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.
Once you do that, you will be able to buy a product that is exactly what you want.
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.
The belt sanders, however, are designed for heavy-duty work. So if you have a lot of space, you must go for the belt sanders.
Price
If you do not require a lot of features, as in, if your deck isn’t complicated, then you should better go for a simple model and not spend a lot of money on it.
