Empty the dirt tank before it gets full

Empty your Bissell vacuum when the dirt tank reaches the fill line, not when it is completely packed. Most Bissell models have a clear tank with a line marked on the side—stop using the vacuum once the dirt reaches that mark. Emptying before the tank is full keeps suction strong and prevents dust from escaping back into your home when you do empty it.

The exact steps depend on your model. Upright vacuums, handheld models, and carpet cleaners all empty differently. Find your model number on a sticker under the tank or on the back of the machine, then follow the steps below for your type.

Key Takeaways

  • Empty the dirt tank when it reaches the fill line, not when it is completely full, to keep suction strong.
  • Most Bissell tanks release with a button or latch near the handle—press it and pull the tank straight down and away from the machine.
  • Tap the tank over a trash can to loosen packed dirt, then rinse the tank with water once a week to prevent clogs.
  • Check the filter after emptying and tap it gently to remove dust buildup, or rinse it if your model allows.
  • Let the tank dry completely before reattaching it to avoid mold and odor inside the machine.

How to remove the dirt tank from an upright Bissell

Upright vacuums like the Bissell PowerForce and Bissell Cleanview have a tank that slides out from the back or side of the machine. Turn off and unplug the vacuum first. Locate the release button or latch—it is usually on the back of the tank where it meets the main body, or on the handle itself. Press the button firmly and pull the tank straight down and away from the machine in one smooth motion. Do not twist or angle it, or it may catch on the frame.

Once the tank is free, carry it to a trash can. Hold it over the can and tap the bottom and sides firmly with your hand or a wooden spoon to loosen the dirt. Most dirt will fall out in chunks. If dirt is packed tight, tap harder or let the tank sit upside down for a few seconds to let gravity help.

How to remove the dirt tank from a handheld Bissell

Handheld models like the Bissell Pet Hair Eraser and Bissell Little Green have a smaller tank that usually pops out from the bottom or back of the unit. Turn off and unplug the vacuum. Look for a release button or tab on the tank itself—press it and pull the tank away from the main body. Some models require you to twist the tank slightly counterclockwise before pulling it out. Check your manual if you are unsure which direction.

Empty the tank over a trash can by tapping it firmly. Handheld tanks are smaller, so dirt usually comes out more easily than from upright models. If the tank has a removable filter inside, you can take it out now to clean it separately.

How to remove the dirty water tank from a Bissell carpet cleaner

Carpet cleaners like the Bissell ProHeat and Bissell Crosswave have a dirty water tank that fills as you clean. Turn off and unplug the machine. The tank usually sits at the back or side of the unit. Look for a release button or handle on the tank itself. Press the button and pull the tank straight out toward you. Some models have a handle on top of the tank—grip it and pull upward to release the tank from its slot.

Carry the tank to a sink or toilet and pour the dirty water down the drain. Rinse the tank thoroughly with clean water before reattaching it. Do not let dirty water sit in the tank for more than a few hours, or it will develop an odor and may grow mold.

Clean the tank and filter while it is out

Once the tank is empty, rinse it with clean water. Use your hand or a soft brush to wipe the inside walls and remove any dirt stuck to the sides. Pay special attention to the corners and the bottom, where dirt collects. Rinse until the water runs clear. For carpet cleaners, rinse the dirty water tank thoroughly and let it drain completely before reattaching.

While the tank is out, check the filter. Most Bissell filters sit inside the tank or clip to the lid. Tap the filter gently over a trash can to shake loose dust. If your model allows it, rinse the filter under cool running water—do not use hot water, which can damage the filter material. Let the filter air dry completely before putting it back in the tank. Never reattach a wet filter, as it will reduce suction and may cause mold to grow inside the machine.

Reattach the tank and check for leaks

Make sure both the tank and the filter are completely dry before reattaching. Slide or push the tank back into place until you hear or feel it click or lock into position. The tank should sit flush against the machine with no gaps. If it does not fit smoothly, remove it and check that the filter is seated correctly inside the tank, then try again.

Before you use the vacuum, plug it in and turn it on for a few seconds to check that air is flowing normally. If suction feels weak, the filter may not be seated properly, or dirt may be blocking the air path inside the tank. Turn off the vacuum, remove the tank again, and inspect the filter and the connection points.

How often to empty and when to deep clean

Empty the tank every time you vacuum, or at least once a week if you use the machine daily. Emptying frequently keeps suction strong and prevents odors. Once a week, rinse the tank with water as described above, even if it does not look dirty—dust settles on the inside walls and reduces airflow.

Once a month, remove the filter and rinse it thoroughly. If your filter is not rinsable (check your manual), tap it gently and replace it with a new one if it looks clogged or discolored. A clogged filter is the most common reason a Bissell loses suction, so keeping the filter clean is as important as emptying the tank.

Frequently Asked Questions

What if the tank is stuck and won't come out?

Turn off and unplug the vacuum, then wait a few minutes. Press the release button again and pull slowly and steadily—do not jerk or force it. If the tank still will not budge, the filter may be clogged and creating a seal. Remove the filter first, then try removing the tank again.

Can I rinse the tank with hot water?

Use cool or lukewarm water only. Hot water can warp the plastic tank and damage the seals. Cool water rinses dirt just as well and is safer for the machine.

How do I know if the filter needs to be replaced?

If the filter looks gray or brown instead of white, or if suction is weak even after rinsing the filter and emptying the tank, it is time for a new one. Most Bissell filters last three to six months with regular use. Check your manual for the correct replacement filter model.

Why does my vacuum smell bad after I empty the tank?

Moisture trapped in the tank or filter causes odor and mold. Always let the tank and filter dry completely before reattaching them. Empty the tank more often, and rinse the tank weekly even if it does not look full. If the smell persists, soak the tank in a mixture of equal parts white vinegar and water for 30 minutes, then rinse and dry it thoroughly.

Do I need to empty the tank before storing the vacuum?

Yes. Always empty the tank and let it dry before putting the vacuum away, even if you only used it for a few minutes. Leaving dirt and moisture in the tank can cause mold, odors, and rust inside the machine over time.
