One more tip

Always unplug and allow the appliance to cool first. Dyson Supersonic guidance says to clean its filter mesh with a dry brush, without water or chemicals. Certain Shark SpeedStyle models permit washing a removable filter. Never swap procedures between models. Stop using an appliance with a damaged cord, burning smell or persistent overheating and contact the manufacturer.
