On occupied residential, it took some practice to get proficient and quicker and better using it...
and I had to quit being stubborn and not adjust the height on a padded carpet, or removing the weight....sometimes I'm still stubborn though an run it in the commercial height setting....
But, I use the Zipper in homes a lot because people are always asking "how soon before it will be dry?"
and the Zipper not only cleans well in so many situations.....
It out dries anything I have used!
So, for some, using in on occupied residential can be a challenge....for me....I just am stubborn enough to want to use it everywhere I can
And just find it works great for me and my son in law
But Marty has some legitimate points as well....
