we recently purchase the twist when a 3 year-old Bissell fail . we do considerable research online & consider various review in the process . because we have a Labrador Retriever with pet-hair issue , we target Dyson & Miele as the best probable solution . we go to a local dealer & test both head-to-head . the Miele pick up test debris that the Dyson do not , so we choose the twist model price well-below Dyson 's comparable model . we could not be more pleased with the selection . it pick up everything & change a bag may be a add expense , but it be so much easier & neater than dump a dust cannister . the Miele make the carpet look & `` feel '' much cleaner & more like-new , & do a far-superior job to previous vacuum on bare wood floor . the only challenge be to figure out the easiest way to clean stair , but once master , it be not a problem . you will definitely pay more for the Miele , but it be a superior performer & with separate motor for the beater-brush & the suction , it be pretty much guarantee to last far longer than other less-expensive variety . give the Miele a test & you 'll be convince as to its quality .
