The vacuum level is determined by the pressure differential between the evacuated volume and the surrounding atmosphere. Several units of measure can be used. Most refer to the height of a column of mercury â usually inches of mercury (in.-Hg) or millimeters of mercury (mm-Hg).
The maximum amp draw, (the number of amps the vacuum cleaner uses when running) allowed for any appliance that plugs into a standard household outlet is 12. Therefore, if you see amperage ratings above 12, read the fine print, as they are not true amperage specifications but some other manufacturer developed performance rating designed to create the impression of a more powerful vacuum cleaner.
