The overspray is the result of the spray hitting the back of the
glide and running off the end. I used to think it was due to the glide raising the wand lips up too high, but once I saw that putting extenders on actually made it WORSE I realized we all are wrong about the cause.
The next wand I buy will have adjustible jets.
I have a fear of employees creating furniture dye problems by running the wand along the side of a dresser or something. The overspray collects right at the base of the furniture and all the drying passes you can do won't get it out. The next time you clean there, if you are asked to move the furniture, you'll see the stain line.
Brady and I have learned to stay a bit clear of the furniture with the side of the wand glide while cleaning to prevent that, but an employee is a different story.
