Octowasher

Octowashers are an enemy in the Octo Expansion. They are Octarian machines, composed of two circular fans placed horizontally one over the other, with a spinning torrent of ink between them. The top fan has two lamps that serve as the Octowasher's eyes, similar to Flooders. It should be noted that stationary Octowashers dimly flash orange while moving ones flash yellow.

Gameplay
Octowashers are usually found on ride rails and most of them are stationary, though a few will move along the rail towards Agent 8. Touching them will immediately break Agent 8's current armor or splat them if they are in recovery mode, and will also knock them off any ride rails they are on (usually causing a splat from the resulting fall).

Etymology
From 'octo' (short for 'octopus') and 'washer'.
