Background and Identification
If you own a Dyson vacuum cleaner and are unsure of what model you have, look on the lower front of the device. The model number should be silk-screened on the front-left of the front bezel that covers the brush. The model pictured is the Complete variant of the Dyson DC 14. There are other models of the DC 14 that may vary in color and attachments included--this guide will work for those models.
The Dyson DC14 was released in 2004 as a revision of the original upright DC7 vacuum. Utilizing Dyson's Root 8 Cyclone technology, this vacuum delivers constant suction, improving cleaning performance.
