If your objective is easy and less to do, then the pressure side cleaner is fine. You'll have to have either a booster pump or a very high powered standard pump. Either of those options will be noisy and use a lot of electricity. The typical Pentair booster pump is pure garbage and requires that the standard pump be running at a specified minimum, so you run two pumps for the cleaner to operate. Also since, it just uses a water stream to "sweep," it only picks up the lighter items, as it has no brush to loosen up what's on the bottom. It also doesn't clean the walls. Of course, you can hire a pool service to come once a week to brush the pool floor and walls. Of course if easy is all that matters, I know people who do NOTHING to their pools. The pool guy comes once a week, and they're happy.
OTOH, if what you want is for the floor and walls of the pool to be clean, then a quality robot works so much better than what you're looking at, it's like cleaning your home floors with a vacuum cleaner vs a broom. I had two different pressure side cleaners provided by the pool builder. The first, a Pentair Racer, kept getting stuck on things. It was replaced with a Kreepy Krauly Platinum, which didn't get stuck but eventually would only run in the deep end of the pool. Words cannot describe what a difference the 3-brush Maytronics M500 made. The first time I ran it and saw it climb the walls and clean along the water line, I was amazed--but only until I saw how much stuff it picked up, and then I was really amazed. Yes, it is definitely more trouble, as I will not leave my $1,200 cleaner in a pool of chlorinated water. I run a 3.5 hour cycle about once a week, take it out, dump the debris it's colleted, rinse with fresh water, and store on the caddy that also holds the power supply on the covered patio.
