Abstract

A floor scrubber with a floor scrubber head having a backing plate to which a pad is secured with the pad adapted to being placed in contact with a surface to be cleaned. The scrubber head includes a motor support to which a motor is mounted with the backing plate being secured to the motor support, with the motor configured to move the backing plate and pad when cleaning a surface. The scrubber head further includes a cover member having an opening through which the motor extends, with the cover member further including a pair of wheels with an outer perimeter of the wheels partially extending beyond a periphery of the cover member.

Claims

1. A floor scrubber, said floor scrubber comprising:

wheels for movably supporting said floor scrubber;

a base assembly; and

a scrubber head;

said scrubber head comprising a backing plate to which a pad is secured with said pad adapted to being placed in contact with a surface to be cleaned, said scrubber head further comprising a motor support to which a motor is mounted with said backing plate being secured to said motor support, and wherein said motor is configured to move said backing plate and said pad when cleaning a surface, and wherein said scrubber head further comprises a cover member, said cover member including an opening through which said motor extends, said cover member further including a pair of wheels with an outer perimeter of said wheels partially extending beyond a periphery of said cover member.

2. The floor scrubber of claim 1, wherein said backing plate is secured to said motor support by a plurality of vibration isolator mounts.

3. The floor scrubber of claim 2, wherein said motor support is secured to said cover member by a plurality of vibration isolator mounts.

4. The floor scrubber of claim 3, wherein the durometer of said vibration isolator mounts securing said motor support to said cover member is higher than the durometer of said vibration isolator mounts securing said backing plate to said motor support.

5. The floor scrubber of claim 1, wherein said cover member includes a top member and a generally vertically oriented front member depending from said top member, wherein said opening is formed in said top member and wherein said front member is positioned adjacent a front edge of said pad, and wherein said scrubber head includes an applicator for discharging cleaning fluid, said applicator being disposed under said cover member adjacent said front member.

6. The floor scrubber of claim 5, wherein said cover member further includes a pair of generally vertically oriented side members, and wherein said cover member includes a pair of wheels with an outer perimeter of said wheels partially extending beyond planes defined by said side members and said front member.

7. The floor scrubber of claim 1, wherein said scrubber head further includes a pair of mounting flanges extending from said cover member with said opening disposed between said mounting flanges, and wherein said floor scrubber further includes a pair of arms with said arms being releasably connectable to said scrubber head.

8. A scrubber head for a floor scrubber, said scrubber head comprising:

a backing plate to which a pad is secured with said pad adapted to being placed in contact with a surface to be cleaned;

a motor support to which a motor is mounted with said backing plate being secured to said motor support, and wherein said motor is configured to move said backing plate and said pad when cleaning a surface; and

a cover member, said cover member being secured to said motor support and including an opening through which said motor extends, with said cover member further including a pair of wheels with an outer perimeter of said wheels partially extending beyond a periphery of said cover member.

9. The scrubber head of claim 8, wherein said backing plate is secured to said motor support by a plurality of vibration isolator mounts.

10. The scrubber head of claim 9, wherein said motor support is secured to said cover member by a plurality of vibration isolator mounts.

11. The scrubber head of claim 10, wherein the durometer of said vibration isolator mounts securing said motor support to said cover member is higher than the durometer of said vibration isolator mounts securing said backing plate to said motor support.

12. The scrubber head of claim 11, wherein said vibration isolator mounts securing said base plate to said motor support comprise lower vibration isolator mounts, and wherein said vibration isolator mounts securing said motor support to said cover member comprise upper vibration isolator mounts, and wherein said upper vibration isolator mounts and said vibration isolator mounts are cylindrical, with said upper vibration isolator mounts being shorter and having a larger diameter than said lower vibration isolator mounts.

13. The scrubber head of claim 8, wherein said cover member includes a top member and a generally vertically oriented front member depending from said top member, wherein said opening is formed in said top member and wherein said front member is positioned adjacent to and extends parallel with a front edge of said pad, and further including an applicator for discharging cleaning fluid, said applicator being disposed under said cover member adjacent said front member.

14. The scrubber head of claim 13, wherein said applicator comprises a conduit, and wherein said conduit includes a plurality of orifices aimed at said pad.

15. The scrubber head of claim 13, wherein said cover member further includes a pair of generally vertically oriented side members, and wherein said cover member includes a pair of wheels with an outer perimeter of said wheels partially extending beyond planes defined by said side members and said front member.

16. The scrubber head of claim 8, wherein said scrubber head further includes a mounting flange extending from said cover member, said mounting flange configured to enable said scrubber head to be connected with a floor scrubber.

17. The scrubber head of claim 16, wherein said scrubber head includes a pair of mounting flanges extending from said cover member, and wherein said opening in said cover member is disposed between said mounting flanges.

18. A scrubber head for a floor scrubber, said scrubber head comprising:

a backing plate to which a pad is secured with said pad adapted to being placed in contact with a surface to be cleaned;

a motor support to which a motor is mounted with said backing plate being secured to said motor support by a plurality of lower vibration isolator mounts, and wherein said motor is configured to move said backing plate and said pad when cleaning a surface; and

a cover member secured to said motor support by a plurality of upper vibration isolator mounts, said cover member includes a top member having an opening through which said motor extends, wherein said top member extends approximately the entire width and length of said pad whereby said pad is substantially enclosed by said cover member.

19. The scrubber head of claim 18, wherein said cover member includes a generally vertically oriented front member depending from said top member, wherein said front member is positioned adjacent to and extends parallel with a front edge of said pad, and further including an applicator for discharging cleaning fluid, said applicator being disposed under said cover member adjacent said front member.

20. The scrubber head of claim 19, wherein said cover member includes a pair of wheels with an outer perimeter of said wheels partially extending beyond a periphery of said cover member.

21. The scrubber head of claim 20, wherein said cover member further includes a pair of generally vertically oriented side members, and wherein the outer perimeter of said wheels partially extends beyond planes defined by said side members and said front member.

22. The scrubber head of claim 18, further including a pair of mounting flanges extending from said top member, and wherein said opening in said top member is disposed between said mounting flanges.
