Scrubber head anti-vibration mounting

A floor scrubbing machine comprising:

• a support structure and lower supporting wheels mounted on said support structure and defining a horizontal plane of support;
• powered scrub brushes beneath said support structure;
• a brush carriage connecting said scrub brushes to said support structure whereby said scrub brushes are vertically movable beneath said support structure;
• a power actuator between said support structure and said vertically movable carriage for raising or lowering said conditioning elements;
• and
• a frictional motion dampener between said carriage and said support structure to dampen vibration of said carriage during operation of said scrub brushes.

• powered scrub brushes beneath said support structure;
• a brush carriage connecting said scrub brushes to said support structure;
• a frictional motion dampener between said brush carriage and said support structure to dampen vibration of said carriage, comprising at least one fixed member, a pair of friction members on said brush carriage spaced from each other and astraddle said at least one fixed member, and a pair of biasing members biasing said pair of friction members against said fixed member.
