Abstract: A mopping unit comprises a mop bucket combined with a wringer having two squeeze rollers mounted at the top of the bucket. An operating mechanism for the squeeze rollers includes a toggle linkage comprising two toggle links which are directly interconnected at a toggle pivot. When the two toggle links are aligned, the toggle pivot is substantially coplanar with the separate rotational axes of the two squeeze rollers one of which is moved, to the operative wringing position, by the operating mechanism on depression of a foot pedal.

Abstract: Cleaning equipment comprises a container, such as a bucket usable for mopping, from which cleaning liquid is taken and to which that liquid is returned after it has been used for dirt removal. The container is provided with a dirt trap comprising a dirt-receiving element of mat or pad-like form which is positioned in the container to receive dirt settling under gravity from the contained liquid. The dirt which settles out collects in, or alternatively passes through so as to be trapped below, the element or mat. The form and structure of the element is such that disturbance of the liquid in the container cannot wash the collected dirt back out into the main body of liquid from, or through, the element to any significant extent.

Abstract: A collapsible mop pad holder comprises two opposite end leaves pivotally mounted on a central support which is connectible to a handle, and a catch operative to latch the end leaves in an erected condition. The catch comprises a latch member pivotally mounted on one of the leaves and depressible from a latching position, in which it engages the other leaf to latch both leaves together and thus maintains the erected condition of the holder, to an unlatching position in which it is retained until the mop pad holder is collapsed. The arrangement is such that on re-erection of the mop pad holder the latch member automatically re-assumes the latching position.

Abstract: A sweep mop pad holder comprises a central support section with a handle mounting on its upper side, and two end sections. The end sections are pivotally mounted on the central section and they are engageable with a mop pad which is thereby securely held on the pad holder, with the end sections retained in a generally aligned erected position. One end section is extended inwardly beyond the handle mounting so that whereas with the holder collapsed both end sections can hand down freely for wringing out of the mop pad, the handle can be so positioned relatively to the support section that it engages the inward extension of the one section and can be used to support that end section whereby the mop can be re-erected by engagement of the collapsed mop with the floor by an operative holding the handle.

Abstract: A mopping unit comprises a bucket, a wringer with two squeeze rollers mounted at the top of the bucket, and an operating mechanism to produce relative closing movement of the rollers. The operating mechanism comprises a foot pedal mounted at a lower level on the bucket and a toggle operating linkage operative on depression of the pedal to produce the relative closing movement of the rollers. At the end of the closing movement of the rollers the toggle linkage goes over-center to lock the rollers at a predetermined spacing in an operative mop-wringing position.
