Dyson vacuums are based on the theory that traditional vacuum cleaners lose suction as the dust bag or container becomes full with dirt and debris. Dyson vacuums therefore suction up air and spin it in a cyclonic action to separate dirt and debris from the air and do not use a dirt bag. The vacuums can be used to clean carpets, upholstery, stairs and other surface in a traditional manner. While your Dyson vacuum should function well with typical care and maintenance, if the unit overheats, it is most likely due to the built-in thermal cut out feature. Most often, the issue can be resolved by removing any blockages or cleaning the filter.
Turn off and unplug the Dyson vacuum. Allow the vacuum to sit for at least one hour to cool down completely.
Push down on the release lever and pull out the clear bin from the front of the vacuum. Lift up on the filter release and pull the filter from the top of the compartment. Place the filter in a bowl of cold water and allow to soak for 5 minutes. Rinse the filter under cold water and squeeze to remove extra dirt. Set the filter in a warm, dry place for 12 hours. Once dry, replace the filter in the cyclone compartment and close the compartment on the vacuum.
Examine the vacuum hose and nozzles for possible obstructions that may have caused the vacuum to overheat. Remove any potential blockages and wipe clean with a damp cloth.
Restore power and resume cleaning.
Contact Dyson if the thermal cut out happens again after performing the above steps.
