Does your wand whistle when you set it down? Here is the answer. I hope this helps the puzzle somewhat. When a cleaning wand is not down on the carpet is there a whistling noise coming from it? Does this drive you crazy, and annoy your customers? The whistle is coming from the center of the vacuum orifice. If you look at it, you will see that the center of the vacuum orifice is narrower than the edges. This constricting is having 2 effects. One is limiting the amount of air going through it, minimizing the air flow, which makes the cleaning and drying efforts less than the wand maker intended, and leaving the carpet wetter than it could be if the opening was wider, allowing more air, with it's load of water going through it. The second effect is on your eardrums, and your customer's eardrums, with the whistling noise. To correct this problem, simply insert a screwdriver, or similar object into center of the vacuum opening, and bend the lips apart. You will notice immediately a diminishing of the whistling, and you can readily see the difference in the gap at the center. When the wand lips are sufficiently open, the whistling noise will be gone completely. The same process will work on stair tools, and furniture tools that whistle. |
