Bosch ROS20VSK 5'' Variable-Speed Random Orbit Sander with Carrying Case

Item #
96% 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

Bosch Randum Orbit Sander
I have never had any issue with any of the Bosch tools I have purchased and my workshop is full of Bosch tools. This was a replacement for a random orbit sander I had owned for at least 15 years and the reason I purchased another Bosch is the dependability and realiability of Bosch tools.

Bosch Orbital Sander
Excellent - Haven't started the project that I bought his for but from tests and a minor sanding project - I'm in love with this sander - primarily for the dust connection to a Vac. It must get at least 90% of the duct So much better than the palm sander I was previously using
Haven't played with the variable speed so don't know
Overall first impressions are great - after all, it is a Bosch and I have not been dissatisfied with any of their tools

Bosch Sander
I have used this sander for well over a year, and have run it for hours. It has never let me down. I connect it to my ShopVac, through a couple of attachments, and it is a bit cumbersome, but works okay. The dust collector that comes with it is pretty useless, as it fills up very quickly.

review of new sander
i only used it once so far, and briefly-just to smooth a couple table tops-med speed and 400 grit disc-worked very nicely- only issue is the filter really got filled up quick and spill over came about very soon-i'l try hooking up to a shop vac next-clean up was easy and all in all the unit was a pleasure to work with

Are there different types of sanding pads available for the Bosch ros 20vs sander?
A shopper on May 15, 2015
Where to find the vacuum attachment -VA C002 ?
Wildbill on Dec 2, 2016
BEST ANSWER: Inside the case is an adapter that plugs into the sander. Into the adapter I had to purchase an additional adapter that choked the size down from my ShopVac (think 2 1/4 or 2 1/2) down to the 1" or so adapter that came with the sander. It's a bit cumbersome, but works okay, and much better than the built-in dust collection receptacle that comes with the sander.
