I am a window cleaner going up to 2 stories in commercial and residential. I am curious about the purified water units that clean without squeegee or wiping. You must be able to make a unit yourself cheaper than 7000. Which Aquaclean sells. Also which is better Tucker or the Aqua clean poles? Thanks in advance and if you need supplies I get them at Dallas Window Cleaning Supplies. They have been very helpful with new products. Thanks in advance! [2022]
