Tumblers will clean your brass from one firing to another after reloading. It will clean the outside much more than it will the inside of the brass. As you are finding out there are lots of choices to be made in this reloading process. First like everyghingelse there are many brands, but the all do the same thing, clean brass. Some brands make two sizes, regular and extra large for large amounts of brass. Unless you are going to clean 300 or more brass at a time, say .223, you don't need an extra large unit, plus they cost more. A regular size will probably be fine. As far as brands its Chevey vs. Ford again. Everybody has their favorite brand. My first one and second one are the Frankfort model sold by Midway. Why that model, price. Look for them on sale from Midway. Seems like they are sell frequently. They are also a quality tumbler in my opinion. Why spend more than you need to?
Along with the tumbler you will need cleaning media. There are two kinds with two purposes. First there is walnut media for cleaning the brass. It's coarse and hard, to do the cleaning. Also, there is corncob media to do the polishing of the brass, which would be after cleaning step. Some guys do both steps. Personally I have only used the corncob for cleaning and polishing in one step. I recently bought a second tumbler to use the walnut media and do the polishing with the corncob in my second tumbler. Just curious to see if it really does make a difference. There is also a brass polish agent you can add to the media to help polish the brass more, which Midway also sells. Is it needed, it's up to you. It is not too costly and will last you awhile.
Two other items I got put onto by my son are a flash hole deburring tool and a primer pocket uniformer. The flash hole deburring tool removes any metal burrs left in the flash hole when the hole is made. Sinclairintl.com has both tools that I use. Flash hole deburring is a step you will only do once in the lifetime of the brass. The primer pocket uniformer is designed to cut the depth of primer pockets to the correct depth SAAMI specs. and also cleans the carbon out of the pocket after each firing. I was amazed when I used each tool for the first time how much brass came out with each step. You think the new brass is perfect, but I found out first hand it needs some improving before reloading. Lots of fellows will tell you these 2 items and steps I have just told you about are not necessary, but they do make a difference in the quality of your reloaded ammo and its performance.
The Sinclairintl.com site has both items I mentioned plus lots more to look at, most of which you don't need, but it's good resource.
You are asking the right questions. Keep them coming and keep on learning. There is lots to learn and you always keep on learning more.
