As the only drawback I find that you can only attach the pipe when the vacuum cleaner 'lies', although it can be wonderfully maintained and it would be much less space if you could make the pipe firmly in this position.
Unfortunately, our vacuum cleaner today, gone after 8 months break. Only this morning I had emptied it and then sucked the normal apartment. I still had to make it a second time and suck beside fallen potting soil - as he made short (2-3Sekunden) a strange noise as if he were clogged, went out, smoked and stank.
That does not detract from my rating, however, Amazon has immediately sent me a return label via e-mail and get a new promised - so here also, great customer service! (And that Something is broken, can happen always)
