A pole section for temporary assembly with similar pole sections into an elongate pole assembly whereby a user can perform work on a remote worksite elevated by up to 20 m above the user. Each pole section includes a male end and a female end, having a complementary taper to slide into or around the other of a male or female end and form a fluid tight joint with a stiffness similar to or greater than the overall stiffness of the pole. The ends of each pole section include one of first and second complementary coupling parts. The coupling parts cooperate to prevent the pole sections moving relatively towards each other under the weight of overlying pole sections in use to prevent the pole sections jamming A resiliently deformable locking structure is provided in a coupling part by a ring spring.

A robot for cleaning and inspecting wind turbine blades. The robot has a module that adheres to the blade using a vacuum force. The robot also has a cleaning compartment is divided into two sections that are connected by a flexible section. The cleaning compartment is flexible such that it adapts to convex and concave curvatures on the blade.

A cleaning device for removing marks from a surface includes a body of melamine foam sponge having a front side and a rear side opposed to the front side, and a holding layer secured to the rear side of the body of melamine foam sponge to prevent relative movement therebetween. The holding layer is preferably a cloth and more preferably natural or synthetic chamois which can be used to wipe and/or buff the surface after rubbing the body of melamine foam sponge on the surface to remove at least one surface mark. The body of melamine foam sponge can be pre-moistened with a liquid such as a disinfecting solution.

A cleaning apparatus having a cleaning head and a handle. The cleaning head having a paddle with a planar central portion, a plurality of corners, and a peripheral edge. The handle affixed to the cleaning head via hinged connection. The plurality of corners are at a downward angle relative to the central portion. Additionally, the cleaning head includes a compressive material substrate and a cleaning element, the compressive material substrate located between the paddle and the cleaning element.

Extendable cleaning tools are described. The tools include a plurality of pole elements, wherein the plurality of pole elements include an innermost pole element and an outermost pole element, wherein the innermost pole element is moveable relative to the outermost pole element in an axial direction and the innermost pole element and the outermost pole element are not rotatable relative to each other, a clamp arranged at an end of the outermost pole element and configured to selectively engage with a pole element of the plurality of pole elements arranged within the outermost pole element, and a working head assembly attached to an end of the innermost pole element.

A demolition ram, for demolishing glazing, comprises a pusher and a handle connected at its distal end to the pusher. The pusher comprises a support plate, a rubber plating on the distal surface of the support plate, and a reinforcing flange and a boss on the proximal surface of the support plate. At least one handling aperture is through the pusher. The handle has a plate at its distal end. Fasteners removably connect the plate to the boss. A handle extension can be connected to the handle. The handle at its proximal end and the handle extension each comprises a generally textured surface. The demolishing comprises pushing a subpane out of the glazing with the demolition ram by exerting a force with the handle onto the subpane through the pusher. The subpane is then allowed to fall due to its weight, and is caught with a receptacle comprising a mat.

A transverse cleaner head carried from a handle element and having spacer studs on the opposite ends.

A mirror cleaning device configured to effectively and properly clean side-view mirrors or rear-view mirrors having a curved profile on a vehicle. The mirror cleaning device comprises a head connected to an ergonomic handle. The head comprises a connecting bar and a cleaning blade retaining rail. The head is removably attachable to the ergonomic handle via a mechanical fastener. The mirror cleaning device further comprises a squeegee blade. The squeegee blade fits in a groove in the cleaning blade retaining rail. The squeegee blade is configured to move and adapt to the curvature of almost any mirror or glass surface to effectively remove any dirt, dust, water, or other contaminates from the surface of the mirror.
