1 Hour VACUUM CLEANER Black Screen Audio Only HD

1 Hour vacuum cleaner sound effect on loop — 1 hour black screen — baby calming.

THIS VIDEO IS A STILL IMAGE — black screen with a small line-art icon in the middle. There is NO ANIMATED VIDEO. Pure audio for hearing-test checks, alarm-replacement loops, study background, sleep timers, or just letting the sound run while you do something else.
