Title: Vax Air Cordless Duo - Stripdown & Refurbishment!
Post by: beko1987 on March 18, 2021, 08:15:15 pm
A fair while ago now, I had 2 vax Air Cordless Duos in quick succession. One given to me by a fellow collector


and one a job, being TOTALLY dead


Between the knowledge gained from the dead one and the nothing to loose aspect of the 2nd, we find ourselves tearing it apart as usual!

[attachimg=1]

I had this screw out at the top of the wand

[attachimg=2]

But couldn't separate the two parts, so left it be.

[attachimg=3]

Take the motor and bin off

[attachimg=4]

To give it it's full title:

[attachimg=5]

The hose comes off the chassis with 2 screws

[attachimg=6]

Then splits down further still

[attachimg=7]

At the top of the main chassis we see the adjusting handle lock

[attachimg=8]

This just pops off, with it's flat spring

[attachimg=9]

The top cover around the switch housing pops up too

[attachimg=1]

And lifts off

[attachimg=2]

All the buttons and springs can be lifted out now

[attachimg=3]

And we can see the 2 screws hidden under said switch housing

[attachimg=4]

We can undo all of those and remove the cover from the spine

[attachimg=5]

Noting how the wires run

[attachimg=6]

Then pulling them all out, switches and contact plate as well

[attachimg=7]

With a screw down the bottom

[attachimg=8]

The other half of the main spine can come off, revealing, bizarrely a tissue...

[attachimg=9]

Like a real actual tissue!

[attachimg=1]

We can now see where the spinal wires enter the machine base

[attachimg=2]

The hose holders can get out of the way

[attachimg=3]

This next bit was quite tricky due to how it clips together, but remove the long screw and washer holding the main pivot together

[attachimg=4]

Then with the screws removed eventually it comes away and separates, showing the PCB controlling it all

[attachimg=5]

I snipped the wires

[attachimg=6]

Which enables the 2 halves to be separated (you could just de-solder the wires from the board but I'm always worries about ruining cheap board traces...). The plastic has some mega heavy metallic flake in BTW

[attachimg=7]

Time to empty this part. Undo the screws holding the PCB in

[attachimg=8]

Under the PCB sits the trim part for the contacts

[attachimg=9]

Once the wire clamps are removed and the board is out of the way, 2 screws allow the LED cover to slide off

[attachimg=1]

Big old board for 2 LED's!

[attachimg=2]

2 more wires to snip

[attachimg=3]

This next bit was HARD, I think they push the centre bolt through the plastic with a machine, it was MEGA tight, you can see where I was leaning on it with a small pry bar...

[attachimg=4]

Stupid bolt fell out the other side once removed though

[attachimg=5]

Onto the bit that ALWAYS breaks now, the head! If your head is cracked and not fully destroyed, go buy some epoxy and get it stripped and repaired!

[attachimg=6]

[attachimg=7]

Baseplate off

[attachimg=8]

Brushroll out

[attachimg=9]

Brushroll endcaps come off

[attachimg=1]

Well, one does. The other, being Vax snaps off... Brushroll is a write off!

[attachimg=2]

Grumble grumble move on...

This random red bit unscrews now

[attachimg=3]

[attachimg=4]

Then this clear cover over the suction duct

[attachimg=5]

With a couple more screws the top cover comes fully off the head

[attachimg=6]

The bit that makes it stand up straight snaps off easily

[attachimg=7]

And it looks alot emptier now!

[attachimg=8]

Belt ID incase it helps anyone. Good luck finding one...

[attachimg=9]

The other end of the curly cable can be unscrewed now

[attachimg=1]

And the yolk and wire fully removed at last

[attachimg=2]

Leaving  this to lift out as one

[attachimg=3]

Ickle motor, probably still more powerful than the one running a gtech air ram

[attachimg=4]

Ah the fatal wheels! Assuming your bottom chassis is in tact, a circlip on either side removes the wheel axles

[attachimg=5]

[attachimg=6]

The nice front wheels come out too

[attachimg=7]

And that's the head done! Motor/Bin now.

[attachimg=8]

Motor first

[attachimg=9]

The previously washed and spotless filter shows the major drawback to this otherwise pretty decent machine, the cyclone is f :censored:g rubbish

[attachimg=1]

Peel the VAX off

[attachimg=2]

And find the secret screw.

[attachimg=3]

The other one is round the back

[attachimg=4]

And we can see the fiery heart of the dragon...

[attachimg=5]

Here is the power switch board

[attachimg=6]

Comes off nicely

[attachimg=7]

Could not split this handle either so together it stayed

[attachimg=8]

Time to remove the screws holding this together

[attachimg=9]

[attachimg=1]

There is alot of dead space being filled in here...

