of
the
pump used
in
the
scrubber
(on
models equipped with awriliary pump)
are
suitable for use
with most cleaning chemicals. But it is susceptible to
chemical attach from some cleaning substances, such
as
hydrocarbon solvents and chlorinated bleaches. These
non-
compatible materials are not of the type normally used for
cleaning.
