I have had the 3011L for several months, using it for general building construction cleanup as well as dust extraction. The vacuum is very good, works great as a dust extractor but does not have as much suction as my Karcher WD3. The WD3 is used for most of my general cleaning, rubble and etc. removal and the Makita 3011L is mostly reserved for dust extraction. If I were to buy a dust extractor again I would get a Festool CT 15.
