Standard
edge cleaning is provided on the left side of cleaner to remove surface dust and litter.
Adjustment for
carpet pile height
The cleaning of carpet and rugs
takes place at the nozzle. The adjustment lever on the
front of the cleaner is used to raise and lower the nozzle to three different self-adjusting
ranges.
It is recommended that the BARE FLOOR/LOW range be
used on all carpet types.
However, on dense plush or shag carpet, the cleaner may be difficult to push. In this case, reposition the adjustment lever on the PLUSH or DEEP PILE setting.
