Polaris 9550 Sport Robotic – Our Proven Powerhouse In-Depth Review

The Polaris 9550 Sport is built for tough cleaning jobs in in-ground pools up to 60 feet. Its core cleaning strength comes from the innovative Vortex Vacuum Technology. This system creates a cyclonic suction effect that helps keep debris suspended within the large filter canister, allowing the cleaner to maintain powerful suction even as the canister fills. This is particularly effective for picking up heavier debris and ensuring a consistent clean throughout its cycle. Its 4-Wheel Drive (4WD) system provides exceptional traction, enabling the 9550 Sport to navigate varied pool surfaces, climb walls effectively, and scrub along the waterline. The ActivMotion Sensor® helps it "understand" its position and adapt its path, though its navigation, while effective for overall coverage, is generally considered less sophisticated than the AI or gyroscopic systems found in the latest generation of robots. It typically completes a cleaning cycle in 1.5 to 2.5 hours, depending on the selected mode.

The Polaris 9550 Sport features a large, top-access filter canister that is easy to remove and clean – often just requiring a simple shake and spray with a hose. This canister is particularly well-suited for handling larger debris volumes, making it a good choice for pools surrounded by trees. While the standard filter is effective for common dirt and debris, for pools that experience very fine silt or sand, Polaris often offers an optional ultra-fine silt canister for enhanced fine particle capture. The solid-blade scrubbing brush works to dislodge stuck-on dirt before it's vacuumed into the filter.

A standout feature of the 9550 Sport is its motion-sensing handheld remote control. This allows users to easily direct the cleaner to specific spots for targeted cleaning, which is very handy for quick touch-ups. The 7-day programmable timer, built into the control unit, enables users to set a customized weekly cleaning schedule. One of its most praised user conveniences is the Easy Lift System. With the touch of a button, the robot will drive to a desired location (like steps or a wall), wait to be picked up, and then automatically evacuate water, making it significantly lighter and easier to remove from the pool. A durable, powder-coated caddy is also included for easy transport and storage.

The Polaris 9550 Sport is designed for relatively straightforward operation. Once the schedule is programmed, it can run autonomously. The motion-sensing remote adds a layer of manual control if needed. Filter cleaning is simple thanks to the top-access canister. The included caddy makes moving and storing the ~20 lb (dry weight) unit easier. While generally robust, like all pool cleaners, periodic checks of brushes and tracks for wear are recommended.
