As much as I adored dogs in my early days, managing their feeding schedules was... well, chaotic.

Then I stumbled upon my first automatic pet feeder. It was a bulky, basic model, but to me, it was a marvel of modern science. Just press a button and boom—Bruno had his lunch. Magic!

Fast forward to today, and automatic pet feeders have become sleeker, smarter, and more sophisticated. But here’s what many pet owners don’t realize: if you want your high-tech pet assistant to keep working flawlessly, you’ve got to clean and maintain it like a pro.

So today, I’m here as your guide—your Pet Tech Sensei—to walk you through everything you need to know about keeping that feeder fresh, functional, and fur-baby approved.

Let’s dig in.

Why Clean Your Feeder Anyway?

It’s tempting to just fill the hopper, hit "schedule," and forget about it for a week, right? Been there. But here’s the thing: food residue, pet saliva, humidity, and even insects can turn that shiny gadget into a health hazard if you’re not careful.

Let’s break it down:

• Bacteria and mold love dark, warm places with leftover food. Gross, but true.

• Food jams can happen when old kibble clumps together, especially in humid areas.

• Bad smells sneak up over time, especially if your feeder stores oily food.

• Mechanical damage from built-up crumbs or spills can mess with sensors and gears.

  
  

One week, I noticed Rex wasn’t touching his dinner. Turns out, the treat tray had developed a tiny spot of mold I hadn’t seen. After a good cleaning, he was back to devouring his meals with gusto.

How to Clean an Automatic Pet Feeder (Step-by-Step)

We need to appreciate that not all feeders are built the same. Some, like the PETLIBRO Automatic Feeder, make cleaning easy with dishwasher-safe parts. Others may require a bit more elbow grease. But I assure you, the process is generally the same across most models.

Let’s walk through the routine:

1. Power Down & Disassemble

• First things first: unplug or power off the feeder.

• Carefully remove all detachable components—this usually includes:

  • The food hopper (the big storage container)

  • The feeding tray

  • The lid

  • Some models (like WOPET) also have a desiccant holder to keep kibble fresh.

Pro Tip: Take a quick photo before disassembling if you're worried about remembering how it goes back together! (This trick worked for me once.)

2. Wash All Removable Parts

• Use warm water and mild dish soap.

• A soft sponge or brush helps lift any greasy residue or stuck kibble bits.

• Rinse thoroughly; soap left behind can alter the taste of food (pets will notice!).

• Let them air dry completely before reassembly to avoid moisture buildup.

Feeders like PETLIBRO AIR and Voluas often use BPA-free plastic that’s gentle to clean and resistant to oil—just avoid abrasive scrubbers.

3. Wipe the Main Unit

• Never submerge the base or electronic parts.

• Use a damp microfiber cloth or alcohol-free wet wipe.

• Gently clean around:

  • Buttons or touchscreen areas

  • Sensors (some models have infrared sensors near the tray)

  • Openings where food travels

4. Check the Mechanics

• Look for leftover kibble stuck in:

  • The dispensing chute

  • Rotating paddles or wheels (these can jam!)

• Turn the paddles manually if possible to ensure smooth movement.

• A soft toothbrush works wonders for small corners or awkward angles.

5. Reassemble and Test

• Once everything is bone-dry, reassemble the feeder.

• Do a manual test feed using a few pieces of dry kibble to check:

  • If the food flows smoothly

  • If the tray aligns properly

  • If there are any unusual sounds or sluggish movement

Regular Maintenance Tips (That Will Save You Money)

Fellow pet owners, cleaning is one thing, but maintenance goes beyond hygiene. It’s about making sure your investment lasts for years and keeps your pets well-fed no matter what.

Well, here are some good habits, small but make a huge difference (try them out):

✔ Weekly Mini Clean

• Wipe the tray daily or every other day.

• Empty crumbs from the hopper once a week.

• Check for treat dust build-up near moving parts.

✔ Monthly Deep Clean

• Go through the full disassembly and cleaning routine at least once a month.

• This is when you replace the desiccant packs (if your feeder uses them), which help keep kibble crisp and fresh.

• Clean around the motor housing gently with compressed air if crumbs accumulate.

✔ Use Compatible Kibble

• Stick to dry food only. Wet food will clog or rot unless your feeder is designed for it.

• Use round or oval kibble less than 0.5 inches for smooth dispensing.

• Some feeders, like the Petlibro Granary Series, perform best with consistent kibble shapes.

✔ Monitor Battery and App Connectivity

• If your feeder has a battery backup, check the battery every 2–3 months.

• For Wi-Fi-enabled feeders, like WOPET SmartFeeder, ensure app firmware is up-to-date. Old software can cause scheduling bugs or missed feedings.

True Story: The Bruno Incident

Bruno once managed to drool into the feeder while waiting for lunch. The drool got into the kibble funnel, and by day three, let’s just say the smell could wake the neighbors. Since then, I clean the spout every few days with a dry brush and wipe the tray twice a day.

Bruno’s happy, the feeder’s happy, and I get to keep my nostrils intact. Don't be like me, since you're now on the know.

Final Thoughts From Your Pet Tech Sensei

I figure cleaning your automatic pet feeder isn’t a chore—it’s an act of love. And a little effort goes a long way. You wouldn’t eat off the same plate for a month without washing it, right?

Neither should your pet.

So next time you fill up that hopper and schedule those meals, take five extra minutes to check that it’s clean, running smoothly, and delivering happiness with every scoop.

Your pet deserves it, and honestly, so do you.
