I rarely rave about customer service from any company, but I feel the need to with Dyson.
Our geriatric DC04 (about seven years old) has been over-heating, cutting out and generally dying on me lately. I called the helpline to see if there was anything that could be done or if they could recommend a new model and they suggested a service for £55. Now, I'll admit, I wanted to put the poor thing in the bin and buy a new one but DH convinced me and today old faithful was serviced. Basically, I have a new vacuum in an old case. The chappy arrived and replaced the motor, the clutch, the brushes and brush mechanism, the filter, the hose and the power cable - all for £55 (including one year warranty on work) and all within 40 minutes!
Am very impressed by the level of service offered for a very reasonable cost.
