    摘要： A control method for carpet drift in robot motion, a chip, and a cleaning robot are disclosed. The control method includes: performing fusion calculation on a current position coordinate of the robot according to data sensed by a sensor every first preset time, calculating amount of drift, relative to a preset direction, of the robot, according to a relative position relationship between a current position and an initial position of the robot, and accumulating to obtain a drift statistical value; and calculating the number of acquisitions of the position coordinate within a second preset time, averaging to obtain a drift average value, then determining a state of the robot deviating from the preset direction according to the drift average value, and setting a corresponding Proportion Integration Differentiation (PID) proportionality coefficient to synchronously adjust speeds of left and right drive wheels of the robot while reducing a deviation angle of the robot. The control method improves accuracy in detecting carpet drift of the robot, thereby effectively controlling the robot to maintain a good linear walking effect.

    摘要： The invention relates to a mobile floor cleaning appliance (10) comprising a housing (12) containing a cleaning tool (22), and a handle holder (32) which is arranged on the housing (12) and can be connected to a handle for guiding the appliance along a floor surface to be cleaned. The aim of the invention is to improve the mobile floor cleaning appliance (10) in such a way that the handle holder (32) can be reliably locked in an idle position and can be switched in a simple manner from the idle position to a working position. According to the invention, the handle holder (32) is mounted on the housing (12) in such a way that it can be pivoted about two pivoting axes (38, 40) which are inclined or perpendicular in relation to each other, and can be locked in an idle position. At least one locking element (72, 79) is associated with each of the two pivoting axes (38,40) for the locking of the handle holder (32), and the locking of the handle holder in relation to the two pivoting axes (38, 40) can be released by pivoting the handle holder (32) out of the idle position about one of the two pivoting axes (38, 40).

    摘要： A surface cleaning apparatus comprising a body (1; 106) having a forward compartment (9; 114) with an opening in a lower surface thereof; and an elongate rotatable brush arrangement (11; 116) provided within and extending across the forward compartment (9; 114) of the body (1; 106). The brush arrangement (11; 116) has bristles adapted to extend through the opening in the forward compartment (9; 114) as the brush arrangement (11; 116) is rotated. The lower front region of the body (1; 106) is chamfered to increase the extent to which the bristles protrude from the body (1; 106) in the region of the chamfer such that, when the apparatus is inclined relative to a surface to be cleaned, contact between the bristles and the surface to be cleaned is increased.

    摘要： The improved carpet cleaning machine (10), intended for use with "dry" carpet cleaning systems using dampened particles (17), can be used for carpet "brushing" for dirt removal and for later vacuuming to remove dirt-laden particles (17). The machine (10) has a concentrically-mounted cyclone separator (21a) and a conical screen filter (23a) in series. The separator (21a) has air (25) flowing through it downwardly along a vortical path (37) and then upward along another path (45). Such upward-flowing air impinges on the outer surface (47) of the screen filter (23a) and many particles (17) adhering to such filter (23a) are dislodged. One or more additional media (67, 87) may be used to remove very fine particles (17).
