Compact and bagless, a Eureka Optima vacuum cleaner, which is part of the manufacturer's 430 series, is ideal for use on your home's carpeting and bare floors. The appliance is also easy to maneuver, weighing in at just 12 pounds. If you have pets, the Optima comes in the Pet Lover Oh! version, which is designed to remove pet hair and features a charcoal filter for removing odors and allergens. When you notice that your vacuum cleaner isn't performing as well as it usually does, it may be time to clean its filter. It may even be necessary to replace the filter after several months of use.
Turn the vacuum cleaner's power switch into the "Off" position and unplug the appliance from any power source.
To check the filter to see if it needs to be cleaned. Push the "release cup" button and remove the dust cup from the appliance. Twist the cup's lid, which is attached to the filter, in a counterclockwise direction to open. Lift the dust cup lid, along with the attached filter, out of the vacuum.
Push the filter latch to remove the filter from the dust cup lid. Shake the filter to remove any dust and debris that is attached to it while standing over a garbage can. You may need to pull any larger pieces off with your fingers to dislodge them from the filter.
Snap the filter back into the dust cup lid, slip it into the appliance and twist the lid in a clockwise direction to lock it into place.
