US 2026/0108124 A1 · CARTRIDGE AND WET CLEANING ASSEMBLY

Abstract

Provided is a cartridge (100) attachable to a wet cleaning apparatus, in particular a wet floor cleaning apparatus. The wet cleaning apparatus has a volume displacement device (102) for dosing surface treating agent from the cartridge when the cartridge is attached to the wet cleaning apparatus. The cartridge comprises a chamber (106) for containing surface treating agent. The cartridge also has an interfacial portion (107) for interfacing with the volume displacement device during attachment of the cartridge to define a dosing assembly (108). At least one way valve (116, 120) is configured to enable fluid to exit the chamber and/or the dosing assembly by operation of the volume displacement device, and restrict passage of the surface treating agent therethrough prior to attachment of the cartridge. Further provided a cleaning assembly comprising a cartridge and a wet cleaning apparatus.

Dependent claims

A cartridge attachable to a wet cleaning apparatus, the wet cleaning apparatus having a volume displacement device for dosing surface treating agent from the cartridge, the cartridge comprising:

a chamber for containing surface treating agent;
an interfacial portion for interfacing with the volume displacement device to define a dosing assembly during attachment of the cartridge;
and
at least one one-way valve configured to restrict passage of the surface treating agent therethrough prior to attachment of the cartridge to the wet cleaning apparatus, wherein the at least one one-way valve is closeable by fluid movement in a first direction, and is openable by fluid movement in a second direction opposite the first direction so that the at least one one-way valve enables fluid to pass therethrough to exit the chamber or to exit the chamber and the dosing assembly by operation of the volume displacement device.
