I was in Lowes the other day looking for substitutes items for which I usually buy Porter-Cable (PC). Now that PC is owned by Black & Decker I expect they will go downhill soon. The items I usually get are Routers and Random Orbit Sanders.

I started looking at the Bosch for the ROS and noticed the ROS20VSK. It had a price of $70 so I picked it up
to check it out and it has a price reduced tag on it for $45. Well, I couldn’t pass up 31.5% off.

It doesn’t seem quite as powerful as the PC, but then again there was not as much vibration either.
The power switch is kind of mushy (can’t think of a better term).
For the seeming lack of power and the power switch, I gave it 4 stars.

Variable speed is pretty nice.
Dust collection is great. Comes with a 1/2 micron filter and an vacuum adapter. Looks like it’s for a 1 1/4 to 1 1/2 hose. The container that holds the dust is semi clear also, so you can see how full it is.
It also comes with a plastic case. I don’t really care for cases though.

All in all for the price it seems like a great deal and a nice little sander.

Here is the factory stuff.

I have a Porter Cable and a Craftsman ROS. The PC is a better sander, but the Craftsman has a better feel. I’m curious how the Bosch compare to the PC.

A bit of a sucker for tools Gary, just like me. I will walk in for some sand paper and walk out with a jack hammer. LOL

I’ve been keeping a couple of older PC ROS alive by replacing parts as need. I do like Bosch products, though.
How many holes are in the sandpaper this sander uses? I ask because I buy paper in the 50 count box and have hundreds of disc of various grits. Thanks for the post.

thanks for the review gary. I was unaware that b&d owned all of those companies. I currently own a 5” craftsman ROS. Its the only one i’ve ever used so its hard for me to compare.. good excuse to buy another one?? i doubt the LOML will agree…...

I bought this sander from lowes the other day also, mine was priced at 59.00 so you did really good. It’s funny how nothing is what it seems anymore when it comes to big cooperations they seem to all be owned by eachother! Ridiculous! I remember when you could buy 20 different kinds of soda in one little town. Not anymore! Coke or Pepsi anyone? Bahhh!

Thanks, Gary, for the heads up on the sale on this sander which BTW had a very good tool rating in a FWW article within the last year or so. It showed the most uniform scratch pattern. I have been lusting after this sander for a while and now it looks to be discontinued. Just got the floor model without case or manual for 34.95. Even a blind pig finds the occasional acorn.

Douglas – It was my understanding that this is the latest model, just released the first of the year.
It’s pictured as the latest on their website.

You got a better deal than I did!
