2026 verdict
The Aiper Scuba V3 Ultra delivers more of what a pool robot can do in this matchup, and the Aiper Scuba S3 is the mid-tier machine that does the essentials well.
The V3 Ultra wins on warranty (three years against two), on cleaning coverage, adding surface skimming and a shallow-ledge pass to the floor, wall and waterline work both do, and on navigation, with dual-camera AI vision and ultrasonic sensors where the S3 uses WavePath 2.0 with dToF. It also skims for up to 480 minutes and charges on a magnetic wireless dock. The Scuba S3 is the more affordable of the pair, lighter at 18 lbs and still filtering to 3 microns, so it suits an in-ground pool where the floor, walls and waterline are the whole job.

What the differences mean
Cleaning coverage
The Aiper Scuba V3 Ultra adds surface skimming and cleaning of shallow ledges down to 7.9 inches to the floor, wall and waterline work it shares with the Aiper Scuba S3. A pool that gathers floating leaves as well as sunken grit gets one machine instead of two.
Navigation
The V3 Ultra uses two cameras for stereo depth plus an ultrasonic sensor and recognises more than twenty kinds of debris and obstacle. The S3 uses WavePath 2.0 with dToF sensing, which plans a route but does not identify what is in front of it.
Runtime and charging
The V3 Ultra skims for up to 480 minutes and charges on a magnetic wireless dock with no exposed contacts. The S3 runs up to 240 minutes and has no dock, so every cycle ends with lifting it out and plugging in a cord.
Pool size
The V3 Ultra is rated for in-ground pools up to 3,875 sq ft and the S3 up to 1,650 sq ft. On a large pool the S3 needs several cycles where the V3 Ultra finishes in fewer, because its quoted area is measured in the easiest mode.
Warranty and weight
The V3 Ultra carries a three-year warranty and weighs 28.8 lbs; the S3 carries two years and weighs about 18 lbs. The S3 is the easier one-hand lift, while the V3 Ultra commits for longer to the parts that live in chlorinated water.
Which one to buy if
- your pool collects floating leaves as well as sunken debris
The V3 Ultra skims the surface and cleans below it, so you do not need a separate skimmer.
- you have a sun shelf or a shallow ledge
The V3 Ultra works shallow areas down to 7.9 inches with anti-fall sensors, which the S3 does not reach.
- you want the easiest machine to lift out
The S3 weighs about 18 lbs against 28.8 lbs, which matters at the end of every cycle.
- you want the lower outlay for the standard surfaces
The S3 covers the floor, walls and waterline with the same 3 micron filtration for considerably less.
- you want a wireless charging dock
The V3 Ultra sits on a magnetic dock with no exposed contacts, where the S3 has to be plugged in.

What owners say
Aiper Scuba S3 owners describe an easy first run: charge it, drop it in and let it work, with the app handling setup and the modes. The waterline pass draws the most praise, and the sideways JetAssist scrub is called out for the round corners of a steel-frame pool. The fine filter is the other theme, with the ultra-fine layer holding algae and silt and making the water read clear, and the waterline parking plus its app notification save the end-of-cycle fishing. Their complaints are the short parking window, no live control while the unit is submerged, and the absence of a charging dock.
