the vacuums go back to the mid 1800s but they became electric in 1910 for the vacuum cleaner , 1931 for the electric guitar.
Use an antique hand pumped vacuum cleaner (they existed before the electric ones).
James Murray Spangler invented the first motorized, portable vacuum cleaner. Spangler was a janitor in Ohio and used an electric fan, a box, and one of his wife's pillowcases.

Although it is called a vacuum cleaner, it does not actually create a vacuum. Inside the cleaner there is an electric motor which drives a fan blade. This fan blows air out of the vacuum cleaner and this causes air to be drawn in to the cleaner at the other end. Thus the cleaner works by creating an air flow, not a vacuum.

In general, yes, a good working vacuum cleaner can pick up small stones if the stones are small enough.
Not as quick, but then it frees time up for the would be human cleaner. Quality is not a big difference.
That depends on the distance to the vacuum cleaner. The closer, the louder.

Most vacuums become louder hte more they are used so there really is no "quiet" vacuum cleaner.
