mark, slotting it into the vacuum, then turning clockwise to
lock it in place.
Cleaning the Rollers
Follow these instructions when inspecting and cleaning the
Rollers to ensure optimum performance. Inspection and
cleaning should be performed regularly. Before removing
the roller, remove the accessory from the vacuum to avoid
accidental damage.

Motorized Mini-Brush and Carpet brush rollers must be removed and cleaned
separately. As there are electrical components and bearings in these rollers, do not
wash them with water.
