A random orbital sander is the best choice when it comes to home improvement projects as well as outdoor mending works. It's because random orbital sander will reduce the amount of hard labor you put with bare hands. It works evenly and finely for both indoor and outdoor décor.
Maybe you could have chosen sanding blocks or sandpapers for your indoor or outdoor mending, but always remember; that using sand blocks and sandpapers will require much of your effort, which will be pretty frustrating for you. It's not that easy to get on with papers, plus it often doesn't stay on.

Now, the question arises that how does a random orbital sander work? A random orbital sander mainly works through the simultaneous spinning of the sanding disc, more like moving in a loop. This handheld power tool works through the sanding blades. The sanding edges provide the random sanding action.
Chiefly, it prevents leaving swirl marks. Also, the direction of the graining is not much of an issue when you sand with it. No matter the direction of wood grain is, the random orbital sander will give a smooth finishing for sure. That's why it is easily possible to sand two pieces of wood with different directions at the same time.
Did you know that a random orbital sander merges a belt sander and the speed of an orbital sander; in fact, an orbital sander has even more momentum to produce more beautiful finishes.
There are three types of random orbital sander; air-powered, electric-powered, and orbital floor sander. The electric-powered and air-powered sanders can be categorized as handheld sanders. The floor sander, on the other hand, is a large machine that will roll.
Most of the random orbital sanders, especially quality sanders come with vacuum attached to it. The holes on the surface of the sander swallow wood particles and debris. A detachable canister collects the sucked up particles within. As a result, you will get to work without the hassle of cleaning the machine sander from time to time. But do not make the mistake of not wearing the goggles just because of the attached vacuum. You must ensure safety, no matter what.
Commonly, random orbital sanders are 5 to 6 inches keeping peace with the disc size. When it comes to popularity, the 5 inches sanders are in favor because of its mobility. The pads in the random orbital sander are circular while the pads of orbital sanders are square. To control it, you need nothing but the palm of your hand. Give it a light touch; do not put over-pressure on it. Typically, discs are attached in two different ways in different sanders. One is in the hook and loop system, and the other is pressure-sensitive adhesives.
A random orbital sander cannot work without a power source. Power supply helps activate the motor inside the sander machine, and the engine initiates the rotation of sanding discs. Therefore, the drives with the attached pads move in constant circular motion resulting in a smoother finish. This rotation continues as the sanders sand the same path repeatedly. The whole process aims at delivering a more seamless finish without leaving any swirl marks.
