20080271273 | Powered cleaning appliance - A powered sweeper includes a housing, a brushroll chamber disposed in the housing, a brushroll mounted in a brushroll chamber, a dirt chamber disposed in the housing, a drive motor disposed in the housing, and a driven wheel operatively connected to the drive motor. The brushroll rotates in the brushroll chamber and the dirt chamber communicates with the brushroll chamber such that debris is propelled by the brushroll into the dirt chamber. | 11-06-2008 |
20100088835 | WORM DRIVE ASSEMBLY FOR AGITATOR - A floor cleaning apparatus is disclosed including a nozzle assembly having an agitator cavity and a handle assembly pivotally connected to the nozzle assembly. The apparatus further includes a rotary agitator carried on the nozzle assembly in the agitator cavity. A dirt collection vessel is carried on either the nozzle assembly or the handle assembly. A drive linkage interconnects a drive motor with the rotary agitator. The drive linkage includes a ring gear including a dog clutch receiver and a dog clutch carried on the rotary agitator. The dog clutch engages the dog clutch receiver to interconnect the drive motor and the rotary agitator during normal operating conditions. In the event of an agitator Jam, the dog clutch functions to interrupt drive to the rotary agitator and protect the drive motor, rotary agitator and drive linkage from damage that might otherwise result from the overload. | 04-15-2010 |
20100115719 | SURFACE DEBRIS REMOVAL APPARATUS - This invention relates to a mechanism for use in a device that comprises a system for collecting dirt and debris from a variety of floor and upholstery surfaces. In particular the mechanism lifts and directs unwanted debris particles to a waste reservoir for the purpose of cleaning and grooming floor surfaces. The debris collection mechanism can be, but is not limited to its use in a handle operated cordless motorized floor sweeper to collect and gather unwanted debris and dust. The device includes a head unit that incorporates two easily removable elongate cylindrical rotating cleaning bars that are driven such that they contra rotate, and are positioned close to one another at the forward region of the head unit. A removable debris reservoir, removable rechargeable power source and handle incorporating a device operation switch are also included. | 05-13-2010 |
20100287717 | Autonomous cleaning machine - Disclosed herein is an autonomous cleaning machine with a brush cleaning unit to clean a brush unit. The autonomous cleaning machine includes a main body, the brush unit rotatably provided on the main body, first brush cleaning members contacting the brush unit to move foreign substances wound on the brush unit in a lengthwise direction of the brush unit, and second brush cleaning members contacting the brush unit to remove the foreign substances wound on the brush unit from the brush unit. | 11-18-2010 |
20110000037 | Combination of Carpet-Cleaning Machine and Platform for Transporting the Machine - In a platform-carried carpet-cleaning machine for facilitating transport of the machine, the platform including a machine-supporting base having upper surface extending between an open entry-end and a closed back-end, the upper surface having an entry portion sloping at no more than about 5° with respect to horizontal such that the machine can be driven on and off the platform with application of about the same amount of user force as during carpet-cleaning operations. Inner surfaces of first and second platform sidewalls both include protrusions frictionally engaging the machine side panels and configured to sandwich the machine therebetween to prevent lateral movement of the machine on the platform. A pair of wheels is mounted with respect to the base for rolling the machine on the platform across a floor, each wheel being secured to its corresponding sidewall by an axle which extends therethrough and is molded in place through the sidewalls to facilitate assembly of the platform. At least one skid-resisting projection extends from the lower surface to hold the platform from unintended backward rolling when the machine is driven onto the platform. | 01-06-2011 |
20110107533 | Dust case for sweeper - A dust case is provided for a sweeper that uses a rotary brush to sweep dust particles. The dust case has a casing having a plurality of walls, including a front wall, that together define an interior space, and having an open top and an inlet at a front wall to receive dirt particles. The dust case also includes a cover having a first cover portion for covering the open top of the casing and a second cover portion extending in a forward direction from the first cover portion. A safety bar can be provided extending downwardly from the bottom face of the second cover portion. The dust case can further include a hinge member that connects the cover to the casing in a manner where, when the cover is pivoted so that the first cover portion exposes the interior space, the second cover portion blocks the inlet, and when the cover is pivoted so that the first cover portion covers the interior space, the second cover portion exposes the inlet. | 05-12-2011 |
20110154589 | POWERED CLEANING APPLIANCE - An autonomous cleaning appliance including a housing, a dirt container disposed in the housing, a brushroll disposed in the housing and configured to move dirt into the dirt container, a brush motor disposed in the housing for driving the brushroll, and a power drive assembly mounted in the housing for propelling the appliance. The power drive assembly including a first drive assembly disposed on a first side of the housing, a first drive motor operatively connected to the first drive assembly, a second drive assembly disposed on a second side of the housing (the second side being opposite the first side), and a second drive motor operatively connected to the second drive assembly. A floor sensor system is coupled to the housing for detecting a loss of floor condition and an off edge condition. | 06-30-2011 |
