How to choose the right one
-
Match pool depth needs
Check if your pool has steep walls or slopes. The RO-SAT25 features wall-climbing ability, making it suitable for inground pools with vertical surfaces. This spec ensures it cleans the entire waterline rather than just the floor. If your pool has gentle slopes, this feature provides thorough coverage. Verify that the cleaner can navigate the specific angles of your pool shape. This capability is essential for maintaining a clean environment without manual intervention. It handles the transition from floor to wall seamlessly.
-
Assess suction requirements
Consider the debris load in your pool. The SAT30 offers robust suction, which is ideal for medium to large pools with significant leaf or dirt accumulation. Strong suction power helps pull debris into the filter basket efficiently. If you have a larger surface area, this model provides reliable navigation to cover more ground. Evaluate your pool's typical debris type. Heavier debris requires stronger suction to remove effectively. This spec directly impacts cleaning speed and thoroughness for large spaces.
-
Check physical dimensions
Measure your pool's steps and narrow areas. The RO-SAT25 measures 14.9 inches wide and 17.3 inches long. The SAT30 is 15.1 inches wide and 16.7 inches long. These dimensions determine if the unit fits through standard pool ladders or steps. Ensure the width is smaller than your narrowest entry point. Length affects maneuverability in tight corners. Comparing these specs helps you avoid purchasing a unit that gets stuck. Proper fit ensures uninterrupted cleaning cycles throughout your entire pool.
-
Verify power source type
Confirm the cleaner operates without a tether. Both models listed are cordless, offering freedom of movement. This power source eliminates the risk of the cord getting caught on steps or ladders. You do not need to manage a power cable during operation. This feature simplifies setup and retrieval. Ensure your charging station is accessible near the pool area. Cordless operation provides consistent performance without power loss from long cords. It is a key spec for convenience and safety.
-
Evaluate navigation style
Look for systematic cleaning patterns. The SAT30 provides reliable navigation for consistent coverage. This spec ensures it does not miss spots or repeat areas unnecessarily. Systematic navigation is crucial for medium to large pools to guarantee full coverage. Check if the model uses sensors or pre-programmed paths. Predictable movement helps you estimate cleaning time. This feature is important for maintaining water clarity without constant supervision. It ensures every part of the pool floor and walls receives attention.
