I have no carpet, all hardwoods and linoleum.

With 11 cats, I gave up trying, and bought a 6 gal wet vac, Lowe's had them on sale for $24.99 a while back. I use the floor brush from my prior vac, as the work horse brush has no bristles on it and would mar the hardwood.

Oh the suction! It is getting EVERYTHING up, thank goodness. True, I have to fish the catnip mice out of the grub when I empty it, but that is minor. I am very pleased.

It is not as noisy as the old wet/dry vac we had, pleasant surprise!
