Well not died, but making a *horrible* noise from the main brush motor assembly.

For lolz I dissembled it - clearly they hold the main brush motor in a
jig and build the unit around i*everything* had to be removed to get to
it.

I can source a "genuine" replacement from AliExpress for -u8 ... but that
will take at least 10 days ... then even assuming it's perfectly
reassembled it's a 3 year old unit.

So had to fork out for a new one.

I wonder if I can eBay some of the components :)

Why not...

1) Buy new one for immediate use.
2) Buy AliExpress component.
Do a DIY repair.
Sell unit for slightly more than AliExpress purchase costs.
(This assumes you know precisely what is wrong and
how much it will cost to fix. Most appliances do not get
fixed because the parts cost is set too high.)

I would assume, in modern life, a thing like this would have
plastic gears and the noise came from a gear tooth failure.
Brushed motors, can have a brush failure. Good designs,
the brush cartridge can be removed and a new brush fitted.
But again, modern life, nobody stocks the brushes (carbon rods maybe)
for replacement. There is a braided copper electrical connection
on the end of some brush designs and when buying a brush, you
also ask the supplier for the "crimp" that goes with it. As the
connection is crimped for security. You don't solder those
on as the solder might melt and if the solder flows down the
copper wick it ruins the suspension principle achieved by
the copper wick in the first place. The copper wick is
intended to make a flexible electrical connection that can
carry considerable amperes.

While the noise might be the motor, it is more likely to be
something in the drive train which has failed. A cheap element
designed to fail, versus the way we used to design gear trains.
The gears may be exposed to the airflow, grit could get
into the gears.

They can make gears out of something that has unbelievable hardness.
I've seen gears, the teeth edges are just as sharp as the
day they left the factory. These are gears not made out of mild
steel, whatever they're made from. But things like laser printers,
the gear trains in those can be plastic, and eventually something
no longer meshes properly and the drive train fails. Why exactly
would a company use a good quality drive train, when plastic
is so "cheerful".

Well it was whizzing along nicely until something (maybe a tangle) caused
the main brush to make a horrible noise. So I am 100% certain that is (currently) the only fauly.

The unit is sealed and the gears are clealy somehow ****ed.

However even if I just forked out -u8 for the motor unit, the thing as a
whole is so fiddly that putting it back together functionally feels like
a challege too far. Especially as my close work eyes are done for
(glaucoma - especially bad in one eye).

And the how much to try and get for it - especially as from experience
trying to sell *anything* brings in the total chancers who will say "it doesn't work" etc. Which is more hassle than it's worth.

Which is why people sell perfectly good kit for 'spares or repair'.

I have a 1940s portable valve radio here in really good condition and in perfect working order as far as I know - its owner stopped using it when someone gave them a transistor radio.

But if I do list it, it will be under 'spares or repair' because I
cannot test it.

Well the dissembled unit is in a box.

I've never really been an eBay fanatic. However in my last role I had to
spec a roomful of kit the CEO wanted to put on eBay, so I've seen it done.

I bought a 'faulty' robovac for cheap. Turned out the main motor had bad bearings, so replaced for a few quid from Aliexpress. I also killed the charger along the way (oops) so had to buy another of those. I had to buy
the accessories for it from Aliexpress too, but they were cheap also. Eventually deemed to be too loud to use, I sold it for about -u200.

There are some good microscopes now for close work, either cheap USBs or standalone ones with screens.

I realised I was hitting limits when trying to prise a connector out two
wires got pulled out of the block. I was *just* able to put them back
with a phone magnifier and a holder.

I might list the whole box - with charger - for -u30. Not sure yet.

I have one of those helmet swing down magnifiers, plus a set of tweezers
which helps a lot.
Fortunately hands not shaky yet.

Hmm, depending on what model it is, bits it has with it etc I might
tentatively be interested. I've sent you a mail, but not sure if you read
that mailbox / it got stuck in a spam trap / etc. The email on this post works...
