A paint sprayer for sprayer a fluid includes a pump housing, an electrical housing having a motor and a switch, a handle coupled to the pump housing, a paint cup coupled to the handle, and a mechanical actuator coupled to the pump housing for operating the motor. The actuator has a first portion positioned in the vicinity of the exterior of the pump housing and a second portion that extends into the pump housing. The second portion is configured to engage the switch in the electrical housing to operate the motor. The handle is an elongated member having a top end and a bottom end, with a generally rectangular cross-section at the top end and a generally circular cross-section at the bottom end.

The method as claimed in claim 1, further comprising the step of rotating the inner tub in a reverse direction after the inner tub is rotated in the direction for a preset time period. 3. The method as claimed in claim 2, further including the step of either stopping the inner tub suddenly or rotating the inner tub in the reverse direction, whereby inertia of the laundry and the washing water caused by a change of rotation direction of the inner tub or a reverse direction rotation force forms a vortex which washes or rinses the laundry. 4. A method for controlling a washing machine, the washing machine comprising: an outer tub mounted in a washing machine body, for storage of washing water; an inner tub rotatably mounted in the outer tub and having a plurality of washing holes in a wall thereof for discharge of the washing water to the outer tub; a pulsator rotatably mounted as one unit with the inner tub; a motor directly coupled to the inner tub and the pulsator; and a tub cover mounted on a top of the outer tub for guiding the washing water to the inner tub when the washing water is circulated from the inner tub to the inner tub again through the outer tub by the rotation of the motor, wherein the inner tub is rotated at a first speed in a first or a second, reverse direction by the motor, the washing water penetrates through the laundry at a speed higher than a speed required to wash the laundry due to a centrifugal force generated by the rotation of the inner tub and circulates to the inner tub again through a space provided between the inner tub and the outer tub, and the laundry is dropped by an inertia caused by a rotation direction change of the inner tub when a washing cycle is complete. 5. A method for controlling a washing machine, comprising: (1) a laundry moving step comprising rotating an inner tub formed as a unit with a pulsator in one direction for moving laundry against a wall of the inner tub; (2) a washing water penetrating step comprising carrying out washing or rinsing as the washing water penetrates through the laundry due to the rotation of the inner tub; (3) a washing water pumping step comprising discharging the washing water passed through the laundry to an outer tub through washing holes formed in the inner tub thereafter moving the washing water upward; (4) a circulating step comprising circulating the pumped washing water to an inside of the inner tub using the cover as a guide; and (5) repeating the steps (1)_(4) by rotating the motor in a reverse direction. 6. The method as claimed in claim 5, further comprising the steps of conducting an agitating washing, and an agitating rinsing by rotating the inner tub at a speed lower than the first speed. 7. The method as claimed in claim 1, wherein the washing water is discharged into the outer tub via holes provided in the inner tub. 8. A method for controlling a washing machine having an inner tub configured to receive therein items to be washed and an outer tub in which the inner tub is rotatably mounted, the washing machine having at least a washing cycle, the method comprising: rotating the inner tub in a first direction at a first speed; discharging the washing water from the inner tub into the outer tub; and recirculating the washing water into the inner tub, wherein the first speed is sufficient to force washing water to penetrate through the items to be washed, to flow from the inner tub into the outer tub, and to recirculate through the outer tub back into the inner tub. 9. The method of claim 8, wherein the step of discharging the washing water from the inner tub into the outer tub comprises discharging the washing water from the inner tub to the outer tub via one or more holes provided in the inner tub. 10. The method of claim
