Not all vacuums can run without a filter. So make sure that your shop vac can support itself without one.

Tip: if you decide not to have a filter of any kind in your shop vac, make sure that you only use it in open areas. This will prevent the dust from being blown back out into your home, hence defeating the purpose of a vacuum cleaner.

If you place some water in the bottom of the tank, it will trap some dust, but not all of it. If you have a vacuum cleaner that uses water as a filtration system, then you can apply the above method without any hesitation whatsoever. Otherwise, we recommend you not to do it, as it is always a dangerous thing for the lifespan of your equipment. Here’s a video of a shop vac that uses water as a filtration system.

Much like a filter, it’s advisable to use a dust bag if you are vacuuming dry stuff. When you suck dry things without a dust bag, it will create a mess in the canister.

what can you vacuum with a shop vac?

The great thing about a shop vac is its ability to suck up just about everything with regard to dry and wet debris. Nails, liquid, and screws to name a few. Unlike a normal vacuum cleaner, these won’t stop a shop vac. Even pet hairs are no match for their power.

If your basement floods, no worries! You can suck out the excess water from its floors. Sure a shop vac isn’t a long-term option, but it will help you when you need it the most. Most vacs have a float that will automatically shut off the suction power if the canister is full. Watch out when your shop vac changes pitch and lose all its suction. When it happens, you must empty the tank immediately before continuing.

Can you use a shop vac to clean ponds?

We won’t recommend you use your shop vac to clean ponds or any large body of water. The biggest reason is that it fills up too fast and you have to empty it often. Also, it may have a chance to encounter a large repair either due to over-usage or significant clogging due to random gunk in the pond. Trust us, we’ve tried it, and it isn’t worth it!

But, if you have no option other than using a shop vac, make sure to attach an output hose. The output hose is a major thing to have as it allows the water to flow right back out. Sometimes, even a quality output hose won’t be able to keep up with the incoming water. And it may end up taking up a lot of time to clean the pond than you expected.

What you can use instead is a water pump. It will suck up a large amount of water and then use a shop vac to clean the rest.

How to improve the performance of the filter?

Determine what you are going to do with the filter. If you are going to vacuum water and other wet debris, then it is a must you should go with a foam filter. On the other hand, if you will only use it for cleaning dust and other dry stuff, a dust bag is more than enough. Too many people worry about what type of filter they want and don’t care about maintaining it.

Don’t do that. Maintain the filter and the filter cartridge. Do it right and it’ll increase the lifespan of the filter.

There is no magic formula for increasing the performance of a filter. So, do these things the right way and you will see a major improvement in the performance of the filter.
