Wasted $200 on a cheap dust collector. Don't do it.

Bought a little 1hp Harbor Freight dust collector last year thinking it would save me money. After 6 months of swapping bags every week and still having fine dust everywhere, I trashed it. The thing couldn't pull through a 10 foot hose without clogging. I ended up getting a used 2hp unit from a guy retiring for $150 and it actually works. Take it from me, save up for a real system or buy used. Anyone else get burned by undersized shop gear like this?

Is it really that big of a deal though? I mean yeah a cheap dust collector isn't great but you can still make it work if you know what you're doing. I've seen guys run a 1hp unit with a good cyclone and it does fine for most hobby stuff. Sounds like you just got a bad one or your expectations were too high for what $200 buys you.

Nah I gotta push back on that. That 1hp unit at Harbor Freight is borderline useless for anything beyond a single small tool like a sander or maybe a miter saw. I tried running mine with a 4 inch hose and a short run to my planer and it still clogged up after 20 minutes. The real issue is those cheap units don't have enough static pressure to pull fine dust out of the air, they just recirculate it back into the room. That $200 waste taught me that you're basically paying for a loud fan that collects nothing meaningful. You can't slap a cyclone on a 1hp motor and expect it to magically work better because the motor just doesn't have the power to overcome that additional resistance. I'd rather save up and buy something that actually does the job instead of throwing good money after bad.

Ran a 1hp unit for years in my garage and learned the hard way that the hose diameter matters more than anything. Bumping up to a 4 inch main line with smooth transitions helped a ton, even with a cheap collector. Also found that emptying the bag when it's half full keeps the airflow from dropping off a cliff, that clogging issue you had sounds like the bag was packed tight.
