Need a car vacuum for cleaning out my new shed build - any recommendations?

Hey everyone, I'm in the middle of building a 12x16 shed and the interior is full of sawdust and wood shavings from cutting the framing. I need a car vacuum to clean it out, but I want something that can handle fine dust and maybe even small screws/nails. I've seen some cordless ones, but I'm worried about battery life. Should I get a wet/dry vac or a dedicated car vacuum? My budget is around $100. Any suggestions?

For that kind of job, I'd honestly go with a small wet/dry vac over a car vacuum. Car vacuums are great for quick touch-ups, but for a shed full of sawdust, you need something with more suction and a bigger capacity. I've got a 2.5-gallon Shop-Vac that I use for my workshop and car - it's portable enough, and it handles sawdust like a champ. Plus, you can get a crevice tool for tight spaces. Look for one with a HEPA filter if you want to catch the fine stuff. You can find a decent one for around $60.

I gotta say, DeWalt makes a great cordless vacuum that's perfect for this. I use the DeWalt 20V MAX* cordless wet/dry vac and it's a beast. It's compact, but has strong suction and can run on the same batteries as my other DeWalt tools, so I never worry about battery life - I just swap in a fresh one. It's a bit over your budget, but it's worth it if you're already invested in the 20V system. Plus, it's got a blower function to blow out the sawdust before you vacuum it up - easy cleanup!

Careful with the cordless ones - they can be top-heavy and tip over, and the battery might not last as long as you think when you're vacuuming fine dust for an hour. I'm all about precision, so I'd go with a corded 5-gallon wet/dry vac with a cartridge filter. It'll have consistent suction, no worrying about batteries, and you can get one with a dust collection bag that makes emptying less messy. I've got a Ridgid 5HP that I've had for years and it still sucks like new. Just make sure to use a filter that's rated for fine dust, not just the cheap foam one.

Thanks for the input, everyone! I think I'm leaning toward a corded wet/dry vac after hearing the concerns about battery life and tip-overs. I'll look for a 5-gallon one with a good filter and a crevice tool. I'll probably get the Shop-Vac or Ridgid that you guys mentioned. Appreciate the help!
