Abstract: A mopping device includes a mopping portion, a fluid release device for releasing fluid to at least one of a surface to be mopped and the mopping portion, a handle configured to be gripped by a user to control the mopping portion, and a reservoir for storing fluid. The reservoir can include an expandable bladder. The reservoir also can be configured such that air need not be evacuated from the reservoir during filling of the reservoir. The mopping device also can be part of a mopping system, in which a refill reservoir is provided to refill the reservoir of the mopping device.

Abstract: A scale and cover comprises an electronic scale comprising a scale tray and a user control and a first alignment mechanism. A cover for removably receives the electronic scale where the cover defines an aperture communicating the exterior of the cover with the electronic scale. The cover comprises a second alignment mechanism that engages the first alignment mechanism. A tray comprises a leg that is inserted through the aperture and is supported by the scale tray.

Abstract: A receptacle includes a body configured to receive a liner and a cinch disposed on the body. The cinch includes a projection disposed outward of the body and configured such that at least a portion of the liner can be disposed between the projection and the body. The cinch further includes a slot having an open end and a closed end, wherein the slot is disposed substantially adjacent the projection and configured such that at least a portion of the liner can be disposed and retained within the slot.

Abstract: The liquid dispenser comprises a ratchet assembly, a rotor assembly, a reservoir assembly, and a drive mechanism. The reservoir assembly includes a reservoir and a reservoir tube; and the rotor assembly includes a drive gear and at least one compression element. The ratchet assembly includes a pawl configured to engage the drive gear when the drive mechanism is actuated. Optionally, the liquid dispenser includes a venting assembly and/or a dose control assembly. The venting assembly automatically vents the reservoir when the reservoir is mounted in the liquid dispenser. The dose control assembly allows the user to control the distance the drive mechanism may be actuated and thereby control the amount of liquid that is dispensed. The liquid dispenser of the invention provides accurate control over the amount of liquid that is dispensed as well as ease in replacing the reservoir.

Abstract: A drive provides rotational movement and linear movement to an output. A first gear is operatively connected to the output, such as a roller. A drive assembly comprises a first cam surface, a second cam surface and a second gear. The first cam surface engages a first follower where the first follower is operatively connected to the output such that linear movement of the first cam follower results in linear movement of the output. The second cam surface engages a stationary follower. The second gear engages the first gear. The drive assembly rotates over a range of motion such that for a first portion of the range of motion the drive assembly causes the rotational and linear movement of the output and rotation of the drive assembly for a second portion of the range of motion causes only the rotational movement of the output.

Abstract: A mop wringer comprises a housing supporting a first roller and a second roller. The first roller is supported by the housing in a first position where the first roller is spaced from the second roller a first distance and in a second position where the first roller is spaced from the second roller a second distance. The second roller is supported on an arm where the arm moves relative to the housing to move the second roller toward and away from the first roller between a third position and a fourth position. A drive mechanism moves the arm between the third position and the fourth position and rotates the roller in the fourth position.

Abstract: A mop comprises a handle and a first frame member comprising a first side and a second side. The handle is connected to the first side at a translating pivot such that the handle may translate and pivot relative to the first frame member. A second frame member has a third side and a fourth side connected to the first frame member at a hinge such that the second frame member can move relative to the first frame member between a first position where the first side is connected to the third side and a second position where the second side is disposed adjacent the fourth side. A method of using the mop is also provided.

Abstract: A method of using a filter and a mop bucket comprises removably installing a filter in a mop bucket; filtering a liquid through the filter to capture dirt in the filter; removing the filter from the bucket; connecting a hose to an outlet on the filter; backflushing clean water through the filter; and removably installing the filter in the mop bucket. The filter comprises a first layer of felt and a second layer of felt with a layer of sand is disposed between the first layer of felt and the second layer of felt. A mop bucket comprises a first compartment and a second compartment where the filter is located in a fluid movement path between the first and second compartments.

Abstract: A scale and cover comprises an electronic scale comprising a scale tray and a user control and a first alignment mechanism. A cover for removably receives the electronic scale where the cover defines an aperture communicating the exterior of the cover with the electronic scale. The cover comprises a second alignment mechanism that engages the first alignment mechanism. A tray comprises a leg that is inserted through the aperture and is supported by the scale tray.

Abstract: A sink extender has a sink comprising a removable drain pan that may be connected to a conduit. An attachment mechanism connects the sink to a support. At least one tool holder supports an elongated handle of a janitorial tool over the sink. A method of using a sink extender comprises mounting the sink extender comprising a sink that drains into a flexible hose and at least one tool holder to a support surface; running the hose to a traditional sink such that water may drain from the sink to the traditional sink by gravity; securing a wet tool to the at least one tool holder such that the tool drains into the sink.

Abstract: The mop frame comprises a first plate pivotably connected to a handle attachment at a first pivot. A second plate is pivotably connected to the first plate at a second pivot such that it is movable between a first position where the second plate is substantially coplanar with the first plate and a second position where the first plate is substantially parallel to the second plate and is disposed on top of the second plate. A latch secures the first plate to the second plate when the second plate is in the second position.

Abstract: A drive provides rotational movement and linear movement to an output. A first gear is operatively connected to the output, such as a roller. A drive assembly comprises a first cam surface, a second cam surface and a second gear. The first cam surface engages a first follower where the first follower is operatively connected to the output such that linear movement of the first cam follower results in linear movement of the output. The second cam surface engages a stationary follower. The second gear engages the first gear. The drive assembly rotates over a range of motion such that for a first portion of the range of motion the drive assembly causes the rotational and linear movement of the output and rotation of the drive assembly for a second portion of the range of motion causes only the rotational movement of the output.
