| 1. A hand-held motorized household cleaning apparatus comprising:
a housing;
a battery located in the housing;
a motor located in the housing and connected to the battery;
an output drive shaft powered by the motor;
a cleaning attachment coupled for rotational movement with the output drive shaft and having an axis of rotation; and
a liquid delivery system operable independently from the motor and having a reservoir, a valve, a valve actuator, a nozzle
coupled to the housing, and at least one fluid conduit, the reservoir being coupled to the housing and operable for storing
a pressurized fluid therein, the valve being at least partially housed in the housing and operable for selectively permitting
fluid communication between the reservoir and the nozzle in response to movement of the valve actuator and dispensing fluid
from the liquid delivery system, the nozzle being operable for directing the dispensed fluid obliquely relative to the axis
of rotation of the cleaning attachment and having at least one aperture being operable for dispersing the fluid dispensed
from the liquid delivery system; and
wherein the reservoir has a variable internal volume.
