A retainer for removably attaching a sheet to a cleaning device. The retainer has at least one cantilevered finger extending inwardly from the periphery of a cavity towards the inside of that cavity. Behind the retainer is a flexible barrier, at least partially covering the back of the cavity. The barrier prevents the user's finger from going too far into the cavity and becoming pinched, and allows the thickness of the device to which the sheet is attached to be reduced compared to a device having a conventional sheet retainer. The barrier may provide visual and/or tactile barrier cues to a user, qualitatively signaling the user which direction is proper for insertion of the sheet into the retainer and quantitatively signally the user how far the sheet should be inserted into the retainer. Strands and/or a membrane panel which are elastic or inelastic may be used for the barrier.

1. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device, said pivotable sole plate being pivotally attached to a housing of said floor cleaning device, said pivotable sole plate having a first face and a second face opposed thereto, said retainer and sole plate of the floor cleaning device comprising: at least one finger, said finger being juxtaposed with said first face of said pivotable sole plate of said floor cleaning device and being cantilevered from a proximal end, said finger being deformable in a first direction to receive a cleaning sheet on said pivotable sole plate; anda flexible barrier juxtaposed with said at least one finger and being juxtaposed with said second face of said pivotable sole plate of said floor cleaning device and being exposed when a cleaning sheet is not attached to said pivotable sole plate, said flexible barrier deforming relative to said rigid pivotable sole plate upon contact with said finger, when said finger is deflected to contact said barrier. 2. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 1 wherein said finger is cantilevered from the perimeter of a cavity, said cavity having a closed perimeter defining a center, said retainer comprising plural fingers, each said finger being cantilevered from a proximal end juxtaposed with said perimeter to a respective distal end, said distal ends being juxtaposed with said center of said retainer. 3. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 2 wherein said barrier comprises a membrane. 4. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 3 wherein said barrier comprises a resilient membrane. 5. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 4 wherein said fingers are generally planar in a first plane and said membrane is generally planar in a second plane, said first plane and said second plane being generally mutually parallel, said fingers and said membrane being spaced apart 4 mm to 8 mm. 6. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 5 wherein said membrane completely covers said cavity. 7. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 3 wherein said resilient membrane is taut. 8. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 3 further comprising a sheet engaged therein. 9. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 1 wherein said barrier and said at least one finger contact each other in a free position without said finger being deflected. 10. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device, said pivotable sole plate being pivotally attached to a housing of said floor cleaning device, said pivotable sole plate having a first face and a second face opposed thereto, and said retainer and sole plate of the floor cleaning device comprising: at least one cantilevered finger and a barrier being spaced apart and defining a cavity having no intervening component therebetween, said barrier being juxtaposed with one said face of said pivotable sole plate and thereby exposed,said finger being resiliently deflectable in a first direction towards said barrier to attach a cleaning sheet to said first face of said pivotable sole plate of said floor cleaning device, whereby upon contact with said finger said barrier deflects relative to said rigid pivotable sole plate in response thereto, thereby providing a signal to a user attaching a cleaning sheet to said floor cleaning device. 11. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 10 having a center and further comprising a plurality of fingers cantilevered from respective proximal ends to respective distal ends, each of said distal ends of said plurality of fingers deflecting said barrier upon contact therewith. 12. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 11 wherein said barrier comprises flexible strands with discrete spaces therebetween. 13. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 12 wherein said barrier is flaccid. 14. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 12 wherein said barrier is taut or pre-tensioned. 15. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 11 wherein at least some of said fingers are tapered to a point at said respective distal ends, said points of said fingers contacting said membrane in response to insertion force applied by a user. 16. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 15 wherein at least some of said fingers converge to a common point. 17. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 10 wherein said barrier comprises nonwoven material. 18. A retainer in combination with a rigid, pivotable sole plate of a floor cleaning device according to claim 10 wherein said barrier comprises a membrane. 19. A retainer, in combination with a rigid, pivotable sole plate of a floor cleaning device, said pivotable sole plate being pivotally attached to a housing of said floor cleaning device, said pivotable sole plate having a first face and a second face opposed thereto, and said retainer and sole plate of the floor cleaning device comprising: a flexible barrier;at least one cantilevered finger being bendable in a first direction towards said barrier to thereby attach a cleaning sheet to said first face of said pivotable sole plate of said floor cleaning device, said barrier being urged away from said rigid pivotable sole plate by said bending of said finger.
