A powerful, easy to manoeuvre vacuum cleaner, that gets into every nook and cranny. But not this one.
Three top tips for keeping your Dyson DC40 in rude health:
- Keep all filters clean (wash or replace frequently)
- Clean all rubber seals with a damp cloth to remove dust build-up
- Occasionally lubricate moving parts of jockey wheel mechanism (springs and lever) with silicone spray
Do these things and your Dyson will love you forever.
I’m a bit of a sucker for Dyson products. They are well engineered products from the school of function over form and in my opinion, objects of art.
This Dyson wasn’t very well when it was admitted to the workshop. The owner had complained that the vacuum cleaner wasn’t picking up dirt and dust properly. The beaters were not spinning either.
The beater ‘head’ is attached to the main body of the vacuum cleaner and is held in place with a sliding clip. The head can rotate and move to allow maximum control. The beater roller is driven not via a belt from the main motor, but from its own smaller motor in the head unit. So, there is an electrical connector between the main body and head unit. As the beaters were not spinning, it seemed sensible to test the electrical connection. Upon testing, it was not working.
The mechanism on this vacuum cleaner is quite complicated and relies on levers and joints working in harmony. Dismantling the wheels, filters, brackets and covers around the motor revealed the problem. The supply that feeds power to the beater head is routed around the motor and sliding lever mechanism and a broken cable was to blame for the beaters not spinning.
Access was difficult due to the design so rather than completely tearing down the body to replace the supply loom, I reattached the broken wire with some soldering and heat shrink to make a robust repair.
After carefully rerouting the cables and reassembling the body, wheels and beater head, the beaters spun once more. Result.
After a new set of filters were fitted and a light service, the machine was as good as new.
Cost of replacement machine: £000’s. Cost of repair parts: £11.69 plus my time and two teas.
