@@cleaningphd6453 I agree. A Professional should invest in the best tools. And, after viewing numerous videos, I see how both the pure water and extension water pole is the most effective and efficient tools a professional should use. I think you? said it best, start out with soap and squeegee, once you have core customers, purchase these. Thanks for responding. I wish you the best for your future.
