The S3 wins on navigation (WavePath 2.0 with dToF sensing, obstacle avoidance and auto-parking, where the Aiper Scuba S1 rides WavePath 2.0 inertial navigation alone) and on battery life, 240 minutes against 180. The Scuba S1 is the more affordable of the pair and still covers the floor, walls, waterline and the shallow ledge with the same five modes and a 3 micron dual-layer filter, so it remains the value choice for a typical pool.

What the differences mean

Navigation

The Aiper Scuba S3 adds dToF sensing with obstacle avoidance and automatic parking on top of WavePath 2.0, where the Aiper Scuba S1 uses WavePath 2.0 inertial navigation. In a pool with a ladder, a drain or a light, the S3 routes around them and ends its run at the waterline instead of stopping mid-floor.

Battery life

The Scuba S3 runs up to 240 minutes on a 10,400 mAh pack; the Scuba S1 runs up to 180 minutes. On a larger in-ground pool that is the difference between one full floor, wall and waterline pass and a cycle that ends before the far end is finished.

Brush system

The Scuba S3 uses two active brushes and the Scuba S1 a single active PVC roller. The extra brush helps on the hard, stuck-on film at the waterline and in the cove, while the single roller is lighter and simpler to keep clean.

Which one to buy if

  • the waterline is the chore you want to stop doing by hand
    Aiper Scuba S3

    The Scuba S3 runs a sideways JetAssist pass along the waterline and parks there at the end of the cycle.

  • you want the lowest outlay for a typical in-ground pool
    Aiper Scuba S1

    The Scuba S1 covers floor, walls, waterline and shallow areas with the same 3 micron filtration for less.

  • your pool has ladders, drains or lights to work around
    Aiper Scuba S3

    The Scuba S3 adds obstacle avoidance and automatic parking that the Scuba S1's inertial navigation does not.

  • you want the longest run per charge
    Aiper Scuba S3

    The Scuba S3 runs up to 240 minutes against 180 on the Scuba S1.

What owners say

Owners of the Aiper Scuba S3 describe an easy first run: charge it, drop it in and let it work, with the app guiding setup and the modes. The waterline pass is the favourite, and the sideways JetAssist scrub is singled out for the round corners and curved walls of a steel-frame pool. The fine filter is the other recurring theme, with the ultra-fine layer pulling algae and silt out and making the water read clearer. The waterline parking and its app notification come up as the feature that saves the end-of-cycle fishing, and several owners upgrading from an older Aiper call it a clear step up. Their gripes are the short parking window, no live control while it is submerged, and no charging dock.

Upgrading from the Aiper Scuba S1?

Moving up from the Aiper Scuba S1 to the Aiper Scuba S3 buys a smarter route and a longer run. The S3 adds dToF sensing, obstacle avoidance and automatic parking at the waterline, and it lifts battery life from 180 to 240 minutes with a top-access basket and a 10,400 mAh pack. Coverage is otherwise the same five modes, the same 3 micron dual-layer filtration and the same in-ground rating, at about 1,600 to 1,650 sq ft. If your Scuba S1 already keeps its pool clean, the step is optional; if you want the robot to sense, avoid and park itself, the S3 is the upgrade that does it.

Frequently Asked Questions

Which is better overall: Aiper Scuba S1 or Aiper Scuba S3?

The Aiper Scuba S3 for most in-ground pools, since it adds dToF sensing, obstacle avoidance, automatic waterline parking and up to 240 minutes of runtime. The Aiper Scuba S1 is the more affordable option and still cleans the floor, walls, waterline and shallow ledge with the same 3 micron filtration.

What is the biggest difference between the Aiper Scuba S1 and the Aiper Scuba S3?

Navigation and runtime. The Aiper Scuba S3 uses WavePath 2.0 with dToF sensing, obstacle avoidance and auto-parking and runs up to 240 minutes, while the Aiper Scuba S1 relies on inertial navigation and runs up to 180 minutes.

Do the Aiper Scuba S1 and Aiper Scuba S3 clean the waterline?

Yes, both work the waterline. The Aiper Scuba S3 adds a sideways JetAssist pass and automatic parking at the waterline at the end of the cycle, which makes retrieval easier.

Do the Aiper Scuba S1 and Aiper Scuba S3 work with Alexa or Google Home?

No. Neither the Aiper Scuba S1 nor the Aiper Scuba S3 has smart home integrations, so both are controlled through the Aiper app over Wi-Fi and Bluetooth while the robot is at the surface.

Who should buy the Aiper Scuba S1?

A pool owner who wants the lower outlay and the core surfaces cleaned, the floor, walls, waterline and the shallow ledge, with the same fine filtration as the S3.

Who should buy the Aiper Scuba S3?

An in-ground pool owner who wants the robot to sense and avoid obstacles, park itself at the waterline and run longer between charges.
