An autonomous vacuum cleaner comprising a main body defining a first axis and housing a dirty air inlet, a clean air outlet, an airflow path between the dirty air inlet and the clean air outlet and a separating apparatus arranged in the air flow path between the dirty air inlet and the clean air outlet, the separating apparatus defining a second axis, wherein the separating apparatus is oriented so that the second axis is substantially parallel with the first axis of the main body and wherein a portion of the separating apparatus protrudes from a forward portion of the main body of the vacuum cleaner.

The present disclosure describes a vacuum-excavation apparatus that is connectible to a vehicle. The vacuum-excavation apparatus comprises a vacuum tube with an input end; a vacuum assembly for generating a suction force at the input end and drawing a stream of fluidized debris-material into the vacuum tube. The apparatus also includes a boom assembly for supporting the vacuum tube and a tank for receiving the stream of fluidized debris-material from the vacuum tube. The tank provides a boom mount for pivotally connecting the boom assembly and for providing fluid communication between the vacuum tube and the tank. The apparatus also includes an evacuation tube for providing fluid communication between the tank and the vacuum assembly and for distributing at least a portion of stress-loads that are generated by the boom assembly.

A high-speed Hall-less three-phase vacuum cleaner motor may include an iron core with a central circle, a rotor running through the central circle, a first end cap for fixing one end of the iron core, a second end cap mating with the first end cap and fixing the other end of the iron core, a movable impeller located at one side of the second end cap, an impeller cover receiving the movable impeller and fixed on the second end cap, a fixed impeller located between the second end cap and the movable impeller, and a circuit board. The circuit board may be provided with a Hall sensor-less circuit cooled by wind output by the motor, and the rotational speed of the motor controlled by the Hall sensor-less circuit is higher than 80000 rotations per minute. The structure is simple, the appearance is beautiful, and the reliability is high.

A cleaner holder includes a first body having a charging terminal to charge a cleaner; a second body connected to the first body, configured to support the cleaner and having an accommodation space in which a battery is accommodated; and a locking part rotatably connected to the first body and configured to fix the cleaner, wherein when force having predetermined magnitude is applied to the locking part in one direction, the locking part is rotated in a first direction to be coupled to the cleaner, so that the cleaner is fixed, and wherein when force having predetermined magnitude is applied to the locking part in the other direction, the locking part is rotated in a second direction opposite to the first direction to be uncoupled from the clean.

A steam generator includes an inlet configured to receive a liquid (such as water); a heating element for converting the liquid into a vapor (such as steam), the vapor bearing particles such as mineral deposits formed by the converting of the liquid; an outlet in fluid communication with the inlet, the outlet configured to discharge filtered vapor and having a size on the order of larger ones of the particles; and a filter structure adjacent to the outlet to filter the larger particles out of the vapor to produce the filtered vapor for discharge from the outlet. By action of the filter structure, larger particles are prevented from reaching the outlet, reducing clogging and extending the usable lifetime of a small appliance containing the steam generator. The filter structure may include spaced-apart members such as posts or pillars extending perpendicularly in a planar fluid flow passage.

An indication lighting device provided is capable of reducing the number of electric wiring from a fixed, part to a moving part when an indication part is provided in the moving part's side. The indication lighting device makes indication by emitting light from a light source arranged in a fixed part to an optical waveguide arranged in a moving part, reflecting the light incident on the optical waveguide by reflection surfaces of prisms of the optical waveguide to an indication part provided in a tip side of the optical waveguide to be propagated, and emitting the light propagated inside the optical waveguide through the indication part.

A cleaner holder includes a charging stand having a battery accommodating space formed therein in which a battery detachably mounted to a cleaner is accommodated, wherein the battery accommodating space includes: a charging port selectively in contact with a battery terminal provided in the battery; a battery guide configured to perform guiding such that the battery comes into contact with the charging port; and an inlet which extends toward an upper side of the battery guide and through which the battery is inserted or withdrawn, and an upper end of the inlet is higher than an upper end of the battery accommodated in the battery accommodating space.
