i am still amazed that you have 3 levels to vacuum! you muct got a big crib.
my mum used to make me vacuum the stairs i hated that, it took ages.
those handheld vacuums are great for the CAR they pick up most things, its quite strong, the only disadvantage its gets full very quick, i reckon you should get one. but not the cheapest one just incase, always get the middle range price.
