No, vacuum cleaners for ash removal were designed for a reason. Your residential vacuum was not made to clean up ash from the fireplace or the BBQ. Unfortunately, the parts of a regular vacuum can’t withstand heat, and you might end up ruining the machine. Even if the ash is cool, there might be hot coals hidden inside. Imagine those going through the hose of your residential vacuum. It’s definitely not going to end well. You shouldn’t use a home vacuum because ash can be very harmful to the motor. This is a machine that you spent money on and one you should use for a while. If you start vacuuming ash, the chances are it will soon need repairs (or you needing to buy a new machine).
