The at least one cleaning module includes a spray system having a manifold connected to a source of fluid and a plurality of spray bars fluidly coupled to the manifold, and an adjustable height spray system configured to move the manifold and the plurality of spray bars up and down with respect to the conveyor system.

Leave No Trail! is the only product of its kind that is developed specifically to spray off any debris from the bottom of shoes to protect both indoor flooring and the overall aesthetic of the shoe, post necessary cleaning. Leave No Trail! is uniquely designed with an avant-garde water spraying system, is carefully crafted with durable, high-quality materials to ensure long-term sustainability and the unit can be used to clean any and all footwear design, regardless of personal foot size and/or sensitivity of the shoes' fabric.

A pressure washer includes a motor for a high-pressure pump, a battery pack to supply the motor with energy, a battery compartment for the battery pack and a housing. The battery compartment has an insertion opening through which the battery pack can be inserted into the battery compartment. The battery compartment has a base body. The pressure washer has a protective element for protecting the battery compartment from liquid, which is arranged radially outside the base body of the battery compartment and has a protective surface. The battery compartment has a projection which projects radially beyond the base body of the battery compartment. The protective surface points in an insertion direction. The pressure washer has at least one angular sector around the insertion axis in which the protective element axially overlaps the projection such that the projection lies in front of the protective surface with respect to the insertion direction.

The present disclosure relates to a substrate treatment apparatus including: a substrate treatment apparatus including: a chuck base rotating together with a substrate in a state of supporting the substrate thereagainst; a fluid supply unit for supplying treatment liquid to the substrate; a bowl assembly having a plurality of bowls that overlap outward in a radial direction with respect to the center of the substrate in such a way as to surround the chuck base; an ascending and descending unit for moving the bowl assembly up and down; and a shutter unit disposed on top of the outermost bowl of the bowl assembly to adjust a radius of an air flow inlet through which air flow passes toward the substrate.

A mobile high-pressure cleaning apparatus is provided with a vehicle trailer, on the chassis of which at least two running wheels are held so as to be rotatable, and with a high-pressure cleaning appliance having a motor and a pump, and also with at least one water storage tank for storing water for the high-pressure cleaning appliance. So that water can be provided to the apparatus from the at least one water storage tank or from a water supply mains, without risk of water from the water supply mains being returned thereto, the high-pressure cleaning apparatus has a decoupling tank with at least one inlet which can be connected to the water supply mains, and at least one outlet which is connected to the high-pressure cleaning appliance and to at least one water supply tank via a shut-off member which can be actuated by the user.

A mobile cleaning system to be used for cleaning organic liquids from a hard surface includes tanks for storing water, and for storing used, dirty water after cleanup. A water-based cleaner is sprayed onto the spill, which can be, but need not be, done in connection with the cleanup system. A high throughput vacuum system removes the hot water and the spill materials concurrently as the hot water is applied to the treated area. The vacuumed liquids are stored in an on-board tank for later disposal.

A spray gun includes a gun body, a flow passage, a fluid driving element, a control module, a switch assembly and a battery pack. The control module is configured to obtain power information of the battery pack and/or working state information of the fluid driving element, and display the power information of the battery pack and/or the working state information of the fluid driving element through a visual interface module.

A washing system may include a washer, sprayer, emitter, sensor, and display. The washer may include a housing and one or more supports configured to receive a product associated with unwanted materials. The sprayer may be configured to remove a first quantity of unwanted materials. The emitter may be configured to remove a second quantity of unwanted materials. The sensor may be configured to detect a third quantity of unwanted materials. The display may be configured to indicate a fourth quantity of unwanted materials.

This high-pressure cleaning device comprises: a main body; a cover covering the upper portion of the main body; a cleaning tank formed between the main body and the cover; and a cleaning assembly disposed in the cleaning tank, wherein the cleaning assembly comprises a base in which an object to be cleaned is disposed and a first cleaning module for cleaning the object to be cleaned. The first cleaning module comprises: a cleaning liquid supply pipe; a rotating disc comprising a first surface that is perpendicular to the lengthwise direction of the cleaning liquid supply pipe, a second surface formed at the opposite side to the first surface, and a side surface formed between the first surface and the second surface; a plurality of cleaning nozzles formed in parallel to the rotary shaft of the rotating disc; and a plurality of propulsion nozzles formed to be inclined with respect to the rotary shaft of the rotating disc, wherein the rotating disc can be rotated due to the injection from the propulsion nozzles.
