Absolutely Great Tool! Excellent Investment.
This unit is sold as a drywall sander, but I used to sand our rear (covered) wood deck prior to sealing. It had been a few years since I had last worked it so there was a fair amount of weathering. I wasn't sure how well it would come out since the unit is designed to be applied against a vertical drywall and I would be using it against a horizontal wood floor. This was one of the less expensive units with an older technology motor (with graphite brushes). More expensive units have a brushless motor. I liked the fact that it had LED lights to illuminate the sanded area and especially the vacuum bag to collect the sanding dust. As it turned out, this sander worked absolutely great on my deck floor. They give you a number of sanding disks (100 & 220 grit), but for wood, I had to order 60 and 80 grit disks to expedite the effort. I was simply amazed at how well this sander did the job. It requires a little bit of patience. I did runs at 60, 80, 100 and 220 grit and the results were excellent. The motor has multiple speeds which is great. I had read comments that the vacuum did not work well, but it did for me. As the job progressed, some of the vacuum holes in the sander get clogged but that's normal; you just clean periodically. I'd say the dust vacuum performance was quite acceptable, and it collected most of the dust. Overall, I was very pleased with the purchase; the sander worked like a champ. Also nice is the duffel bag they give you for storage, plus an extra set of brushes once the ones in the unit wear out (which I suspect will take a long time). I would definitely recommend this product. I did not use for its main purpose, but I suspect it would do a great job on drywall too!

Drop the coin and get the prouduct
For a DIY this is a 10 star product. I hate Sanding Sheetrock, for that fact I dislike doing anything with sheetrock, it’s a mess, heavy to be around, but I digress, back to the review…. I always sand to much and my wife complains I have made a mess with dust (dust on everything..can you relate??) Problem solved with this tool. It’s fast, effortless, and attaching it up to a shop vac with a long hose to pull the dust made it “virtually” dustless with what I would call professional results. As I mentioned I have a long shop vac hose (ordered from Amazon) for my orange color box store shop vac which allowed me to place the shop vac outside and run the hose inside attaching directly to the sander. Sanded the kitchen remodel literally in minutes. It’s a tad heavy to hold for long periods if you are doing a ceiling, but again this is a DIY user not a person that does it for a living that would have a lightweight professional grade sander. It folds down nicely to place in its storage bag waiting for its next DIY job. I highly recommend if you order also get a long hose for your shop vac with multiple hose ends so you can clip on the proper size end onto the hose for a snug fit to the sander end. Yes it has a dust bag attached, but I didn’t use it so I can’t review how well it collected dust, personally I think the shop vac is a better option. Also order a selection of different grit sanding disks. The grit range I used was 180 to 220. The Sanding speed switch on the sander I didn’t go much higher than 2 or 3 (out of multiple speeds) and most times I used slow speed 1 to help ensue I wasn’t sanding to much or tearing the Sheetrock. It came out beautiful with professional results, I have been asked by neighbors “who did my Sheetrock work, because it looks great”. 😉. Top coat with a good primer, texture if you wish and use a high quality paint for professional results, but remember it all starts with the tape, mud and how well you sand. This tool sands well with 10 plus stars for this DIY user. Don’t go crazy with mud, remember, applying mud is an art, spread it out and float it. It a wall illusion that it’s all looks flat and consistent to the eye. Happy Sanding.

A solid machine - solid review
Yes, it's heavy. You need to sand and take breaks. It doesn't wear you out any more than hand sanding (I prefer this sander hands down). In fact, it gets the job done A LOT faster and better. The 9" disc makes smoother, more even sands (vs digging holes in your work). The finished product is great. The only negative: the write up says the dust extraction on this tool is amazing- no...far from it. It collects about 5-10% of the dust. It's so dusty, you can't see what you are sanding. The light is amazing. But, with all of the dust, it's worse than driving through the fog. I saw a review where a guy used this setup and got no dust on him (he must have only sanded 5 seconds...bc you'll look like a snowman after a few minutes). The fix: if you leave the bag off and hook it up to a shop vac (using 2 circuit breakers), the shop vac will pick up 95-98% of the dust. With a shop vac, this sander gets 5 stars. In fact, I'd recommend buying the sander without the bag. Dust extraction, with a vac, far outweighs hand sanding...worth the investment. I've only used the grid/mesh sandpaper. Regular sandpaper might be horrible on the dust (even with the vac - not sure). I'd recommended buying cheap 9" disc sandpaper and punching your own holes in it (it'll be near impossible to buy sandpaper where the holes match the sander).

