Bromeliad

Bromeliads are Klis automata installed on the exteriors of spires and skyscrapers. They consist of a central stalk, two to three feet in height. The stalk contains all of the construct's clockwork and vacuum tubes, wrapped in a concentric series of rattan canes and encased in a steel shell. The ends of the canes emerge from the base of the stalk, where, magically animated to cilia-like mobility, they act as the bromeliad's propulsion.
From the central stalk, anywhere from three to nineteen arms emerge. A bromeliad's arms are usually made of steel jacketed in concentric copper rings, and have many, many joints. The end of each arm has a different tool: multi-articulated grasping fingers, brushes, oil hoses, suckers, abrasive stones, and syringes are all common.
The stalks of bromeliads are generally assembled during a building's construction so that their animating enchantment can be linked to the architecture itself; they require no sensory equipment, as they are able to automatically detect anything touching the building's superstructure. Arms and implements are added later according to the desired function; bromeliads fulfill a variety of roles, from custodial and maintenance to gathering samples of pigeon blood for the biologically-minded wizard. With their unerring ability to locate and follow intruders, bromeliads make for excellent security. However, they aren't really designed for combat and so are typically placed on a structure's exterior as surveillance while more-robust constructs provide muscle indoors.
While a bromeliad's ability to track and tenaciously pursue an intruder is potent (and unnerving), they are by no means foolproof security, and enterprising thieves have been finding ways to circumvent the constructs since their invention. Heists on bromeliad-protected buildings must be carried out with minimal contact to the floors, walls, or ceiling, and thus tend to involve levitation, transformation into flies, freezing a layer of ice over the floor and skating in, or, in one memorable instance, swimming up an elevator shaft in a magically-animated globe of seawater.
