When can submersible pumps or mechanical pool cleaning equipment be used?

The correct answer is that submersible pumps or mechanical pool cleaning equipment can be used only when the pool is empty. This guideline is primarily for safety and operational reasons.

When the pool is empty, there is no risk to bathers, which eliminates the potential for accidents or injuries that could occur if equipment or tools are operated while people are in the water. Additionally, using these devices when the pool is empty helps ensure that the cleaning process is efficient and can be conducted without interruptions.

While one might think using this equipment during lifeguard patrol or while bathers are present could be manageable, it can pose safety hazards or interfere with the lifeguard’s ability to observe swimmers effectively. The presence of operational equipment can create hazards that are unsafe for both the patrons and the operators. Therefore, using pumps or cleaning equipment is restricted to times when the pool is not occupied for the safety of everyone involved.
