Instructions
Turn off the PS3.
Disconnect the power cable and HDMI cables from the PS3 console to reduce the chance of electrical damage.
Grasp the dirt compartment of your low-powered vacuum cleaner. Clear the compartment and wipe the dust from the vacuum cleaner's nozzle.
Turn the PS3 so that the vents face you. Hold the vacuum cleaner so that its nozzle rests just beyond the right side of the vents.
Vacuum the vents.
Wipe dust off other areas of the PS3 with a clean, soft cloth.
