Original Accessory part - P1 3-Micron Inner-Layer Replacement Filter Basket

Maintain ultra-fine debris collection and clear pool water with the ECOVACS ULTRAMARINE P1 Inner-Layer Filter Basket.

Ultra-Fine 3-Micron Filtration

The inner-layer filter features an ultra-fine 3-micron mesh designed to capture small particles that may pass through a standard coarse filter. This includes fine debris such as sand and pollen.

Dual-Layer Filtration System

The inner filter is designed to fit inside the ULTRAMARINE P1’s 180-micron outer filter basket. The outer layer captures larger debris, while the inner layer targets much finer particles.

Together, the two layers allow the P1 to collect more than ten types of debris, ranging from leaves, twigs and insect remains to sand and pollen.

Supports Cleaner, Clearer Pool Water

By trapping fine particles inside the filtration system, the inner basket helps prevent collected debris from being circulated back into the pool. This supports cleaner-looking water and more thorough filtration during each cleaning cycle.

Works with 4800GPH UltraPure Suction

The inner filter basket works together with the P1’s powerful 4800GPH UltraPure Suction system. Water and debris are drawn into the filtration basket, where the dual-layer system separates both large and fine particles from the cleaning flow.

Removable and Easy to Clean

The inner filter can be removed from the outer basket for separate cleaning. This makes it easier to rinse away trapped fine particles and maintain unrestricted water flow through the filter material.

Helps Maintain Cleaning Performance

A dirty or clogged filter can restrict water flow and reduce cleaning effectiveness. Regular cleaning helps the P1 maintain reliable suction, debris collection and wall-climbing performance.

Designed for the ULTRAMARINE P1

This inner-layer filter basket is designed specifically for the ECOVACS ULTRAMARINE P1 Robotic Pool Cleaner. It can be used as a replacement for a worn or damaged filter or kept as a spare for continued pool maintenance.

CLEANING AND MAINTENANCE

• Switch off the ULTRAMARINE P1 and remove it from the pool.
• Press the button on the front of the cleaner to open the filter-basket cover.
• Remove the complete filter-basket assembly.
• Empty any collected debris from the outer basket.
• Remove the 3-micron inner filter from the outer basket.
• Thoroughly rinse the inner and outer baskets separately using clean water.
• Allow the filter mesh and basket to air-dry completely.
• Insert the inner filter into the outer basket and reinstall the complete assembly.
• It is recommended that the filter basket be cleaned after every use.

WHEN TO REPLACE THE FILTER

For optimal filtration performance, ECOVACS recommends replacing the 3-micron inner filter after approximately 30 uses. Replace it sooner if:

• The filter material is torn or punctured
• The seams begin separating
• The filter remains blocked after thorough rinsing
• Water flow or suction performance does not improve after cleaning
• The filter is damaged or no longer fits securely inside the outer basket
