Robust, efficient vacuum! Used for ash (hearth and pellet), suction is effective and lopération is dust around. In less than a minute I perform maintenance on my woods devices and I empty the vacuum cleaner every two or three days. All ranks on the body of the device, thread, accessories and flexible. It is fairly compact size and has a washable filter with water. While it is more expensive than many others but it is effective and appears to hold out. I use it exclusively for the ashes and it really is perfect. It makes a little noise but not too bad. Would recommend no problem!
