Hi, and maybe what seems a strange question but have never had 1 before!
I received above item as a gift and as question suggests, it plugs into car lighter to use. However, I am not clear (as have either used domestic hoover & extension from home/caravan-3 pin plug-to clean car or the type at garages) whether this should be used with engine turned on/running or with key in ignition and set to turn 1 or 2?
If I use without turning engine on I fear this may drain the battery and therefore train of thought is that I should use when engine running. For technical information purposes, if it assists:
Product Name: Car Vacuum Cleaner
Input Current: 8A
Input Voltage: DC-12v
Power: 106W
Power Cord Length: 14.76ft
Vacuum Degree: ≥4.5KPa
Finally, I cannot envisage using the vac for anymore than 20 mins max (as this is what it has taken on previous occasions & car does not get absolutely filthy in any event). Prior to using any vac, have always used firm brush to agitate and brush all 'dirt' and detritis down to car mats, then brushed or hoovered these indoors using home hoover.
Many thanks for replies on what might seem a simple query!
