I do a lot of research before buy this vacuum . I finally narrow my selection down to two machine and go with the Eureka because it be a trust name and I have a canister vacuum by they that I adore . this purchase be such a mistake . at the same time that I be buy my vacuum , my mother be buy one as well . we both need a upright vacuum that could handle pet hair and carpeting . I be completely oppose to bagless vac and she be open to whatever would get the job do . she end up purchase the Shark Navigator after watch they infomercial for a hour . when she shipment arrive I put it together for she and be actually pretty impressed . I tend to associate infomercial product with useless pasta drainer and clumsy at-home gym equipment . but this vacuum be NICE . it be lightweight and clean they old carpeting really well . but I feel confident in my Eureka and be excite that it would be arrive any day . so the Eureka arrive and it be beautiful . bright red and shiny ! just look at the box get I excited for all the feature . a spotlight ! Pet attachment ! brush ! Extension nozzle !!! I could not wait . I begin put the machine together and immediately notice how heavy it be . I do not let that bother I because I purchase this vacuum strictly for my upstairs . I plan on leave it upstairs and keep my canister vacuum downstairs for the bare floor . if I do not have to lug it up and down the stair all the time , who care if it be a bit on the cumbersome side ? well , I do ! once I finally deposit all of the attachment in they proper spot and drag the thing upstairs I decide to take it for a whirl . do the carpet look clean ? yes . BUT , this be brand new carpet only a month old , so it be not the best test . but it definitely pick up all the pet hair and my looooong hair strand . but I could not even enjoy the clean carpet because I be in a full body sweat after vacuum two small bedroom -lrb- 14 x 11 -rrb- . literally . a full body sweat . this vacuum be so heavy to push and pull ... I have never experience anything like it . I should explain that I be in pretty decent shape . I run and lift weight regularly . and I be in my 20 's . my 5 minute vacuum test drive be exhaust from the weight of the machine and the extra bend down I have to do every few seconds because all of the attachment and extra hose piece keep fall off . as I be start to put the vacuum away , I start inspect the piece and discover that the hose have several puncture mark on it ! these mark must have occur during shipping and\/or packaging . upon further inspection I notice that the hose feel incredibly fragile for belong to such a massively heavy piece of equipment . well , those hole be the nail in the proverbial coffin . Heavy be one thing ... damage be another . so I be return the Boss . and , yes , I already buy the Shark . I be put it together tomorrow . P.S. I love Amazon . they make the return incredibly easy . a otherwise infuriating experience be always mitigate by they superior customer service .
