r/VacuumCleaners on Reddit: Shark Vacuum Sudden Loss of Suction
May 11, 2022 -

So, to start, I know it isn't the container itself because I emptied it in the hopes it would work. I used a smaller handheld to clean the top of the sponge filter, too. Still nothing.

What happened: I was cleaning minutes ago and accidentally ran the hose over a plastic bag (was filled, so the bag didn't swoosh into the vacuum). I heard a pop and kept looking all over the vacuum for a hole or something. The only indicator I have is the little indented "hole" on the right side next to the container. If I block the hose, it suddenly starts pulling air through that, but it stops if I lightly block this "hole" again. I still get low suction in the rest of the vacuum, so I'm not sure what happened. I wasn't even sure what to ask online about this since I'm pretty lost on what to even try to do. I hope I didn't break it!

That hole near the container that makes a loud rushing noise while you plug the main hose is just a release valve that opens when the main air path is blocked so the motor is still able to "breathe" when the hose is jammed. Have you checked all the piping, including inside the head? If you accidentally sucked large debris into it, you very well may have clogged it. A good way to trace a clog is to start from the beginning. If it is not flowing properly at the head, remove the wand and see if it is flowing properly at the end of the wand. If it is, then the clog is inside the head. If not, remove the wand and see if the airflow is correct at the end of the hose. If it is, then check for clogs in the wand. If it still feels clogged, do the same thing with the hose, which is connected directly to the bin. If the flow feels normal where the hose mounts, the clog is in the hose. Depending on where the clog is, you can use various tools like a broomstick or screwdriver to remove the clog. Also, if you do not do this already, the Sharks like to have their filters washed a couple times a month.

Located at the top of the vacuum is a slider with three settings: Thick Carpet/Area Rug, Carpet/Low Pile, and Hard Floor. Adjust the slider to the floor being vacuumed. The dustbin may be full and cannot hold any more particles or debris. Remove and empty the dustbin, and clean/replace all filters.

Shark vacuum not sucking? Here's how to fix it - Digital Trends
May 5, 2025 - If that happens, it may be a good idea to start looking for a new vacuum cleaner instead of attempting repairs. Some Shark models use an internal battery that needs to be recharged from time to time. If this is the case, check your battery charger to make sure it is working properly, connecting to the battery properly, and that the connectors are not dirty or damaged. If it’s been a few years since you started using the vac, you may need to buy a new battery. A weaker battery will lead to lower suction, something you can usually tell simply by listening to the motor when you turn the vac on.

February 20, 2022 - The rest of the machine felt klutzy: bulky and hard to maneuver, unusable powered lift away because the head would lift off the floor on the return stroke, stiff and short hose and because of the open head design, more likely to pull in inadvertant objects like cords and cables. And surprisingly tiny dust bin for the size of the machine! I am tired of having to clean the dust cup on a full size machine after every room! I wonder if Shark will continue with the DuoClean heads for their next model release.

r/VacuumCleaners on Reddit: Shark Duo Clean stopped working
March 2, 2020 -

I’ve had this vacuum for a few months, bought it new. A few days back it started making a loud suctioning noise and the suctioning got a little less, but I couldn’t seem to find any sort of blockage anywhere. Then a day back, it suddenly stopped suctioning all together. I did smell a slightly burning smell come from the vacuum. The only thing that works now is the brush roll, but no suction at all. Any ideas of what may have happened to this vacuum? And is it something that may be fixable at home or need to send in for warranty repair?

Does the suction motor appear to be running at all? If it is, definitely check the filters (both the foam/felt pre-filter and the pleated exhaust filter) for being dirty, as well as for any blockages by removing parts until you get suction again. Also check the screen in the center of the single cyclone setup.

If the suction motor is not working, a vac shop may have a spare unit but I know many won't even look at a Shark due to the lack of parts available. Unfortunately, it may be better at that point to get a new/different machine.

August 5, 2025 - Make sure not to use any harsh chemicals or detergents, as these can damage the material. Once washed, allow the dust cup to dry completely before reattaching it to the vacuum. This prevents moisture from building up inside the vacuum, which could lead to mold growth or unpleasant odors over time. If your Shark Duo Clean vacuum is losing suction even after you’ve emptied the dust cup, there might be other factors at play.
