Too thick. This deprives small bots of the ability to clean in a straight line as the water pickup area is different between each cleaning stroke. When swiping to the left, the right side picks up more water, then when moving forward, backward, it's a bit heavy on one side, and then to the right, it doesn't fully make it like disposable cleaning pads. If they were thinner, the water would be forced to spread more evenly, as is the case with disposable pads. Does not stay clean and misses large areas due to imbalance. Not recommended except for dry cleaning.
