great suction , pivot be a plus , and switching from brush to no-brush be fantastic . Cordless be the biggest selling point . I have no complaint about the battery life . empty the dust bin be a nightmare . the dust bin be inseparable from the vacuum , so I have to fold the vacuum in half , lift the hatch , and dump the dust out over a garbage can . since I have a cat , I often have to get my hand in the bin to get the hair off the filter . all-in-all , empty the dust bin be terrible .
