My Bosch sander review
When I received my ROS20VSC from the folks at Bosch, I wanted to do a really in-depth Bosch sander review to show what this random orbit can handle. As all woodworkers know, sanding is something that you have to do a lot of. As a tool that you will be spending quite a bit of time using, you should choose one that fits you ergonomically as well as having the performance to give you smooth surfaces.

My Bosch sander review: First Impressions
As this is my first Bosch sander review I was thinking as I pulled the Ros20vsc Bosch sander out of the box that the fit and finish of the sander was impressive. It weighs a substantial 3.5 lbs and has a nice heft to it. The dust collection portion of the tool is pretty impressive. I liked the way the micro-filter system attaches and works with the Bosch sander during high speed material removal. The noise level was not bad at all. Definitely better than a few of my other sanders where even with hearing protection they are still pretty loud. I don’t have a noise level meter so I wasn’t unable to get any numbers for this Bosch sander review.
My Bosch sander review: Putting it to the Test
In this Bosch sander review I was determined to push the Bosch ROS20VSC sander’s limits and use it on some end grain cutting boards that I was refinishing. I felt the cutting boards were a little chopped up as I am not gentle with it, so it was the perfect time to test out the ROS20VSC. I started at a lower grit with 40 grit sanding discs and went all the way to 320 grit, the end results are shown with the attached photos, they speak for themselves.
I found it extremely easy to move during sanding usage with the regular dust bag/box on. However with the Bosch dust extractor, the suction is pretty crazy and you have to have an air hole on the vac to ease up on the suction.
However if you just use the regular micro-filter system, it works great. The dust gets trapped in the hard box and you can empty it out at your convenience. The box is securely mounted to the back of the sander and with a quick twist the box comes off to empty or to change over to plug in to the dust extractor. I am impressed with the dust collection on this sander, it just doesn’t want to let dust escape. Everything just gets sucked right up through the 8 hole sanding discs.
Even with the endgrain it was able to perform admirably. I have to say this may be the first sander I reach for before any other ones I have for general sanding duties.
I found during the sanding of the endgrain cutting boards, that it gave me a smooth finish on the tough surface. As opposed to my other smaller sander it doesn’t leave huge swirl marks for me to take out later.
For this Bosch sander review I wanted to really make sure that I picked a tough project, which the endgrain is. I also wanted to make sure that this sander was comfortable to use for long periods of time. I am happy to report that it is very comfortable to use and hold in my hand. Even after prolonged use I didn’t feel the fatigue of holding on to the sander. Even after using it to run through the several sandpaper grits I switched to, to get the cutting board to the mineral oil stage.
I have included a photo of the refinished end grain cutting board, and you can tell how smooth the sander left it. I didn’t use any other sander during this process. I wanted to know if I only had this sander, would it perform as I needed it. You can tell for yourself what it can do.
Here is a video of the sander in use with the Bosch dust extractor without the air hose open.
My Bosch Sander Review: Final Thoughts
I am impressed with this sander, I felt it performed like a larger and more expensive sander. It just feels right in the hand, everything feels like a great deal of thought went in to the engineering of this Bosch random orbit sander. Everything worked together as it should, there is no fighting to get the dust collection system open and switched over. There is no fighting to turn it on or to change sanding discs. It is a simple yet powerful sander that will fit the needs of a woodworker that sands as part of their workflow.
