Abstract: A portable handheld canister vacuum including an upper, central, and lower housing is disclosed. First and second grills can separate the housing sections. An air intake opening can direct air and dirt in a first axial direction to a dirt capturing device in the lower housing. An air propulsion device directs air in a second axial direction opposite to the first axial direction into the central housing and from there into the upper housing. An exhaust opening disposed through the upper housing and leading to the interior region of the upper housing allows air to exit the interior region of the upper housing. The exhaust can exit the upper housing in a direction substantially perpendicular to the first and second axial directions.

Abstract: A vacuum cleaner attachment and a method of control of the vacuum cleaner attachment are described. The vacuum cleaner attachment comprises an ultraviolet light source to irradiate and disinfect various cleaning surfaces. Various embodiments of the attachment include one or more safety features concerning activation, enabling, and disabling of the ultraviolet light source based on various parameters such as distance between the attachment and a cleaning surface, time that such a distance is greater than a predetermined time period, and temperature of the ultraviolet light source in order to enable safe and effective operation of the attachment.

Abstract: An orbital blush for an orbital floor brush machine is provided according to an embodiment of the invention. The orbital brush includes a brush frame adapted to fit to the orbital floor brush machine, a first ring of first bristle tufts of a first length and oriented at a first angle, and a second ring of second bristle tufts of a second length and oriented at a second angle.

Abstract: A disinfecting device is presented having a UV light source for radiation of a cleaning medium to eradicate the medium of infestation agents such as molds, viruses, bacteria and dust mites. The device enhances the disinfection of the medium by providing mechanisms for enhanced penetration of the UV light into the cleaning medium. The device also offers enhanced heat dissipation to promote effective use of the device. Also provided are safety mechanisms to promote the safe and advantageous use of the UV device.

Abstract: A tilt sensor for a cleaning device makes use of an optical sensor to interrupt operation of the device. In one implementation, the tilt sensor shuts off a UV light included in the cleaning device's operations. The tilt sensor includes a housing with at least one chamber defined therein. A sliding or moving element is located in the chamber. The optical sensor is operatively associated with the chamber so that, in response to certain movement of the element within the chamber, the optical sensor signals the tilt sensor to turn off the UV light.

Abstract: A combination vacuum cleaner and ultraviolet disinfecting device is presented having a vacuum for cleaning a cleaning medium, such as a carpet, and a UV light source for radiation of the cleaning medium to eradicate the medium of infestation agents such as molds, viruses, bacteria and dust mites. The device provides a multiple of safety switches to prevent power supply to the UV light source under certain conditions. Safety switches are provided requiring a constant activation of a switch by the user on the device handle, activation of contact switches indicating the device is in contact with the cleaning medium, activation of a switch indicating the device is in an in-use position, and a tilt sensor to prevent power supply to the UV light if the device, or a portion thereof, is tilted beyond a preselected degree.

Abstract: A steerable vacuum cleaner and a method to steer the vacuum is described. The vacuum cleaner include: a base; a handle having a longitudinal axis and including a conduit; and a rotatable coupling pivotally attached between the base and the handle, with the coupling defining an air channel for providing a flow of air from the base to the conduit in the handle. The base of the vacuum rotates about the longitudinal axis while pushing the vacuum by twisting the handle. The rotatable coupling of the vacuum cleaner includes: an inner conduit having an outer surface; a compressible strip disposed on the outer surface of the inner conduit, wherein the strip is disposed the outer surface of the inner conduit; an outer conduit adapted to snugly fit over the strip and the first conduit; and a non-reactive high-viscosity lubricant disposed on the outer surface of the inner conduit adjacent the strip.

Abstract: An air cleaner including touch points is provided according to an embodiment of the invention. The air cleaner includes a chassis and one or more visually coded touch points on the chassis. The one or more visually coded touch points include indicia of user-contactable components of the air cleaner.
