Our score comes from manufacturer specs, professional reviews, and owner reports. It is not a hands-on lab test. ## The verdict The Scuba S3 is Aiper's answer for people who want clearer water, not just a clean floor: the replaceable 3-micron insert is its standout. At about $700 it competes directly with the AquaSense 2; Beatbot has the edge on coverage per charge and warranty, Aiper on filtration and weight. ### What we like - Dual-stage filtration with a 3 µm ultra-fine insert captures dust and sand that 150–180 µm baskets miss - Light at 18 lbs — one of the easier cordless robots to lift out - Waterline scrubbing reaches about 2 inches above the water line - Auto-docking at the waterline with a phone alert ### Watch out for - Brand-new listing (~110 Amazon reviews) — no multi-season track record - Warranty term isn't stated on the listing; confirm with Aiper before buying - Live app control isn't available underwater; scheduling and status only ## Score breakdown Cleaning 8.6 Convenience 8.8 Build & reliability 8.2 Value 8.4 Reach: Not stated · Up to 4 hr (Eco mode) ## Scuba S3 specs | Brand | Aiper | | --- | --- | | Type | Cordless | | Pool type | In-ground | | Cleans | Floor · Walls · Waterline | | Runtime | Up to 4 hr (Eco mode) | | Rated reach | Not stated | | Power | Rechargeable lithium battery (10,400 mAh) | | Filtration | 180 µm mesh + replaceable 3 µm ultra-fine insert | | Navigation | Smart route-optimizing sensors | | App control | Yes | | Weight | 18 lbs | | Warranty | Not stated on the listing — confirm before buying | | Price tier | $$ Mid-range ($500–$1,000).

Specs are compiled from manufacturer listings and independent reviews and may change between production runs. Pool robots are re-listed and re-badged often, so confirm on the Amazon page before buying. The Aiper Scuba S3 is a cordless in-ground pool robot built around cleaner water rather than the longest feature list. It’s light at 18 lbs, ships with dual-stage filtration (a 180-micron mesh plus a replaceable 3-micron ultra-fine insert), scrubs the waterline and parks itself at the surface with a phone alert. It costs about $700 on Amazon and has a rating near 4.8 stars on a small base of about 110 reviews. ## Who the S3 is for (and who should skip it) It’s for you if you’re sensitive to cloudy water, fine sand or pollen and want a robot that filters down to 3 microns, and if you want a cordless robot you can lift out with one hand. The waterline scrub reaches about 2 inches above the water line, per the listing, and the robot travels laterally along the waterline at a steady pace rather than bobbing up and down. Skip it if you have an above-ground pool (it’s marketed for in-ground), if you want a stated coverage rating or a published warranty term (the listing doesn’t give either), or if you want a longer track record. The [Scuba S1](https://robotpoolcleanerguide.com/pool-robots/aiper-scuba-s1/) has a much larger review base. ## Filtration Aiper’s two-stage design is the headline: a 180 µm mesh catches leaves and bigger debris while the optional 3 µm ultra-fine insert captures dust, sand and microscopic particles. Fine filters clog faster, so expect to rinse them more often. We explain when ultra-fine filtration is worth the maintenance in [filtration microns explained](https://robotpoolcleanerguide.com/posts/robotic-pool-cleaner-filtration-microns-explained/). ## Cleaning and navigation The S3 uses built-in sensors to build a route from the pool’s contours, with dual brushes for fewer passes. The listing describes it methodically covering the whole floor, including freeform and uneven surfaces. Auto-docking brings it to the waterline after the cycle and waits for 10 minutes while sending a notification. ## Battery and app The listing gives a 10,400 mAh battery and up to 4 hours in Eco mode, but doesn’t state a rated coverage area. The app handles scheduling (weekly plans), mode changes and status. We’d call the runtime comfortable for typical pools; on very large pools, see our guide to [coverage ratings](https://robotpoolcleanerguide.com/posts/robotic-pool-cleaner-coverage-ratings-explained/). ## Reliability and warranty The S3 is a new listing with about 110 reviews, so there’s no multi-season record. The Amazon page gives the warranty as “limited” without a term (Aiper’s S1 listing states 2 years), so confirm the S3 term before you buy. ## Bottom line The S3 is the best pick here if water clarity is your priority. At about $700 it competes with the [AquaSense 2](https://robotpoolcleanerguide.com/pool-robots/beatbot-aquasense-2/); the Beatbot has more stated coverage and a published 3-year warranty, while the Aiper has finer filtration and a lighter body. Our [head-to-head](https://robotpoolcleanerguide.com/posts/beatbot-aquasense-2-vs-aiper-scuba-s3/) goes through the differences in detail.

