  • Publication number: 20140100736
    Abstract: A control method of a robot cleaner for traveling to clean includes checking information about a predetermined traveling pattern; determining a traveling trajectory based on a traveling speed; generating a traveling pattern based on the determined traveling trajectory and the information about the predetermined traveling pattern, wherein the traveling pattern includes a first straight path, a first rotation path connected to the first straight path and for rotation in a first direction, a second straight path connected to the first rotation path, and a second rotation path connected to the second straight path and for rotation in a second direction; and repeatedly traveling along the generated traveling pattern at regular intervals. Therefore, since the robot cleaner performs cleaning without scattering dust, the efficiency of cleaning may be improved.

The cleaning pad assembly has a rigid upper plate and a flexible disposable bottom pad having a cleaning contact surface. The contact surface carries a plurality of spaced parallel pad ridges separated by pad grooves that matingly engage between the tread ridges of the escalator steps and cause dislodgement of the accumulated debris. The cleaning pad assembly can be secured on a hand-held cleaning tool or on a motorized cleaning tool with rotating brushes and a vacuum.

  • Publication number: 20120246862
    Abstract: A piezoelectric debris sensor and associated signal processor responsive to debris strikes enable an autonomous or non-autonomous cleaning device to detect the presence of debris and in response, to select a behavioral mode, operational condition or pattern of movement, such as spot coverage or the like. Multiple sensor channels (e.g., left and right) can be used to enable the detection or generation of differential left/right debris signals and thereby enable an autonomous device to steer in the direction of debris.

  • Patent number: 8239999
    Abstract: A mop assembly includes a handle having a control member connected to a lower end thereof and the control member is located within a connection unit which is connected to the handle. A locking unit is connected to outside of the connection unit and is hooked to a main body. The main body includes a case in which a tank, a steam generation device and a pivotal member are located therein. An operation bar is pivotably connected to the case. The pivotal member is able to activate the steam generation device by pushing the handle downward. The main body can be disengaged from the locking unit and used individually. The steam generation device can be activated by operation of an operation bar on the main body.

  • Patent number: 8201296
    Abstract: Floor treatment cleaning system (3) for a floor cleaning machine (1). The floor treatment cleaning system includes at least two treatment elements (7a, 7b) wherein each treatment element is equipped with cleaning means (11) and is eccentrically driven by driving means (15A) via at least two synchronized eccentric pivots (8), characterized in that the respective pivots revolve around their main rotation axes (13) in such a way that the at least two treatment elements perform opposite movements thereby transporting residues on the floor in a desired direction and balancing engine masses and friction. The treatment elements (7a, 7b) can be positioned in different ways: transversely relative to the moving direction of the machine (1) and parallel behind each other, transversely relative to the moving direction of the machine (1) and next to each other and in a V-shape or arcuate with the opening in the moving direction of the machine.

  • Publication number: 20120137464
    Abstract: A powered mopping and cleaning machine is described. The machine includes a recovery tank, a filter assembly, a fresh water tank assembly, a vacuum assembly, a battery charger assembly, a control assembly, and a deck assembly. The machine is adapted to clean floors and more especially flat hard floors by means of providing a cleaning fluid to a rotating brush and by vacuuming resultant dirty fluid from the floor. The powered mopping and cleaning machine is adapted to replace the use of a conventional mop and mop bucket. Use of the powered mopping and cleaning machine is designed to result in decreased labor, increased efficiency, and decreased cleaning cost as compared to the use of a standard mop and mop bucket. The powered mopping and cleaning machine, although self-contained, will preferably fit into the same storage space that is otherwise allotted to store a conventional mop and mop bucket.
