Floor cleaner

Abstract

A floor cleaner is disclosed including a first cleaning roller that is operatively positioned on a cleaning head to engage the surface to be cleaned. A second cleaning roller is operatively positioned on the cleaning head, parallel to the first cleaning roller. The second cleaning roller is movable between a first position engaging the surface to be cleaned and a second position spaced from the surface to be cleaned. A carriage assembly is coupled to the second cleaning roller. The carriage assembly is configured to move the second cleaning roller between the first position and the second position. A drive assembly is operatively connected to and configured to rotate at least one of the first cleaning roller and the second cleaning roller. An actuator is operable to move the carriage assembly from the first position to the second position.

What is claimed is: 
     
         1 . A floor cleaner comprising:
 a body;   a cleaning head pivotally connected to the body and configured for movement across a surface to be cleaned, the cleaning head including a suction inlet;   a first cleaning roller operatively positioned on the cleaning head to engage the surface to be cleaned;   a second cleaning roller operatively positioned on the cleaning head, parallel to the first cleaning roller, movable between a first position engaging the surface to be cleaned and a second position spaced from the surface to be cleaned;   a carriage assembly coupled to the second cleaning roller, the carriage assembly configured to move the second cleaning roller between the first position and the second position;   a drive assembly operatively connected to and configured to rotate at least one of the first cleaning roller and the second cleaning roller;   a suction source in fluid communication with the suction inlet;   an actuator operable to move the carriage assembly from the first position to the second position.   
     
     
         2 . The floor cleaner of  claim 1 , wherein the second cleaning roller is pivotable about the first cleaning roller to move from the first position to the second position. 
     
     
         3 . The floor cleaner of  claim 1 , wherein the actuator is a cable having a proximal end connected to the carriage assembly and a distal end connected to a user interface, the user interface configured to pull the cable moving the second cleaning roller from the first position to the second position. 
     
     
         4 . The floor cleaner of  claim 3 , wherein the second cleaning roller is retained in the second position spaced from the surface by the cable. 
     
     
         5 . The floor cleaner of  claim 1 , further comprising a spring applying an upward force on the carriage assembly or the second roller toward the second position. 
     
     
         6 . The floor cleaner of  claim 1 , further comprising a spring applying a downward force on the carriage assembly or the second roller toward the first position. 
     
     
         7 . The floor cleaner of  claim 1 , wherein the actuator is a drive motor assembly operatively connected to the carriage assembly configured to move the second roller from the first position to the second position. 
     
     
         8 . The floor cleaner of  claim 7 , wherein the second cleaning roller is retained in the second position spaced from the surface by the force of the motor. 
     
     
         9 . The floor cleaner of  claim 1 , wherein the first cleaning roller is a soft microfiber roller and the second cleaning roller includes a plurality of tufted bristles. 
     
     
         10 . The floor cleaner of  claim 1 , wherein the second cleaning roller is movable relative to the first cleaning roller.
