Robot vacuums operating in enclosed spaces can increase the level of harmful airborne particles by a

factor 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]
