I have a Animal Dyson and when I move it be steal !!! I have be look at different vacuum and read review on what be out there . I regard the review on Amazon as invaluable and can sometimes make or break my decision to purchase something . I also subscribe to Consumer Reports and find that the Miele have the highest rating of any vacuum . if you check Miele 's website , it claim they be at the top of good housekeeping 's list also . I be hesitant to spend over $ 400 for something online without the option of testing it . so , I go to the local sew and vac store to test drive it . First of all the twist have great maneuverability when vacuum around corner , under chair , etc. . also , the vacuum motor be separate from the brush motor which not only pick up well , but make the vacuum easier to push . for someone with a disability that can not push a heavy vacuum , this be a great bonus ! the switch to turn the brush off and on be at the top of the handle next to the power button which be excellent for those of we who hate to -lrb- or can not -rrb- bend to the floor to switch from carpet to bare floor . also , just below the handle be setting for deep pile , low pile , smooth and curtain . the curtain setting be awesome ! there be enough suction to clean they without try to suck they into the hose . I have also be able to vacuum chair , couch and pillow with ease . no fight the suction there ! the hose on the Miele be very flexible and allow for easy use of the hose and on board attachment . the hose on the Dyson would have so much suction go through that I could not extend the hose and the Dyson fall on my foot and leg many time while I be fight the suction . the Miele have anti-tip technology which I have put to the test . it actually do tip once , but I have pull the hose it be full length , so it do not surprise I . I be at least 6 foot away , so it do not fall on I . other reviewer indicate the hose pull out of the vacuum . I do not have any trouble with that during the store demonstration or on the Miele twist I buy from the sew and vac store . possibly they get a lemon ? from the Miele website , here be the description for all 4 standard style upright : suction control via rotary dial with 4 variable power setting 1,200-watt , miele-made Vortex Motor 4,800 r.p.m. brush roller motor 2-motor system , with separate control for electrobrush Motor protection indicator Tools\/Accessories include electrobrush with independent motor 4 , versatile accessory low-profile electrobrush pass under low-clearance furnishings cord 39-foot electrical cord additional feature impressive 54-foot cleaning radius patent swivel-neck for maximum maneuverability Automatic carpet height adjustment 360  front castor wheel 12-foot , integrate , flexible hose anti-tipping device for enhance stability when use include accessory reinforce , ergonomic handle for both operation and transport\/carrying 7-Year Motor Warranty & 7-Year Casing Warranty The difference be : twist have air clean filter and no headlight jazz have hepa filter and headlight Salsa have hepa filter and headlight Cat & Dog have air clean filter , headlight and turbobrush attachment -lrb- the salesperson demonstrate that a replacement hepa filter can be put into the twist or cat & dog -rrb- I hate to call the twist the basic model , but it be the least expensive of the four . I feel like I get a good deal and excellent vacuum for the price and see no need to pay a extra $ 150 or more just for headlight . I do not test any of the Miele canister vacuum , but the salesperson say canister vac be better for home that be mostly hardwood floor . I could go on and on about how wonderful I think the twist be ! I be not aware , but another reviewer say you could lose you warranty if purchase online . I would say that if you do not have a dealer nearby and must buy online , get it from Miele directly , that way you warranty will not be void . sorry Amazon .
