We bought a brand new Dyson DC25 Animal in 2011, we had it 2 years and used it all the time, even after 2 years the hose was still stiff with lots of use! :|
But we got a brand new Dyson DC41 Mk2 Animal about a month ago, the hose is sort of loosening up already :) I'm not really too sure why, perhaps they either used a similarly different material or done something with the thickness of the material used for the hoses..
The DC25 has 220AW of suction at the hose and the DC41 mk2 animal has 198 AW so maybe that's sort of why?
Not really a fan of vacuums with less than 200 Aw often
