When I vacuum gritty stuff like grains, cats litter or remnants of her food that has dried (she’s a messy eater!!) I like the noise it makes as it get sucked up.
Another vacuum one, every couple months I get old tweezers and a thin wire to pick at the dust that’s in the vacuum head, the wheels, brushes, hard to reach spots. Extra satisfying if there’s a substantial little dust bunny hiding in the crevices.
After washing and drying the cat's bedding, her fur ends up as little balls stuck on the sheets. I just like picking them off.
