Here is the compliant version organized according to your unified rules (delete brand names, remove exaggerated expressions, remove absolute terms, maintain objective explanations): [Stainless Steel Cordless Cat Water Fountain] This is a cordless water fountain that uses a wireless pump. It is designed to be easy to place anywhere and considers the risk of cats chewing on cords. The tank is made of 304 stainless steel for hygiene. It is designed to resist dirt and be easy to clean daily. [Rechargeable External Battery (Water and Electricity Separation Design)] It features an external rechargeable battery and a structure that separates the water tank from the power unit. The design prevents the power cord from coming into direct contact with water, considering daily use.

It is equipped with sensor detection mode, intermittent mode, and continuous mode (when connected to an adapter). Settings can be adjusted to suit your cat's drinking habits. [Quiet Pump Design] The pump is designed to minimize operating noise, making it easy to use indoors. The noise level is considerate for nighttime and sleeping hours. [Multi-Layer Filter Structure] The multi-layer structure, including filter cotton and pump filters, captures pet hair and dust. It is designed to keep the water clean. [About Cleaning] Stainless steel parts can be washed in a dishwasher (excluding the pump, battery head, and filter tray). Please ensure the temperature does not exceed 60°C during washing.
