Electric Corded Random Orbit Polisher Bosch ROS20VSC Reviews

Simple Setup Process

The random orbital sander machine comes with the easiest setup process available. Firstly, you have to align the holes of the sanding disk to the eight holes visible on the ring of the sander pad. The pad will get attached to that sanding disk with the help of 35,000 long-life hooks that work just like Velcro. These hooks will ensure a never-failing firm grip. Removing it is also as easy as this. All You will have to do is peel the sander back from the pad. The removal process can get a bit difficult after heavy-duty work. But after a few tries, you can easily take it out and replace it. 

Construction and Design of Bosch ROS20VSC

Bosch ros20vsc random orbital sander comes in color blue, weighing about 3.5lbs with impressive finishing work. Many people might laugh at 2.5amps that powers this lightweight sander, but it has won the customer’s hearts through this. The sander comes with a standard 80-grain sander that works fine on everything. But some projects require different-sized sanders, which are also available for this brand. 

Unique Dust Collection System 

It has an impressive dust collection portion attached to it. The microfiber filter takes in all the dust during the work. Even at high speed, it works without any fail. To clean it, you will have to remove it, empty it and then attach it again. Bosch claims that this filter can capture even the finest dust around. However, it does impressive work at dust collecting while keeping the workplace clean and tidy. You will not even need any protectors while working with these. The sander is compatible with vacuum hoses and also has a dust-sealed switch. 

Comfortable Hold

The Bosch ros20vsc comes with no specific handle. Instead, it comes with a soft grip top and body that allows the user to change the holding position according to his comfort. This comfortable hold takes away all the fatigue and sweat that occurs in other sanders. The sander moves in a circular motion creating less vibration to reduce discomfort. 

No Swirl Marks

The common complaint that most of the random orbit sanders have is about the swirl marks. The makers designed Bosch ros20vsc in such a way that it eliminates the swirl marks. It comes with a built-in pad dampening system that prevents swirls on the surface after sanding. Moreover, it gives a smooth finish to any surface. 

Variable Speed

The speed of the sander depends on the type of work you are doing. Some require the same high speed, and some need low speed to give it a good finish. Bosch ros20vsc gives you the option to choose the speed you need from as low as 7500 OPM to the highest 12000 OPM. If the surface is too rough, low speed will not help. However, if the surface is soft, high speed can damage the surface. Most sanders do not have this option, but Bosch offers it just for you.

This random orbit sander shows high performance in a decent price range. As it is lightweight, you can work with it on the ceiling or in high places. The no swirl performance gives a professional look to the surface. Minimal vibrations with the lowest sound range make it a must-have item in a wood workshop.
