Should I get a robotic pool cleaner or a pressure-side one?

Robotic pool cleaners are the better bet. They cost more upfront ($600–1,200) but save time, energy, and chemicals by being self-contained with finer filtration (down to 2 microns). Pressure-side cleaners ($200–400) need a booster pump and add wear and electricity costs. For most homeowners, the robot pays for itself in fewer headaches.
