I bought a varied package. I only use blue. Once you learn how to jiggle them and fit them into the tricky Braava 240, they work great. He's very picky about installing the pads correctly, otherwise he'll beep and refuse to work. But that seems to be an issue with Braava, not these pads. After use, I clean them in the kitchen sink with a dab of washing-up liquid and a brush, and then immediately use them again in the next room. Since I never use the white and orange pads, I can't say anything about them and would prefer to only buy the blue ones.
