy is they are building a relationship with that dealer they can count on if something goes wrong with their new vacuum.
Kirbybb - Unfortunately, what that Aerus dealer told you about Miele motors being non-serviceable is correct. The earlier Miele canisters before 2004, that had the Ametek & Miele-made double stage motors, were indeed serviceable & able to be rebuilt. However, the Vortex single stage motor they have used since 2004, is indeed non-serviceable. Watch some of the YouTube videos out there showing Miele vacuums being repaired & rebuilt, they pretty much have to tear apart the entire motor just to get to the carbon brushes, & the skills some of these people have repairing that motor would be beyond the abilities of some repairmen working in vacuum shops. Plus I have never heard of the carbon brushes being available for the Vortex motors as a separate part. I wouldn't use that as a excuse to not buy a plastic Aerus or Miele though - bear in mind those Miele vacuums are designed & engineered to last 20 years use in most people's homes. Sure, the motor is disposable, but considering what you paid for the entire vacuum & it's lifespan, it's very much a viable option.
