How to Change Batteries in Swiffer WetJet

When your Swiffer WetJet stops spraying, sounds weak, or its indicator light fades, it’s usually not broken—it just needs new batteries. The Swiffer WetJet is a handy power mop that runs on four AA batteries, giving the sprayer enough power to mist your cleaning solution across the floor. Changing the batteries is quick and easy, but doing it the right way ensures your WetJet keeps working smoothly.

Before you start, make sure you have everything ready:

• 4 new AA batteries (alkaline works best)
• A small Phillips head screwdriver (some models need it)
• A flat, stable surface to work on

Key Takeaways

• Battery Type: The Swiffer WetJet runs on four AA batteries—always replace all four at once for even power.
• Compartment Location: The battery door is usually in the handle or neck area, secured by either a latch or screw.
• Prep Matters: Always remove the cleaning solution bottle and lay the WetJet flat before starting.
• Battery Orientation: Match the + and – symbols carefully—one misplaced battery can stop the sprayer.
• If It Still Doesn’t Work: Double-check the door closure, battery direction, and bottle placement before assuming it’s faulty.

Keeping your Swiffer WetJet in top shape takes just a few minutes and saves you from unnecessary frustration later. With fresh batteries and a little care, your floors will shine again in no time.

Safety and Preparation

Before diving in, take a moment to prep your workspace—it’ll help you avoid spills or mishaps.

1. Power Off: Make sure the WetJet isn’t spraying or accidentally triggered while you’re handling it.
2. Remove the Solution Bottle: Gently press the release button and pull out the cleaning solution bottle. This prevents leaks and gives you clear access to the handle area.
3. Lay It Flat: Place your WetJet on a clean, level surface, like a table or counter. This keeps it steady while you work on the battery compartment.

Once you’ve done these steps, you’re ready to find where those batteries hide.

Locating and Accessing the Battery Compartment

The Swiffer WetJet’s battery compartment is cleverly tucked into the upper handle or neck area, depending on the model. You’ll usually find it just below the spray button or behind a small door marked with a battery symbol.

1. Find the Compartment: Look for a small rectangular panel on the handle. It might be slightly recessed with a latch, clip, or screw securing it.
2. Identify the Locking Mechanism:
   • If your model has a screw, grab your Phillips head screwdriver and loosen it—no need to remove it completely. It’s often a captive screw, meaning it stays attached to the door even when loosened.
   • If it has a latch or tab, press or slide it gently until the cover pops open.
3. Open Carefully: Once released, lift the battery door and set it aside. Inside, you’ll see four battery slots, usually arranged in two neat rows.

Now that you’ve accessed the compartment, you’re ready to remove the old batteries safely.

Replacing the Old Batteries

Once the compartment is open, it’s time to swap out the power source.

1. Remove the Old Batteries:
   Tilt the handle slightly so the batteries slide out on their own. If any seem stuck, gently nudge them using your fingertip or a non-metallic tool (like a pencil eraser). Avoid using anything metal—it could cause a short circuit.
2. Dispose of Properly:
   Never toss old batteries in the regular bin. Instead, take them to a local recycling point or battery disposal center—most supermarkets and hardware stores have one.
3. Check for Dirt or Corrosion:
   Take a quick look inside the compartment. If you see any white powder or rust (a sign of corrosion), wipe it gently with a dry cloth. Avoid liquids—they can damage the electrical contacts.
4. Insert New Batteries:
   Line up each battery according to the positive (+) and negative (–) markings inside the compartment. It’s easy to miss this step, but orientation matters—a single misplaced battery can stop the WetJet from working altogether.
   Once all four batteries are in, make sure they’re snug and level.

Next up: we’ll close everything back up and test your WetJet to make sure it’s spraying properly.

Reassembly and Testing

You’re almost done—now it’s time to put everything back together and make sure your Swiffer WetJet is back in action.

1. Close the Battery Compartment:
   Carefully place the battery door back over the compartment.
   • If it’s held by a screw, tighten it just enough to secure the cover—don’t overdo it, or you could strip the threads.
   • If it uses a latch, listen for that satisfying click that means it’s locked in place.
2. Reinstall the Cleaning Solution Bottle:
   Slide or click the bottle back into its slot until you hear it snap into place. Make sure it’s seated correctly; a loose bottle can stop the sprayer from working.
3. Test the WetJet:
   Hold the handle upright and press the spray button. You should hear the small motor humming and see the cleaning solution spray out smoothly.
   • If it sprays well: Great—you’ve successfully changed the batteries!
   • If it doesn’t spray: Double-check the battery orientation, ensure the compartment door is fully closed, and confirm the bottle is properly clicked in.

Troubleshooting (What to Do If It Doesn’t Work)

If your Swiffer WetJet still won’t spray after replacing the batteries, don’t worry—these quick fixes usually solve the problem.

1. No Spray or Weak Spray:
   • Check that all four batteries are installed in the correct direction.
   • Ensure the battery door is tightly closed. A loose connection can interrupt the power flow.
   • Make sure the cleaning solution bottle is fully seated—press down until you hear a click.
2. Leaking Solution:
   • Remove the bottle and check the cap. If it’s not fully tightened, the liquid can leak or fail to pressurize.
   • Wipe away any excess cleaner around the nozzle before reinserting the bottle.
3. Still Nothing Happens:
   • Replace the batteries with a fresh set of name-brand AAs to rule out weak power cells.
   • If it’s still unresponsive, contact Swiffer Customer Support through their official help page for troubleshooting or replacement options.

By following these steps, your Swiffer WetJet should be back to spraying effortlessly—keeping your floors spotless without any hassle.

Conclusion

Changing the batteries in your Swiffer WetJet is a simple fix that can instantly bring your mop back to life. Most performance issues—like weak sprays or no power—come down to dead or incorrectly placed batteries. By following a few quick steps, removing the solution bottle, and installing four fresh AA batteries, you’ll keep your WetJet running smoothly for months.

A little maintenance goes a long way. With this easy routine, you’ll spend less time troubleshooting and more time enjoying spotless, streak-free floors.
