I ordered these stair treads so my dog wouldn't slip when going up the beautiful lacquered wooden staircase, and also to protect the stairs from scratches from her paws.  They work very well and vacuum very nicely.  I ordered the dark brown.  If I had it to do over again I would have ordered the tan so it wouldn't show the specks of dust and grass as much as the dark brown does - but they do vacuum well and look great afterwards.
