The technical specifications of pool geysers may vary depending on the specific model and manufacturer. However, here are some common technical characteristics that are often considered when choosing a pool geyser:

1. Pump Power: The pump power determines the height and intensity of the water column created by the geyser. The higher the power, the higher the jet.

2. Jet Height: Geysers can produce water jets of varying heights. The choice depends on the design and effect you want to achieve.

3. Design and Jet Shape: Geysers can create different shapes of water jets, such as vertical columns, cascades, or complex patterns. This depends on the specific model.

4. Materials: Geyser components should be made from corrosion-resistant materials, such as stainless steel or special plastics, to withstand exposure to water and pool chemicals.

5. Lighting System: Some geysers come with integrated lighting, adding a visual effect, especially during the evening or nighttime.

6. Jet Adjustment: The ability to adjust the intensity and direction of the jet allows you to customize the geyser according to your preferences.

7. Control and Automation: Some geysers can be controlled using specialized remotes or automated systems, making them more convenient to operate.

8. Safety Features: Geysers should include safety features like emergency shut-off and accident prevention systems.

9. Installation and Setup: Pay attention to the installation and setup process to ensure the geyser is stable and secure.
