This is a powerful workhorse made for professionals. The dust bag catches most sawdust. You can attach a vacuum instead and catch even more. This unit is not a disposable homeowner tool, it is made to last and it can be repair. The most likely repair issue will be a need for new motor brushes, which is an easy maintenance item requiring no disassembly. I've used this for hours at a time, and it is definitely up to the challenge. This has a heavy duty electrical motor, so make sure that if you need an extension cord you use a heavy duty cord and one no longer than necessary. Longer and lighter cords cause premature wear on the motor.
