Disclosed is a cleaning brush for cleaning toilet bowls and the like. The brush has a permanent handle and replaceable/disposable brush heads that are flushable after each cleaning. The brush is a stack of sheets of water-dissolvable and/or agitation-dissolvable material. The sheets can be attached together at an end by pressure bonding or by a water-soluble adhesive and formed with bristles at an opposite end. The wand provides a remote system for clamping and unclamping the brush head.

The invention claimed is: 1. A brush head that on an overall basis is water-degradable, the brush head being suitable to be held by a cleaning device, wherein the brush head comprises a plurality of layers of a water-degradable material positioned on top of each other to form a stack of such layers

The invention claimed is: 1. A brush head that on an overall basis is water-degradable, the brush head being suitable to be held by a cleaning device, wherein the brush head comprises a plurality of layers of a water-degradable material positioned on top of each other to form a stack of such layers, wherein at least two of the layers are formed from a sheet of the water-degradable material that has been folded back upon itself, and wherein the head is configured such that a first end of the stack is held together by the brush head and an opposed end of the stack can spread out between at least some of the layers of the stack; wherein layers of the stack at the bottom and top of the stack are not impregnated with a surfactant while a plurality of layers of the stack between the top and bottom layers are impregnated with a surfactant. 2. The brush head of claim 1, wherein at least five external side surfaces of the brush are free of surfactant. 3. The brush head of claim 1, wherein at least one of the layers of the brush head comprises at least two plies of the water-degradable material. 4. The brush head of claim 1, wherein the water-degradable material is a nonwoven fibrous web of cellulosic material that is hydroentangled. 5. The brush head of claim 1, wherein at least one layer of the water-degradable material is abrasive. 6. The brush head of claim 5, wherein the abrasive layer of water-degradable material is apertured. 7. A brush head that on an overall basis is water-degradable, the brush head being suitable to be held by a cleaning device, wherein the brush head comprises a plurality of layers of a water-degradable material positioned on top of each other to form a stack of such layers, wherein at least two of the layers are formed from a sheet of the water-degradable material that has been folded back upon itself, and wherein the head is configured such that a first end of the stack is held together by the brush head and an opposed end of the stack can spread out between at least some of the layers of the stack; wherein water-dissolvable attachment means has been applied to the brush head adjacent the first end of the stack to hold that end of the stack together, while still allowing at least a part of the opposed end of the stack to spread out between layers; and wherein the first end of said brush head is formed with an axially extending notch. 8. The brush head of claim 7, wherein the axially extending notch tapers axially from an outer portion of the brush head towards a bristle portion of the brush head. 9. The brush head of claim 7, stored in a sealed pouch having a circumferential pouch tear line. 10. The brush head of claim 9, wherein the pouch does not contain more than one such brush head. 11. A wand for holding a brush head, the wand comprising: a handle having an internal axial cavity, a lower opening communicating with the cavity, and a radial opening; an actuator having a projection extending through the radial opening, a connecting rod linked to the projection which is mounted in the handle cavity, and a jaw linked to the rod which extends out the handle lower opening; wherein the wand is constructed and arranged such that a first movement of the projection will move the jaw to a first position suitable to release a brush head if the brush head has been inserted in the jaw, and a second movement of the projection will move the jaw to a second position suitable to clamp a brush head if a brush head has been inserted in the jaw; wherein the handle has teeth that extend radially into the cavity and the connecting rod has radially outwardly extending teeth. 12. The wand of claim 11, where the handle teeth and rod teeth can interfit to inhibit at least one form of axial relative movement there between. 13. The wand of claim 12, wherein the handle teeth and rod teeth are angled such that they more readily can inhibit relative axial movement there between in a first direction as compared to relative axial movement there between in a direction opposed to the first direction. 14. The wand of claim 13, wherein a spring is positioned along the connecting rod to radially outwardly bias the projection. 15. The wand of claim 11, wherein the rod has a portion with a cross-shaped cross sectional appearance. 16. The wand of claim 11, wherein at least one outer contact ear is formed on a jaw. 17. The wand of claim 11, wherein the wand is for holding a toilet brush head and a portion of the handle adjacent a jaw is curved. 18. The wand of claim 11, wherein a brush head has been inserted into a jaw. 19. The wand of claim 11, wherein a portion of the rod extends through that curved portion. 20. The wand of claim 11, wherein the handle has a lower drain hole. 21. A wand for holding a brush head, the wand comprising: a handle having an internal axial cavity, a lower opening communicating with the cavity, and a radial opening; an actuator having a projection extending through the radial opening, a connecting rod linked to the projection which is mounted in the handle cavity, and two jaws linked to the rod which extend out the handle lower opening; wherein the wand is constructed and arranged such that a first movement of the projection will move both of the jaws to a first position suitable to release a brush head if the brush head has been inserted between the jaws, and a second movement of the projection will move both of the jaws to a second position suitable to clamp a brush head if a brush head has been inserted in the jaw; wherein the wand has been attached to a separately formed extension, the extension having a hanger hole. 22. A wand for holding a brush head, the wand comprising: a handle having an internal axial cavity, a lower opening communicating with the cavity, and a radial opening; an actuator having a projection extending through the radial opening, a connecting rod linked to the projection which is mounted in the handle cavity, and two jaws linked to the rod which extend out the handle lower opening; wherein the wand is constructed and arranged such that a first movement of the projection will move both of the jaws to a first position suitable to release a brush head if the brush head has been inserted between the jaws, and a second movement of the projection will move both of the jaws to a second position suitable to clamp a brush head if a brush head has been inserted in the jaw; wherein a jaw has an axially extending tongue projection suitable to interfit with a brush head having an axial notch. 23. The wand of claim 22, wherein the tongue projection is a triangular projection.
