Customer Reviews for VEVOR Concrete Floor Grinder 10"/25.4 cm Walk-Behind Polisher 3.0HP Adjustable Machine

We needed to remove the top surface of the concrete slab to apply Radon Seal deep penetrating concrete sealer into a 2500 square-foot slab. It was far cheaper to buy this grinder ($900) and use our own wet vac, then to rent a larger commercial grinder ($2000/week) for our project. The grinder did a good job when used with water and a wet vac. No power problems at all, and it came with two sets of diamond stones (only needed 1 set for our 2500 sqft slab). It works ok using dry only with the vacuum for small patches only, but the water really helps keep the stones clean during the grinding operation. To be sure, grinding concrete and cleaning up the water and concrete slurry created during grinding, takes a lot of effort, it is a two person job, to manage the hose, 12ga electric cable and wet vac around the grinding area. But the grinder was easily managed, and has appropriate weight. The crating was well done for the Shipping to our site. Would buy one again if I ever need to grind concrete again.

Great product

I purchase this grinder to prepare my garage floor for an epoxy finish, this tools work a.saintly and effectively without any effort. It is stable and extremely powerful . It is the best tool I could of buy for my project I highly recommemded. I would of like Vevor to sell the extra disc for this machine, but they do not offer this service you must order other disc in other company.

Outstanding performance. It works very well and price is very affordable. We used continously 8 hours a day per 2 weeks

La prise à un peu chauffé et les patins sont fait pour sol très souple. Mais le service après vente a su répondre présent et m'a proposé une solution. Finalement je ne suis pas mécontent d'acheter chez vevor

Deocamdata, am testat doar functionalitatea, abia astept sa-l pun la treaba, la o sapa anhidrida.

Llego muy bien la máquina, la probé y va bien. Solo que tardo más de dos semanas y al comprarla me decía que la tendré en menos de una semana

Works great, so much better than a hand grinder. Have used it to grind about 1000² ft so far.

Great machine it ok not bad price ok not to bad fair had one issue with blade but issue was fix and good

Im a contractor, I install flooring for a living. Ive been installing floors and trim for 10 years. Im 28. It came to me with some runout. Fatness wise/in and out movement. And it was hopping around and kinda hard to control accurately. I think it was from being dropped during shipping, the shipping strap was broken and it had a big paint chip and dent in the handle metal. Cracked paint, but not cracked weld. Or it could just be that way since its so cheap. I didnt expect total perfection at 900 bucks. Either way I ended up shimming the mounting plate with aluminum cans. I had to do two bolts out of four to make it run true. Tried just shimming one bolt up, but couldn't get enough adjustment. But shimming two of the four bolts made it true within a 64th of an inch or probably less. You can barely feel any in and out movement now. Visually it looks to be perfect, but I can still feel a tiny wobble. But its running extremely smoothly now. Also the cheap attachments aren't flat, so they need to break in for 50 to 100 feet before they fully even out between them all. Then it gets extremely smooth to run. The blue grinding bits that they include are just the right Bond to cut into relatively hard concrete. No glazing issues. I have freeze thaw cycles here and it has no problems with hard concrete. Overall im very happy and impressed at the price point. They just need to ship with the mounting wheel detached so it cant bottom out on the motor shaft anymore during shipping. Them it'll bottom out on the dust shroud instead. Which is way preferable. I think a lot of people would get it and assume its just running that way because its cheap, when it might just need an adjustment. Saves a lot of headache. You can pretty accurately shim it with some pieces of aluminum can with a hole cut in the center to slide the bolts through. I think it took four shims on one bolt and three on the other and now it's pretty close to flat. Make sure to get the brushless one, its lower power than the bigger one, but the big one has a less efficient brushed motor. So you're going to be blowing Breakers for no extra power. And more overheating issues. I'm trying to include some photos of a 3X3 area that I ground in about 5 minutes but for some reason I can't include those here so. I ground about 3:30 seconds of an inch off of a 3X3 area in about 5 minutes and that was with a bunch of repositioning because it was such a small awkward space. So this machine should be able to do quite a bit of grinding in a small amount of time if you actually have room to maneuver it. The stoop that I ground was super rough and wavy and it is dead flat now.
