Aiper Scuba X1 and Surfer S2: six-month owner notes for EcoSurfer S2 buyers

My Aiper Scuba X1 broke down twice in just over six months. Even between failures, retrieving it and washing sand out of the filter have been a struggle.

A black Aiper robotic pool cleaner submerged in clear swimming pool water with water ripples on the surface.

I started using it in February, and by August—just over six months—it had broken down twice.

The problem was the same both times: one motor stopped working in the water, and the machine automatically shut down after sinking to the bottom.

I don't even dare imagine what will happen once it is out of warranty.

Even when this thing isn't broken, it is still a huge headache.

The machine can only be hooked from a particular angle. When the water is cloudy, I spend ages trying to hook it and still cannot get it out.

The machine is extremely heavy because a lot of water remains inside it. Whenever I lift it out, that water carries debris back into the pool. It feels like all that filtering achieved nothing.

The coarse filter, fine filter, and the machine are not sealed tightly against one another, so particles can escape.

The fine filter is made of felt. Sand and dust become extremely difficult to wash out, and if I scrub it hard, it basically pills and is ruined after three or four uses.

The intake opening is extremely small. It cannot suck in even slightly large leaves, so I have to scoop them out by hand afterward.

Did whoever developed this product actually use it themselves?

However, the Surfer S2 is still very good. I have not charged it since buying it. It can run all day using only solar power.

Before You Buy

Models in your region

The source identifies the tested machine as an Aiper Scuba X1, not a Scuba X1 Pro Max, and also mentions an Aiper Surfer S2. The official US and EU pages identify the Scuba X1 as a submerged floor, wall, and waterline cleaner, while the EcoSurfer S2 is a separate surface skimmer. The owner does not give a full model number or establish that the tested S2 matches every current regional bundle.

What the six-month account establishes

The owner reports two similar failures during more than six months of use: one motor stopped working in the water, after which the robot sank and shut down. The cause has not been confirmed by a motor teardown, and this single-machine account cannot establish a failure rate for the model.

That experience is relevant when evaluating warranty and service risk, but it does not establish what will happen after coverage expires. Buyers should confirm the applicable regional warranty, repair route, and replacement-part terms for their exact Scuba X1 before purchase; those terms are not supplied here.

Retrieval and debris handling

The owner's main handling complaint is that the robot must be hooked from a particular angle and becomes difficult to retrieve in cloudy water. They also describe it as very heavy because water remains inside, with water and debris flowing back into the pool during lifting. These are reported operating conditions, not official weight or retrieval specifications.

For a buyer, the practical question is whether the intended pool can be kept clear enough to locate the robot and whether lifting equipment or a convenient retrieval position is available. The Scuba X1 cleans underwater floors, walls and waterlines. The hook angle and retained water described here are observations from the owner’s retrieval attempts.

Filter maintenance and leaf size

The owner reports particles escaping between the coarse filter, fine filter, and machine, a felt fine filter that traps sand and dust, and damage after three or four forceful scrubbing sessions. The official US and EU descriptions instead specify a removable filter basket with a MicroMesh fine filter, recommend rinsing the fine filter after every use, and mention periodic replacement; they do not confirm the owner's specific sealing or durability result.

The owner also says the intake cannot handle slightly large leaves, requiring a second manual cleanup. This owner’s account of more than six months of use suggests buyers with leafy pools should treat debris-size performance as an unresolved point and confirm the current filter and intake design rather than assuming the official filter description guarantees leaf pickup.

Scuba X1 versus EcoSurfer S2

The owner's positive comment about the Surfer S2 concerns a different task: surface collection. Current US and EU information names that product the Aiper EcoSurfer S2, describes a solar-powered surface skimmer with a 150-micrometre filter and app control, and lists 35 hours with adapter charging; solar operation depends on available light. It does not replace a submerged cleaner.

The owner's statement that their S2 ran all day without charging is therefore a unit-and-condition-specific observation, not a universal runtime promise. Consider the EcoSurfer S2 when the priority is collecting surface debris, and the Scuba X1 when submerged floor, wall, or waterline cleaning is required; the two products serve different cleaning roles.
