The Aiper Scuba S3 cleans an inground pool's floor, walls and waterline, with mapping to guide its route and fine filtration for dust. Aiper rates it for up to 3 hours per charge. Aiper also describes horizontal waterline scrubbing and an app alert when it returns to the waterline, useful additions if you want easier retrieval.
Who It's For
You have an inground pool and want a battery powered cleaner that scrubs the walls as well as collecting debris from the floor. Aiper rates it for up to 1,600 square feet or 50 feet in length. It suits an owner who wants to schedule cleaning through an app and choose which area gets cleaned. Its fine filter also makes it relevant if dust and sand settle alongside the leaves in your pool.
Look Elsewhere If
You may want a different robot if your pool exceeds 1,600 square feet or extends beyond 50 feet. A long, narrow pool can exceed the length rating even when its total area stays within the area rating. You will also need another way to collect floating leaves and insects, because it does not skim the surface. You may also want a lighter cleaner if lifting it from the water would be difficult, since the robot itself weighs 18.0 pounds.
Where To Buy
Key Features
Battery And Charging. The battery holds 10,400 mAh, with a recharge time of 4 hours. Cleaning time is rated at up to 3 hours per charge. You can schedule cleaning through the app, although the robot still needs charging between battery powered runs. A full clean followed by a recharge means it will spend part of the day out of the water.
Mapping And Cleaning Modes. Aiper describes path planning guided by a dToF sensor, including coverage in irregular pools. The robot has separate floor, wall and waterline modes, so you can target the area that needs work. If most of the debris has settled on the bottom, floor mode lets you direct the cleaning there without choosing a run that includes the walls.
Waterline Scrubbing. Aiper calls its horizontal waterline movement JetAssist and says it is designed to scrub where grime builds up along the water's edge. That gives the waterline its own cleaning action as well as its own selectable mode. If a visible band forms around your pool, you can target that band rather than always asking the robot to clean every area.
Filters And Debris. The main filter is 180 microns, and the fine filter is 3 microns. The MicroMesh filtration captures fine dust and sand, with leaves also among the debris the cleaner collects. The fine layer gives it a way to collect small particles alongside the larger debris held in the main filter.
Brushes And Traction. Active brushes scrub while the robot travels on tracks. The brushes and suction work together to loosen, lift and collect debris. Suction is rated at 4,800 gph. The tracked design handles floor travel and wall climbing, with a supported incline of 15 degrees.

How It Compares
Aiper Scuba V3 Check Price at Aiper
Aiper Scuba V3 is identified as an AI Vision option on Aiper's product page, so choose it if you want vision alongside the advanced mapping the S3 also offers. Its pool size rating and maximum runtime match the S3's, with app scheduling and floor, wall and waterline cleaning shared by both robots, so the vision feature is the reason to choose it for the same pool rather than expecting a longer clean or a larger coverage area.
Aiper Scuba X1 Get the deal at Aiper
Aiper Scuba X1 is the larger pool option in the same Premium tier, with a rating of 2,150 square feet and the same maximum runtime. Choose it if you need that extra coverage and can manage its 24.3 pounds when lifting it out. The S3 weighs 18.0 pounds.
Aiper Scuba S1 Get the deal at Aiper
Aiper Scuba S1 is another Aiper model to look at if longer cleaning time matters more than advanced mapping, because it runs for up to 4.5 hours and uses patterned paths. It shares the pool size rating and app scheduling, so choose it for longer battery powered sessions within the same pool footprint, while the S3 adds mapping and higher suction.
Worth Knowing
Aiper says the cleaner returns to the waterline and sends an app notification when it arrives. You can use the alert to go out and collect it instead of checking the pool repeatedly. The manufacturer's quick water release design sheds water during retrieval, which could make the lift easier as the water drains away. The robot itself weighs 18.0 pounds, so you still lift it out by hand. The Amazon listing describes button activation as well as app control. The retrieval alert uses your phone, even if you start the cleaner with the button.
Frequently Asked Questions
How large a pool can it clean?
Up to 1,600 square feet, with a maximum length of 50 feet, according to Aiper. That rating applies to inground pools, including rectangular, round and freeform layouts.
How long does a charge last?
Up to 3 hours. A full recharge takes 4 hours, so the battery needs time on the charger before you can start another full length cleaning session.
Does it clean walls and the waterline?
Yes. It scrubs both, and you can select a dedicated mode for either area. Aiper describes horizontal movement along the waterline to scrub the band at the water's edge.
Can I use it in saltwater?
Yes. Its compatibility includes saltwater and chlorine pools. Mineral water and pools using ozone or UV treatment are also within the water types supported by this model.
Where do I remove the filters?
From the top. You reach the filters from above when you empty them, without having to turn the cleaner over to reach underneath.
Do I need my phone to start it?
No. The Amazon listing describes button activation as well as app control. The app adds cleaning mode customization and scheduling if you want to set up cleaning from your phone.
Which pool surfaces can it clean?
Vinyl, gunite, fiberglass, tile and pebble are supported. That gives it compatibility with several common inground pool finishes, along with both hard and soft pool walls.
