not great suction.  also, the unit sits on a charging plate.  it's wobbly.  i would have preferred a wall attachment so it doesn't take up counter space.  
i drop birdseed all over the floor and it took forever to suck it up with this vac.  i should have just swept.  it would have been much fast.  this is good for hair and dog fluff, nook and corner cleaning.  now i need to figure out where to put it - it stands straight up, so it's too tall to sit on my counter under the cabinets.  this design is lame.
