Maintenance 'Bots (Matrix)

Spiders perform a variety of tasks, from keeping things clean to performing repairs on other robots.  In general, they take no notice of anything other than broken machines.  They scurry around anywhere there are machines to maintain, often working in large groups to complete tasks more efficiently.   Spiders are merely one type in an entire class of custodial robots that tend to the Leviathan and its sub-parts.
