The only two settings on this Dyson vacuum are “High Suction” and “Max Suction” and do words even have meaning anymore?
Replying to @andrechemist
Since pressure can't be negative, I'd assume "Max Suction" would be about one atmosphere. ;) (By that definition there's no significant difference in "suction" between HV and UHV pumps. Yes technically pressure can be negative, but not in a Dyson. See Xylem tubes in high trees.)
