Roborock Error 23 is officially defined as a Dock Location Error. In plain English, it means your robot has lost its way home. The machine knows it needs to charge, and it’s searching for that “homing beacon” from the dock, but the signal is either blocked, garbled, or the robot is physically unable to mount the charging base due to an environmental obstruction.

For your safety and to avoid voiding the warranty, please check the official docs.
Listen, I’ve seen this a hundred times in the shop. You’ll probably see your Roborock spinning in circles right in front of the dock, or maybe it’s “shuffling” back and forth like it’s trying to find the right angle but keeps failing. It might even give up and stop in the middle of the room, leaving you with a dead battery and a half-dirty floor. Don’t go shopping for a new vacuum yet—this is a classic communication breakdown, and nine times out of ten, we can fix it right here in your living room without spending a dime on parts.
Symptoms of Error 23
When Error 23 strikes, the machine doesn’t just stop; it usually puts on a bit of a performance first. You’ll notice the robot approaching the dock with hesitation. It might bump into the dock harder than usual, or it might back up, realign, and try again five or six times before the voice prompt finally announces the error.
Physically, you might notice the indicator light on the dock flickering or staying dim when the vacuum tries to approach. In some cases, the robot will actually mount the dock, but the charging “handshake” fails, causing it to back off and trigger the error. If your app is open, you’ll see the “Docking” status fluctuate wildly before the red Error 23 notification pops up. If the unit is making a grinding noise while trying to dock, that’s a sign the wheels are slipping on the dock’s ramp—a major trigger for this specific code.
How to Fix Roborock Error 23 (Step-by-Step)
-
The “Deep Clean” of the Optical Path:
First things first: take that microfiber cloth and some isopropyl alcohol. Clean the front bumper of the robot—that’s where its “eyes” are. Pay special attention to the dark plastic strip. Next, go to the dock and clean the large plastic window where the signal comes out. Even a fingerprint can refract the IR beam and cause Error 23. While you’re at it, flip the robot over and wipe down the cliff sensors and the charging contacts. Grime on the contacts can cause a “false dock” where the robot thinks it’s home but doesn’t feel the electricity, leading it to back off and error out.
-
The “Rule of Three” Dock Placement:
I’ve seen too many people hide their docks in “cubby holes.” You need clear space. Ensure there is at least 0.5 meters (1.6 feet) of clearance on both sides of the dock and at least 1.5 meters (5 feet) of clear space in front. Safety Warning: Always ensure the dock is on a flat, level surface. If the dock is tilted even 2 degrees because it’s half-on/half-off a rug, the robot’s sensors won’t align with the dock’s charging pins, and you’ll get Error 23 every single time.
-
Hard Reset and “Power Drain”:
Sometimes the logic board on the dock gets “locked” in a loop. Unplug the dock from the wall. While it’s unplugged, take the robot and hold the power button down until it shuts off completely. Wait 60 seconds. This allows the capacitors in the dock to fully discharge. Plug the dock back in and turn the robot back on. This forces a fresh “handshake” between the two devices.
-
Check for Physical “Slippage”:
If your dock is on a hardwood floor and moves when the robot tries to climb it, the robot will lose its coordinates. Use the adhesive pads that came with the dock, or a small piece of double-sided tape, to secure the dock to the floor. If the robot’s wheels are worn down (bald), they won’t have the traction to climb the dock’s ramp. Inspect the tread on the main drive wheels; if they look like slick racing tires, they need to be replaced.
-
Advanced: Inspect the Charging Contacts & Cable:
Check the power cable going into the back of the dock. If it’s loose, the IR beacon might be flickering. Safety Warning: Unplug the dock before inspecting the pins. Use a small screwdriver to gently press the spring-loaded charging pins on the dock. They should bounce back freely. If one is stuck down, use a drop of alcohol to loosen any sugary spills (like spilled juice) that might be gumming up the works.
- Repair Difficulty: Low (No advanced technical skills required for most fixes).
