Abstract
A mobile cleaner includes a body and a sweep module. The body has an installation space within the body and an insertion opening exposed to the underside of the body. The sweep module is detachably assembled to the installation space through the insertion hole. The sweep module includes a dust housing and an agitator. The dust housing includes a collection space for collecting the foreign material from the surface and a storage space where the foreign material is stored. The agitator is rotatably assembled to the dust housing and is configured to direct the foreign material from the surface to the collection space.
Claims19
A mobile cleaner, comprising:
- a body having an outer surface, a shape of the outer surface when viewed from a top of the body being at least a part of a circle, the body being configured to move on a surface;
- a sweep module positioned on a lower portion of the body to collect foreign material from the surface, the sweep module being vertically overlapped and covered by the body when viewed from the top of the body;
- a pair of spin mops rotatably coupled to the body, the pair of spin mops being configured to be in contact with the surface and to move the body on the surface;
- a first caster, and
- a second caster,
- wherein the sweep module comprises:
- an agitator configured to rotate and collect the foreign material from the surface;
- a dust housing including a storage space where the foreign material collected by the agitator are stored, and
- a fixed partition wall disposed inside the dust housing, wherein the fixed partition wall is tangent to a circular path of the agitator;
- wherein, with reference to a direction of movement of the body, the storage space is disposed at a front side of the agitator,
- wherein the storage space is positioned on a front side of the body relative to a center of the body,
- wherein the agitator has a width greater than a width of the storage space,
- wherein a width of a front end of the storage space is smaller than a width of a rear end of the storage space,
- wherein the first caster and the second caster are disposed laterally outside of the storage space,
- wherein the storage space is positioned at the front side of the body relative to the pair of spin mops,
- wherein the agitator is positioned between the pair of spin mops and the storage space,
- wherein a distance between the first caster and the second caster is greater than a distance between rotation axes of the pair of spin mops,
- wherein the first caster and the second caster are installed in the sweep module, and
- wherein the sweep module is configured to be detachably coupled to the body through an insertion hole.

A mobile cleaner, comprising:
- a body configured to move on a surface, the body having a substantially circular configuration when viewed from a top of the body;
- a pair of spin mops coupled on the body, the pair of spin mops being configured to contact the surface and rotate, wherein the rotation of the spin mops is configured to move the body on the surface;
- a sweep module coupled to the body, the sweep module being configured to collect foreign material from the surface as the body moves on the surface, the sweep module including a storage space, and an agitator configured to rotate and direct the foreign material on the surface into the storage space;
- a first caster disposed at a first end of the storage space;
- and
- a second caster disposed at a second end of the storage space,
- wherein the first caster and the second caster are disposed laterally outside of the storage space,
- wherein a rotation axis of each spin mop of the pair of spin mops is offset from a center of the body, and when viewed from the top of the body, a first portion of each spin mop of the pair of spin mops is covered by the body such that a ratio of an area of the first portion to a total area of each spin mop is 85% to 95%,
- wherein an imaginary line is defined as a line connecting the rotation axis of each spin mop of the pair of spin mops,
- wherein the body includes a central longitudinal line passing through the center of the body and perpendicular to the imaginary line,
- wherein a circular path of at least one spin mop of the pair of spin mops is tangent to the central longitudinal line,
- wherein the sweep module is covered by the body when viewed from the top of the body, wherein, with reference to a direction of movement of the body, the storage space is disposed in front of the agitator,
- wherein the storage space is positioned on a front side of the body relative to the center of the body,
- wherein the agitator has a width greater than a width of the storage space,
- wherein a width of a front end of the storage space is smaller than a width of a rear end of the storage space,
- wherein the storage space is positioned at the front side of the body relative to the pair of spin mops,
- wherein the agitator is positioned between the pair of spin mops and the storage space,
- wherein a distance between the first caster and the second caster is greater than a distance between rotation axes of the pair of spin mops,
- wherein the first caster and the second caster are installed in the sweep module, and
- wherein the sweep module is configured to be detachably coupled to the body through an insertion hole.
