Aircraft maker Boeing has designed an airplane bathroom that gives itself a cleaning after passengers’ visits.

Boeing’s self-scrubbing lavatory works by using ultraviolet (UV) light to zap “99.99% of pathogens” crawling on the bathroom surfaces. To ensure a truly thorough sanitization, the system lifts the toilet cover while the lights are engaged. The entire UV scrub-down takes about three seconds, the Chicago, Ill. the firm says.

“The UV light destroys all known microbes by literally making them explode,” said Boeing engineer Jamie Childress in a statement.
