Dyson DC04 brush problems
Sadly, I’ve seen loads of these older Dyson machines at the tip in recent years. I suspect, with a bit of fettling and cleaning, they could be brought back to rude health.
This one was one a high-mileage example and needed some tinker-time to get it back to a serviceable condition.
It was working of sorts, but failing to ‘pick-up’ as well as it used to. It turned out that the roller had two problems. The main bearings were worn, making a squealing noise and the brushes had worn low. This part used to be available from Dyson, but due to the age of the machine, they quite reasonably, stopped selling them. However, the net is awash with reasonable pattern parts for Dyson machines and while I tend to stick to original equipment wherever possible, a replacement roller from ebay for under £10 was a reasonable choice for this 15 year old vacuum cleaner. A replacement Dyson vacuum cleaner would be at least £250 for a basic model at time of writing.
Just a note on Dyson machines: Having studied the company at school and following their progress for a number of years, they seem to be a firm believer in providing accessible and affordable parts to keep their products alive. They’re an excellent example of a company that truly believes in product sustainability.
