A typical home vacuum cleaner has the following specs
Input watts (Electrical) = 1000W
Suction = 80 inch H2O
Output watts = 100 air watts
where as a 12V car vacuum cleaner has
Input watts (Electrical) = 100W
Suction = unspecified (10 inch guesswork)
output watts = unspecified (10 air watts guesswork)
car vac manufacturers don't publish output air watts or suction so let's say we guess it to the above figures.
The fact is even at such low suctions car vacs still do sell and people use them.
But what I don't understand is given that there is such a huge difference in specs how does a car vac even pull in dirt, is 10 inch of water capable to generate enough suction power, or are car vacs actually generating higher suctions than my initial guess which I don't see how they could given that the input power is so low?
