I have try many different vacuum . this be the only one that really get my house CLEAN , which my allergy certainly appreciate . 1 -rrb- it pull the fine dust out of the base of my carpet -- now it `` squeek '' lightly when I walk on it -lrb- previously , the dust lubricate its motion against the pad -rrb- . 2 -rrb- because it be bagless , I can empty it right away and the nasty stuff do not get a chance to fester and smell bad the next time I use the vacuum . I really love use a vacuum that do not make the air dusty or smelly ! I do make a point of clean it out thoroughly -lrb- knock off the dust outside the house -- I only wash filter occasionally . -rrb- and I wipe off exterior dust with a microfiber `` miracle '' dust cloth . I do this cleaning after every use so it be nice , clean , and ready to go for next time . the first time I use it , there be so much dirt in my carpet I need to empty it after each room ! usually , though , it 'll do a big chunk of the house before the dust bin be full . I do not let the dustbin overfill , because then the dust get pull deeper into the machine . this be the second Bissell I have own . the first one 's rotate brush burn up after two year , which disappoint I . but it be still worth it for the price !
