Scuba S3 Cleaning Mode Guide — Which Mode to Use and When
The Scuba S3 offers multiple cleaning modes for different pool shapes and debris conditions. Each mode optimizes the cleaning path differently — here is what each one does.
The Scuba S3 has three main cleaning modes: Floor (cleans the pool bottom only), Wall (cleans walls and waterline only), and Auto (cleans floor + walls in a combined cycle). Choose Floor for heavy debris on the bottom, Wall for algae or scum on vertical surfaces, and Auto for regular all-over maintenance. If a mode does not seem to work, check that the filter basket is not full, the brushes are not worn, and the pool surface matches what that mode is designed for.
Floor Mode
Best for: Heavy Debris on the Pool Bottom
Floor mode focuses the cleaning path on the pool floor. The robot moves in a systematic grid pattern across the bottom, picking up leaves, dirt, sand, and settled debris. Use this mode after a storm, when trees have dropped leaves into the pool, or when you notice visible debris on the bottom. Floor mode typically completes faster than Auto because it skips the walls.
Wall Mode
Best for: Algae, Scum, and Dirt on Vertical Surfaces
Wall mode directs the robot to climb walls and scrub the waterline. The S3 uses its ToF sensors to detect the wall and adjusts its brush speed for vertical cleaning. Use this mode when you see a visible scum line at the waterline, green algae forming on walls, or when the pool sides feel slimy to the touch. Wall mode works best when the pool surface is smooth (tile, fiberglass, or vinyl liner).
Auto Mode
Best for: Regular All-Over Maintenance
Auto mode runs a combined floor + wall cycle. The robot cleans the floor first, then transitions to the walls and waterline. This is the recommended mode for routine weekly cleaning. The full cycle takes longer than individual modes but covers the entire pool. Use Auto mode for ongoing maintenance when there is no specific problem to target.
When a Cleaning Mode Does Not Seem to Work
Troubleshooting Tips
If a mode is selected but the robot does not clean as expected, check these common causes: (1) Filter basket is full — empty and rinse it before each cycle. (2) Brushes are worn — inspect the scrubbing brushes for wear; replace if bristles are flattened. (3) Wrong mode for the surface — Floor mode will not clean walls, and Wall mode may struggle on very rough surfaces. (4) Battery is low — the S3 reduces cleaning intensity when the battery drops below 20%. Charge fully before starting. (5) Debris is too large — the S3 is designed for fine-to-medium debris; large sticks or heavy rocks should be removed manually. If none of these resolve the issue, contact Aiper after-sales support.
How This Guide Works
The Scuba S3 offers different cleaning modes because no single path works for every pool. Understanding what each mode does helps you pick the right one for your situation — saving time and battery life while getting better results.