Excellent tool!
I do quite a bit of building and drywall work, drywall repairs, partition wall making, etc...and was currently working on a bathroom addition in the home. Drywall, as anyone knows, is just a messy job, and I needed something to keep the dust to a minimum since this was inside the home next to a bedroom. This tool did the job perfectly. It's easy to handle, it sands great, and collects the dust from the mudding while sanding. I have to admit that I connected my hepa vac to the output port and not the bag, but even so, if you watch the video you will see the dust come off the wall but then immediately get sucked back in by the suction from the tool. Yes, the vacuum pulls too, but that suction came from the head of the tool. Awesome machine at a very affordable price. Highly recommend. And yes, if you are not accustomed to heavier tools, this may be a little more difficult but it really isn't that bad and take breaks while working. It sands so smooth and fast that you can afford to take a break! Overhead ceiling work wasn't bad either and it was nice not having the dust fall all over the place!

Blows dust everywhere, defective unit or misleading reviews?
The vacuum feature is completely non-functional. At maximum setting, airflow actually reverses and blows air FROM of the bag instead of blowing INTO it. At minimum setting, maybe 50% capture rate. Either my unit is defective or the positive reviews aren't telling the whole story. The real issue: this design mounts both the sanding motor AND vacuum motor at the head, making it significantly heavier and harder to control than tools with mid-handle motor placement and a rotating shaft. Now add the fact that the vacuum doesn't work - you're forced to run an auxiliary shop vac while dealing with an already unbalanced, head-heavy tool. The built-in vacuum motor just becomes dead weight making the job harder. It's also loud enough to require hearing protection. The frustrating part is the construction quality, fit and finish are actually impressive for a $100 tool. Everything feels solid and well-made - if only it actually worked as advertised. You're paying for integrated dust collection that either doesn't work or is assembled backwards, while carrying extra weight that serves no purpose. The glowing reviews make me question if I got a lemon or if something else is going on.

Great Tool
This drywall sander works great & is definitely a great addition to my tool's for projects. I used this to help a friend with a bedroom renovation and was amazed at how well it worked. This sander makes the job go quickly & way less messier! The built in dust collection system keeps the dust down to a minimum amount! There are LED lights that make working in low-lighted areas no problem without getting out extra work lights. The extendable handle makes it easier to reach ceilings and high walls. It is priced great and even comes with sanding pads to get you started on your first project. Quality built & had stability when in use. It has some weight to it but isn't overly heavy so it's still easy to work with. I think with a quick change of grit/sanding pads I could use this for other projects than just drywall sanding! I can't wait to start another project to use this as it made the job go quick & gave great finished results!!

I wouldn't buy it again
This sander worked fairly well and my ceilings are pretty much smooth now. I had to buy extra sanding pads, though, as I ran out pretty quick. But that could be because I had a big job. But be warned: it is extremely heavy. I sanded all of the ceilings in my house and I had to constantly take breaks because of the weight of the tool. The vacuum also did not perform super well and the suction was weak. The vacuum bag was really difficult to take on and off. The plastic clamps that held it in place were WAY too stiff so it took a lot of effort to remove and put back on. Overall, it works well, but it is heavy and some design choices are inconvenient and frustrating.

Works great! And great for the price!
I haven’t used it, but I have previously used this electric sander and I really like it how it works. The only difference that I noticed the one I borrowed for the speed switch it was a turning know and the one I bought it has bottoms.
