The Beatbot AquaSense 2 and the Aiper Scuba S3 are the two cordless robots we’d compare most often at the $700–$850 price point. They clean the same three surfaces, they park at the surface and they have apps. The differences are in the details: stated coverage, filtration, weight and warranty. Here’s how they stack up. Both are 2026 listings with small review bases (about 60 and 110 reviews), so this is a spec-sheet comparison backed by [how we research](https://robotpoolcleanerguide.com/how-we-research/), not a long-term durability verdict.

## Cleaning

Both robots plan routes from sensors rather than bouncing randomly, both climb walls and both scrub the waterline. The S3’s waterline scrub is described as a lateral sweep at a steady pace that reaches about 2 inches above the water line; the AquaSense 2’s listing describes waterline cleaning without that detail. Neither skims. If you want the surface cleaned too, look at the [AquaSense 2 Ultra](https://robotpoolcleanerguide.com/pool-robots/beatbot-aquasense-2-ultra/) or add a [solar skimmer](https://robotpoolcleanerguide.com/posts/robotic-pool-skimmer-vs-vacuum-robot/).

## Filtration

This is the S3’s strongest point. Its dual-stage system pairs a 180 µm mesh with a replaceable 3 µm ultra-fine insert that captures dust, sand and fine particles. The AquaSense 2’s listing doesn’t give a micron rating for its fine-mesh basket. If your complaint is cloudy water or fine dust, the S3 is built for it. [Filtration microns explained](https://robotpoolcleanerguide.com/posts/robotic-pool-cleaner-filtration-microns-explained/) covers the trade-off: finer filters need more frequent rinsing.

## Weight and handling

The S3 weighs 18 lbs. The AquaSense 2 is about 12 kg (roughly 26 lbs) on the listing. Both park at the surface so you don’t have to reach the bottom of the pool, but you do still lift the robot out when it’s full of water. If lifting is a concern, the S3 has the edge. The AquaSense 2’s SmartDrain feature releases internal water to lighten the lift.

## Coverage and runtime

The AquaSense 2’s listing states coverage up to about 3,230 sq ft. The S3’s listing doesn’t give a coverage figure, though its battery is similar in size and Eco mode is rated for up to 4 hours. For a typical pool (500–800 sq ft of floor) either is plenty; for a large pool, the stated rating gives the AquaSense 2 a clearer case. See [coverage ratings explained](https://robotpoolcleanerguide.com/posts/robotic-pool-cleaner-coverage-ratings-explained/).

## Warranty and track record

Beatbot’s table lists a 3-year warranty for the AquaSense 2. The S3 listing says “limited” with no term, though Aiper’s S1 listing states 2 years. Because both robots are new, the warranty matters more than usual.

## Which one should you buy?

Buy the AquaSense 2 if your pool is large, you want the longest warranty, or you have an above-ground pool.

Buy the Scuba S3 if water clarity is your main goal, you want the lighter robot, or you want to save $100–150 and have an in-ground pool.
