Robot vacuums operating in enclosed spaces can increase the level of harmful airborne particles by afactor of six, according to study results released on Thursday.
The air quality risks caused by robot vacuums, while noteworthy, were nevertheless lower than those caused by traditional hand-operated vacuums, said Lin Yu-wen (林瑜雯), an associate professor in Fu Jen University's Department of Public Health, at a press conference held by the Taiwan Society of Indoor Environmental Quality and the Chan-yang Wang Trust.
The study found that hand-operated vacuums caused airborne particle levels to rise to 13 times their base level, while robot vacuums caused a corresponding sixfold rise after 10 minutes' use.
For both types of vacuum, only after 90 minutes did the levels of pollutants return to normal, Lin said. [FULL STORY]
