Abstract: A handheld suction device may provide an ergonomic and convenient device for cleaning a variety of floor surface soils, including liquid soils. In different configurations, the device may provide a variety of different features to efficiently collect and hold liquid removed from the floor surface and/or prevent vacuum motor flooding if the operator over rotates the device when filled with liquid. In some applications, the handheld suction device provides an interchangeable system that allows the operator to switch between different suction attachments designed for picking up liquid soil and solid soil.

Abstract: A liquid treatment system comprising a main flow path, a bypass flow path fluidly coupled to a main flow path, and a liquid conditioning module fluidly coupled with the bypass flow path with a reservoir holding treatment components added to liquid entering the reservoir from the bypass flow path to form a treatment solution. A flow rate of liquid in the main flow path is controlled independently of a flow rate of treatment solution flowing into the main flow path. A dispensing component fluidly coupled to the liquid conditioning module controls flow rates or pressures of treatment solution flowing out of the bypass flow path and into the main flow path independently of flow rate of liquid flowing in the main flow path. The liquid treatment system comprises a drop tube system suspended in treatment solution having the highest treatment concentration.
