When did you last wash (or replace the filters?). Dyson recommends washing the filters every 3 months and replacing every year. I've had a poor suction for several months now and dismantled the DCo1 twice with no success. Last night, between reviewing replacement vacuums, I stumbled across the Dyson website, it suggested washing the filters. Gave it a go, expecting nothing, and got loads of fluff and fine powder from the filters. Dried for a day, just replace them and the machine is as good as new, fluff whizzes around the cylinder and the wand sucks like it did when new. Give it a go (cheaper than buying a new vacuum).
