Since you have a bare floor, why don't you put an extension to your uptake....get tubing/hose and put it just off the floor. Try to place it were the dirt accumulates. Here's one of my "poop suckers":
It works very well, and in the 5 1/2 years the 300 gallon tank has been running, there has been nothing to vacuum out. Since I posted about my poop suckers several years ago, others have tried it on their bare floor tanks and it's worked for them.
If this doesn't work for you, you may be overstocked or just need more filtration. The kind of fish you keep in there can also make a big difference. For instance, large plecos and oscars are real poop machines. BTW, we used to have two large plecos and two oscars in the tank (they passed away), and there was still nothing to vacuum out of the tank.
Depending on what kind of filter you have, you can make an extended tube uptake out of pipe or hose. Love poop suckers so much, we're putting six or seven on our large tank when we set it up. I'm not into vacuuming poop out of tanks, and I'd rather feces and debris be sucked right off the floor than be smooshed and broken up in the water and then removed by the filter.
