    • An apparatus for collecting leaves includes a mobile carrier and a leaf raking mechanism, hollow chute, blower unit and exhaust duct on the mobile carrier. The mobile carrier is movable forwardly over a surface during performance of leaf collection operations. Forced air flow produced by the blower unit is directed through the hollow chute from a rear end to a front end thereof past the leaf raking mechanism so as to create a vacuum effect in the hollow chute that assists the leaf raking mechanism in gathering leaves from the surface and delivering the leaves into the hollow chute where the leaves become entrained in the forced air flow directed to and through an outlet of the hollow chute and through the open top of a leaf collection bag, and into the bag, being disposed below the outlet of the hollow chute.
    • 收集叶片的装置包括可移动的载体和移动载体上的叶耙机构,中空溜槽,鼓风机单元和排气管。 在执行叶收集操作期间,移动载体可以在表面上向前移动。 由吹风机单元产生的强制空气流通过空心滑槽从其后端到其前端经过叶片耙式机构,以便在空心滑槽中产生真空效果,以帮助叶耙机构从叶片收集叶片 表面并将叶片输送到空心斜槽中,其中叶片被夹带在被引导到并穿过中空滑槽的出口并通过叶片收集袋的开口顶部的强制空气流中,并且进入袋中,设置在出口下方 的中空滑槽。

    • An autonomous floor-cleaning robot comprising a housing infrastructure including a chassis, a power subsystem; for providing the energy to power the autonomous floor-cleaning robot, a motive subsystem operative to propel the autonomous floor-cleaning robot for cleaning operations, a command and control subsystem operative to control the autonomous floor-cleaning robot to effect cleaning operations, and a self-adjusting cleaning head subsystem that includes a deck mounted in pivotal combination with the chassis, a brush assembly mounted in combination with the deck and powered by the motive subsystem to sweep up particulates during cleaning operations, a vacuum assembly disposed in combination with the deck and powered by the motive subsystem to ingest particulates during cleaning operations, and a deck adjusting subassembly mounted in combination with the motive subsystem for the brush assembly, the deck, and the chassis that is automatically operative in response to an increase in brush torque in said brush assembly to pivot the deck with respect to said chassis. The autonomous floor-cleaning robot also includes a side brush assembly mounted in combination with the chassis and powered by the motive subsystem to entrain particulates outside the periphery of the housing infrastructure and to direct such particulates towards the self-adjusting cleaning head subsystem.

    • Disclosed herein is a vacuum cleaner having a housing defining first and second ports. The vacuum cleaner also includes a cap assembly. The cap assembly includes a cap head to close the first port such that airflow is directed via a flow path to the second port, a sound-influencing material, the sound-influencing material removably held to the cap head and disposed within the flow path to reduce noise effected by the airflow. The flow path is configured to cause the airflow to pass through the sound-influencing material and the flow path to the second port. The sound-influencing material is removable to allow cleaning of the sound-influencing material. The sound-influencing material may include a reticulated foam roll disposed in the frame to diffuse the discharge airflow.
