Change the filter dust bag regularly. If you do not replace the filter dust bag when it's full, the vacuum will become clogged. Once clogged, the vacuum can't clean because air will not be able to pass through the filter dust bag. Use the Oreck brand filter dust bag designed for your vacuum cleaner whenever you are making a replacement.
Remove excess debris such as lint, hair or string from the revolving brush at least once a month. Turn the vacuum over to reveal the revolving brush. Manually turn the brush and remove the debris by pulling it free from the brush. If applicable, use a pair of scissors to carefully cut any string or hair that is tightly entangled in the brush.
Wipe the outside of the vacuum cleaner with a soft damp cloth. Wipe down the entire surface area, including the handles and base.
Clean the attachments such as hoses and extenders. Wash the attachments in warm soapy water, rinse them and allow them time to dry completely before putting them back on the machine.
