A vacuum cleaner that includes a suction source configured to generate a suction airflow, a dirt collector in fluid communication with the suction source and configured to separate debris from the suction airflow and the dirt collector is configured to store the debris separated from the suction airflow. The vacuum further includes an infrared sensor operable to output a signal corresponding to a distance to an amount of debris stored in the dirt collector, a controller that receives the signal, and the controller is operable to determine a fill level stored in the dirt collector based on the signal. A visual display displays the fill level stored in the dirt collector.

The present disclosure provides a surface cleaning apparatus that includes a housing adapted for movement over a surface to be cleaned and a headlight having at least one light emitting element internal to the housing. A light pipe is integrated with a cover for a brushroll, and conveys light emitted from the light emitting element to an exterior of the housing. Methods for operating the headlight are also disclosed.

An amalgamated handheld vacuum dusting attachment having a housing shaped similar to a computer mouse for hand or distant cleaning featuring a crevice tool, a bristled brushing tool, and a non-bristled detachable cap having an ergonomically shaped top. Separated suction vents are provided for the crevice and bristled tools in order to provide maximum suction, and 360° rotatable wheels, lights, battery chamber, on/off switch, and battery recharge pin port are also provided. Also provided is a padded wrist support end cap and integrated swiveling end coupling nozzle, which can be detached for use as an independent brushless vacuum dusting device. An additional 360° manually rotating stabilizing wand, and independent accordion hose with ergonomic grip disk and handled vacuum attachment for use with aforesaid dusting attachment, are provided.

The present disclosure discloses an electric dust blower which includes a shell, a control panel, a battery module, a fan, an illumination lamp, and air outlet nozzles, where the shell includes two half shells capable of being spliced together left and right; the battery module is disposed at a lower portion of a mounting chamber; the fan is disposed at a rear portion of an air chamber and is close to an air inlet; the illumination lamp is mounted in a mounting hole and exposed out of a front end face of a main body; and the air outlet nozzles are detachably mounted at and connected to an air outlet.

Provided is a method, performed by a cordless vacuum cleaner, of automatically adjusting the strength of a suction power of a suction motor. More specifically, the method may include obtaining data about a flow path pressure measured by a pressure sensor, obtaining data related to a load of the brush apparatus through a load detection sensor, identifying a current usage environment state of the brush apparatus by applying the data related to the flow path pressure and the data related to the load of the brush apparatus to an AI model stored in a memory of the cordless vacuum cleaner, and adjusting the strength of the suction power of the suction motor, based on the identified current usage environment state of the brush apparatus.
