SURFACE CLEANING APPARATUS HAVING A FLUID DISTRIBUTOR
20230053712 · 2023-02-23 · ·

A fluid delivery system for a surface cleaning apparatus includes a fluid container configured for storing a fluid, a fluid distributor configured for delivering the fluid to a surface to be cleaned, and a flow controller configured for controlling a flow of the fluid from the fluid container to the fluid distributor. The flow controller includes an adjustable valve and is configured for operating in a first mode of operation that supplies the fluid to the fluid distributor at a first volumetric flow rate; a second mode of operation that supplies the fluid to the fluid distributor at a second volumetric flow rate that is lower than the first volumetric flow rate; and a third mode of operation that supplies the fluid to the fluid distributor at a third volumetric flow rate that is lower than the second volumetric flow rate.

FILTER ASSEMBLY AND FLOOR CLEANER
20230053356 · 2023-02-23 ·

The present disclosure provides a floor cleaner that includes a replaceable component, such as a filter. The floor cleaner has a detection mechanism comprising a magnet on the replaceable component and a Hall Effect sensor positioned to detect the permanent magnet when the replaceable component is correctly installed on the floor cleaner. Operation of one or more electrically-powered components of the floor cleaner is prevented when the permanent magnet is not detected by the Hall Effect sensor.

Extraction with temporary suction interrupt
11497370 · 2022-11-15 · ·

An extractor includes a fluid recovery system including a suction nozzle, a recovery tank assembly, and a suction source having an inlet fluidly connected to the recovery tank assembly and the suction nozzle through an air conduit and adapted to draw liquid through the suction nozzle and deposit the liquid in the recovery tank assembly. The extractor includes a body provided with the air conduit for movement between a first position wherein suction is unreduced and a second position wherein suction is reduced. The extractor includes a fluid delivery system including a solution supply tank assembly, a fluid distributor, and a conduit for depositing fluid onto a surface. The extractor includes a hydraulic connector operably coupled to the body and adapted to move the body between the first and second positions.