It has dual-stage filtration: a 180-micron mesh for leaves and larger debris and a replaceable 3-micron ultra-fine insert that captures dust, sand and fine particles. Most competitors ship with 150–200 micron baskets only. ### How long does the S3 run? The listing says up to 240 minutes (4 hours) in Eco mode, with standard modes giving enough power for a deep clean on one charge. The battery is listed at 10,400 mAh. It doesn't state a rated coverage area, so we don't either. ### Does the Scuba S3 work for above-ground pools? The listing title says "for All Inground Pools", so it's marketed for in-ground pools. For above-ground pools see the Aiper Seagull SE or Dolphin Nautilus AG. ### Can I control the S3 from my phone while it is in the pool? Not live. The listing notes that live app control isn't supported while the robot is underwater. You can schedule weekly cleanings and see battery, logs and status. ## Sources - [amazon.com](https://www.amazon.com/dp/B0HDC7Q945?tag=room4205-20) Not sold yet? ## Alternatives to the Scuba S3 ![Wybot C2 Vision](https://robotpoolcleanerguide.com/_astro/wybot-c2-vision.BhxhGf8J_Z2pkvVH.webp) ### [Wybot C2 Vision](https://robotpoolcleanerguide.com/pool-robots/wybot-c2-vision/) 8.3 - Cordless - Up to 3 hr - Floor + Walls + Waterline Buyers who want camera-guided cleaning that concentrates on dirty areas, with custom routes, at a mid-range price. $$$$ Mid-range Price tier: Mid-range, $500–$1,000 today's price on Amazon [Check price on Amazon](https://www.amazon.com/dp/B0H8YD3QYS?tag=room4205-20)[Read the full review](https://robotpoolcleanerguide.com/pool-robots/wybot-c2-vision/) ![Beatbot AquaSense 2](https://robotpoolcleanerguide.com/_astro/beatbot-aquasense-2.C3q1Ho24_kyqSL.webp) ### [Beatbot AquaSense 2](https://robotpoolcleanerguide.com/pool-robots/beatbot-aquasense-2/) 8.7 - Cordless - Up to 4 hr - Floor + Walls + Waterline Most in-ground pool owners who want a true cordless robot that cleans the floor, walls and waterline and parks itself at the surface. $$$$ Mid-range Price tier: Mid-range, $500–$1,000 today's price on Amazon [Check price on Amazon](https://www.amazon.com/dp/B0HBB2ZJPQ?tag=room4205-20)[Read the full review](https://robotpoolcleanerguide.com/pool-robots/beatbot-aquasense-2/) ![Beatbot Sora 10](https://robotpoolcleanerguide.com/_astro/beatbot-sora-10.rnAw9NlE_2qzeXu.webp) ### [Beatbot Sora 10](https://robotpoolcleanerguide.com/pool-robots/beatbot-sora-10/) 8.5 - Cordless - Up to 5 hr - Floor + Walls + Waterline Buyers who want a waterline-cleaning cordless robot from a premium brand without paying $800 or more. $$$$ Budget Price tier: Budget, under $500 today's price on Amazon [Check price on Amazon](https://www.amazon.com/dp/B0GSVTQK33?tag=room4205-20)[Read the full review](https://robotpoolcleanerguide.com/pool-robots/beatbot-sora-10/) [Compare all 15 robots →](https://robotpoolcleanerguide.com/pool-robots/) ## Helpful guides [Top picks ### The 7 Best Robotic Pool Cleaners of 2026: Ranked by Pool Type, Budget & Features The best robotic pool cleaners of 2026, ranked: Beatbot AquaSense 2, Dolphin Nautilus CC Plus, Beatbot Sora 10 and more.
