What statement about carpet and floor care equipment is TRUE?

High-speed rotary floor machines are indeed not suited for use on carpets. These machines are primarily intended for hard floor surfaces, such as tile, vinyl, and sealed wood, where they can effectively strip, polish, or buff the flooring. The high speed and power of these machines could cause damage to carpet fibers, leading to fraying or overall wear.

Additionally, other equipment specifically designed for carpets, like carpet extractors or vacuum cleaners, would be more appropriate for maintaining carpeted surfaces. It's crucial to choose the right machine for the right type of flooring to ensure both effectiveness in cleaning and preservation of the materials.
