no portable vac will give the power of a real car wash vac(meaning a central unit and plumbed to each station consisting of a 220v or 440v huge turbine vacuum unit. those things can suck some stuff up for sure lol, can suck a quarter up from about 6 inches or so away. just go with a rigid or shop vac, will work great for vacuuming carpets, i have some standard nozzles, some micro nozzles and a couple bissel nozzels i use for extraction, works great with the correct technique. those micro nozzles are a life saver when detailing, can just vaccuum alot of the dust out of cracks and crevices and hard to reach areas. i love my micro nozzles.
