1. A floor scrubber comprising:

  • a frame with an open bottom and two parallel sidewalls;

    an upwardly open receptacle for a treatment liquid located between said sidewalls in said frame;

    a set of guide rollers with horizontal axes journaled in said sidewalls;

    an endless belt of liquid-absorbing material passing around said guide rollers, said belt having a lower run projecting downwardly from said open bottom and an upper run dipping into said receptacle;

    a pair of arms mounted in said receptacle for swinging about a pivotal axis parallel to those of said guide rollers, said arms terminating in a pair of downwardly open journal bearings;

    a further roller disposed in said receptacle above said upper run with an axle lodged in said journal bearings; and

    spring means engaging said arms for urging said further roller downwardly against said upper run to tension said belt, said arms being upwardly swingable against the force of said spring means to a sufficient extent to enable dislodgment of said axle from said journal bearings and withdrawal of said further roller from said receptacle to facilitate removal of said belt from said guide rollers around one of said sidewalls.
