Comfortable one-handed sanding with fast material removal and a well-blended, ultra-smooth finish.
Item #
94% of 100

The Bosch ROS20VS features variable speed, plus an integral pad dampening and pad braking system designed to eliminate the most common complaint of random orbit sander users: swirl marks on the workpiece. Finish quality is further enhanced with the use of a soft microcellular backing pad. The pliable pad ensures a smooth, fine finish on flat or contoured surfaces. The sander also features a twist-off dust canister that captures most of the dust from sanding. Its hook and loop pad makes grit changes easy, and allows you to reuse previous grits—a huge cost savings in the long term. The comfortable shape and soft grips provide multiple hand positions to prevent fatigue.

  • Twist-off dust canister is durable and compact, shows dust level, and easily detaches
  • Bosch microfilter system is the optimal on-board system for filtering fine dust and can trap particles as small as a 1/2 micron in diameter
  • Hook-Tight™ hook-&-loop disc attachment includes over 35,000 long-life hooks—up to twice the standard number of hooks—to ensure firm grip of disc
  • Random orbit sanding action delivers well-blended, ultra-smooth finish with fast removal rate
  • Soft microcellular backing pad has the pliability necessary to ensure a smooth, fine finish on flat or contoured surfaces
  • Integral pad dampening system provides braking of the spinning pad to prevent swirl marks when removing sander from workpiece
  • Variable-speed dial allows you to match the speed to the workpiece and task
  • Ergonomic comfortable soft-grip top and body provides multiple grip positions to prevent hand fatigue
  • Engineered for low-vibration for smooth operation and user comfort
  • Anti-spillback canister design minimizes dust spillback into sander
  • Uses widely available industry-standard 8-hole 5" hook-and-loop discs

Woodworking Experience:
Better than my old Bosch
It’s smaller. It’s lighter. It has variable speed. It has a nice dust attachment and port. And - it does a better job than my 25+ year old one that finally bit the dust.

It is very smooth, low vibration to the hand and the finished surface is better than the old unit produced. You can single hand it easily. I have no idea why one would spend more for a ROS.

My Makita random orbit sander goes through sanding pads very rapidly. My Bosch pads were more durable.
Dave P on Apr 16, 2020
my old one died seems like a good deal
rlm on Apr 13, 2020
I'm hoping this will work better and have more control when sanding my super nice jobs before finish sanding. I have 3 other brands of the 5" electric orbitals but none of them are as comfortable to use and as controllable as the 6" air supplied orbital sanders. I'm thinking, this might just be the one

My old Porter Cable has seen better days and I needed a new sander. I selected the Bosch after reading up on reviews of the orbital sander. It seemed to be the best value for the dollar. I like that it is a variable speed model.

Good for woodworkers with small hands. As a women, sanders often feel too bulky in my hand. This one is especially comfortable and relatively light weight.

C. M. L on Apr 29, 2020
Can this sander be hooked up to a dust collector instead of the built in filter?
A shopper on Jun 9, 2015
BEST ANSWER: Yes. It works very well with a shopvac.
Can you hook a shop vac up to it?
Russell W on Apr 12, 2017
BEST ANSWER: Yes a shop vac can be connected. The sander comes with an adapter that goes in place of the dust collection canister. The adapter had an ID of 1 1/4 inches and an OD of 1 3/8 inches. My shop vac has a 2 1/2 inch hose, so I used Rockler's universal small port hose kit to connect my vac to the sander. Using the shop vac with the sander works very well.
Is this hook and loop or psa?
James B on Nov 8, 2015
BEST ANSWER: hook and loop
does this unit come with a vac hose adapter?
Professorie on Apr 10, 2019
BEST ANSWER: No, it has a self contained catcher. It works very well.
Can I buy a buffing attachment for this sander?
Cathy M on Mar 12, 2018
BEST ANSWER: not that i know of!!
Can this sander be used for wet sanding?
