Walk Behind Floor Cleaning Apparatus With Floating Tank

Abstract

A self-propelled walk behind floor cleaning apparatus includes a frame. A plurality of floor engaging wheels support the frame above a floor and a brush assembly fixed to the frame agitates a fluid on the floor. A floating tank is supported by the frame.

1 . A self-propelled walk behind floor cleaning apparatus comprising:
 a frame;   a plurality of floor engaging wheels supporting said frame above a floor;   a brush assembly fixed to said frame and agitating a fluid on the floor; and   a floating tank supported by said frame.   
   
   
       2 . The floor cleaning apparatus as in  claim 1 , in which one of said tank and said frame includes a peg receptacle receiving a peg extending from the other of said tank and said frame, said peg receptacle having a length and being open along at least a portion of said length allowing said tank to float relative to said frame. 
   
   
       3 . The floor cleaning apparatus as in  claim 2 , in which said tank includes a peg receptacle formed therein, and said peg receptacle opens downwardly. 
   
   
       4 . The floor cleaning apparatus as in  claim 1 , in which said tank is pivotally supported on said frame. 
   
   
       5 . The floor cleaning apparatus as in  claim 4 , in which a detachable restrainer restricts pivotal movement of said tank. 
   
   
       6 . The floor cleaning apparatus as in  claim 1 , including a resilient latch urging said tank toward said frame. 
   
   
       7 . The floor cleaning apparatus as in  claim 1 , in which said tank is partitioned into at least two volumes, one of said volumes holding unused cleaning solution and the other of said volumes holding recovered cleaning solution. 
   
   
       8 . The floor cleaning apparatus as in  claim 1 , including a squeegee assembly fixed to a rear end of said frame, said squeegee assembly recovering solution from said tank. 
   
   
       9 . The floor cleaning apparatus as in  claim 1 , in which said brush assembly includes at least one motor driven brush. 
   
   
       10 . The floor cleaning apparatus as in  claim 1 , including handlebar fixed relative to said tank for grasping by a user walking behind and operating said apparatus. 
   
   
       11 . A self-propelled walk behind floor cleaning apparatus comprising:
 a frame having a rear end and a front end;   a plurality of floor engaging wheels supporting said frame above a floor;   a floating tank supported by said frame;   a fluid dispenser in fluid communication with said tank and dispensing a fluid from said tank onto a floor;   a brush assembly fixed to said frame rearwardly of said fluid dispenser and agitating the fluid on the floor; and   a squeegee assembly fixed to a said frame rearwardly of said brush assembly and recovering the fluid from the floor.   
   
   
       12 . The floor cleaning apparatus as in  claim 11  in which one of said tank and said frame includes a peg receptacle receiving a peg extending from the other of said tank and said frame, said peg receptacle having a length and being open along at least a portion of said length allowing said tank to float relative to said frame. 
   
   
       13 . The floor cleaning apparatus as in  claim 12 , in which tank includes a peg receptacle formed therein, and said peg receptacle opens downwardly. 
   
   
       14 . The floor cleaning apparatus as in  claim 11 , in which said tank is pivotally supported on said frame. 
   
   
       15 . The floor cleaning apparatus as in  claim 14 , in which a detachable restrainer restricts pivotal movement of said tank. 
   
   
       16 . The floor cleaning apparatus as in  claim 11 , including a resilient latch urging said tank toward said frame. 
   
   
       17 . The floor cleaning apparatus as in  claim 11 , in which said tank is partitioned into at least two volumes one of said volumes holding unused cleaning solution and the other of said volumes holding recovered cleaning solution. 
   
   
       18 . The floor cleaning apparatus as in  claim 11 , including handlebar fixed relative to said tank for grasping by a user walking behind and operating said apparatus.