- Estimated Time: 15 to 30 minutes of hands-on troubleshooting.
- Tools Needed:
- High-quality Microfiber cloth (don’t use paper towels, they scratch).
- 70% Isopropyl Alcohol (for cleaning contacts).
- Flashlight (to inspect the infrared windows).
- A Phillips head screwdriver (only if we need to check the dock’s internal cabling).
- Estimated Cost: $0 – $15 (Unless the dock’s infrared motherboard is fried, which is rare).
Why is my Roborock showing Error 23?
H2: Why is my Roborock showing Error 23?
In my experience, this isn’t usually a “part failure” right out of the gate. It’s usually a failure of the Infrared (IR) Handshake. Here are the three most common reasons your robot is acting like it’s lost in a fog:
- The “Cat Hair Fog” (Sensor Contamination): Both the robot and the dock use infrared light to talk. The dock sends out a “V” shaped beam, and the robot looks for it. Over time, a film of fine dust, pet dander, or even floor wax builds up over the IR windows. If the light can’t get through, the robot is essentially driving blind. It’s like trying to drive through a blizzard with a muddy windshield.
- Environmental Interference: Modern homes are full of IR noise. If you’ve placed the dock in direct sunlight or near a large mirror, the IR signal from the dock bounces off those surfaces. The robot sees three “homes” instead of one and gets confused. Also, if you’ve tucked the dock into a tight corner or under a low-clearance cabinet, you’re choking the signal.
- Mechanical Resistance: If the dock is on a high-pile carpet or a slippery tile floor, the robot might be physically unable to get its charging pins to line up. If the wheels slip during the final “push” onto the dock, the internal odometer doesn’t match the visual data, and the software throws Error 23 because it thinks it’s stuck or the dock has moved.
- Voltage Irregularities: Sometimes, the dock’s internal power board develops a “ripple” in the voltage. It’s enough to power the light, but not enough to maintain a stable IR beacon. This is often caused by household power surges or “dirty” power from an old outlet.
How to Prevent Error 23
Once you’ve got it back to the barn, you want to keep it that way. Here is the veteran’s secret to never seeing Error 23 again:
1. The Weekly Wipe: Make it a habit. Every Sunday, or whenever you empty the bin, take 10 seconds to wipe the dock window and the robot’s bumper. Dust is the #1 enemy of robotic navigation. If you keep the “eyes” clear, the logic board doesn’t have to work nearly as hard.
2. Eliminate “Light Pollution”: If you have a room that gets blasted with afternoon sun right where the dock is, move the dock. Sunlight is full of infrared radiation, which can “drown out” the dock’s beacon just like a loud noise drowns out a whisper. Keep the dock in a shaded area of the room for 100% docking reliability.
3. Use a Surge Protector: These docks have sensitive IR emitters. A small power spike can weaken the LED inside the dock. Plugging your dock into a high-quality surge protector (not just a cheap power strip) will extend the life of the dock’s internal circuitry by years.
Frequently Asked Questions
Q: Can I just move the robot to the dock manually?
A: You can, but it won’t clear the error in the long run. If you place it manually, the robot might charge, but it hasn’t “learned” where the dock is. The next time it runs, it will still struggle to find its way home. It’s better to fix the underlying sensor or placement issue so the robot can dock itself.
Q: My sensors are clean, but it still can’t find the dock. Is the dock broken?
A: It’s possible. To test this, use your smartphone camera. Point the camera at the dock’s IR window while it’s plugged in. Most phone cameras can see infrared light. You should see a faint purple or white flickering light through the screen. If you see no light at all, the dock’s IR emitter is dead, and you’ll need a replacement base.
Q: Does the “Error 23” mean my battery is dying?
A: Not necessarily. While a weak battery can cause the robot to act “erratic” as it loses voltage, Error 23 is specifically about the location and navigation to the dock. If the battery were the primary issue, you would more likely see Error 13 (Charging Error) or the unit simply dying before it even tries to get home.
