Classic (asthmatic) Dyson DC01

A tired DC01 gets some TLC

Starting a new job is always fun and when a new colleague of mine mentioned that the office vacuum cleaner had packed up, I rose to the challenge.

I’m quite fond of Dyson products as some of you know, mainly because:

  • They’re well-engineered, by engineers
  • They’re designed to be repaired easily with simple tools, which is better for everyone
  • Parts are readily available at reasonable prices

The DC01 was launched in the early 90’s and was Dyson’s first market clean-up, competing with the established market leaders.  Although this machine is over 20 years old and Dyson no longer supports it directly, reasonable quality pattern parts are available on eBay.  If you have one, love it and keep it going.

FixItWorkshop, Worthing, November’18, Dyson DC01

This one is actually an ‘Antarctica Solo’ model (grey and light blue instead of yellow), which commemorated Sir Ranulph Fiennes’ solo trek across Antarctica and raised money for Breakthrough Cancer.  It had been abandoned and was moments away from the skip.  I felt quite sorry for it.

Faults reported included; no suction, excess noise and smell!

The first thing to check on the DC01 is the filters, as like many other Dyson products, people forget to clean or change the filters.  Both filters were totally choked and full of all sorts of detritus.  A quick shake out and wash with warm soapy water and they were as good as new.  Following that, I inspected the seals around the join between the cylinder and the main body.  All the seals were dirty, so a clean up and quick spray with silicone spray and they were as good as new.  Great.

The noise seemed to be coming from the front beater/ rollers which usually means, noise bearings.  The beater on this model uses a two bearing set up.  One was fine, but the other was seized.  As I didn’t want to spend any more than I needed, I cleaned the bearing, after removing it and the dust cover, re-greased it with LM High-Melt Point grease (general automotive stuff) and it was ready to roll and beat again.

Once the filters were dry and re-installed, the Dyson ran like new again.  Very satisfying.

Cost of replacement:  £15 second hand, £100’s for an equivalent-ish new model.

Cost of repair:  Patience, washing up liquid, two cups of tea.

Bissell Powerlifter Pet noisy roller beaters

Now, some of you will remember that I’ve written about a similar issue before, but I think it’s worth covering again as often, complete replacement items need to be purchased, which can be costly.

This Bissell Powerlifter Pet vacuum cleaner had snapped a belt, due to an obstruction in the roller/ beater area and while the casing was open to replace the belt, I removed the beater to see how smoothly it turned.  It was noisy.

Seemingly, Bissell will only supply a complete unit for around £30, with shipping, so given the overall value of the machine, it seemed sensible to have a look at the noisy component on the bench.  The bearing housings, located at each end of the roller, come out easily and with some careful manipulation, each bearing can be removed.

On this unit, both bearings were dirty and dry.  Now, I could have replaced them with a generic bearing, but in the spirit of thrift, I decided to clean the bearing races with brake cleaner and then repack with high-melt-point grease.  When reassembled to the roller/ beater, it ran very smoothly and was much quieter, once re-fitted to the vacuum cleaner.  Job done.
