Maintenance
The Hydro-Wiper requires very little maintenance, and should
provide reliable operation for many years.
The only user replaceable part is the brush. Under normal
conditions, the brush should last many thousands of wipes. If
however the brush does need replacement, these can be obtained
from your supplier or directly from Zebra-Tech Ltd.
