Pull-out Water Gun:The most classic and traditional style, water is propelled by manually pulling a piston to generate air pressure.

Pressure Water Gun: Water is forcefully propelled by repeatedly pulling the piston to pressurize the internal water tank. It has a long range and high water pressure, but is heavier when full, requiring some effort. Suitable for older children or adults.

Electric Water Gun: Contains a built-in battery and pump, enabling automatic water intake and continuous electric firing with a single button. It’s effortless and provides sustained firepower. Some models also feature sound and light effects and a pulse function, making it a popular choice for summer water fights.
