A scrub plate system, a vacuum rail system, and a control system for an irregular surface cleaning system, an irregular surface cleaning system, process, and methods of use are presented. The cleaning system presented herein is designed for clearing surfaces of structures. More specifically, but without limitation, the present cleaning system is designed and configured to clean the surfaces, inside and outside, of wind turbines and the corresponding structure. More specifically, and without limitation, the present disclosure relates to a surface cleaner for cleaning surfaces. More specifically, and without limitation, the present disclosure relates to cleaning surfaces of an irregular surface. More specifically, and without limitation, the present disclosure relates to cleaning a surface of an irregular surface where the target surface is at an inconvenient altitude or location.

The present disclosure provides systems and methods for cleaning a lens of an imaging device during a surgical procedure within an individual. The imaging device comprises a lens, and the wiping object is positioned a distance away from the imaging device that is configured to contact and move along a path of the device in order to clean it. The present disclosure provides methods for initiating automated cleaning of a lens during a procedure comprising using an eye tracking device fitted and coupled to an individual that may track the movements of the individual to actuate cleaning.

Provided is a tool that includes a handle assembly including a top portion and a bottom portion. The tool also includes a lock plate disposed between the top and bottom portions and having a deflectable arm having a free end biased towards the top portion, a fixed end opposite the free end, an inner edge, an outer edge, and a detent near the free end and the inner edge. The tool additionally includes a blade having first and second ends, an indent in a bottom surface of the blade near the first end for engaging the detent in a closed position, and a ramp on the bottom surface near the indent defining a reduced thickness portion of the blade that reduces in thickness from the indent towards an edge of the blade to reduce contact between the detent and the blade during rotation of the blade.

A trowel cleaning device cleans mortar that has set on the serrated edge of the trowel. The trowel cleaner uses a rectangular solid block member that has a ridge pattern on at least the first face and can also be included on one or more additional faces of the block up to all six of its faces. Each ridge pattern corresponds to a serration pattern on a trowel in both size and shape so that as the serrated edge of the trowel is pulled through the ridge pattern, the ridge pattern scrapes off any mortar that has set onto the serrated edge.

A floor scraper hand tool includes an elongated handle, a concave scraper blade, and a guard. The elongated handle is at least two feet long and defines first and second distal ends. The concave scraper blade is coupled proximate the first distal end and includes first and second scraping edges having different forms. A guard at least partially covers one of the first scraping edge or the second scraping edge. The concave scraper blade is coupleable to the elongated handle in a first position in which the first scraping edge is opposite the second distal end of the elongated handle and in a second position in which the second scraping edge is opposite the second distal end of the elongated handle. The guard at least partially covers the first scraping edge in the second position and at least partially covers the second scraping edge in the first position.

Devices are methods are disclosed for a ladder cleaning device. The ladder cleaning device comprises a number of rings. The rings are adapted to be arranged around rungs of a ladder. A cord passes through a hole in each of said rings. The device further comprises at least one attachment device adapted for attaching said cord to the ladder. The ladder cleaning device may be in the form of a kit of parts to allow retrofitting on the ladder.

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.

A drone for cleaning an outer wall of a high-rise building is configured to float and move in the air. The drone includes a drone main body and a floating transfer unit for floating and moving the drone main body in the art. The drone main body has a camera unit provided to photograph the exterior of a building and driving wheels on one surface thereof to be guide to the exterior of the building. The drone main body further has a buffer angle member to cushion an impact with the building and a washing nozzle unit which sprays water onto and washes the exterior of the building. Accordingly, by cleaning the exterior or a window of a skyscraper using the drone, there are the effects of reducing the costs of cleaning a skyscraper, simplifying a cleaning operation, preventing human accidents due to falls, and reducing cleaning time.

Scrapers for removing adhered material from surfaces employ continuous and discontinuous material removal edges to remove different types of material. Continuous and sometimes discontinuous material removal edges are constructed and arranged to conform to the curvature of a surface from which material is to be removed, when a user forces the scraper against the surface. Some scrapers include multiple material removal edges designed to simultaneously contact the surface. The use of multiple points of contact combined with locations of handles provide stable designs that reduce hand and wrist strain.

A grill-cleaning tool has a water-absorbent layer fabricated from a material that is suitable for transferring a volume of water. A fire-resistant layer is disposed outwardly of the water absorbent layer. A scrubbing outer layer fabricated from a metallic-mesh material covers both the fire-resistant layer and the water-absorbent layer. The water-absorbent layer and the heat-resistant layer may be incorporated into a single unit or may be separate layers. Fasteners are provided for assembling the layers together to form an assembled grill-cleaning tool.
