A washing apparatus washes a cleaner having a mop unit formed at a lower portion thereof. The washing apparatus includes a tray configured to form a space to receive the cleaner and washing water. A washing unit is disposed at a lower portion of the inside of the tray in contact with the mop unit. The washing unit includes a first spinning mop protrusion line configured to protrude upwardly, an upper end of the first spinning mop protrusion line being inclined downwardly in a first direction.

A cleaning and/or disinfecting device, including: a rinsing container having a rinsing chamber, the rinsing container having a loading opening for loading with washware to be cleaned; a rinsing chamber door, by which the loading opening can be closed in a fluid-tight manner, wherein the rinsing chamber door is a lift door configured to be displaceable translationally in a height direction of the rinsing container; and a drip collector arranged below the rinsing container in the height direction, the drip collector being configured to be displaced translationally in a direction running transversely to the height direction of the rinsing container, the drip collector being configured to be transitioned from a non-use position overlapping with the rinsing container to a use position protruding past the rinsing container on a loading opening side and from the use position back to the non-use position.

A cleaner includes a first cleaning module including a left spin mop and a right spin mop that come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module that comes into contact with the floor at a position spaced apart from the left spin mop and the right spin mop in a forward-and-backward direction, a body supported by the first cleaning module and the second cleaning module, and a water supply module that supplies water to the first cleaning module. A water tank is disposed inside the body. Water supplied by the water supply module reaches the first cleaning module before reaching the floor.

A cleaner includes a body, a left spin-mop module located on a left side of the body and a right spin-mop module located on a right side of the body, each of the left spin-mop module and the right spin-mop module being rotatable about a first rotational axis to perform mopping, a left spin-drive unit disposed on the left side of the body, the left spin-drive unit being configured to provide a force to rotate the left spin-mop module; and a right spin-drive unit disposed on the right side of the body, the right spin-drive unit being configured to provide a force to rotate the right spin-mop module. Each of the left spin-drive unit and the right spin-drive unit has a second rotational axis that extend in a direction different from the first rotational axis of the respective left spin-drive unit and the right spin-drive unit.

A cleaner includes a body, a left spin-mop module located on a left side of the body with respect to a centerline of the body, a right spin-mop module located on a right side of the body with respect to the centerline of the body, a left spin motor disposed on the left side of the body with respect to the centerline of the body and having a left spin shaft to provide a force to rotate the left spin-mop module, and a right spin motor disposed on the right side of the body with respect to the centerline of the body and having a right spin shaft to provide a force to rotate the right spin-mop module. The left spin shaft and the right spin shaft extend in a parallel direction of the centerline of the body.

A method of flow control is provided. The method includes injecting a liquid onto a wafer via a dispense system. The dispense system includes a plate and an injection hole in the plate. The plate is positioned away from the wafer at a distance and has a diameter equal to or larger than the wafer. A drying gas is injected onto the wafer via the dispense system to push out the liquid. While injecting the drying gas onto the wafer via the dispense system, at least one parameter selected from the group consisting of an inlet flow pressure of the injection hole, the distance and an injection sequence is adjusted so that an interface between the drying gas and the liquid is stable.

Liquid suspensions are disclosed that include superabsorbent polymer suspended within a non-aqueous liquid. The liquid suspensions are capable of being pumped and sprayed onto waste fluids for clean-up procedures. The liquid suspensions can be made by high shear mixing of the superabsorbent polymer with the non-aqueous liquid until the superabsorbent polymer is suspended within the non-aqueous liquid.
