Abstract: A device for cleaning debris from a target surface. The device has a sole plate with permanent cleaning material, such as bristles, and a removable/replaceable pad. The device also has a replaceable, on-board supply of cleaning solution. The pad/cleaning solution may be replaced when depleted and replaced with a new pad/cleaning solution or may simply be replaced with a new pad/cleaning solution when that pad/cleaning solution is more suitable for a particular cleaning task.

Abstract: A cryogenic fluid cylinder includes an inner vessel for holding cryogenic fluid, a cylindrically shaped outer vessel having a vertical longitudinal axis surrounds the inner vessel and forms an insulating space there between, and operating controls located on a top of the outer vessel. Customer or end user operating controls include a liquid-use valve for selectively dispensing liquid cryogen, a pressure-building valve for selectively controlling a pressure building circuit, and a gas-use valve for selectively dispensing cryogen gas. Supplier or maintenance personnel operating controls include an economizer regulator for selectively setting at least one desired pressure of the inner vessel, a vent valve for selectively venting cryogen fluid, and a vacuum pressure port for indicating vacuum pressure between the vessels. The end user controls are located on a front side of the outer vessel while the supplier controls are located on a rear side of the outer vessel.
