At that price we have a more efficient vacuum that our Dyson broom 2011, although cheaper, quieter hair, thought better ergonomic level (it does not have to use the index to press a trigger!), The triangular head is edging pieces or furniture in practice, effective park position and the surprising life: the aspiration of 90m is made 13-15 minutes (no big dirt, just dust) and the battery is not "lose" load: probably it holds well the announced 45min.
In short: this vacuum broom surprise us pleasantly, broom keeps its promises. Draining sofabed quite simple, clearly it must be done without waiting for either "too full" to avoid small suction losses.
