Thank goodness to the reviewer who posted the attached photo because I couldn't find that info anywhere. I've only used it to clean tile floors hoping that steam cleaning would remove the solution, but it just pushed the water out and then barely sucked it back in. There is a huge puddle on the floor. It's not the nozzles, but the Bissell ProHeat2x Revolution PetPro is not suitable for cleaning hard floors. Great for carpets and spot cleaning of fabric furniture, but that's about it.
