You’ll need to pull these out by hand, although you can reduce the chance of them developing by avoiding overfilling the bin..
Shark’s bagless upright vacuums are always easy to empty.This is important, as their dust cups are typically smaller than uprights from other brands – particularly bagged models..

Unlike many vacuums, Shark Lift-Away vacuums have two lids for emptying the different sections of the cup.Many owners don’t realise they need to use both lids to fully empty the vacuum..Check your manual for your machine’s specific instructions, but here’s the basic process for emptying a Shark Lift-Away:.

Unplug the vacuum (always unplug a corded vacuum before performing any maintenance)..Remove the dust cup from the vacuum by pressing the button at the top of the main body and tilting the cup towards you..

Hold the dust cup over a bin and press the bottom release tab to allow the contents to fall into the bin.
Give it a quick shake or tap to dislodge any stuck debris.. Now use the top release tab to open the top lid while holding the cup over the bin.There’s also a chance that the ash will go right through the machine and blow out its air vents into the air you’re breathing, making vacuuming ash not only a futile cleaning attempt but a potential health threat too.. 5.
Construction Dust.What happens to your vacuum cleaner when it sucks up fireplace ash can also occur when other types of fine dust, like construction dust and sawdust from home improvements, are vacuumed.. Construction dust and sawdust also clog your vacuum cleaner’s filter, overwork its motor, and can escape through the machine’s air vents.
need a commercial vacuum.with a filter that can handle this type of dust.. 6.
