The Aiper Scuba X1 and Scuba S3 are both cordless robotic pool cleaners for in-ground pools that cover the floor, walls, and waterline, no hoses, no cords. They sit in the same family but pull in opposite directions: the X1 is the muscle, built around raw suction, while the S3 is the lightweight, fine-filtering convenience pick.
Here's an honest side-by-side on the specs that matter, plus what real owners report about each, so you can match the right one to your pool.
| Feature | Aiper Scuba X1 | Aiper Scuba S3 |
|---|---|---|
| Suction | 6,600 GPH (dual jet) | 4,800 GPH |
| Runtime | Up to 180 min | Up to 240 min (ECO) |
| Battery / charge | 268 Wh · ~3.5–4 hr | 10,400 mAh · ~3.5 hr |
| Filtration | Multi-layer, 3μm MicroMesh | Dual-stage 180μm + 3μm ultra-fine |
| Coverage | Floor, walls, waterline | Floor, walls, waterline, shallow |
| Waterline | WaveLine 2.0 (~2 in above water) | Lateral scrub (~2 in above water) |
| Charging | Wireless charging dock | Auto-docks at waterline + phone alert |
| Weight | 40 lbs | 18 lbs (one-hand lift) |
| Rating | 4.0 stars | 4.7 stars |
| Warranty | 2 years | 2 years |

Both robots draw praise for the same core strengths: strong suction on fine sand and silt, effective horizontal waterline scrubbing, and the freedom of going fully cordless. They also share the same limitation, the app disconnects the moment the unit submerges, so there's no live control underwater on either (both can optionally use Aiper's HydroComm accessory).
The clearest real-world difference is handling. The S3 is repeatedly called easy to lift and carry once drained, while X1 owners note it's heavy to pull out and that you lift it onto the dock yourself to charge. S3 owners occasionally find the waterline auto-park inconsistent, and both share a filter caveat: run the ultra-fine 3μm filter for finishing, not for every cycle, since it can clog and cut into battery life.
Choose the Scuba X1 if you want the strongest suction in this pair for a pool that collects heavier debris or fine sand, and you don't mind the extra weight. Its WaveLine 2.0 waterline cleaning and wireless dock are nice touches, and OTA updates mean it keeps improving.
Choose the Scuba S3 if you value easy handling, a longer runtime, the clearest water from its dual-stage filtration, and set-and-forget convenience like waterline auto-docking. For most typical residential in-ground pools, the S3 is the easier day-to-day robot, and it carries a higher owner rating.
Both are genuinely hands-off cordless robots with 2-year warranties and the same underwater app limitation. It comes down to power and debris load (X1) versus weight, runtime, and convenience (S3).

Most Powerful
The power pick: 6,600 GPH dual-jet suction for fine sand, pebbles, and algae, multi-layer filtration down to 3 microns, WaveLine 2.0 waterline scrubbing with dual front PVC brushes, and a wireless charging dock. OTA updates refine its cleaning paths over time. The trade-off is weight (40 lbs) and a manual lift onto the dock to charge. Rated 4.0 stars, 2-year warranty.
Easiest to Handle & Best Filtration
The convenience pick: 4,800 GPH suction with dual-stage 180μm + 3μm ultra-fine filtration for very clear water, up to 240 minutes of ECO runtime, and a ~3.5-hour recharge. At just 18 lbs it lifts with one hand, scrubs the waterline laterally, auto-docks, and alerts your phone when done. Rated 4.7 stars, 2-year warranty.
Neither is strictly better; they're built for different priorities. The X1 wins on raw suction (6,600 vs 4,800 GPH), making it the pick for pools with heavier debris or fine sand. The S3 wins on weight (18 vs 40 lbs), runtime (up to 240 vs 180 minutes), dual-stage filtration, and convenience features like waterline auto-docking, and it carries a higher owner rating (4.7 vs 4.0 stars). For easy handling and clear water, choose the S3; for maximum power, choose the X1.
The S3, by a wide margin. It weighs about 18 lbs and owners describe it as a genuine one-hand lift once drained. The X1 is around 40 lbs and, full of water, is a heavier two-hand haul, and you lift it onto its charging dock yourself. If handling is a priority, the S3 is the easier robot.
Not underwater. Both robots lose their app/Wi-Fi connection the moment they submerge, so you select the cleaning mode before dropping them in and they finish the cycle on their own. Live underwater control requires Aiper's separate HydroComm accessory on either model.
No. Both robots remove physical debris and help circulate the water, but neither sanitizes or balances chemistry. You still need to test and adjust chlorine, pH, and alkalinity alongside using a robotic cleaner.
For most residential in-ground pools, the Aiper Scuba S3 is the easier, more convenient robot, lighter, with a longer runtime, standout 3-micron filtration, and smart waterline docking, and it carries a higher owner rating. Step up to the Scuba X1 if you want noticeably stronger 6,600 GPH suction and WaveLine 2.0 waterline scrubbing for a pool that collects heavier debris, and you're fine with the extra weight. Both are solid, hands-off cordless cleaners with 2-year warranties, so match the strengths to your pool.
