hope to see both of yall post any questions or ideas.
one thing i like about you & your forum Mark is that you don't try to push on others that the Challenger and Outsolve can do EVERYTHING. while i am sure they both clean tile & grout very nicely, you aren't afraid to post other products that work as well. similar with your posts mentioning other products that work well besides Outsolve. shows you care about us, your clients, and putting them ahead of trying to make a sale.
thanx for the professionalism and honesty, it's quite refreshing to see from a supplier!
