Why has the SweeperVac lost suction?

"The SweeperVac usually loses suction once the dirt bin is full, so all you have to do is empty the dirt bin. However, the filter could also be damaged, in which case you need to replace the filter.

If neither of those are the case, then it is possible that battery has low charge, in which case recharge it.

If none of those work, then maybe the hose is clogged. Remove the dirt bin, and there is an opening to the hose, which should allow you to reach inside with some sort of tool and remove any debris."
