Having to work at the same time that I occupy the house I was looking for a decent vacuum cleaner to suck the dust plasters which are very thin and volatile, and often clog the passage of vacuum filters (domestic vacuum cleaner there was not survived)
I use a manual bilge sanding (Abranet) I connected the Karcher vacuum to limit the dispersion of dust and this is the top.
I have almost no dust flying. Suction is very good.
For protection reasons, I still add an extra filter around the motor filter on the seller's advice. But I want to say even without any dust remains confined in the bag supplied. The motor filter nickel remains after ten hours of use to eat plaster.
By not overheating problem, I'm running for over an hour quietly grind my wall and ca roll!
In short, for the price, I regret not having made this purchase early!
Only downside, the hose is a little short to me.
Now, over time, I would see how grown old vacuum cleaner.
