Buy the robotic pool cleaner.

Yes, robotic cleaners are worth it over suction-side ones.

The big difference is independence. A suction-side cleaner hooks into your pool’s existing pump and filter system. That means your pump has to run longer, you’re on the hook for more electricity, and the cleaner is only as good as your pump’s suction. They also tend to get stuck more often and have a habit of climbing walls poorly.

A robotic cleaner is self-contained. It has its own motor, filter, and a smarter navigation system. It scrubs walls and floors better, catches finer debris, and filters on its own—your pump can rest. You just plug it in, drop it in the water, and let it do its thing. The catch is upfront cost (they run $600–$1,200 vs maybe $200–$400 for a suction-side), but over a few years you’ll save that in pump wear and electricity.

If you have a small above-ground pool or don’t mind a little manual brushing, a suction-side is fine. For any real pool, get the robotic. It’s less hassle, cleans better, and you’ll actually use it.

Your pool will be cleaner with less of your time wasted.
