Kirby Power Tester IV Used as a tool during a Kirby Sales Demonstration Kirby Power Tester IVtool is used during a demonstration to show off the suction power of the Kirby. It is almost impossible to lift off this tester tool off of Kirby. However it can be easily removed from other competitive vacuums. The Power Tester IV will convince the prospect because they will actually feel the resistance of the Kirby while trying to pull the tester tool off. The point of the tool is to show off the lifting ability of the Kirby. A carpet can not be cleaned just by the vibration, it needs to be lifted. The higher it is lifted, the more the nap is opened and the dirt is removed more efficiently. This tool will make that point. In an unlikely scenario where the tester can NOT be removed from the competitive vacuum, a salesman can state that there is no way to judge this type of comparison on a demo. Only weights with pulley in a test laboratory can be used to make this determination. Instructions for using the power tester: Power drive must be in NEUTRAL. Stand vacuum upside down, resting the handle grip on the floor. Place Power Tester IV Over rug plate on uprights and power heads, with brushes turning. Instruct your prospect to LIFT slowly and evenly, STRAIGHT UP to feel the resistance on their vacuum, and then on the Kirby. A foul is called for using two hands, sliding off, or using a finger to break the seal by lifting the edge.
