Seasonal Cleaning Recommendations
| Season | Recommended Frequency | Cleaning Method |
|---|---|---|
| Summer | Every 2-3 weeks | Primarily removes seaweed and small shrimp. Requires high frequency due to rapid growth. |
| Autumn | Every 4-6 weeks | Critical for northern seas: Must thoroughly clean during early mussel attachment (starts in September). |
| Winter | Inspection-dependent | Requires extra monitoring to prevent sudden mussel outbreaks. |
Fouling-Level Cleaning Recommendations
| Fouling Severity | Recommended Frequency | Cleaning Method |
|---|---|---|
| Light Fouling (Early Stage) | Every 2 weeks | Single high-speed robot pass |
| Moderate Fouling (Mid Stage) | Weekly | Single high-speed robot pass |
| Severe Fouling (Late Stage) | Continuous cleaning | Multiple low-speed passes with focused cleaning on stubborn areas |
