I install a lot of prefinished engineered hardwood floors in new homes. I have been using an electric planer on subfloor joints.This works fine but is dusty and time consuming. I was wondering what recommendations anyone has on a standup buffer/sander with a vac attachment to use on the subfloor pre install. Thanks.

Any recommendations would be greatly appreciated.

The electric hand planer works best for small areas. It throws chips instead of dust so it works a lot faster. The edger with 16 grit is what I use so nails don't wreck the blade if I'm not careful. You can sand into a nail and the sandpaper still works, just not as good. A bigger disc like a buffer would need to have a special head to be able to grind floor bumps better than an edger.
