I recently used this window vac. from Karcher and I was happy with the result, it has an integrated battery (kind of) but not difficult to change. I would like to have it as a proper cordless tool working with Metabo CAS 12V or DeWALT 12V batteries. It is a bit big and from the photos you feel it would be small till you get it in your hand, that is why I think flat batteries like DeWALT and Metabo 12V batteries would be better than Bosch and Milwaukee 12V round batteries to keep it more stable. In the second photo you can see the size properly.
