A jacuzzi swim spa pool is a multifunctional bathtub system that combines constant-temperature swimming and hydrotherapy massage functions. It features the linear lanes and constant-current system of a standard swimming pool for swimming exercises, along with massage features similar to those found in a jacuzzi, such as water jets, water-air mixing nozzles, and a supportive seat.

"Draining frequency" isn't a one-size-fits-all standard; it depends on the specific situation. Generally, professionals recommend draining and cleaning the pool every three to four months. However, the specific frequency is affected by the following factors: 1. Frequency of use 2. Number of users 3. Maintenance and management level 4. Local water quality and environment 5. User's physical condition
