The Simonis X-1, admittedly over-priced, does, in fact, work as advertised on Simonis and similarly woven pool table cloths. There are cloths that have a weave that has more nap than the Simonis and these will develop pill pilings if the X-1 is used on them.
Also, some people tend not to use the X-1 as directed. They push down too hard on the cloth. You're supposed to slide the X-1 lightly to make the static action work properly and this way will also prevent chalk dust from being pushed into the pockets.
