About to paint a room and I want to do it properly. So as the previous paint job was rough as a badgers rear end I want to sand it all down about 52sqm am I better off doing it by hand or investing in a random orbital and attacking it that way?
It is going to be painted in little green intelligent primer then intelligent emulsion

Get an orbital. I tried by hand.. I gave up and bought an orbital. Much quicker. Just wear a dusk mask. You'll be finding dust in the house for weeks.
Just for the dust and mess I'd never use a machine again to sand walls again as they blow all the dust up into the air. Might be best getting the room re plastered/skimmed if you cant see yourself getting a decent finish with sanding by hand.sander attached to hoover.
I bought the Mirka hand sanding blocks in various sizes and they're great connected to a Henry etc, but it's bloody hard work. They're perfect for a little patch, but not so good if you have to do a whole room.
a light random orbital sander is best.
If there's really a lot of texture in the paint, you'll probably need something aggressive like 80 grit, but then you'll need to go to 120/180 to get the 80 grit sanding marks out, so that's potentially 3 lots of doing it by hand. Would be torture!!

If you have a lot of walls and/or ceilings to sand you will find it a lot easier renting one of these... https://www.hss.com/hire/p/drywall-sander-kit
sanding discs are held on by velcro and will save you a lot of arm ache and a lot of dust mess

I'd buy a orbital 100%. It's gruelling mind numbing work sanding walls. You're going to make a lot of dust and mess regardless whether you do it by hand or use an orbital so may aswell get the job done quicker and spend twice as much time giving it a good cleaning after.
On a side note, I've been looking at alternatives to sanding/re-plastering knowing when we move I've got a whole house of wallpaper stripping to do and it's anyone's guess what state the walls will be in after.
Found this online, I've not used it before or known anyone that's used it - mixed bag of reviews online where some people say it's brilliant, to others who say it's an absolute waste of time.
Could be quite expensive if doing a large area but cheaper than a plasterer I imagine and would save hours over sanding.
It's called Knauf Proroll and it's paint on plaster.

Would be to hear any comments on anyone that's used it

240 has been going ok so far on most of it will just step it up around sockets and switches.

Ah, that's not too bad then, no need to sand again after. Ha, yeah, once you start, you have to do everything, otherwise it will be patchy and you'll see the different texture throughout.It's a bit like newt in aliens "oh oh made a clean spot!" Now I've done a little bit I have to finish

That should do the job. Just take the dust bag off and attach the end of a Henry on, taping it up if necessary.
I have two tips for you regarding the dust. Firstly get a decent dust mask. I recommend the slightly more expensive ones, as opposed to the very cheapest ones. They tend to fit better because they flex to fit your face better.
Also you can use a desk fan to blow a lot of the dust out the window. Put it on the window sill facing out or on something so its perhaps a meter away from the open window blowing out. Set it so it doesn't swivel of course. This will blow quite a lot of the dust out which will in turn prevent as much going in the house, and give your mask an easier job to do.

Looks similar to Polycell Smoothover (i.e. rubbish).It's called Knauf Proroll and it's paint on plaster.

It's not getting it on the wall that's the hard part. It's the trowelling up which you need to do with this just as you would with Multifinish.
It's also expensive. Coverage: 10m² at 1mm thickness. To get over lightly stippled artex you'll need 3 or 4mm. Multi finish is £6.00 for 25kg. That stuff is £25 for 13.50kg.
In short, if you want rid of artex get a spread in to either skim or overboard and skim. You'll get a better result and the cost will be similar.
If you've just got shoddy walls that you want to fix yourself, Easi Fill and sand.

Dust free sanding.

Total cost around £550, but you will not get any dust anywhere.

The Ceros (and Deros) are about as good as it gets. Use the Abranet pads.I'm trying to justify it as I need to do living room after this and that's about 100sqm oh and I can use it for my wood working too
Extraction is just as important though if you want completely dustless. Something M class ideally.

In terms of justifying the costs, by not paying a spread to do two rooms it's paid for itself.

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 think this tends to happen on here. Mirka sanders are discussed then the OP ends up buying one.
I have the 5650 kit. I'm not 100% sure on the difference between the kit versions. I think one of the numbers relates to the orbit of the sander. 5mm orbit is the one I have. I think they do smaller and bigger, but 5mm is the "general" use one.
It was fine just with a Henry, but it'll get annoying eventually having to plug the Henry in and then plug the sander into another socket. It really does take away some of the practicality.
I bought the Mirka 1230M in the end as Dulux Decorating Centre had it on offer with 20% off. Just the sort of motivation I needed to get my wallet out.
I did an attic room that needed all the walls/ceiling sanded - no dust anywhere. Was about 8 hours of sanding!!
The Henry works OK, but you still get a bit of dust. I was reluctant to spend on a proper extractor, as I wasn't sure it'd be that much better, but it really is. And having the conveniene of plugging the sander in to the extractor is really useful.
And if you use it for woodworking as well with the nasty wood dust, the extra power of proper extractor might be more useful.
