I asked a few places about Central vacuums... airflow etc is hindered by the length of the hose. Considering central air vacuums have huge amounts of pipe/hose before it gets to you... It has been stated they are the weakest in terms of actual cleaning performance. Might be convenient and the motor is outside... but thats about it.
Black - I saw similar stuff to what you posted on youtube tests myself, not by sales people or manufacturers, but simply people with interest in vacuums that happen to own a few different vacuums and can demonstrate.
vcuumdevil - Ferrar Lamborghini I would understand, but in this case, when one can be bought for $1200 (miele electro model) or a $4000 rainbow which is 'weaker'... I fail to see the comparison. Like this you are paying ferrari prices for a regular sedan.
But the filtering system is awesome... Miele don't let anything in the air either... so I fail to see the benefit to that either. To me it feels like they are simply banking on "But it washes the air" - Dude you can't wash air. You can take dust out of it, but wash the dust? Dust is dust...
What they need to do, to justify such an exorbitant price on the rainbow is actually make it have over 120 CFM at the Nossle. Then at least if you want a Kirby or Rainbow... both cost the same and perform much of a muchness. Like this you are paying Kirby prices (Ferrari Prices) for a machine that is mediocre and no 'stronger' than machines at 500 bucks (regular sedans). So wheres the logic to that? There is none, may as well get a Kirby then for that price, at least you get what you pay for with those.
I love the concept of Rainbow... but come on... release a model with real airflow so that there is some logic to buying the machine and I would get it.
Anyway, regarding the C3 - I have low carpet. It isn't the thick fluffy stuff... and 2 cats.
People at Miele recommended I get the Cat and Dog C3, Red canister, $500, comes with turbo brush and mini turbo brush, Settings are on board the canister. 2000w motor.
I also liked the Blue one, which had the +/- on the handles (settings done via the handle, but also has buttons on board to adjust that way too if you prefer), it had rubber wheels instead of plastic, so that you don't damage wooden floors which the red one didn't, and that one has a 1200w motor instead of 2000w.
Then you got the electro models, which are $1200 (from $500-650 vs $1200 now), has everything the other ones have + electric brush which alone is $450 and usable on the model, not usable on the other models. However it also has the 2000w motor not the 1200w motor...
Do I even need the electric brush?
