Troubleshoot a problem with a Dyson vacuum by first identifying the main issue, such as poor suction or loss of power, and checking the relevant components for blockages or damage. Alternately, the Dyson website includes detailed support sections for diagnosing and resolving various issues with each of its models, as of 2015.
To troubleshoot an issue with a Dyson vacuum on your own, first determine the exact nature of the problem. For example, if the vacuum fails to pick up items on the floor, it may be a suction issue, while the vacuum depositing new debris onto the floor may be a sign of a seal issue. Test the vacuum in different environments and with different outlets to confirm the issue, then unplug the unit and examine the necessary components. Many issues likely result from common situations such as a clog in the suction system, a dirty filter or a damaged seal on one of the connector points.
