Many of the homes I clean in have extremely expensive flooring in the entries and between carpeted areas.
As any professional steam cleaning service should, I have an aversion to doing any damage to floors and don’t even allow solution to drip on flooring.
I go to great lengths to apply paper, tape, runners…pretty much any tool I have to mitigate any risk of damage to flooring.
The following video is a good example of a job that required a careful setup.
Very few companies take the same precautions I do , by the way but it should be a standard in our industry.
