Why do they ship them with the DIRT still in 'em-would LOWER the shipping cost-and what about the peice of pink string or thread wrapped around the rollerbrush?Sellers on EBAY are sure LAZY!Another reason I don't use them.Besides $150 is TOO MUCH to pay for that machine full of dust and string twined in the roller brush-look at local vac dealers or yard sales.The $9.99 bid is more reasonable.
