A cleaning apparatus includes an end cap assembly for use with an agitator. The end cap assembly includes a stationary end cap, a rotating end cap, and a fragmentor. The stationary end cap is secured to and stationary with respect to a housing of the cleaning apparatus. The rotating end cap is coupled to the agitator and rotates with the agitator relative to the housing. The stationary and rotating end caps define a gap extending radially inward therebetween. The fragmentor is disposed within the gap and is configured to break debris which enters the gap into smaller pieces. The fragmentor may be disposed on a surface of the stationary end cap facing towards the rotating end cap and/or on a surface of the rotating end cap facing towards the stationary end cap. The fragmentor may include a cutting blade and/or an abrasive surface.

A surface treatment apparatus may include a first agitator, a second agitator, and a drive system configured to cause the second agitator to rotate concurrently with the first agitator, the drive system including at least a first magnetic gear and a second magnetic gear.

An autonomous coverage robot includes a cleaning assembly having forward roller and rearward rollers counter-rotating with respect to each other. The rollers are arranged to substantially maintain a cross sectional area between the two rollers yet permitting collapsing therebetween as large debris is passed. Each roller includes a resilient elastomer outer tube and a partially air-occupied inner resilient core configured to bias the outer tube to rebound. The core includes a hub and resilient spokes extending between the inner surface of the outer tube and the hub. The spokes suspend the outer tube to float about the hub and transfer torque from the hub to the outer tube while allowing the outer tube to momentarily deform or move offset from the hub during impact with debris larger than the cross sectional area between the two rollers.

A surface cleaning apparatus includes a housing having a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. Various motor cooling arrangements are disclosed. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft floor surfaces.

A surface cleaning apparatus includes a housing including a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and for different cleaning modes, including wet cleaning, dry vacuum cleaning, and self-cleaning. A brushroll is provided on the base, along with various wipers, squeegees, and/or fluid dispensers.

Systems and methods for navigating an autonomous vacuum are disclosed. According to one method, the autonomous vacuum traverses a cleaning environment having a plurality of surfaces. As the autonomous vacuum is traversing the cleaning environment, sensors on the autonomous vacuum capture sensor data describing a first section of a surface on which the autonomous vacuum is currently traversing. Based on the received sensor data, the autonomous vacuum can determine that the first section is of a first surface type of a plurality of surface types. The autonomous vacuum can generate a user interface with a background displaying the determined first surface type to notify the user of where the autonomous vacuum is cleaning.

A floor cleaner including a vacuum source, a handle, and a base. The handle is pivotally coupled to the base, the handle pivotable between an upright storage position and an inclined operating position, the base movable over a surface to be cleaned. The base includes a suction inlet in fluid communication with the vacuum source, a brushroll chamber including a rear wall, a brushroll in the brushroll chamber, the brushroll rotatable about a brushroll axis, and a brushroll cover releaseably attached to the base, the brushroll cover removable to access the brushroll chamber and the brushroll, and the brushroll chamber rear wall is attached to and removable with the brushroll cover.

A cleaning machine may include: a first brush comprising a first brush shaft extending in a left-right direction and a first brush body held by the first brush shaft; a second brush comprising a second brush shaft extending in the left-right direction and a second brush body held on the second brush shaft; a brush supporting member supporting each of the first brush and the second brush such that the first brush and the second brush are rotatable; a body supporting the brush supporting member such that the brush supporting member is pivotable; and a pivot mechanism configured to pivot the brush supporting member with respect to the body. At least the first brush may move with respect to the body in an up-down direction when the brush supporting member pivots with respect to the body.

A surface cleaning device may include a nozzle, a dust cup, a suction motor configured to draw air into the nozzle and through the dust cup, and a first deodorizer coupled to the nozzle, the first deodorizer includes a deodorizing composition having a long chain fatty acid.

A cleaner head having a first support portion and a second support portion of a brush case rotatably supporting a brush drum, includes a base portion forming an end of the brush case, a bearing mounting portion protruding toward the brush chamber from the base portion to support a bearing coupled to one end portion of the brush drum and providing an insertion space into which an end portion of a driving housing is insertable, and a driving mounting portion arranged to be separated from the bearing mounting portion and supporting an end portion of the driving housing inserted into the insertion space.
