those several new Kirby patents...
may be nice by the first glance but to IMHO they miss the basic "keep it simple" style. Extra motorized power brush? Why? Then you could just market a good canister. Or in other words: This would make Kirby make their Kirby vacs obsolete by definition.
Extra gears instead of a belt lifter? Why? Bison had gone that way, but got stuck (maybe they should have done some more research, can't Kirby continue down that line?) Of course, all these extra steps to lift the belt should not be there or at least automatic, this is 2011 after all. Click! Nozzle attatched and working.
Double intake port? Why? Suction diverter valves have been around for so long, all those uprights having extra hoses onboard. Sebo stuff et al.... not for me.
Bellowed exhaust to bag? (this one patent there) Why? Why could it be so important to have the bag mounted IN the handle? Sideways wasn't bad after all, was it? Just the necessity for the "emptor" was gone, as paper bags or high-efficiency fibre filters would do away with emptying out heavier stuff. (And DON'T come around your corner telling me it was for "catching stuff" like rings or legos, I am completely on the side of that one post "having a large-object trap in FRONT of the blower unit". Once rings go through the fan, they are ruined and worthless.)
And finally I must agree: The basic main Kirby must keep its classic appearance, it is a divine system of good workmanship and cleaning power, yet the caddy and the accessories leave a lot to be thought over. (Cheapish to me, compared to the high price of the main Kirby and compared what you can get for less money). A metallic wand and some well-thought-of nozzles should be minimum. Never liked any of the that stuff, neither with the older Heritage machines nor with the G series (a Kirby that I LOVE).
It's like buying a grand label business suit, finding a sewing kit inside one of its pockets....
And please please please! Do away with these horrible brass bushings on this forever rattling zip brush. After a couple of years, they all go cranking, shreaking, whining or scratching (so much for what I had found here, NONE would stay for more than five years without servicing or changing parts.) Diverter blades suction-side are good for extra speed, thank you! Curved turbine blades as well, thanks again! But this spring loaded main bushing and the top pin bushing are a nuisance. No matter whether balanced (up to G4) or whether weight-counterbalanced (beginning with G5, the G6 still having both versions around).
I hope Kirby will take their time in making it good. (GOOD! that is, sort of a WOW! machine).
