For the sake of looking at every product from your own perspective, and not relying on the perspectives of random internet strangers, you ought to know the basic features that every deck sander has.

Sanding space size

Almost all decks are equivalent in size. However, they do differ in shape. Some of these decks have weird shapes and corners, so you will need detailed work.

Make sure that your sander offers versatility, and you are able to reach every spot with it.

But if your space is monotonous, then you better focus on the power and speed that it has to offer, rather than wasting energy and money looking for features that you don’t require.

Belt VS Orbital

There are two kinds of sanders, the belt ones, and the orbital ones.

The orbital sanders offer precision and control, but lack power and sanding apace. So for the decks with odd shapes and corners, they are recommended.
