Cleaning head for use in a floor cleaning machine
First Claim
1. A cleaning head for use with a floor cleaning machine to perform a cleaning operation on the floor, the cleaning head comprising:
- a first cleaning tool configured for rotation about a first horizontal axis and having an exterior cleaning surface configured to engage the floor during floor cleaning operations;
a second cleaning tool configured for rotation about a second horizontal axis and having an exterior cleaning surface configured to engage the surface during floor cleaning operations;
at least one motor configured to respectively drive the rotation of the first and second cleaning tools about the first and second horizontal axes; and
a cleaning tool support configured to support the first and second cleaning tools for movement of the first and second horizontal axes relative to each other in a plane that is transverse to the first and second horizontal axes, and to maintain the first and second cleaning tools in engagement with each other during cleaning operations as they wear.

Abstract
A cleaning head for use with a floor cleaning machine comprises first and second cleaning tools, at least one motor and a cleaning tool support. The at least one motor is configured to respectively drive rotation of the first and second cleaning tools about first and second horizontal axes. The first and second cleaning tools each have an exterior cleaning surface configured to engage the floor during floor cleaning operations. The cleaning tool support is configured to support the first and second cleaning tools for movement of the first and second horizontal axes relative to each other in a plane that is transverse to the first and second horizontal axes. Another embodiment of the invention is directed to a floor cleaning machine that includes embodiments of the cleaning head.
