Animals are automated cleaning machines.  They are covered with specialized hairs and spikes that can remove and even prevent particles from landing in the first place, using methods that have no modern equivalent.  In this talk, I discuss how animals groom, from labradors to tigers.  We use high-speed and time-lapse videography to show how dogs shake off water, eyelashes deflect air flow, and cats keep their fur clean.  Special attention is paid to using theoretical models and advances in 3D printing to discovering new principles in soft, self-cleaning systems.
