I have a v6, I like it allot , Its fitted with the motor head. That said I am not sure I would be in a great hurry to replace it with a newer version anytime soon, Its suction is very powerful , powerful enough to do any duty's called apon it.
What I want to kow is when is dyson going to launch a full size battery powerd vacuum, Like Hoover has already done in the USA. Other manufacturers are following suit and it makes sense.
I would use my v6 allot more if the bin was bigger. Put a battery pack on a dc41 even a dc51 and Will be fist in line to buy
