Where these two actually differ

  • We flag Undisclosed stain treatment composition (likely fluorochemicals), Formaldehyde and volatile organic compounds (VOC) off-gassing, Flame retardant additives in backing or treatment and Microparticle and dust accumulation from fiber shedding and treatment degradation on the Mohawk and not on the Rug Doctor.
  • We flag Surfactant skin and eye irritation and Residue buildup on carpet fibers on the Rug Doctor and not on the Mohawk.
  • The Mohawk is Nylon carpet with stain/soil treatment (proprietary) where the Rug Doctor is Aqueous cleaning solution, surfactants, water, which is most of the difference in these two grades.
  • The gap is 40 points, wide enough that this is not a close call, and the Rug Doctor is the one to buy.
  • We are less certain about the Mohawk grade, at 35% confidence against 72%, because it discloses less.

Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
