apart from standard positive of this vacuum like number of extension , follow be some positive which I think be really unique : 1 . power . vacuum cleaner be indeed powerful as mention by other in they review . 2 . Mode control knob . this knob , at the base of vacuum that help you in control the mode , be useful indeed . you can easily clean hard floor at low power whereas you need more power if you be clean carpet . and control be give to you , which be always good . 3 . Cable length . I love the length of cable this vacuum cleaner come with . I be able to clean two room from a single socket in my living room . it be always frustrate to keep on plug in vacuum after every 5 min . this long cable ensure I do not have to do it every now and then . 4 . light bulb . a light source give on this vacuum which move with vacuum be a well think feature . it do not only help with light at dark place , but also give you a idea of how close or far you the vacuum 's edge be from the wall . it help in avoid bang into wall while cleaning . negative : 1 . it be little heavier -lrb- bulky -rrb- . if you be willing to compromise on feature and power and if you have a backache problem , I would not recommend you this vacuum . it be not very bulky and if you be fit enough , you will not even feel the weight . this warning be for people who be already suffer from a backache . 2 . better manual . not that vacuum be very hard to assemble , but more picture in manual would give I more confidence when I assemble it .
