Abstract: A mobile floor cleaner that includes a moveable housing, a cleaning head operably supported by the moveable housing, one or more solution generators configured to receive a feed liquid and to generate a cleaning solution from the feed liquid by application of acoustic energy and/or nanobubble generation, and control electronics configured to operate the one or more solution generators.

Abstract: Embodiments of the invention provide a cleaning apparatus, such as a battery-powered vacuum cleaner, that has a body and a cleaning wand. The apparatus operates in a multiple power mode, uses a wireless system to allow an operator interface to be provided on the cleaning wand and/or uses a motion detector on the cleaning wand to operate the cleaning apparatus in an intelligent manner. In cases where the cleaning apparatus is a battery-powered apparatus, the use of a multiple power mode, wireless system and/or a motion detector helps to extend the life of a battery.

Abstract: A temperature control system for a vehicle that defines a load space for supporting cargo. The temperature control system includes a refrigeration unit that has a refrigeration circuit, and a heating system that has a heating circuit. The refrigeration circuit includes a prime mover and a cooling coil that selectively cools an airflow entering the load space. The heating circuit includes a pump that circulates a coolant fluid through the heating circuit, a dedicated heater that heats the coolant fluid, and a heating coil that selectively heats the airflow entering the load space. The temperature control system also includes a controller that detects conditions of the load space, and that engages one of the refrigeration unit and the heating system to condition the load space in response to the detected conditions.
