Solar skimmers are the simplest pool robots to understand: they float, skim leaves, pollen and bugs from the water surface and recharge from the sun. The two we track, the Betta SE Plus and the Aiper EcoSurfer S2, cost about the same and look similar on paper. The differences are in filtration, smart features and owner track record. A skimmer only handles the surface, so if you also want the floor and walls cleaned, you need a vacuum robot too; see [skimmer vs vacuum robot](https://robotpoolcleanerguide.com/posts/robotic-pool-skimmer-vs-vacuum-robot/).

## Filtration

The EcoSurfer S2’s 150 µm filtration captures finer debris than the Betta’s 200 µm basket; the Betta’s basket is described as extra large and fine-mesh, so it holds more. For pollen season, finer filtration helps; for heavy leaf fall, capacity matters more. See [filtration microns explained](https://robotpoolcleanerguide.com/posts/robotic-pool-cleaner-filtration-microns-explained/).

## Control and features

The EcoSurfer S2’s app starts and stops the robot, sets schedules, steers it, tracks history and sends blockage alerts. The Betta uses a wireless remote and automatic cleaning. The EcoSurfer also holds a 3-inch chlorine tablet in an adjustable dispenser; the Betta doesn’t. If you care about smart features, the Aiper has them.

## Reliability

The Betta’s 4.5 stars across roughly 3,000 reviews beat the EcoSurfer’s 4.3 across about 2,400, and Betta’s design dates to 2023. The EcoSurfer S2 offers a 24-month product-care term against the Betta’s 1-year warranty.

## Which one should you buy?

Buy the Betta SE Plus if you want the best-reviewed skimmer, a big basket for leafy pools and a simple remote.

Buy the EcoSurfer S2 if you want app scheduling, finer filtration, a chlorine dispenser and a longer coverage term.

Then pair it with a vacuum robot from our [best robotic pool cleaners of 2026](https://robotpoolcleanerguide.com/posts/best-robotic-pool-cleaners-2026/).

## Frequently asked questions

### Which solar pool skimmer is better, the Betta SE Plus or the Aiper EcoSurfer S2?
The Betta SE Plus has the stronger owner record (4.5 stars, about 3,000 reviews). The EcoSurfer S2 has more features: app control, finer filtration and a chlorine dispenser. Pick the Betta for reliability and the Aiper for smart features.

### Do solar skimmers work when it's cloudy?
Yes, with a backup adapter. The Betta lists over 30 hours of operation with adapter charging; the EcoSurfer S2 lists up to about 35 hours on an adapter charge.

### Can a skimmer replace my vacuum robot?
No. Skimmers only clean the water surface; leaves that sink, dirt and algae need a floor and wall robot or manual vacuuming.

### Do they work in salt pools?
Both list salt-chlorine-tolerant motors: the Betta describes twin SCT motors and the EcoSurfer S2 describes twin salt chlorine tolerant motors.
