1. A vacuum cleaner comprising:
- a housing having a sidewall and a top wall defining a cyclonic airflow chamber for separating contaminants from a dirt-containing airstream, the housing further comprising an inlet and an outlet in fluid communication with the cyclonic airflow chamber, and, optionally, a dirt cup with a sidewall;
a nozzle housing including a main suction opening, the main suction opening being fluidly connected with the housing inlet;
an airstream suction source fluidly connected to the main suction opening and to the cyclonic airflow chamber for transporting dirt-containing air from the main suction opening to the cyclonic airflow chamber, wherein the suction source is adapted to establish and maintain the dirt-containing airstream from the main suction opening to the housing inlet; and
a fine contaminant separation member formed in at least one of the walls of the cyclonic airflow chamber and the sidewall of the dirt cup and comprising a plurality of apertures for separating fine contaminants from the dirt-containing airstream as the dirt-containing airstream flows by the fine contaminant separation member.

Abstract
A cyclone separator assembly comprises a cyclone separator that removes large particles of dirt from a working airstream as it flows through the cyclone separator, and the separated large particles of dirt are deposited into a dirt cup. The cyclone separator assembly further includes a fine particle separation member comprising a plurality of apertures for separating fine particles of dirt from air in the cyclone separator or the dirt cup.

27. A particle separator comprising:
-
a housing having a sidewall and a top wall defining a cyclonic airflow chamber for separating contaminants from a dirt-containing airstream, the housing further comprising an inlet and an outlet in fluid communication with the cyclonic airflow chamber, and a dirt cup including a sidewall beneath the cyclone airflow chamber and in communication therewith to receive dirt particles separated from the dirt-containing stream in the cyclonic airflow chamber; and
at least one particle collector formed adjacent to at least one of the walls of the cyclonic airflow chamber and the sidewall of the dirt cup and connected to the at least one of the cyclonic airflow chamber and dirt cup through a fine contaminant separation member having a plurality of apertures for separating fine contaminants from air in the at least one of the cyclonic airflow chamber and the dirt cup. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A vacuum cleaner comprising:
-
a cyclone separator assembly comprising;
a frustoconical separator with inlet at an upper end and an outlet at a lower end and defining a cyclonic airflow chamber for separating contaminants from a dirt-containing airstream; and
a dirt cup with a sidewall that extends above the lower end of the frustoconical separator;
a nozzle housing including a main suction opening fluidly connected with the inlet of the frustoconical separator; and
an airstream suction source fluidly connected to the main suction opening and to the cyclonic airflow chamber for transporting dirt-containing air from the main suction opening to the cyclonic airflow chamber, wherein the suction source is adapted to establish and maintain the dirt-containing airstream from the main suction opening to the inlet of the frustoconical separator;
wherein a portion of the airstream exiting the frustoconical separator exits through the lower end and enters the dirt cup to create a second rotational airstream in the dirt cup to separate lighter debris contained within the dirt cup and prevent re-entry of the lighter debris into the frustoconical separator. - View Dependent Claims (41)
