I think this vacuum work fabulous on my carpet . however most of my home be hardwood floor . I could still feel crumb , grit under my foot after vacuum . it do not get debris in corner nor near a wall . my cheap $ 90 vacuum have a height adjustment . I write the vendor -lrb- morequalitylessmoney -rrb- and ask if there be a way to adjust the height . after 2 email and no response I send the vacuum back .
