First off , I 'll try to be as objective as I can with the admit limited experience with vacuum cleaner -lrb- probably around the same as anyone who do not work in the vacuum or cleaning industry -rrb- . this be my first bagless cleaner , I have use a Eureka and a Hoover for a combined 12-13 year before switch to this . the vacuum cleaner have great suction , but I have learn several thing that potential buyer should probably be aware of : 1 -rrb- probably the most minor gripe be a lack of a `` brush switch '' that switch off the main brush when you be use the hose , which I have on my previous -lrb- admittedly more expensive -rrb- Hoover . the vacuum be design so that the front pop up when its in the upright position , but I find that the brush still rub against my not-very-high carpet . 2 -rrb- the hose be nowhere near long enough if you want to vacuum stair , I have to move the vacuum every couple step to keep the thing from tip over . and I do not know why a stiff plastic piece be at the end of the hose , it make vacuum in tight space a hassle -lrb- I get that it be for reach , but would not it be nice to have it as a removable piece so you have the option ? -rrb- 3 -rrb- be prepare to buy a extra filter , the helix design be not the best , as it rely on spin the air to fling out particle of dust , which settle into the cup , the problem be , once a little dust start to clog the little slit and filter up , the suction weaken , which reduce the suction a little bit allow more dirt to get suck into the filter , which reduce the suction a little bit more , and so forth . a cyclone be slightly better because the swirl of air travels upwards , allow more dirt particle to settle what wind up happen be the filter quickly clog up and it lose suction quite quickly . my place be not very big , maybe around 1500 sq ft , and I vacuum once every 2-4 week , and I find I have to wash the filter nearly every time . 4 -rrb- lastly , and most importantly , let you filter dry overnight after you wash it , and run you vacuum for a few minute after install it to make sure its dry . I make the mistake of not run it -lrb- though I do let the filter dry overnight -rrb- and the next time I use it , it smell like rotten fish . I have to take the whole thing apart and clean everything to get rid of the smell . would have be nice if they have a sort of catchment to trap any water that might have drip . other than that , I find the vacuum to be acceptable , though have to wash the filter so often be a hassle and make a royal mess . I be not sure if all bagless vacuum require so much cleaning and emptying , but next time I 'll probably go back to a bagged one , or try a cyclonic vacuum make sure its less of a hassle to clean first .
