Vacuum cleaner-wielding superheroes are about to be taken a lot more seriously. Professional climber Sierra Blair-Coyle was the guinea pig for a daring proof of power: she crawled up the side of a 33-story building in South Korea using two vacuum cleaners.
The feat was a demonstration for LG’s newest CordZero vacuum and its powerful battery. The batteries provided enough suction to let Blair-Coyle live out many a nerd’s dream (with a safety harness, of course). Try doing that with your fancy Dyson vacuum.
