I live in a nearly 100 year old house that seems to be seeping dust out of the pores. My answer to the house cleanliness question is a 5 gallon vacuum with plenty of extension cord, dusting brush, clean filter and this attachment. I wish I had found this many years ago. This brush is better than any of the fancy vacuums I've tried over the years, works well with my shop vacuum and cleans all my hard floors really well, right down to the edge of the baseboard. It cleans the joints between the floorboards. Makes my life easier.
