I am impressed with the new DC41 Mk2 performance, it's the best performing Dyson ever since the first Dyson DC01 made it has a five year guarantee and if you give them your old vacuum, they will knock £100 off (limited time special offer) and its the latest model which is yours with the option to choose 3 free tools! Incredible!
I am actually thinking of buying one myself, but the DC25 is a machine which performs good, but has a few issues such as brush motor problems and the filters get dirty quickly.
The new radial root cyclone on the 700w dc41 are fantastic and my friend vacuumed up some sawdust with his and none went on the filter. The large holes on the cyclones have been replaced by a mesh screen like a sieve, so no more hair on the filters!:) the cyclones really do their job btw :)
