Floor cleaner scrub head having a movable disc scrub member
First Claim
1. A scrub head configured for attachment to a frame of a mobile floor cleaner, the scrub head comprising:
- a main support;
a first disc scrub member attached to the main support and rotatable about a first vertical axis, wherein a portion of the main support overhangs the first disc scrub member;
a movable support pivotally connected to the main support and having first and second positions;
a movable disc scrub member rotatable about a second vertical axis and connected to the movable support, the movable disc scrub member configured to move relative to the first disc scrub member along first and second orthogonal axes of a horizontal plane, which is transverse to the first and second vertical axes, between first and second positions respectively corresponding to the first and second positions of the movable support; and
a locking mechanism configured to lock the movable support in the first position and fix the relative positions of the first disc scrub member and the movable disc scrub member.

Abstract
A scrub head includes a first disc scrub member, a movable support having first and second positions, and a movable disc scrub member. The first disc scrub member is rotatable about a first vertical axis. The movable disc scrub member is rotatable about a second vertical axis and is connected to the movable support. The movable disc scrub member is configured to move relative to the first disc scrub member along first and second orthogonal axes of a horizontal plane, which is transverse to the first and second vertical axes, between first and second positions respectively corresponding to the first and second positions of the movable support.
