The first deformable flap is disposed at an aggressive angle and the first bristle strip and/or row of tufts is arranged at a passive angle.

Disclosed is a hand-held dish cleaning brush that includes an elongate handle with a scrubbing head at one end, the scrubbing head including a working part of an elastomer integrally formed with a plurality of bristles and with a plurality of scraping projections that are formed as an array of scraping teeth, wherein the bristles are not directly aligned with but off-set from the scraping teeth and pass between the scraping teeth when flexed forwardly or rearwardly toward the scraping teeth.

A cleaning device including a covering hood having a lower surface facing a surface to be cleaned and an inlet on an upper surface thereof, through which contaminants are sucked; an air knife provided on a circumference of the covering hood and having an outlet for spraying high pressure air to the surface to be cleaned; a sweeper installed inside the covering hood and rotated by a driving motor to guide foreign objects swept away from the surface to be cleaned and contaminants floated by the high pressure air injection of the air knife to the inlet; a rotary member including a shaft passing through a circumferential surface of the covering hood and the air knife, and a rotary knob coupled to one end of the shaft to rotate the air knife to adjust an air spray angle.

A robotic cleaning device having a main body, a propulsion system configured to move the robotic cleaning device over a surface to be cleaned, a controller configured to control the propulsion system to move the robotic cleaning device over the surface to be cleaned, at least one rotatable side brush arranged to sweep debris from the surface to be cleaned, and a mechanism configured to at least partly retract the at least one rotatable side brush into a space arranged inside the main body upon receiving a control signal from the controller, such that the rotatable side brush is moved out of contact with the surface to be cleaned.

A surface cleaning apparatus comprising a cleaning head and a brushroll. The cleaning head includes a cleaning head body having an agitator chamber including an opening on an underside of the cleaning head body. The brushroll is rotatably mounted to the cleaning head body such that a portion of the brushroll extends below the underside for directing debris into the opening. The brushroll includes an elongated body extending laterally between a first and second end region, a slit opening extending between the first and second end region, angular stationary teeth extending proximate to an edge of the slit opening, and a cutting blade configured to be at least partially received within the slit opening and to move laterally between the first and second end regions. The cutting blade bar includes teeth that are configured to engage with the stationary teeth to cut hair.

The disclosure discloses a cleaning robot and a cleaning mechanism thereof. The cleaning robot comprises a shell and a cleaning mechanism. The cleaning mechanism comprises a flexible roller, a motor for driving the flexible roller to rotate, a water squeezing roller, a roller brush, and a sewage collection tank. The sewage collection tank is located above the flexible roller. The water squeezing roller is disposed adjacent to the sewage collection tank. The center of the water squeezing roller is disposed in parallel with the center of the flexible roller, and the surface of the water squeezing roller is pressed against the surface of the flexible roller. The roller brush contacts the flexible roller. When the flexible roller rotates, the water squeezing roller presses sewage in the flexible roller into the sewage collection tank. The cleaning mechanism of the disclosure has strong squeezing capability, can reduce energy consumption, and reduce noise.

A cleaning device for cleaning a dispensing nozzle assembly of a beverage dispenser is disclosed. The dispensing nozzle assembly may include a macro-ingredient/diluent outlet and a number of micro-ingredient outlets surrounding the macro-ingredient/diluent outlet. The cleaning device may include a handle, a head end rotatably attached to the handle, a guidance protrusion extending from the head end, a first set of bristles extending from the head end and surrounding the guidance protrusion, and a second set of bristles extending from the head end adjacent to the first set of bristles.

An autonomous cleaning robot (e.g., an autonomous vacuum) may employ a cleaning head for cleaning messes in an environment. The cleaning head may comprise an enclosure with a brush opening at a first side, a mop opening at a second side, and an outlet connected to a vacuum pump. The outlet may open to a cavity within the enclosure. The cleaning head may further comprise a brush roller configured at a front of the enclosure, a mop roller configured behind the brush roller in the enclosure, an actuator connecting the mop roller and brush roller to the enclosure, and a selection flap hinged at a top portion of the cavity. Each of the brush roller and mop roller may be externally exposed at the brush opening and mop opening, respectively, and the actuator may be configured to move the enclosure vertically.

An autonomous cleaning robot (e.g., an autonomous vacuum) may clean an environment using a cleaning head that is self-actuated. The cleaning head includes an actuator assembly comprising an actuator configured to control rotation and vertical movement of a cleaning roller, a controller, and a cleaning roller having an elongated cylindrical length connected to the actuator assembly. The cleaning head also includes a computer processor connected to the actuator assembly and a non-transitory computer-readable storage medium that causes the computer processor to map the environment based on sensor data captured by the autonomous vacuum. The computer processor may determine an optimal height for the cleaning head based on the map and instruct the actuator assembly to adjust the height of the cleaning head.
