Whether you have an in-ground pool or an above-ground setup, we’ll help you decide which one fits your routine. If you’re new to robotic cleaners, you might also want to check out our guide on using robotic pool cleaners in above-ground pools.
Pros
- Extended runtime up to 270 minutes in Eco Mode
- Comprehensive 4-zone cleaning including waterline and shallow areas
- Ultra-fine 3-micron filtration for crystal-clear water
- Smart navigation with 11 sensors for efficient coverage

The Aiper Scuba S1 is a 2026 upgrade to Aiper's popular robotic pool cleaner line. Designed for pool owners who want hands-free maintenance, it tackles floors, walls, waterline, and shallow areas. With a 270-minute runtime in Eco Mode, it suits both daily upkeep and deep cleaning sessions.
The Scuba S1 uses 11 high-precision sensors and dual-path algorithms for smart navigation. Its WavePath cleaning pattern minimizes overlap while adapting to your pool's layout in real time. The dual filtration system combines a 3-micron ultra-fine filter with a 180-micron standard filter to capture everything from fine dust to leaves.
Caterpillar Treads provide strong climbing ability and mobility, allowing the cleaner to transition smoothly from floor to walls. The unit weighs 17 pounds and measures 15.3 x 8.7 x 17.5 inches, making it sturdy but manageable. App support adds convenience with Eco Mode, scheduled cleaning, and a weekly custom plan.
The cleaner requires app connectivity to access Eco Mode and advanced scheduling, which may not appeal to users who prefer simple controls. Shallow area cleaning is limited to areas above 12 inches, so very shallow shelves may be missed. At 17 pounds, lifting it out of the pool for filter cleaning takes some effort.
Overall, the Aiper Scuba S1 offers comprehensive coverage, long runtime, and excellent filtration in one package. It is a strong choice for pool owners who want a reliable, app-enabled cleaner with minimal overlap and maximum convenience. The 2-year warranty adds peace of mind for long-term use.

The Aiper Scuba S1 (Renewed) is a robotic pool cleaner designed for above-ground and in-ground pools up to 50 feet. This 2026 upgrade version emphasizes extended runtime and smarter navigation, making it an ideal choice for pool owners who want a hands-off cleaning solution. It targets those who value efficiency, app control, and a budget-friendly option through the renewed program.
Standout features include a 270-minute runtime in Eco Mode, which allows for daily maintenance without constant recharging. The intelligent WavePath navigation uses 11 high-precision sensors and dual-path algorithms to map your pool, ensuring systematic coverage with minimal overlap. In real-world use, this translates to cleaner pools with fewer missed spots, especially in complex shapes.
Build quality is solid with a durable black casing and Caterpillar treads that provide excellent traction on various surfaces. The cleaner handles floors, walls, waterline, and shallow areas above 12 inches, making it versatile. The ultra-fine filter captures particles as small as 2 microns, leaving the water pristine. The app is intuitive and allows scheduling, mode selection, and OTA updates for ongoing improvements.
Drawbacks are minor: the initial setup requires Wi-Fi and app pairing, which may be a slight inconvenience. As a renewed product, there might be superficial cosmetic blemishes, but performance is typically on par with new units. Also, the lack of a physical remote might be a downside for those who prefer not to use a smartphone.
Overall, the Aiper Scuba S1 (Renewed) offers exceptional value with its long runtime, intelligent cleaning, and robust build.

