Robot does most of the brushing and can also do very fine filtering to achieve extremely clear water. Requires a place to plug it in, but that can be fairly far from the pool (add power cord length plus robot cord length, less a couple of feet, with consideration for where the caddy/robot will sit when not in use). The use of a robot separates cleaning from water circulation/chlorination. That is, you can clean the pool whenever you want, regardless of the pump schedule. Remote steering is available. Most people report that the robot does not clean the pool in a perfect pattern like what you see in marketing videos, but it doesn't really matter.
The suction cleaners I mentioned don't brush the pool at all; they just suck up dust/dirt and leaves. I can't personally recommend other types, but there are suction cleaners that rub the surface as well. A suction cleaner can only achieve the same level of water clarity as your filter. Many people here suggest that more electrical power is consumed by a suction cleaner than by a robot, but that hasn't been my experience. Debris goes to the strainer baskets and filter, so no extra activities are required for cleaning, although cleaning baskets and filter will be more frequent. Suction cleaners look tidier when left in the pool (no tangled cord). If you choose a suction cleaner and plan to use it through a dedicated vacuum port, a leaf canister on the hose is recommended. If connected to the skimmer, the skimmer basket does the job of protecting your suction side plumbing against blockages.
Pressure cleaners cost a lot to operate and are not recommended.
All cleaner manuals suggest removing the cleaner when not in use, but most people leave them in, except when you want the pool looking it's best, and for larger groups swimming. When stored out of the pool, cleaners will look their best and usually last longer if kept in the shade.
Just my two cents based on five pools and four different cleaners. There are lots of opinions, and many different situations, limitations and optimum solutions. All the best with your decision. Cleaners do cut down on a fair bit pool work!
On the other hand, weekly brushing and sweeping dust toward the main drain, or manually vacuuming, is not the end of the world either!
