The 100°C mop-wash cycle is credited with reducing germs and leaving the pads cleaner. It adds a hygiene advantage for kitchens, bathrooms, and other frequently mopped areas.
Pros: Suction and Airflow, Obstacle Avoidance (Robot)
Cons: Streaking / Residue, Solution / Liquid system
Hot-water washing and warm-air drying help keep the mop and debris bag fresher between uses. The system adds useful hygiene, even though floor-level water temperatures are not true sterilization.
Pros: Mopping performance, Overall opinion
Cons: Edge and Baseboard Cleaning (Hard Floors), Price and Value
Electrolyzed water, hot washing and continuous roller cleaning give the S2 unusually strong hygiene features. The system is especially appealing for homes with children or pets.
Pros: Overall opinion, Mopping performance
Cons: Support and Reliability, Price and Value
Hygiene is a core strength: clean and dirty water stay separated, waste remains out of internal pipes, and hot-air drying helps keep the roller sanitary. One strongly negative test disputed...
Pros: Self-cleaning cycle, Overall opinion
Cons: Emptying and Mess Control, Price and Value
Sanitizing-related evidence centered on the heated, hygienic roller system, which reviewers associated with cleaner, fresher mopping rather than independently verified sanitization.
Pros: Overall opinion, Mopping performance
Cons: Price and Value, AI, Smart, App and Automation
One review framed the heated fresh-water washing system as more hygienic, but evidence was limited to station washing rather than verified sanitization.
Pros: Overall opinion, Suction and Airflow
Sanitizing evidence was limited and cautioned that UV light itself does not sanitize quickly during a pass-over.
Pros: Mopping performance, Dried-On Stain Removal
Cons: Map and Path Efficiency (Robot Vacuums), Price and Value
