  • maintaining is understood as treating the floor surface in a manner, which is non-destructive to such an extent as to render it suitable for use on a daily basis.
  • the term “maintaining” is not to be understood as limited to use on a daily basis.
  • the invention is based on the understanding that while filtering the cleaning liquid reduces or eliminates the effect of cleaning agents, the use of the diamond fiber pad, in its turn, reduces or eliminates the need for cleaning agents in the first place, thus enabling the use of filtering and recirculation of the cleaning liquid without any major loss of effect.
  • Purification techniques which may be used include, but are not limited to, ultraviolet light, filtration, cyclonic separation, water softening, reverse osmosis, ultrafiltration, deionization, heating, electrodeionization and powdered activated carbon treatment.
  • the cleaning liquid may be contained in a cleaning liquid container, from which it may be drawn to be applied onto the floor surface.
  • the purified cleaning liquid may be returned to the cleaning liquid container.
