purchase the Miele twist after much research and consumer review . love the machine . let I say that I be a vacuum fanatic and use my vacuum at least every other day , and I mean at least -lrb- I have 3 kid , 2 dog , and a dirty backyard -rrb- . immediately the power of the vacuum be note and even though it be a bit heavy on the pull-back , it be BECAUSE of the 2-motor design and so I will take power with weight any day . the carpet look the best I have see it in at least a couple of year -lrb- animal stain aside -rrb- and I think I be almost addict to run it just to see the carpet plush , full and hear the dirt cyle through the hose -lrb- before the kid come home \* wink \* -rrb- . I worry about how it would handle my 15-staircase , but the hose extend to at least 12 stair quite beautifully and it be not difficult to balance the vacuum while I clean the last upper three . another thing I be curious about be the length of the cord , but again - I have be please to note that I can vacuum all of my downstairs from one convientently place outlet . speak of downstairs , I adore how easy it be to shift from carpet to vinyl with just the flip of the switch and it do such a great job cleaning too . but , if you note I give it 4-stars vs 5 and you may be wonder why . well , here be my quirk with the machine . while I love how long the cord be - I do not like how it can not seem to stay wind up on the machine , it fall off loop-by-loop as I move around the room . I plan to amend this annoyance by get a velcro loop and make my own sort of contraption to keep it on the machine . I also find annoyance with a particular situation , that may be only related to I -lrb- and my own amazingly charge personality \* wink \* -rrb- , but it will shock I if the machine get too close to my leg while run it . I learn with research that the machine use a electrobrush -lrb- see -lrb- ... -rrb- -rrb- and this may be the cause of my experience . if I remember to keep it away and not pull it so close to my heart , as I want since I love it so , then it be fine . \* smile \* now , on the principle of sandwich , I must leave you with another loved aspect of this machine . I love the manuverability of the machine . it be like the Dyson ball , in effect , but the power and allergen control of a Miele . I can bring it low and it do not alter how it work , and I can easily move it between and around my furniture . all in all - I be in love . the cord do not stay on the machine very well and I get a small shock every now and then , but other than that - I adore the machine . for the price , it be a real bargain .
