I bought it for work but checked it at home and now it's out of the house. We have been vacuuming with a 5ah battery for the second month without recharging.

Pros
Simple, lightweight, comfortable. It takes up a minimum of space, and a 5Ah battery was enough for 4 months of regular cleaning.
Some pros:
Compact, easy to get into hard to reach places. Plus, the lack of wires, one of the main reasons for which it was bought.
Different cons:
Not really a minus, there is not enough fixation of the power button. Must be held during use.
