The Aiper Scuba S1 Pro has a main filter and a finer layer for microscopic debris, with both reached from the top. It also scrubs the floor and walls, using active brushes and tracks. Aiper rates it for inground pools up to 2,150 square feet, with app scheduling and up to 3 hours of cordless cleaning.
Who It's For
This cleaner suits an inground pool owner who wants to collect leaves and finer debris while also having the walls and waterline scrubbed. Its fine filter could be useful if dust is a regular part of your cleanup. The combination of mapping and app scheduling also suits someone who wants to choose when cleaning happens. Rectangular, round and freeform layouts are all covered, so curved sides do not exclude your pool from the shapes it supports.
Look Elsewhere If
You may want a different robot if your pool exceeds 2,150 square feet or is longer than 66 feet. It does not skim floating leaves from the open water, so you would still need a net or another way to collect those leaves yourself between cleaning sessions. The Amazon listing sells it as a renewed unit. You may also want a different robot if your pool needs continuous cleaning throughout the day without pauses to recharge.

Key Features
Fine Filtration. Aiper specifies a main filter of 180 microns alongside a fine filter of 3 microns. The finer layer gives this model a way to collect microscopic debris in addition to larger material. If dust settles on your pool floor between cleanings, that filter is particularly relevant. The debris compatibility includes fine, medium and large material. That gives an owner dealing with leaves and smaller particles a reason to use both levels of filtration.
Horizontal Waterline Cleaning. The Amazon listing names horizontal waterline cleaning. The floor and walls are also within its cleaning coverage. If dirt collects around the pool's edge at water level, this is the feature that addresses that location. Active brushes provide the scrubbing action, while tracks are the robot's means of moving across the pool surfaces.
Mapping And Modes. Advanced mapping guides the cleaning route, and the available modes cover the floor, walls and waterline. App scheduling adds control over when a run starts. You can use the scheduling from your phone, so starting a run does not have to be a separate task each time you want the pool cleaned.
Battery And Charging. Runtime reaches up to 3 hours, with a full charge taking 4 hours. That charging time matters if you want another run on the same day, because the battery needs time to refill after cleaning. The cordless design removes a power cable from the pool during operation. Battery capacity is 7,800 mAh.
Surfaces And Traction. The compatibility covers vinyl, gunite and fiberglass, as well as tile and pebble finishes. Tracks support travel across those surfaces, with active brushing for cleaning contact. Aiper also includes hard and soft walls in the compatibility data. It also works on inclines up to 15 degrees. If your floor slopes toward a deeper section, that incline rating applies to the surface the tracks must travel over, alongside compatibility with the pool's finish.

How It Compares
Aiper Scuba S1 Get the deal at Aiper
Aiper Scuba S1 is the sibling to choose if your pool fits within 1,600 square feet and you want app scheduling alongside a longer cleaning session from a charge. It runs for up to 4.5 hours, although its patterned navigation differs from the advanced mapping of the S1 Pro, so the longer runtime comes with a different approach to covering the pool.
Aiper Scuba X1 Get the deal at Aiper
Aiper Scuba X1 suits someone who wants a higher suction flow rating while keeping the same stated pool area of 2,150 square feet and the same floor, wall and waterline coverage. Its flow rating reaches 6,600 gph, although the heavier body means more weight to lift when you collect it, so that difference matters if retrieval is already difficult for you.
Aiper Scuba X1 Pro Max Get the deal at Aiper
Aiper Scuba X1 Pro Max adds surface cleaning to the underwater cleaning zones, so choose it if you want floating debris collected as part of the robot's work too. It also runs for up to 5 hours, giving an owner who needs longer sessions a reason to choose it beyond the extra cleaning zone, particularly for a larger pool.
Worth Knowing
Aiper rates suction flow at 4,800 gph. You reach the filters from the top of the body. Water compatibility includes mineral systems and pools treated with ozone or ultraviolet light, as well as conventional chlorine treatment. At 20.9 pounds, it falls in the Medium weight class. The cordless design leaves you handling the robot itself when you take it out for charging, so the person lifting it still needs to be comfortable with that weight after each completed cleaning session.
Frequently Asked Questions
How do I reach the filters?
From the top of the robot. The filtration combines a main filter for collected debris with a finer layer for microscopic material, both within the body of the cleaner.
How long does it run before charging?
Up to 3 hours. A full recharge takes 4 hours, so using a full battery means waiting longer to recharge than the robot spent on that cleaning session.
Can I schedule cleaning from my phone?
Yes. App scheduling is included, so you can set cleaning times from your phone. The robot combines that scheduling with advanced mapping for its route through the pool.
How heavy is it to lift?
20.9 pounds. You lift that body out when you collect the cleaner, so the weight remains part of each retrieval even though operation itself is cordless.
Can it work on a sloping floor?
Yes. The working incline is rated at 15 degrees, so a gently sloping pool floor falls within its capabilities when the slope stays inside that rating.
Does it clean the walls and waterline?
Yes. Both are included alongside floor cleaning, and the Amazon listing names horizontal waterline cleaning.
Can I use it in a saltwater pool?
Yes. Saltwater compatibility is included for this inground cleaner, along with chlorine and mineral water compatibility, so a salt system does not exclude it from your options.
