Whiz Gambit, the advanced 3-in-1 cleaning, disinfection, and air-purifying robot, has joined the Hong Kong Customs and Excise Department to enhance health protection for visitors at all Hong Kong borders, including Hong Kong International Airport, Hong Kong–Zhuhai–Macao Bridge Port, Shenzhen Bay Port, Lo Wu Port, Lok Ma Chau Port, Man Kam To Port, and Custom House.

The COVID-19 pandemic has highlighted the importance of cleanliness and hygiene in preventing the spread of diseases. However, many people still confuse these two terms, leading to inadequate practices. Cleanliness focuses on the physical appearance of surfaces, while hygiene is driven by practices and measures taken to maintain health and prevent disease spread, even when a surface appears clean. Understanding the factors that affect the survival of pathogens on surfaces is crucial in developing effective cleaning protocols.

While a visually clean environment may give the impression of being hygienic, it does not necessarily guarantee actual cleanliness. To ensure a truly clean and safe environment, it is essential to adopt a scientific approach to measure surface cleanliness. Among various methods, ATP bioluminescence testing stands out as the preferred choice for its speed, reliability, and cost-effectiveness.
