Abstract: A surface cleaning apparatus includes a fluid delivery system and a recovery system, and is operable in a plurality of user-selectable cleaning modes, including at least a wet vacuuming mode and a dry vacuuming mode. The fluid delivery system has a fluid dispenser that may comprise a spray manifold for wetting a brushroll. The recovery system includes a tank that may have a baffle to separate liquid and/or debris from a working airstream. Operating parameters of the apparatus may be automatically adjusted based on a detected floor type. The apparatus can dock with a tray for recharging and/or self-cleaning.
