A lawn debris vacuum machine having a mobile housing with an inlet chute and a discharge chute, and a motor mounted on the housing that is connected for rotatably driving a vacuum impeller disposed in the housing between the inlet chute and the discharge chute. A thrasher protrudes into the inlet chute and is rotatably driven from the motor to break up debris in the inlet chute which would otherwise be sufficiently large enough to block the inlet chute. A rotating brush is mounted to the housing at the opening of the inlet chute for brushing debris into the inlet chute. The brush is rotatably driven in a direction opposite to the forward direction of the machine's progress.

Provided are a cleaning robot and a method for traveling along an edge, and a readable medium. The cleaning robot includes a body, where a rolling brush and a side brush are provided at a bottom of the body, the rolling brush and the side brush are transversely arranged at a front end of the cleaning robot, and one end of the rolling brush and the side brush are respectively arranged close to edges of two sides of the body; the cleaning robot further includes a control module and a ground medium identification sensor for detecting a type of a work surface, where the ground medium identification sensor sends a detection signal to the control module, and the control module controls the cleaning robot to travel along an edge with one side edge of the body according to the detection signal.

A sweeper/vacuum ride-on cleaning system includes a vacuum and sweeping mechanism using a sweeper brush and vacuum brush in one cleaning head. A caster leveling system is used for setting the level of the head above the floor. A single motor drive system using a two-sided belt is used for driving the sweeper brush and vacuum brush. A dust management system using holes adjacent to a debris try for holding debris in the tray. A pivoting door access assembly is used for allowing the sweeper brush and vacuum brush to be accessed and removed from the side of the cleaning head. Finally, a bag cage with holes throughout each of its supporting surfaces is used for holding the vacuum bag and allowing air to escape from all sides of the bag to increase vacuum efficiency.

A vacuum cleaner is provided. The vacuum cleaner includes a cleaner body generating a suction force, and a suction unit comprising a suction chamber opened to suck foreign materials by the suction force. The suction unit includes a brush drum partially protruding toward an outside of the suction chamber within the suction chamber and provided rotatably, and a blade provided to collect foreign materials as extended along an extending direction of the brush drum while being spaced apart leaving a gap from the brush drum inside the suction chamber, and including a transformable portion to be transformed to widen the gap.

A surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.
