I used this to knock down a textured ceiling that had flat white paint over it. When hooked up to a shop vac (adapters come with it) , it minimized the mess SUBSTANTIALLY. Much, much faster than sanding by hand.Pros:-LED light makes things much easier to see.-DIY friendly (I am by no means a "pro")- WAY easier than sanding manually.- Made with good material, sturdy.- Price is very fair (on sale)- Comes with Extra Sandpaper and electric motor brushes .Cons:-Feels HEAVY after hours of use and can be a but cumbersome in tight quarters when hooked to the shop vac hose/electric cord)-Difficulty with edges/corners because of the gap between the sandpaper and the actual diameter of the head unit.-No locking position to keep the head unit vertically oriented, causing it to want to tilt to 90 degrees and down away from the ceiling overhead. (Non-factor for walls)

Update- my ceiling sanding is done, using this sander and a stand device I built to hold it for overhead work. The old ceilings had pull-textured plaster, which leaves blades of plaster hanging down 1/2 inch or more, and of course, had been painted. Looked like the bat-cave.The objective was to sand it down to the point of looking like a knock-down texture, which would have elevation differences of about 1/8".The lift stand was built with an office chair rolling base, a piece of conduit, and some PVC pipe, lifted with a pneumatic cylinder so as to have an adjustable weight effect for the operator. We set it at about zero when in contact with the ceiling so that a little lift up or down by hand would engage or disengage work.A similar and simpler approach could be done with springs instead of pneumatics.Both tool and lift worked very well. One man sanded a thousand square feet of ceiling- in three hours. I had expected this to take more like 10-12 hours, be very tiring and very dirty work.We didn't rely on the built-in vacuum alone, we attached a strong shop vac, and to my surprise, the work went very cleanly, so the internal dust collection worked well. No tool problems, did not wear paper down fast, worked right up to wall edges- left only small arcs in inside corners as the only place hand work was required.Overall, this was an excellent tool investment, even if I never use it again. It is the only such tool I've ever owned, and even though I've been a professional homebuilder, this is something new. I can't say how this brand compares to others; I can say- zero complaints. Marvelous tool.My earlier review-This machine is pretty well described. I'm renovating a house that had to have several layers of wall paper removed and we will have to skim coat the walls to restore the drywall surface. It also has a old fashioned coarse texture on the ceilings, which we want to sand down to create a more modern knock-down look.Wall sanding goes well. Definitely need to attach a separate vac system for dust control. One issue here is the the provided adapters would not work with a Dewalt Shop-vac, I fabricated one form PVC fittings.Sanding the ceiling is much different, because you are holding the full weight right over your head. Rapidly wears you down and I have an entire house to sand that way. So- I'm constructing a device to help. Using a swivel chair base, some EMT pipe and PVC tube with a balancing lift system, I should be able to roll the machine across the floor and control the contact pressure with a very low manual force. That's not in operation yet, I will try to post a review later of how well it works and how effective the sander is when used with it. This need would seem to be true of all the wall sanders, with the exception of one I found whose design is far superior to the normal type, with a price that is also far superior.Given the low cost and the way the machine works, I think I picked the best one available on Amazon for my purposes.

The short version... it does what it says, it sands the wall. It still puts some dust out but it definitely reduces the amount that would otherwise be everywhere. If you are doing more than one room or skim coating a large wall, then I would recommend. If you are just fixing a small area or sanding seams in a single room, then I'd say pass for the cost.The long version... I am in the process of covering poorly done wall textures throughout my house, one room or wall at a time. I messy and tiring project by myself so I was looking to speed things up and make my life easier. This does help but not as much as I had hoped.It is a little unwieldy when moving around and setting up but once you get going its not as bad. I first used it with the grittiest sandpaper to try and knock down the texture a bit. That actually worked pretty well so that is where I think the machine performed well. It did take some pressure and quite a few passes though. This is also where I think it leaked the most dust. Maybe because it was sitting higher on a very uneven surface so there was a slight gap around the edge for the dust to escape?Once the wall was skim coated I used this to give the whole wall a once over to try and smooth any accidental bumps or anything. It did much better there with dust control but I think lacked a bit with the smoothing. It knocked things down to mostly level and smoothed but it did not make things flat. I started with a very light grit paper but even moving it up a level on grit it didn't seem to change much. So I ended up doing the tuning of the wall by hand.After I was finished with the wall I took a long look at the machine and I feel like the brush that encircles the sanding pad might be part of my issue. This brush is there to contain the dust until it is sucked up but it also seems to have the effect of keeping the sanding pad at a certain distance away from the wall. Which I believe is both good and bad. I think it is good by helping the pad move around and from applying to much pressure and gouging the wall. But I think it also keeps the pad from always contacting the full area and only riding the tops of the high points. I think on my next wall I will be removing the brush and seeing what happens. Worst case is I have to redo the skim coat and put the brush back.I am glad I bought it. I just wish it was cheaper. Seems expensive for a minimal use power tool. Once I finish the walls, what am I going to do with it??? Thats why in the sort answer I said, if you have a lot to do then sure get it but if you're just doing a room or less then I wouldn't recommend.

Avec cette outil j’ai réussi à faire un travail parfait et de manière très rapide…je ne m’en passerai plus

WOW! I had been battling for weeks doing the sanding on my kitchen reno including ceiling. I'd manually sand for 30 mins, make a big mess, then give up for a few days. With this electric sander, I finished the entire job in 30 mins - with virtually no mess! Awesome. Highly recommend.

The sander is too heavy and doesn’t work efficiently on popcorn ceiling. I ended up going back to my scraper.

Works very well, and is also very versatile. Makes the job alot easier. A bit on the heavy side, but that's the only downside. Saves a ton of time

What a bad customer service company! After using the machine only twice , it stopped working. Sent numerous messages to vendor without any answer. And Amazon customer service won't help! really disappointed. I was planning on using this machine for a long time but it's GARBAGE
