For one 12 gallon shop vac that covers both home messes and car cleanup, our pick is the CRAFTSMAN CMXEVBE17594. It is a mainstream 12 gallon wet/dry unit with a widely stocked accessory range, which in daily use matters more than any single number on the box. Choose it when you want a do everything vac living in a garage or utility room and you accept that a 12 gallon body is bulkier to carry out to the driveway than a small portable. If noise is your main concern, the Shop-Vac 5430098 Ultra Quiet is the one we would reach for instead.
The short answer: which 12 gallon shop vac for home and car
All three vacs here share the same 12 gallon tank, so the real question is which one fits the way you work. A 12 gallon drum is generous for a home and a car: you can pull up sawdust and drywall grit in the garage, switch to wet pickup after a spill, and still have room before you empty it. The trade off is size. Twelve gallons is heavier and taller than a compact 4 to 6 gallon vac, so it is less convenient to lift into a trunk or carry up stairs. If most of your work happens in one spot and you roll the vac to the car in the same garage, that trade off is easy to live with. Our pick balances tank room, a familiar brand, and an accessory range you can actually find in stock.
CRAFTSMAN CMXEVBE17594 12 Gallon Wet Dry Shop Vacuum
Our pick for most people: a 12 gallon wet/dry vac from a mainstream brand, with a 6.0 peak horsepower listing claim and attachments that are easy to source. A sensible default for a garage that doubles as home and car cleanup duty.

CRAFTSMAN CMXEVBE17594 (our pick). This is the one we would buy first if you have no strong preference. The CRAFTSMAN 12 gallon wet/dry vac pairs a full 12 gallon drum with a 6.0 peak horsepower rating listed by the maker, and CRAFTSMAN accessories, hoses, and filters are stocked almost everywhere, so replacing a worn part later is simple. It stands out as the safe all rounder for a home and car setup.
Shop-Vac 5761311 (the classic). If you prefer the original Shop-Vac name, the Shop-Vac 5761311 12 gallon covers the same ground with a 6 peak horsepower listing claim and the same 12 gallon capacity. We would choose it when you already own Shop-Vac attachments or filters and want to keep one accessory ecosystem rather than mixing brands.
Shop-Vac 5430098 Ultra Quiet (the quiet one). If the noise of a shop vac drives you out of the garage, the Shop-Vac 5430098 Ultra Quiet is built around lower sound as its selling point, with a 5.5 peak horsepower listing claim. The slightly lower peak figure is a reasonable trade for being able to run it without clearing the room. We would reach for it when you vacuum the car in the evening or share walls with neighbors.
What actually matters, and what to ignore
Tank gallons versus portability. This is the decision the whole category turns on. A bigger tank means fewer trips to empty it, which is nice for a workshop. For a car, though, you rarely fill even a small tank, and a 12 gallon body is more to move around. Buy the 12 gallon size because you want home jobs handled, not because the car needs it. If a portable vac that lives in the trunk is what you actually want, a 12 gallon unit is the wrong tool and a smaller one would serve you better.
Wet and dry pickup. All three are wet/dry vacuums, so they handle water, damp debris, and dry dust once you fit the right filter or remove the cartridge for wet jobs. Follow the maker instructions on which filter to use for wet versus dry, because running the wrong setup can clog a filter or let fine dust blow back into the room.
Peak horsepower and airflow. Treat the peak horsepower numbers here, 6, 6.0, and 5.5, as listing claims rather than measured performance. Peak horsepower is recorded for an instant at motor stall, not during normal running, so a higher figure does not reliably mean a stronger vac in use. What you actually feel is airflow combined with sealed suction, and those depend as much on the hose diameter and a clean filter as on the motor label. We will not quote airflow figures the makers do not publish consistently. The practical takeaway is that all three have enough pull for home and car work, so do not let a small peak horsepower gap decide your choice.
Hose and attachments. The hose and nozzles matter more for car cleaning than the motor. A longer hose lets you reach across a car without dragging the drum, and a crevice tool and a soft brush handle vents, seats, and footwells. Check that the model you pick includes the attachments you need, and favor a brand whose extra tools are easy to buy, which is part of why our pick leans on CRAFTSMAN availability.
Filter. The filter is the part you live with. A cartridge filter for dry dust and a foam sleeve for wet pickup are the usual pair, and keeping a spare on hand saves a stalled job. A clogged filter kills suction faster than any horsepower difference, so plan to rinse or replace it on the schedule the maker lists.
What to ignore. Ignore peak horsepower bragging between models that are a half point apart, ignore drum color and styling, and ignore any suggestion that a bigger tank cleans better. Capacity only changes how often you empty it.
How the three compare
On paper these three are closer than the model numbers suggest. The CRAFTSMAN and the Shop-Vac 5761311 share a 12 gallon tank and a 6 peak horsepower listing claim, so the choice between them comes down to which brand accessory range you want to live in and what is in stock when you order. The Ultra Quiet model trades a slightly lower 5.5 peak horsepower claim for quieter running, which is a genuine quality of life difference in a home garage even though it is not a raw power upgrade.
For a home and car role specifically, our ranking is simple. The CRAFTSMAN is the default because of its balance and easy to find parts. The Shop-Vac 5761311 is the pick when you are already in the Shop-Vac accessory world. The Ultra Quiet is the pick when noise, not power, is the thing that would stop you from using the vac at all. None of the three is a mistake for this job; they are variations on the same sensible 12 gallon idea.
Our honest verdict
If you want one answer, buy the CRAFTSMAN CMXEVBE17594. It gives you a full 12 gallon tank for home jobs, enough reach and suction for car cleanup, and an accessory and filter supply you will not struggle to restock. Step to the Ultra Quiet Shop-Vac if quieter running is worth a touch less rated power, or stay with the Shop-Vac 5761311 if you are already invested in Shop-Vac tools. Whichever you choose, set it up with the right filter for the job, keep the hose and cartridge clean, and the 12 gallon size will serve a home and car well for years.
A quick note on safe use: Note to follow the maker's instructions, wear appropriate protection, and check local codes/permits where relevant.
