RubbermaidCommercial Products Cleaning Power Scrubber Microfiber Refill Kit, Stainless Steel, Red and Gray, 15 Pack

Does Rubbermaid (or any other manufacturer) make a head for this with brass bristles? I want to use it on metal (like garden tools or grill grates).

The bornku electric spin scrubber seems versatile for cleaning tasks. anyone with experience using it for larger areas?

Is this really worth buying?...better than using a good bristle brush and scrubbing floor tile myself?

did your rubbermaid reveal power scubber slow down when using?
