Bosch vac for rm399
18V battery and charger sold separately

A bagged type works pretty well even for a sub-rm300 panasonic.
Bagless one well you need to clean the filter out after awhile.

I mainly use wired ones for better suction, sub 300 type
For home use Pana cocolo bagged type works well for me.. just that you need to dig and shake out the dust from the bag if cheapo to replace bag each use.. I recon like a dozen times at least
For rough use like vacuuming sand from newly VP apartment, a Karcher WD1 bagless shop vac is pretty powerful (big tong capacity)
