It's funny but possibly because I grew up with American canister vacuums I vastly prefer the wire reinforced hoses used on American style vacuums to the miserable "crush proof" ( they aren't ) hoses sold with most European vacuums. Miele hoses are especially heinous, being both too stiff (to the point they flip the canister over) yet easy to kink,, leaving a wound you can never fix ( and it will kink there again, and again, and again ). Kenmore / Aerus / Filter Queen and old US made Hoover hoses that are wire reinforced never ever kink and never fight you like a Miele hose. Sebo hoses are better mainly because they are longer and I suspect adding two feet to a Miele hose would cure some of what bugs me about them. The hose on my Lindhaus Aria is longer and easier to manage, but very soft and I have to exercise a lot of care with it to avoid kinking it. On some of my Swedish Electroluxes I use a neoprene wrist brace on the hose canister end to keep them from kinking.
Kenmore made their hoses exit the canister straight up to improve airflow, and the difference in airflow between the straight swivel and earlier angled swivel is measurable on an anemometer. But the hose would often develop a weak spot from being bent all the time there and they sometimes flipped canisters over so recently Kenmore has returned to the angled swivel. The 600 Series has such high airflow I don't really miss the extra airflow the straight swivel provides. The 600 Series is just great overall design. Kenmore really thought that one out. I have Kennys going back to the late 1940s including just about every Sears Best model and all the different Progressives and an Elite canister and of all these the 600 is the best. Better materials, better fit, and better function than any of my old Kennys and much better than any of the Progressive series. And for the price it has to be one of the all time great vacuum cleaner values.
