To demonstrate the suction power of its new CordZero canister vacuum cleaner, LG had professional rock climber Sierra Blair-Coyle take part in a one-of-a-kind stunt. The tech company removed her from her natural element and tasked her with ascending the side of a 33-story office building in South Korea.

Harnessed in for safety precautions, her only caveats were that she had only 40 minutes to do it and any climbing equipment would not be her own. Instead, a pair of CordZero vacuums were strapped to her back, their nozzles swapped out for suction cups.

Blair-Coyle relied on her own climbing abilities to do the brunt of the work, needing only to stop midway through her ascent to swap out each vacuum's set of lithium-ion batteries.

Meanwhile, Dyson is building better hair dryers.
