To maintain cleaner performance at its best you need
to replace the brushes as soon as one of the wear
indicators is reached (even if the blade wear is not
even). It is recommended that you replace the brushes
when the rubber is worn down to the top of the wear
indicator (or every two years, whichever comes first).
To replace a worn brush:
1.
Lift the cleaner to a vertical position so that the handle
is up.

2.
Separate the edges of the brush and undo the tabs.
Remove the worn brushes.
