A sponge cleaning device has a lid for enclosing and hiding a sponge when not in use. The sponge cleaning device has a bottom shelf that can be raised and lowered into a cleaning solution disposed in a base of the device. When the lid is closed, the bottom shelf lowers toward the base, causing a sponge resting on the bottom shelf to be lowered into the cleaning solution. When the lid is opened, the bottom shelf raised out of the cleaning solution and toward a top shelf. The top shelf can be movably disposed to compress the sponge when the sponge is on the bottom shelf and the lid is opened, thus squeezing out cleaning solution from the sponge. The top shelf can be movably disposed to permit the user to access the sponge and remove it from the bottom shelf for use.

A device for cleaning a beater bar of a vacuum cleaner includes a flexible body with an elongated rubber strip with blades attached that is so positioned as to be parallel to the beater bar when the device is disposed for cleaning the beater bar; blades penetrating the elongated opening under a vacuum for pulling, tearing and cutting hair and debris from the beater bar. The device is particularly useful for cleaning hair and debris off of beater bars in vacuum cleaners.

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.

The invention relates to a 3D printer (10) having a coater (30) and a coater-cleaning device (50). The coater (30) has a container (32), which defines an inner hollow space (34) for receiving particulate building material, and a discharge region (36) for discharging the particulate building material, said coater being movable into a cleaning position in which the coater is arranged above the coater-cleaning device (50). The coater-cleaning device (50) has a wiper element (52) for wiping the discharge region (36), said wiper element being formed from an absorbent material which is configured to receive a liquid cleaning agent inside the material.

A method for cleaning teeth of a lice comb, the method comprising the steps of: providing a cleaning pad (14); applying said teeth (12) into said cleaning pad (14); brushing hair while said teeth (12) are applied into said cleaning pad (14), for filtering lice and eggs by said lice comb teeth; and removing said cleaning pad from said comb, thereby removing lice and eggs filtered by said cleaning pad; wherein said cleaning pad comprises deformable material for gripping each of the comb's teeth around, thereby preventing from lice and eggs to pass through said cleaning pad.

A system and method for cleaning surfaces is disclosed. The system includes an elongated blade configured to remove at least one of dirt, dust, debris and film from a smooth surface. A drive system is provided for causing the blade to contact the entire smooth surface, thereby removing at least a portion of at least one of dirt, dust, debris, and film. A cleaning device automatically cleans the blade before and after the blade is cleaning the smooth surface. In one example, system is part of a heliostat system for use in a solar collection field as part of a concentrated solar power (CSP) plant.

A docking station includes a base and a cleaning member assembly. The cleaning member assembly includes at least one cleaning member, a first bracket, a second bracket, and a power source. Each of the at least one cleaning member is mounted on the first bracket and the second bracket. One of the first bracket and the second bracket is a fixed bracket, and the other is a movable bracket. The movable bracket is driven to reciprocate along a straight line, in order to drive each the cleaning member to swing relative to the first bracket around a central axis.

A vacuum hole for suction holding a processing target object through vacuum is formed on a stage surface of a vacuum suction holding stage, and a hole corresponding to the vacuum hole is formed on an elastic pad. A jig includes a first projecting portion configured to be insertable into the vacuum hole on the vacuum suction holding stage, a support portion configured to come into contact with the stage surface with the first projecting portion inserted in the vacuum hole, and a second projecting portion projecting toward an opposite side to the first projecting portion with respect to the support portion and configured to be insertable into the hole on the elastic pad.

A cleaning apparatus includes a scraper and a support member. The scraper is in contact with a surface of a recovery roller to clean out residuals from the surface. A base portion of the scraper is held between and a fixing plate and a supporting plate. In this case, a leading end of the scraper is in contact with the surface of the recovery roller while an edge of the supporting plate serving as a fulcrum. Also, a base length d of the scraper from the fulcrum to the base portion is selected to make uniform the contact pressure of the scraper.

The present invention relates to a substrate cleaning apparatus and a substrate cleaning method for cleaning a substrate, such as a semiconductor wafer, and more particularly to a substrate cleaning apparatus and a substrate cleaning method for cleaning a periphery of a substrate. A substrate cleaning apparatus (1) includes: a substrate holder (10) configured to hold and rotate a substrate (W); a pressing structure (22) having an internal space (R) and configured to press a cleaning tape (19) against a periphery of the substrate (W); a pressing-structure moving mechanism (30) configured to regulate a position of the pressing structure (22) in a radial direction of the substrate (W); and a pressure regulator (44) configured to regulate pressure in the internal space (R). The pressing structure (22) includes: a hollow support member (24) having an opening (25); and an elastic element (27) configured to support the cleaning tape (19). The elastic element (27) is arranged to close the opening (25).
