As the Bandit has no mechanical components it is practically maintenance free in itself.
However, the system is subject to the typical lifespan of the back-up battery and the degradation of the food grade glycol within the HY3 fog fluid cartridge.

HY3 Fog cartridge only requires changing every 4 years
