DC39 -- Should I Remove the Post-Motor Filter to Clean
« on: December 07, 2021, 11:49:23 pm »
I've replaced the burned motor within a DC39--a surprisingly easy job. The inside of the post-motor filter shows some black within its pleats--likely carbon from the motor brushes--while the outside of the pleats appear clean. The job of removing the post-filter on a DC39 seems onerous and far less casual an activity than swapping the motor.

My question:
Is it even necessary and/or prudent to remove the post-motor filter for cleaning? Presumably, I can simply blast the thing in situ with compressed air to clean it sufficiently.

Thoughts? Suggestions?

It's good practice to change the filter when you change the motor. If it's clogged up your new motor wont be able to breathe and it'll burn out. Those filters usually burn anyway and are damaged after the previous motor blew.

That said, if it's not damaged and you feel the soiling is only light, compressed air would do the job.

The filter is definitely not burnt. I'll blast it with air and move on with reassembly.

Do you know the Dyson part number for the hard floor vacuum head shown in this video? I'd like to purchase it.

Looks like a 965577-01.

We might have a new one of those cheap, I'll have a look and update you tomorrow.

From the part number you provide, it appears that doodad is a "Dyson Musclehead Floor Tool".

I'll use this revived DC39 exclusively as a bare floor vac. The "Musclehead", the "Flat-Out Head" (pn: 914617-02), and the "Dual Mode Bare Floor Tool" (pn: 904136-25) appear more affective for that purpose than the somewhat anemic "Articulating Hard Floor Tool" (pn: 920018-04).

But... what I really prefer is to somehow fit the superior Dyson "Fluffy" Roller Floor Tool (pn DY-96507102, e.g.) to the wand of this DC39. Maybe I could 3D print an adapter.

Here's something I do have which will fit yours: 968626-03





You might be able to find one locally (as you're in the US), but it'd be a good solution on hard floors.

You wouldn’t be able to use a Fluffy head with a DC39. The Fluffy head has an electric motor in it and requires a low voltage power source. The DC39 does not have this capability unfortunately. So you’ll be better off looking for one of the other accessories you have mentioned instead. Hope this helps!

Figures. Still, thanks for the head's up.

Turns out the "Pneumatic" isn't available here in the states. <plaintive sigh> 

Do you have an option on which of the three bare-floor heads I listed previously is the best?

If you wanted that pneumatic head, it would come out at £65 delivered to the US (about $85). Just an FYI.
