Matic is making a noise

Fan noise while docked

Matic runs a cooling fan continuously while sitting on its dock, and will occasionally ramp it up to purge humidity from the vacuum system. Matic also runs its vacuum motor briefly at high RPM to reduce humidity in HEPA Bag's bin. Some fan noise while docked is expected and by design. This is not a sign of a problem.

If the fan noise seems unusually loud or has been running at high speed for an extended period, try the following:

1. Open Matic's lid while the sound is occurring. If the noise stops immediately, this is the vacuum motor's humidity purging cycle. Normal behavior that should resolve on its own.
2. If the noise continues with the lid open, try moving Matic off its dock to determine whether the sound is coming from Matic or the dock itself. In both cases, contact support and bring your findings with you.
   

High-pitched whine during vacuuming

A high-pitched whine or squeal during vacuuming is one of the most common noise issues. It's often caused by a full dust bag, but can also indicate a hardware issue with the vacuum motor.

1. Check your HEPA bag and replace it if it's more than a quarter full. A filling bag causes the motor to work harder and run louder.
2. Run a short cleaning session and check if the sound has improved.

If the high-pitched whine persists after replacing the bag and reseating the brush roll, contact support with a video of the noise. This may be a known motor resonance issue that our team can address through a repair.

Squeaking during movement

This is caused when one of the drive wheels can momentarily lose traction during mopping and produce a squeaking sound. This doesn't indicate any damage to your Matic, but we understand it can be frustrating to hear.

This can happen due to a combination of factors, including:

• Floor characteristics, such as very slick or heavily textured surfaces, which can make traction harder to maintain during mopping.
• Mopping dynamics, such as downward mop pressure, the amount of water on the floor, and how quickly the robot accelerates.

Because this is caused by a combination of factors rather than a single part, our engineering team is prioritizing software improvements that help Matic adapt in real time. These include adjusting mop pressure when traction is limited and smoothing wheel acceleration on certain floor types. This is a top priority for our team, and we'll share updates here once the improvement is live. In the meantime, there isn't a workaround beyond what's noted above

Grinding noise

Grinding is not a typical or expected sound and often points to a hardware issue with the drive or cleaning head motor.

1. Check for any visible debris caught in the brush roll, wheels, or cleaning head, and remove it if found.
2. Run a short session and note whether the grinding is constant or only occurs during specific movements (like turning).

If grinding continues, contact support with a video. This is usually a hardware issue rather than something to troubleshoot further at home.
