Abstract: A roller assembly tool for a cleaning apparatus that includes a suction assembly and a liquid delivery system includes a support body carrying a portion of a liquid conduit and a portion of at least one airflow passage. The liquid conduit is configured to be in fluid communication with the liquid delivery system and the portion of the at least one airflow passage configured to be in fluid communication with the suction assembly. The support body includes first and second arcuate guides that define an open end. A roller is rotatably coupled to the support body proximate the open end. At least one inlet of the at least one airflow passage is defined between at least one of the first and second arcuate guides and a surface of the roller. An outlet of the liquid conduit is defined between the first and second arcuate guides proximate the roller.

Abstract: An air purifier and a passive humidity module for inside air. The air purifier includes a housing and an air purifier air outlet. The passive humidity module is disposed at least partially on the air purifier air outlet. The passive humidity module includes a housing assembly defining an air inlet and an air outlet, a water tank supported by the housing assembly, a wick filter reservoir fluidly coupled to the water tank, at least one gutter fluidly coupled to the water tank, and a wick filter disposed in the wick filter reservoir and supported by the housing assembly. The air inlet is at least partially aligned with the air purifier air outlet. The passive humidity module includes an airflow path flowing between the water tank and the wick filter, and fluidly connecting the air inlet and the air outlet.
