thanks everyone for the comments, glad you enjoyed it.
i can boast about these cleaners, but the truth is it took me dozens of visits to thrift stores to find them. it takes me about ten or more visits to a thrift store to find a gem like the yellow Eureka or the Kirby. its not easy. in addition, the Kirby as you see it here is not the way i found it. it had some weird later-style bag on it and it took a couple hours worth of hand polishing to make it look this good.
the commercial Eureka is 6.5 amps. it has outrageous power, perhaps too much. IMO the 6.5 and 7 amp Eurekas have too much suction. i got it (on eBay) for looks!
thanks for all the Kirby help, guys. this machine has really grown on me. i was surprised by the good airflow of this machine, and how quiet it runs. i will lay off trying to service the bearings for now, since they have quieted down since i first used it. the last thing i wanna do is break the fan and im not sure i want a plastic fan in it.
