This is a cordless hand held vacuum cleaner.
It recharges on a mount that can be screwed to the wall.
Please note that the batteries really need to be replaced or serviced. Currently the cleaner only operates for less than a minute.
The cells are NiMH 1.2v per cell. There are 3 cells giving a total of 3.6v.
The current batteries are Huanyu NiMH sc1500.
Please only ask for this cleaner if you are capable of servicing the battery pack. A couple of the photos should give an idea of what is involved.
