Robotic surface-cleaning assemblies include a base configured to be operatively coupled to a robotic arm; a supply of cleaning fabric supported relative to the base; an applicator supported relative to the base, wherein the applicator is configured to support a portion of cleaning fabric from the supply of cleaning fabric and operatively and selectively position the portion into engagement with a surface to be cleaned; and a source of cleaning fluid supported relative to the base, wherein the source of cleaning fluid is configured to operatively and selectively (i) deliver cleaning fluid directly to the portion of cleaning fabric supported by the applicator and/or (ii) deliver cleaning fluid directly to the surface to be cleaned. Methods of cleaning a surface with a robotic surface-cleaning assembly also are disclosed.

A cleaning device is provided that includes a housing, a cleaning head, a flexible pouch, a cleaning element, and a nozzle. The housing defines an internal cavity having a power source in selective electrical communication with a pump. The flexible pouch is removably stored in the housing and includes a cleaning fluid therein. The pouch forms a fluid and air tight connection with an inlet of the pump. The cleaning element is connected to the cleaning head and has a first opening. The nozzle is in fluid communication with an outlet of the pump. The nozzle is positioned on the cleaning head so as to release the cleaning fluid from the flexible pouch through the first opening onto a surface being cleaned.

A faucet cleaner. The faucet cleaner includes a supply bottle having a base, a sidewall extending from the base, and a neck. The neck includes a top end having a rim forming an opening into the supply bottle. A delivery cup is secured to the neck of the supply bottle. The delivery cup includes a base and a sidewall extending from the base. A channel runs from inside the supply bottle through the opening formed by the rim of the neck, through the base of the pump mechanism and into delivery cup so that the top end is disposed in the delivery cup. A plurality of bristles are secured to the base of the delivery cup and disposed within the delivery cup.

A substrate cleaning device (31) includes a roll cleaning member (61) and a rotation holding portion (100). The rotation holding portion (100) includes a non-contact sealing portion (140) that is disposed between a bearing portion (130) and the roll cleaning member (61) to seal a gap between a shaft portion (110) and a housing portion (120). The non-contact sealing portion (140) includes a rotating portion (150) that is attached to the shaft portion (110) and has a plurality of protrusion portions (151) formed on a peripheral surface (150a) of the rotating portion (150) at intervals in an axial direction, and a fixed portion (160) that is attached to the housing portion (120), surrounds the plurality of protrusion portions (151), and has a gas supply hole (161) formed in an inner peripheral surface (160a) of the fixed portion (160) surrounding the plurality of protrusion portions (151), the gas supply hole (161) supplying a compressed gas (200) from a position inward of the protrusion portions (151) in the axial direction, which are disposed at both end portions in the axial direction, among the plurality of protrusion portions (151).

A car wash system that may be stored or installed in a residential or commercial building, such as a garage in a home or car dealership, respectively. The system may include wash units that are attachable to a guide such as a track attachable to a ceiling or wall of the garage, a raised rail or inset groove on a floor of the garage, or both. The guide may be arranged inside of the garage and may extend outside of the garage temporarily or permanently. The system may have a closed configuration for storage inside the garage and an open configuration for washing the vehicle either inside or outside of the garage. Transitions from the open to closed configurations and vice versa may be automatic, such as controlled by a control panel or handheld device.

Aspects and techniques of the present disclosure relate to a cleaning substrate with liquid-filled microcapsules embedded therein. The cleaning substrate may include cleaning swabs, tapes, or textiles that can be used to provide enhanced cleaning of optical fiber end faces. Cleaning is achieved by bringing the liquid-filled microcapsules into contact with a surface of application, such as an end face of an optical fiber connector. When the cleaning substrate is rubbed in contact with the surface of application, liquid burst from the liquid-filled microcapsules of the cleaning substrate to remove foreign matter or contamination, such as oil and dust, from the surface of application.
