Festool Rotex RO 90 DX Multi-Mode Sander
RatingSolid SanderIf you already have a Festool dust extractor, just buy this sander. It's silly to use anything else. If you're new to Festool and you need a sander, but this sander with a CT dust extraction system and you'll be glad that you did.
Combined with the Festool CT HEPA dust extraction system, sanding with the RO 90 produces zero dust. I've used other vacuum assisted sanders and the result is less dust, but you still have some dust, which is always a pain and even a small amount of dust will get everywhere!
Festool also offers an extensive line of pads. My first project with the RO 90 was staining and unfinished screen door. I started with 150 grit and worked my way up to 400. The result is a run of the mill veneered screen door that was turned into a beauty. Going all the way up to 400 grit may sound excessive, but it resulted in an incredibly smooth door that is a joy to touch.
RatingYou need this sander!I recently purchased the Festool RO 90. I am amazed at the versatility of this tool and with the Festool dust collection capabilities, I can use it anywhere and not be concerned about dust, unlike most other sanders. I bought it to refinish some kitchen cabinets to paint them and the capabilities of the RO 90 to go from removal of the current finish to a final sanding that I thought I could never achieve was amazing! I forgot to mention that the headlights of my old beater pickup truck look great after I went thru the steps up to 8000 grit and now they look brand new!
Ratingworks well for trim and windowsThis was my first Festool purchase. I got the MIDI package. I considered just getting the sander because I did not feel like I needed to work in the house. Of course now I do work in the house, but more importantly, the vacuum helps hold the sander flat on the workpiece. I bought the RO90 to rehab some double-hung windows. I had hoped to be able to grind off paint with it. Paint is tough. I found it was better to remove the paint by hand and then let the RO90 do its magic on the remnants of the paint. Keep in mind that have been going down to the bare wood. The biggest different between hand sanding and the RO90 is dust. So now the RO90 has found application in sanding still installed trim and even drywall. I have to say that I really don't use the triangle attachment much. I am also almost always in Rotex mode. I am considering getting a RO150 for my larger surfaces.
