Cleaning systems configured to pick up pet hair

A hair cleaning system comprising:

• an outer housing;
• a basin pivotably coupled to the outer housing, wherein the basin is configured to hold a first hair inside the outer housing, and the basin comprises a first convex outer surface configured to pick up a second hair;
• a second surface pivotably coupled to the outer housing and configured to contact at least a first portion of the first convex outer surface as the first convex outer surface rotates relative to the second surface to remove the second hair from the first convex outer surface such that the second hair enters the basin;
• and
• a first pivot joint that pivotably couples a first leftward side of the outer housing to a second leftward side of the basin, wherein the first pivot joint comprises a first axis of rotation,
• wherein the first leftward side of the outer housing comprises a first wall that protrudes inward in a first direction and a second wall that protrudes inward in a second direction, wherein the first direction and the second direction are within 20 degrees of parallel to the first axis of rotation,
• the second leftward side of the basin comprises a third wall and a fourth wall that protrude outward toward the first leftward side of the outer housing, and
• the first wall is configured block a first rotation of the third wall about the first axis and the second wall is configured to block a second rotation of the fourth wall about the first axis such that the first wall and the second wall limit a maximum rotation of the basin relative to the outer housing to less than 140 degrees.

A hair cleaning system comprising:

• an outer housing;
• a basin pivotably coupled to the outer housing, wherein the basin is configured to hold a first hair inside the outer housing, and the basin comprises a first convex outer surface configured to at least partially protrude from a downward-facing side of the outer housing to pick up a second hair;
• a first concave surface pivotably coupled to the outer housing and configured to contact at least a first portion of the first convex outer surface as the first convex outer surface rotates relative to the first concave surface to remove the second hair from the first convex outer surface such that the second hair enters the basin;
• a first pivot joint that pivotably couples a first leftward portion of the outer housing to a second leftward portion of the basin, wherein the first pivot joint comprises a first axis of rotation;
• a first wall coupled to the outer housing and configured to limit a maximum rotation of the basin relative to the outer housing by blocking travel of a second wall of the basin;
• and
• a first protrusion, a second protrusion, a third protrusion, and a fourth protrusion that are spaced apart along an outer perimeter of the basin such that a cross section oriented perpendicular to the first axis comprises portions of the first, second, third, and fourth protrusions, wherein the first, second, third, and fourth protrusions protrude radially outward relative to the first axis and are configured to provide traction to help rotate the basin relative to the outer housing,
• wherein the second leftward portion of the basin comprises a third wall that protrudes in a first direction and a fourth wall that protrudes in a second direction, the first direction and the second direction are toward the first leftward portion of the outer housing and within 20 degrees of parallel to the first axis, and the third wall and the fourth wall secure a base of the first protrusion such that the base rotates with the basin.

• a hoop having the first, second, third, and fourth protrusions,
• wherein the second leftward portion of the basin comprises a third wall that protrudes in a first direction and a fourth wall that protrudes in a second direction, the first direction and the second direction are toward the first leftward portion of the outer housing and within 20 degrees of parallel to the first axis, and the third wall and the fourth wall secure the hoop such that the hoop rotates with the basin.
