The filter is suitable but I haven't used it yet so I'm not sure about its effectiveness. I've only tried the replacement side brush and it works great. There was a fairly loud squeak when first used. I think it's because the replacement brush is longer than the original brush. But I just folded the brush more vertically and the annoying noise stopped. If you look at the original brush that came with the yeedi K781+ (vacuum/mop and self-cleaning station), the bristles of the brush stand upright, almost like a tulip, rather than flat. Simply squeeze the plastic handles holding the stubble to reshape it. Soaking the brush in very warm water can help soften the plastic and make it easier to reshape. I will update this review if another replacement doesn't work.
