Cleaning apparatus with sound dampening feature

A cleaning apparatus, comprising:

• a suction assembly housing including a sidewall and a floor that define a receiving space, wherein the floor defines bypass apertures in the receiving space;
• a base plate defining an air outlet downstream of the bypass apertures;
• a suction source disposed at least partially in the receiving space, wherein the suction source includes an impeller cover defining at least one impeller outlet in fluid communication with a guide passage that is defined between the impeller cover, the sidewall, and the floor;
• and
• a sound dampening funnel positioned around the impeller cover and extending from proximate the at least one impeller outlet to the floor in the guide passage, wherein the sound dampening funnel extends at an acute angle from the sidewall and over a portion of the bypass apertures to reduce an open area of the bypass apertures through which air is configured to flow towards the air outlet, and wherein the air directed by the suction source through the guide passage is configured to interact with the sound dampening funnel as the air is guided toward the bypass apertures to reduce noise generated by said cleaning apparatus.

A cleaning apparatus, comprising:

• a base enclosure defining a suction port;
• a suction assembly housing including a sidewall, a floor, an intake opening, and bypass apertures, wherein the suction assembly housing includes a motor housing and an impeller housing;
• a base plate defining an air outlet, wherein an inlet passage is defined between the suction port and the intake opening, and further wherein an outlet passage is defined between the bypass apertures and the air outlet;
• a suction source operably coupled with the suction assembly housing, wherein the suction source is configured to direct air through the suction port, the inlet passage, the suction source, and the outlet passage, the suction source including:
• an impeller assembly disposed in the impeller housing, the impeller assembly having an impeller cover defining an impeller inlet and at least one impeller outlet;
• and
• a motor disposed in the motor housing and configured to drive the impeller assembly, wherein a guide passage is defined between the impeller cover, the motor housing, and the floor;
• and
• a sound dampening funnel disposed on the floor in the guide passage, wherein the sound dampening funnel extends at an acute angle from the sidewall proximate to the at least one impeller outlet, toward the impeller cover, and to the floor to extend over the bypass apertures and reduce an airflow portion of the bypass apertures through which the air is directed by the suction source from the guide passage to the outlet passage.