Pros
- Lightweight and portable at 18 pounds
- Excellent waterline scrubbing coverage up to 2 inches above the surface
- Smart sensors and app controls enable automated scheduling and monitoring
- Dual filtration system with a 3-micron ultra-fine layer for microscopic debris
- Long 240-minute ECO runtime and a 2-year warranty for peace of mind
Cons
- Real-time app control is unavailable while the robot is submerged during active cleaning
- App-only operation means you need your smartphone nearby for adjustments, with no physical remote included
- Premium price point may be a consideration for budget-focused pool owners
The Aiper Scuba S3 is a robotic pool cleaner designed specifically for inground pools. It combines smart navigation, waterline scrubbing, and dual ultra-fine filtration in a compact 18-pound package. This cleaner is best suited for pool owners who want automated daily maintenance without the hassle of manual vacuuming or moving a heavy unit.
The standout feature is its sideways waterline scrubbing ability, which removes scum rings and pollen up to 2 inches above the surface. Instead of moving up and down, the robot glides horizontally at a steady pace, concentrating scrubbing power where it matters. Combined with sensor-based path planning, it covers the entire pool floor systematically, reducing missed spots in freeform pools.
The Scuba S3 is lightweight and easy to lift, yet its dual brushes and strong suction handle leaves, sand, and fine debris in one pass. The dual filter system offers both a 180-micron mesh and a 3-micron ultra-fine layer for visibly clearer water. App connectivity provides scheduling, battery status, and cleaning history, though live control is disabled while submerged.
The main limitation is that you cannot steer the robot in real time during a cleaning cycle; you rely on its autonomous navigation. The premium price may be a factor for budget-focused buyers, and the included features are app-centric, with no physical remote. That said, the auto-parking function and app alerts eliminate the need to search for the robot after it finishes.
For pool owners looking for a lightweight, powerful, and smart cleaning solution, the Aiper Scuba S3 is an excellent investment. Its waterline scrubbing, long 240-minute ECO runtime, and 2-year warranty deliver strong value. If you need effortless pool maintenance and can live without live steering, this robotic cleaner is a reliable choice.

Buying Guide: What to Look for in a Robotic Pool Cleaner
Runtime and Cleaning Modes
Longer runtime means fewer recharges and more thorough cleaning. The Scuba S1 offers up to 270 minutes in Eco Mode, while the Scuba S3 delivers up to 240 minutes in Eco Mode. Both provide standard modes (Auto, Floor, Wall) for deeper cleans. If you have a large pool, prioritize models with extended runtime. The Scuba S1 also supports a scheduled mode for weekly plans, making it a hands-free option. For more on cleaning schedules, see our advice on filter maintenance.
Navigation and Sensors
Smart navigation prevents missed spots and wasted battery. The Scuba S1 uses 11 high-precision sensors with dual-path algorithms, while the Scuba S3 relies on intelligent path planning tailored to your pool’s shape. Both ensure systematic coverage, but the S3’s waterline scrubbing is unique: it moves sideways at a steady pace, scrubbing a full 2 inches above the water to remove scum rings. If you deal with constant sunscreen film, the S3’s approach is a game changer.
Filtration System
Clean water depends on fine filtration. Both the Scuba S1 and S3 feature dual-layer systems: a 180-micron standard filter for leaves and a replaceable 3-micron ultra-fine filter for dust and sand. The S3 offers two filter options, letting you switch based on debris type. For pools with heavy fine particles, the ultra-fine layer is essential. Learn more about choosing the right micron in our complete filter guide.
Pool Coverage and Climbing Ability
Effective cleaners must handle floors, walls, waterlines, and shallow areas. The Scuba S1 uses a Caterpillar Treads system to climb walls and reach above 12 inches of water. The Scuba S3 is lighter (18 lbs) and specifically designed for waterline scrubbing, moving sideways instead of up and down. For in-ground pools with complex shapes, the S3’s smart path planning ensures no corner is missed. Both models are reliable, but the S3 excels at waterline duty.
Final Thoughts
After evaluating both models, we recommend the (2026 Upgrade) Aiper Scuba S1 Robotic Pool for pool owners who want maximum runtime, scheduled cleaning, and a proven dual-filtration system at a solid value. If your main concern is stubborn waterline grime and you prefer a lighter, app-controlled cleaner with dedicated scrubbing, the Aiper Scuba S3 Robotic Pool Cleaner for Inground is the smarter pick. Both are backed by strong warranties and responsive support, so you can enjoy a cleaner pool with less effort.
