Dyson Hot & Cool AM09 2015 Used item, so please understand. Warm air, cool air, oscillation, and power level have been confirmed to be working. Please check the condition in the photos. Both the main unit and the remote control have stickiness due to plastic degradation. The operation is perfectly normal, but please refrain from purchasing if you are concerned about the stickiness. I wiped down the entire unit, but there are areas where the stickiness and dust could not be removed. If you like stylish machines and don't mind the stickiness once the room is warm or cool, please consider it. The remote control works without any problems. No smokers, no pets. * Can be used throughout the year * Heats the room quickly and evenly in winter, and can be used as a fan in summer * The only fan heater equipped with Jet Focus Control * Focus mode delivers powerful airflow over a long distance, and wide mode draws in surrounding air to deliver airflow over a wide area. * Patented Air Multiplier technology! * Patented Air Multiplier technology delivers smooth and powerful airflow. Since there are no blades, it can be used safely in homes with pets and babies. I found it very useful because it quickly cools and warms the entire room, but I am selling it because I have used it less frequently.
