Abstract
A liquid-permeable brush roll may include a main body having a radial surface, a cavity having an open end, a stopper removably coupled to the main body at the open end of the cavity, and one or more weep holes defined in the radial surface of the main body and fluidly coupled to the cavity. The cavity extends within the main body and is configured to store a cleaning fluid therein.
Claims16
A liquid-permeable brush roll comprising:
- a main body having a radial surface;
- a cavity having an open end, the cavity extending within the main body and being configured to store a cleaning fluid therein;
- a stopper removably coupled to the main body at the open end of the cavity;
- one or more weep holes defined in the radial surface of the main body and fluidly coupled to the cavity;
- and
- a multi-layer outer sheath configured to slidably engage the radial surface of the main body, the multi-layer outer sheath including:
- a face layer that includes a hydrophobic material;
- an airlaid first absorbent layer having a first airlaid density;
- and
- an airlaid second absorbent layer having a second airlaid density, the second airlaid density being higher than the first airlaid density, the airlaid first absorbent layer being disposed between the face layer and the airlaid second absorbent layer.

A cleaner comprising:
- a chassis;
- and
- a liquid-permeable brush roll rotatable relative to the chassis, the liquid-permeable brush roll including:
- a main body having a radial surface;
- a cavity having an open end, the cavity extending within the main body and being configured to store a cleaning fluid therein;
- a stopper removably coupled to the main body at the open end of the cavity;
- one or more weep holes defined in the radial surface of the main body and fluidly coupled to the cavity;
- and
- a multi-layer outer sheath configured to slidably engage the radial surface of the main body, the multi-layer outer sheath including:
- a face layer, the face layer including a hydrophobic material;
- a first absorbent layer, the first absorbent layer including a first airlaid material having a first airlaid density;
- and
- a second absorbent layer, the second absorbent layer including a second airlaid material having a second airlaid density, the second airlaid density being higher than the first airlaid density, the first absorbent layer being disposed between the face layer and the second absorbent layer, the face layer, the first absorbent layer, and the second absorbent layer each being a different layer.

A robotic cleaner comprising:
- a chassis;
- a plurality of drive wheels configured to be independently driven;
- one or more sensors;
- a liquid-permeable brush roll rotatable relative to the chassis, the liquid-permeable brush roll including:
- a main body having a radial surface;
- a cavity having an open end, the cavity extending within the main body and being configured to store a cleaning fluid therein;
- a stopper removably coupled to the main body at the open end of the cavity;
- one or more weep holes defined in the radial surface of the main body and fluidly coupled to the cavity;
- and
- a multi-layer outer sheath configured to slidably engage the radial surface of the main body, the multi-layer outer sheath including:
- a face layer that includes a hydrophobic material;
- an airlaid first absorbent layer having a first airlaid density;
- and
- an airlaid second absorbent layer having a second airlaid density, the second airlaid density being higher than the first airlaid density, the airlaid first absorbent layer being disposed between the face layer and the airlaid second absorbent layer;
- and
- a brush roll motor configured to rotate the liquid-permeable brush roll, wherein the brush roll motor is configured to cause the liquid-permeable brush roll to rotate according to a mixing mode, the mixing mode being configured to mix the cleaning fluid within the cavity.