[attachimg=2]

The motor sits under various seals

[attachimg=3]

And the fancase looks encouraging

[attachimg=4]

But sadly this is as far as it goes

[attachimg=5]

Motor control board sits here

[attachimg=6]

Until it doesn't

[attachimg=7]

And we can start on the bin!

[attachimg=8]

3 screws hold these bits together

[attachimg=9]
Title: Re: Vax Air Cordless Duo - Stripdown & Refurbishment!
Post by: beko1987 on March 18, 2021, 08:50:18 pm
That lifts off to reveal the small cone

[attachimg=1]

Rubber seal here is quite critical, don't tear or loose it!

[attachimg=2]

These screws separate the shroud and cone from the top housing

[attachimg=3]

[attachimg=4]

[attachimg=5]

And also the shroud from the single cyclone cone

[attachimg=6]

The bin flap pops off the bin

[attachimg=7]

[attachimg=8]

Then the seal comes off the flap

[attachimg=9]
Title: Re: Vax Air Cordless Duo - Stripdown & Refurbishment!
Post by: beko1987 on March 18, 2021, 08:53:51 pm
Finally the bin flap latch pops off

[attachimg=1]

The often ignored instructions! It's just simpler with a bagged machine...

[attachimg=2]

And we are fully apart!

[attachimg=3]

[attachimg=4]

[attachimg=5]

Everything was then washed, polished and dried

[attachimg=6]

And we can start by refitting the bin flap latch back to the cleaner bin

[attachimg=7]

Sparkly

[attachimg=8]

Refit the flap seal

[attachimg=9]
Title: Re: Vax Air Cordless Duo - Stripdown & Refurbishment!

Then take a good hard hold of your loose flap

[attachimg=1]

And snap it back onto the bin (what else? ::) )

[attachimg=2]

One clean cyclone cone

[attachimg=3]

Plus some other cleaned parts

[attachimg=4]

Rubber gasket goes on the top

[attachimg=5]

Then the filter holder and shroud slide on either side

[attachimg=6]

With the screws in you can let go and refit the very bottom seal to the very bottom of the cone. Make sure its fitted properly or it'll let even more dust through than it's designed to...

[attachimg=7]

Then

[attachimg=8]

Refit!

[attachimg=9]

With the bin done, it's time to fit the battery contacts trim part inside the motor housing

[attachimg=1]

Then I built the motor back up

[attachimg=2]

[attachimg=3]

[attachimg=4]

Which didn't take long

The assembly can be slid into one side of the housing

[attachimg=5]

Then the other side

[attachimg=6]

Topped off by the cap

[attachimg=7]

Motor unit done!

[attachimg=8]

And waiting at the side for the rest to catch up

[attachimg=9]

Which it quickly is doing as we refit the front wheels to the floor head

[attachimg=1]

[attachimg=2]

Wheels back on

[attachimg=3]

Which makes it mobile again (so many got written off and scrapped for the want of this exact part in this state to be sold)

[attachimg=4]

Feed the wire through the yolk and pop it on, and start to drop the electrics back in

[attachimg=5]

Join the wires together. I soldered them, you can crimp them, it's not high voltage here.... I'd put the join somewhere else though in future...

[attachimg=6]

Air path cover can go back on now

[attachimg=7]

Then  the top cover can be screwed on

[attachimg=8]

[attachimg=9]

Post by: beko1987 on March 18, 2021, 09:07:58 pm
The red firewall can go in now

[attachimg=1]

Then the baseplate (whilst we wait for a new brushroll...  >:( )

[attachimg=2]

The fake motor housing connected up to the yolk much easier than being removed (with a helpful hard smack from a hammer...)

[attachimg=3]

Electronics back together

[attachimg=4]

This was so long ago I was still trying to use my Dremel Versatip! It's awful for proper soldering (I've upgraded to an electric station now) although for melting heatshrink or using outside on the car  it's pretty good.)

[attachimg=5]

[attachimg=6]

Feed the spinal cable through the hole in the housing first...

[attachimg=7]

Then do the cover up and refit the hose holders

[attachimg=8]

Run the rest of the wiring home

[attachimg=9]

Post by: beko1987 on March 18, 2021, 09:11:16 pm
Screw the cover back on

[attachimg=1]

Refit all the switches and latches

[attachimg=2]

And covers

[attachimg=3]

And locking brackets

[attachimg=4]

The wand can go in

[attachimg=5]

Reassemble the hose

[attachimg=6]

And it's done!

[attachimg=7]

Eventually the new brushroll arrived and I could film an after video

And these were the pictures that sold it!

Thank you for reading, I hope this helps someone in the future with theirs!
