Where these two actually differ

  • We flag Volatile organic compounds (VOCs) from vinyl, adhesive, and coating, Phthalates or other plasticizers in PVC and adhesive and Adhesive degradation and leaching over time on the Daltile 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 Daltile.
  • The Daltile is Vinyl composition tile (VCT) with adhesive backing and protective coating where the Rug Doctor is Aqueous cleaning solution, surfactants, water, which is most of the difference in these two grades.
  • The gap is 45 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 Daltile 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 →
