Abstract: A liner for an above-ground frame pool is provided. The liner includes a bottom wall and a sidewall coupled to the bottom wall and defining a water cavity together with the bottom wall. The sidewall has a substantially cylindrical shape, and the sidewall includes a translucent portion facilitating viewing between the water cavity and an exterior of the above-ground frame pool. The translucent portion has a substantially semi-cylindrical shape.

Abstract: A pool cleaner for use in a pool may include a housing, a driving assembly, a traction assembly, and a filtration assembly. The driving assembly may include an inlet conduit configured to receive pressurized water, an impeller in fluid communication with the inlet conduit, an outlet conduit in fluid communication with the impeller, and an outlet nozzle coupled to the outlet conduit and may be configured to eject the pressurized water upward from the housing and into the pool in a parallel or oblique ejection direction relative to a vertical axis. The traction assembly may be coupled to the impeller to drive the housing across the pool and the filtration assembly may be configured to filter water from the pool.

Abstract: An inflatable spa is disclosed having improved strength. A water cavity of the inflatable spa may receive massaging air bubbles and/or jetted water.

Abstract: An above ground frame pool is disclosed including a frame assembly and a liner supported by the frame assembly. The frame assembly includes a plurality of horizontal pipes, a plurality of vertical pipes, and a plurality of T-shaped joints. The joints may lack mechanical fasteners with adjacent pipes or corresponding apertures. The joints may be one-piece or multi-piece structures. Such joints may be water-resistant and convenient to manufacture, assemble, disassemble, and store.

Abstract: A pool cleaner equipped with a rotating brush assembly is disclosed. The brush assembly is removably coupled to the pool cleaner using clamps that are readily accessible, supported by the pool cleaner, and operable by hand. The clamps may be manipulated between a ready configuration, a loaded configuration to receive a brush assembly, and a locked configuration to secure the brush assembly.

Abstract: A pool cleaner equipped with a joint and a water inlet hose is disclosed. In a rotatable or use configuration, the water inlet hose is freely rotatable relative to a housing to avoid entanglement. In a locked or non-use configuration, either the joint or the water inlet hose is fixed relative to the housing to facilitate installation and/or removal of the water inlet hose via rotation between the joint and the water inlet hose.

Abstract: An inflatable furniture design has a user-interfacing surface, such as the sleeping surface of an air mattress, which includes a breathable multilayer mesh which separates the user from the underlying air-impermeable sheet. The breathable mesh is made from a material such as 3D fabric, which is resiliently deformable while also allowing for airflow through and around the volume of the mesh material of the breathable interface material. When a person contacts the inflatable furniture, her or his body comes into direct contacts with the breathable mesh. The mesh then resiliently deforms such that airflow through and around the mesh is still permitted. This airflow allows heat and moisture from the user to dissipate through mesh of the breathable interface material. This, in turn, enhances the comfort of the breathable mesh, while also reducing the potential for the proliferation of bacteria and mites on the user-contacting surface.

Abstract: A water treatment system (10) includes an ozone generator (3) combined with an electrolytic chlorine generator (4010) in a compact, efficient and serviceable assembly. The system (10) may include a modular and replaceable ozone generator (3), which allows a damaged or non-functional ozone generator (3) to be quickly and efficiently replaced. In order to protect the ozone generator (3) from damage, a fail-safe drain valve assembly may also be provided which will expel backflowing pool water before it is allowed to backflow into the ozone generator (3). The water treatment system (10) may further include an insulated electrolytic chlorine generator (4010) that mitigates or eliminates leakage current for efficient operation.
