There are plenty of extractors on the market. Basically the same as vacuums but with a socket you plug the sander into. When you turn the sander on, the vacuum will start automatically and run for a few seconds after you turn the sander off.
For instance

Powerful machines, so when you are sanding make sure the filter doesn't get clogged or the motor will overheat.
Do not use a sander without a suitable vacuum extractor.

Did you miss the link to a perfectly adequate extractor that I posted earlier?It's £140. I ran the previous model with a Mirka extractor for several years.

Or the sebo but Mrs would kill me
I use a Deros with Abranet, hooked up to a normal Henry. No visible dust. If I was a pro, then would get a proper M-Class for maximum health protection, but for diy, its fine.Or the sebo but Mrs would kill me
The hose may need an adapter to fit your vac, I use this type: https://www.mirka.com/product/#/8393001511/Adapter...

I have just done this myself, used an orbital sander to get the worst of the imperfections out followed by an Aldi "special buy" dry wall sander to get the surface flat again. lots of dust so get a good mask with plenty of spare filters, windows open with outward facing fan. I also left Henry turned on and that seemed to help the dust clear.

I've never known anyone machine sand plaster walls.
If a quick blast with something like this

doesn't work then it's better to re skim

I’d be using a fairly big sanding block, with some good quality fairly rough paper on, sand in straight lines up and down. A random orbital sander will chew soft plaster to bits and leave your wall with curved marks on it. As well as be hard work, vibrating like crazy all day long.

No, for pro status you'll need a 5p carrier bag to keep your tools in.and a Skol habit

Head over to any of the pro decorator forums/Facebook groups (actually don't, it's not the most exciting of subject matter ) and you'll see them all switching to Mirka's with extraction for this very purpose.
I don't understand... very quickly you'll be through the hard outer and the surface falls apart - particularly on older plaster.If it's rough it needs filling / skimming not sanding
I'll admit the fancy extraction / sanders would be perfect for the resin worktops we've just fitted - my god that was dusty.

I'm not saying sand it until it's all flush. I'm saying fill the imperfections with Easi- fill and then sand (120 grit should be fine for plaster). You'd need to be very aggressive with grit and pressure to burn through 2 or 3mm of finish to hit the backing coat.If it's rough it needs filling / skimming not sanding

I'm multi-trade so always skim. But this is a DIY'able solution which with a bit of work can give the same results as a re-skim.

Fill and light sand - fair enough - that didn't seem the OP intention.https://www.youtube.com/watch?v=6wa_m_RKWjw&t=...

However IME the older plaster you have less than 1mm of hard outer before it all goes to crap.

Also multi-trade (diy) and nowadays I actually prefer to easil-fill the whole thing and sand down. Especially ceilings. Literally skim the whole thing with filler using a larger trowel, and then sand down. Perhaps repeat once more if needed.With a good sander, it's much less demanding physically than skimming, plus you can paint same day as opposed to waiting for it to dry.
Did a flawless ceiling last time around, took out all cracks in a lathe & plaster, bonding to the lathes then filled and sanded. Deros doesn't weigh anything and hose is long so nice and easy.

Right thinking
The 5650 cv deco kit at £380
If you haven't already, look on ebay, some good deals tend to be on there from reputable authorized sellers. Useful to get a package including sheets, as Abranet isn't sold by many (any?) retail stores so saves waiting for delivery later.The 5650 cv deco kit at £380
With you mentioning woodworking later I would say once decorating is done, sell it on within the guarantee period (3 years?) and should easily get most of it back.
Reason for this is that imo Deros isn't the best tool for woodworking-great finish sander, but takes ages for any hardwood stuff needing major work - it very lightweight so you need to apply pressure. (I did floorboards using Abranet HD and whilst came up fine, would have been much faster with a more aggressive device such as the dual rotex stuff).

I have one such vacuum myself, from Screwfix, £70. It is basically a decent sized ‘shop vac’. Very useful having the automatic on/off when using the sander. I’d recommend wearing hearing protection if you have a sander and a vacuum going at the same time for a while. ...Powerful machines, so when you are sanding make sure the filter doesn't get clogged or the motor will overheat.
