The Polaris Vac-Sweep 280 is a pressure-side pool cleaner designed specifically for inground pools of all shapes and surfaces, including vinyl, fiberglass, gunite, pebble, and tile.

In terms of ease of use, it does not require assembly and comes ready with necessary parts, but professional installation is recommended, which might be inconvenient or add to initial setup costs.
