How it worked!
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.

Worked for my needs as a on/off side job contractor
LOL. Unlike the other poor fellow who’s sander was wired in reverse mine worked just fine. LED lights are a nice touch for visibility and seeing where you missed. Yes, the unit is not light but what are you expecting? It’s a big sanding/vacuum motor on a stick. The vacuum feature works pretty good. No complaints, and again, yes, when you go over a corner and the head is not completely engaged to the wall you will throw dust into the air. Just try it with a regular sander. You think dust is bad with a sander that misses some. Nothing like walking out of a tight area looking like a ghost. Overall, my only complaint is the power switch. I kept hitting it with my grip on the handle and turning it off. Not a huge issue but it seemed like it needs to be set in further to the handle. Cleans easy, can be used easily, overall I finished a newly rocked bedroom in no time flat. This will save me time and a ton of mess.

Great tool! Now its much more easier for me to finish a job. Im happy I ordered it. Good quality!

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