I use a higher density sponge that is made for taking fur and hair off fabric. I don't know what it's called - I found it at my local hardware store. It "rolls" the fur up into easy to grab clumps.

Grooming is definitely a help. If you have long-haired babies, consider getting them semi-shaved every so often.

I've been thinking of getting a Swiffer myself. Sweeping and damp mopping all in one.

For dusting - a magnetic duster.

And I got rid of my clumping litter because of all the dust. There is one - in Canada anyway - called Maxx Cat with a urine deodorizer, and NO DUST. The urine evaporates fairly well; and I wouldn't go back to the dusty clumping stuff for love or money! Not sure it's good for the cats either.

Good luck!
