Description

Box and wet cleaning assembly Technical Field The present invention relates to a cartridge attachable to a wet cleaning apparatus, such as a wet floor cleaning apparatus. The invention also relates to a wet cleaning assembly comprising such a cartridge and a wet cleaning device. Background Mop and bucket are commonly used to clean floors. However, more and more wet cleaning devices are shown replacing such mops and buckets. Manually operated and electrically powered wet cleaning devices have been proposed. Such wet cleaning devices typically comprise a cleaning liquid reservoir, i.e. a reservoir containing a cleaning liquid to be delivered to the surface to be cleaned. In some cases, the reservoir is filled with a pre-mixed solution of a surface treatment agent (e.g., a detergent) and water. When the reservoir is empty, more pre-mixed solution may be refilled. There are wet cleaning devices that have a reservoir that can be filled with water by a user, and the user can add their own surface treatment agent to the water of the reservoir. In the latter case, difficulties are encountered in controlling the ratio between water and surface treatment agent to produce a cleaning solution having a suitable concentration of surface treatment agent. The capacity of the reservoir may be limited compared to the old water bucket. This may mean that a surface treatment agent formulated for addition to such a water bucket (which may contain more volume of water for diluting the surface treatment agent) is not suitable for addition to the reservoir of a wet cleaning device, because the concentration of such a surface treatment agent is too high. The use of cleaning solutions with too high a concentration of surface treatment agent may interfere with/damage wet cleaning equipment or result in sub-optimal cleaning results. This problem can be alleviated by the user being instructed to first add a limited amount of surface treatment agent to a dosing cup having a defined volume and then transfer the amount of surface treatment agent to the reservoir. However, this additional step is often inconvenient for the user. This becomes even more inconvenient when the concentration of the surface treatment agent is relatively high, as the user has to dose a relatively small amount of surface treatment agent into the reservoir very accurately, which increases the burden. AU 2020 100,206a4 discloses a sweeper that includes a fluid delivery system for providing a cleaning fluid to a floor surface. US11,219,347 B2 discloses an autonomous floor cleaner or floor cleaning robot comprising an autonomously movable housing and a drive system for autonomously moving the autonomously movable housing over a surface to be cleaned based on input from a controller. The brush chamber, debris container and supply tank are formed as a unitary assembly that is removable from the autonomously movable housing. EP 2 636 353 A2 discloses a surface cleaning apparatus, such as a steam mop or a fluid delivery mop, which includes a handle and a foot coupled to the handle for movement along a surface to be cleaned. Disclosure of Invention The invention is defined by the claims. According to an example of a first aspect of the present invention there is provided a cartridge attachable to a wet cleaning apparatus for dosing a surface treatment agent from the cartridge, the cartridge comprising a chamber for containing the surface treatment agent, an interface portion for interfacing with the wet cleaning apparatus, the interface portion comprising a coupling portion for coupling the cartridge to a complementary coupling portion of the wet cleaning apparatus during attachment of the cartridge, and a cover assembly for covering at least a portion of the interface portion prior to attachment of the cartridge, wherein the cover assembly comprises a further complementary coupling portion configured to be detachably coupled to the coupling portion such that when the cartridge is not attached to the wet cleaning apparatus, the cover assembly covers at least a portion of the interface portion, the removal of the further complementary coupling portion from the coupling portion enabling attachment of the cartridge to the wet cleaning apparatus via the coupling portion. Since at least a portion of the interface portion of the cartridge that interfaces with the wet cleaning apparatus is covered, the cover assembly may prevent leakage of the surface treatment agent before the cartridge is attached to the wet cleaning apparatus. Otherwise, such leakage may occur, for example, due to pressure and/or temperature variations during transport of the cartridge. The cover assembly may also help provide tamper protection and/or protection of at least a portion of the interface portion during storage and shipping of the cartridge. Since the coupling portion is detachably coupled to the other complementary coupling portion of the cover assembly and may also be coupled to the complementary
