VEVOR Electric Concrete Floor Grinder 25.4CM Walk-Behind Grinder 3.0HP Concrete Floor Polisher 86-117CM Adjustable Grinding Machine, 1730RPM 1Phase Surfacing Grinder for Granite/Marble/Concrete/Stones

The unit turn on and grind for about two seconds at full power. As soon as it touches the concrete it slows down significantly to the point where it will completely stop. You have to pick it up to restart the wheel about every 3 to 5 seconds the water feature doesn’t help with this I’m disappointed I was really looking forward to using this unit maybe mine is defective it did arrive with cosmetic damage, but I thought it would perform as new I’d like to try this product again if you would be willing to send me a new one it’s a shame this one isn’t working as advertised

Price of machine is very reasonable and works great. Highly recommended. Have worked with machines that are very expensive and of name brand. Unfortunately, the machines are bulky and very heavy.

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

The machine is well built and easy to dial in for making a nice smooth level concrete surface. Dust collection works well when you have sufficient air flow (my 5 gallon shop vac and vortex thing on a 5 gallon bucket setup worked well enough, when the shop vac filter was clean). My only complaint is that due to the machine's light weight, it really needs the aggressive diamond wheels that came with it to work efficiently on some surfaces (I was removing a tar-based waterproofing membrane from ancient concrete). Unfortunately, Vevor doesn't offer exact replacements and finding 7/8" arbor grinding wheels is not as easy at it might sound. I was finally able to find an aggressive enough wheel from Blue Rock, but it was too tall for the dust collector to touch the floor (problem solved with tape) and the arbor clearance on their 7/8" arbor made for quite an interference fit. If finding aggressive grinding wheels for this machine was easier (hint, hint Vevor), I'd give this five stars. I certainly wouldn't have been able to get through my whole house concrete floor job without it.

Very good price. The product arrived in a wooden box, and they were fast too! I used it to grind a 2 two-car garage and it worked nice. It took 2,5 hours to grind 500sf.

Bought this machine a few days ago and used it 3 days in a row grinding a bunch of hard concrete basements with a 30# grit diamond discs soft bond, very aggressive to the concrete putting the machine on the limit. I have seen some people mention that the machine gets weak and kinda stops and found that happens because the diamond discs that comes with the machine are very aggressive and sometimes can also be your extension cord, use a 12gauge one. Otherwise the machine is awesome and if you wanna run it very smooth use a higher grit# diamonds like 60# 80# with 3 arrows shapes.

Puedes usarla sinco sin parar sin que se caliente el motor

Tengo más de un año con el y estoy muy contento con el rendimiento 100 x 100 to lo recomiendo
