I love cordless vacuum cleaner -- very convenient . I like Black & Decker , BUT -- this be the 1952 FIAT \/ RENAULT of cordless vacuum cleaner . do it work ? yes , barely & at what trouble . if the designer bother to give this to they wife for a try-out before production , they would all be divorce . whoever design this contraption should have he pay firmly fix to the sale of this sow . whoever approve this & the tooling cost have better start look for a new career . get a enemy ? give they one for a gift , or better yet , send the vacuum to the Taliban - they 'll surrender after the 1st use ! positive : 1 . good charge shoe . 2 . great battery power -lrb- and noise -rrb- but minimum suction . 3 . compact folding for storage -lrb- motor home -rrb- . -- that be it . negative : 1 . very uncomfortable handle - bad design \/ angle . 2 . weigh a ton because all the weight be 1\/2 way up , include the motor , so it constantly pull down on you forearm & shoulder instead of be down on the head at the floor where you would barely feel it . 3 . this also cause the head to not have enough weight to hold the brush in proper contact for maximum performance on any carpet or rug . 4 . this also make the head hard \/ awkward to control . 5 . very difficult to glide & have no tilt \/ steer action - sub-miniature wheel be of no use on carpet . 6 . have a crazy back of head ` foot ' extension that get catch on everything when you pull the vacuum back & forth & flip the head up ! 7 . empty the vacuum be mind-boggling , one slight slip try to hold this monster & it be all on the floor or all you filter \/ cover part be in the garbage . 8 . return be non-existent . they can not sell they so they do not want they either . the cure : HOOVER platinum linx -- the Rolls-Royce ` State-of-the-Art ' of the genre . you 'll fall down & thank God . cost more BUT you get more than you money 's worth , instead of a insult .
