Abstract
A docking station for a vacuum cleaner may include a receptacle configured to engage at least a portion of the vacuum cleaner such that, in response to engaging the receptacle, a vacuum cleaner flow path extending within the vacuum cleaner is transitioned from a cleaning flow path to an evacuation flow path, a suction motor of the vacuum cleaner being configured to urge air along the vacuum cleaner flow path and a docking station dust cup configured to receive debris from a vacuum cleaner dust cup of the vacuum cleaner.
Claims20
A vacuum cleaner having a vacuum longitudinal axis extending lengthwise, the vacuum cleaner comprising:
- an air inlet;
- an air outlet;
- an airflow pathway extending between the air inlet and the air outlet;
- a motor operable to move air along the airflow pathway from the air inlet downstream toward the air outlet;
- a debris separator arranged between the air inlet and the motor along the vacuum longitudinal axis, the debris separator comprising:
- a debris collection chamber having a chamber longitudinal axis extending lengthwise parallel to the vacuum longitudinal axis;
- a clean air chamber arranged downstream of and lateral to the debris collection chamber;
- and
- an elongate filter arranged parallel to the chamber longitudinal axis, the elongate filter extending coaxially with a longitudinal axis of the motor, the elongate filter laterally separating the debris collection chamber and the clean air chamber, wherein the elongate filter comprises an arcuate cross section including a first side facing the debris collection chamber and a second side downstream of the first side facing the clean air chamber, wherein the air flows from the first side of the elongate filter to the second side of the elongate filter along the airflow pathway to catch at least some of debris in the elongate filter;
- a wiper configured to move relative to the elongate filter to dislodge debris from the elongate filter;
- and
- a battery.

A vacuum cleaner comprising:
- a vacuum longitudinal axis extending lengthwise;
- a debris separator arranged along the vacuum longitudinal axis, the debris separator comprising:
- an air inlet;
- a filter;
- a dust cup;
- and
- a clean air chamber downstream of the dust cup, the filter laterally separating the dust cup and the clean air chamber, wherein the filter comprises an arcuate cross section including a debris collection side and a clean side downstream of the debris collection side, the debris collection side of the filter facing the dust cup and the clean side of the filter facing the clean air chamber;
- a motor configured to urge air along an airflow pathway through the air inlet and the debris separator, wherein the airflow pathway flows from the debris collection side of the filter to the clean side of the filter such that at least some of debris is caught by the debris collection side, the motor positioned coaxially with a longitudinal axis of the filter along the vacuum longitudinal axis;
- and
- a wiper configured to dislodge debris from the debris collection side of the filter.

A vacuum cleaner for removing debris from a surface, the vacuum cleaner comprising:
- an airflow within the vacuum cleaner from a dirty air inlet to a clean air outlet;
- a front end proximate the dirty air inlet;
- a rear end opposite the front end;
- a surface cleaning head configured to removably couple to the front end to provide fluid communication between the surface cleaning head and the dirty air inlet;
- an axially extending air treatment chamber partitioned into a debris collection side and a clean air side by a filtration assembly arranged parallel to a longitudinal axis of the air treatment chamber, the filtration assembly comprising a particulate filter and a mesh filter, the filtration assembly arranged downstream of and lateral to the debris collection side and upstream of and lateral to the clean air side, the filtration assembly axially extending along the air treatment chamber and including an arcuate cross section;
- a suction motor operable to move air along the airflow, the particulate filter and the mesh filter extending coaxially with a longitudinal axis of the motor;
- a wiper linearly movable along the filtration assembly to dislodge debris;
- and
- an axially extending handle proximate the rear end.
