In-Depth Review: Bosch ROS20VSC Random Orbit Sander with Carrying Bag
The most notable thing about the Bosch ROS20VSC Random Orbit Sander is that in my opinion it's the most user-friendly random orbit sander out there. Using it is almost self-explanatory. You turn it on and uniformly pass it through a given surface until the whole thing is smoothened out. I've seen beginner DIY homeowners to professionals using the ROS20VSC satisfactorily and I recommend this for your next woodworking project.
1) Black & Decker BDERO100 Random Orbit Sander, 5-Inch
The Black & Decker BDERO100 is way cheaper than the Bosch ROS20VSC, but cost isn't everything. The question that needs to be asked here is whether or not the ROS20VSC can justify costing nearly twice the BDERO100 in terms of specs and overall benefits. In some ways it does and in other ways it doesn't. The ROS20VSC is only slightly heavier than the Black & Decker by 0.3 pounds.
They share a 12,000 OPM speed, but Bosch has a wider speed range while the Black and Decker unit can only go one speed. Also, the ROS20VSC has extra features like a micro-filter system and a contractor bag.
2) PORTER-CABLE 382 5-Inch Random Orbit Sander
The PORTER-CABLE 382 is only slightly cheaper than the Bosch ROS20VSC. With that said, the 382 is a bit bigger and heavier by 0.1 pounds. They share the standard 12,000 OPM speed range, but the Bosch unit can go from 7,500 OPM to 12,000 OPM, while the PORTER-CABLE unit can only go 12,000 OPM because it's a single-speed orbit sander.
What's more, the PORTER-CABLE 382 has a slightly lower rating at the time of this writing, which further solidifies the high rating Bosch received. They have roughly the same specs, weight, and even size (since there are only a few inches of discrepancy). However, for an extra few dollars, you can get more bang from your buck with the Bosch ROS20VSC.
3) PORTER-CABLE 7346SP 6-Inch Random Orbit Sander with Polishing Pad
For a change, the PORTER-CABLE 7346SP is more expensive than the Bosch ROS20VSC. The question here now is whether or not the 7346SP is worth having nearly twice the price of the ROS20VSC. Some might argue this isn't the case because the PORTER-CABLE unit weighs almost twice as the Bosch unit, making it certainly more unwieldy to use.
What's more, it can only go as fast as 6,800 OPM, which doesn't even reach the lowest speed setting of the ROS20VSC (which is 7,500 OPM). However, on the flip side, this other PORTER-CABLE unit is perfect for fine sanding applications and covers a wider area faster thanks to its body size and its 6-inch disk diameter.
4) 3M Random Orbital Sander 20317, 5 in Non-vacuum 3/16 in Orbit, 1 Per Case
The 3M 20317 Random Orbital Sander is the most expensive random orbital sander on this list and article. How does it compare to the Bosch ROS20VSC? Is this sander worth the extra coinage needed to buy it? In fairness to 3M, it has probably the lightest sander on this list, so in terms of weight and ease of maneuverability, it's probably superior to everything else.
However, for something that weighs so little, it has a size that's more comparable to the likes of PORTER-CABLE 7346SP and DEWALT DWE6421K than the other more petite sanders on this list (particularly the Black & Decker BDERO100). Furthermore, it has the standard 12,000 OPM speed and an impressive rating. However, only 14 customers have rated it so far, so its rating could change in the future as more people try it out.
5) DEWALT DWE6421K Random Orbit Sander Kit, 5"
The DEWALT DWE6421K is only about few dollars more expensive than the Bosch ROS20VSC. With such a close price, do they have specs that are comparable to one another? Aside from having to live up with the proud DeWalt name, the DEWALT DWE6421K has some pretty standard specs like the 12,000 OPM single-speed rating and its 5-inch disk diameter size.
It also weighs 4 pounds, which means that (appropriately enough) it outweighs the Bosch ROS20VSC by 0.8 pounds the same way it out-prices the unit by a couple of dollars. In terms of size, it's the second biggest orbital sander on this list next to the wide-area PORTER-CABLE 7346SP (the DeWalt unit is the second heaviest sander as well).

The Final Cut
The Bosch ROS20VSC Random Orbit Sander is a highly recommended sander for beginners and advanced users alike because of how easy it is to use. It particularly excels in having features not found in other sanders (a micro-filter system) and meeting or exceeding the standards of specs it does share with other units.
It even facilitates fast removal of materials at its top speed of 12,000 OPM but can also do excellent buffing and polishing of surfaces for speeds as low as 7,500 OPM. The machine is also compatible with vacuum hoses with the size of 1¼ and 1½ inches. Long story short, even though many other sanders can outdo it in certain aspects, it's well-rounded enough to stand out on its own.
