My Roomba is leaving marks on the floor.

Due to dirty tracked wheels and a jammed front caster wheel, your Roomba is leaving marks on the floor. When dirt and dust build up in the Roomba’s wheels and internal spaces, it can create undesirable marks. Additionally, a worn-out front caster wheel and a full dustbin can cause your Roomba vacuum to leave behind traces of dirt.

Marks left by Roomba on the floor: 5 reasons and solutions

1: Soiled track wheels

Is your Roomba leaving behind one or two straight lines?

If yes, the tracked wheels are probably soiled.

There are two motor-driven wheels on a Roomba. These wheels are what propel the Roomba throughout the house.

In addition, these are the vacuum components that make direct touch with the floor. That is, these are the components most susceptible to gathering dirt and dust.

The tracked wheels can acquire dirt and dust.

When obstructed dirt comes into touch with any liquid, tracked wheels can produce scratch impressions on the floor.

Additionally, dry dirt can sometimes leave marks. Particularly when the soil becomes very dry and firm.

How to correct:

Determine if the Roomba’s tracked wheels are soiled. Examine it for residues of dirt and dust that have adhered to it.

If there is any, the wheels must be cleaned promptly.

Roomba’s tracked wheels are essential components. Therefore, you may not wish to separate it from its body.

Simply wipe the tracked wheels with rubbing alcohol wipes to remove any dirt that has adhered.

Next, search for debris lodged in their centers. As larger dirt and hair strands can become entangled on them with ease.

Utilize tweezers to remove material from within.

Slowly rotate the wheels with your hand to remove any debris that may be lodged in the wheels.

2: Clogged soil in the crevices

“I have already cleaned the wheel treads. “However, my Roomba still leaves scuffs on the floor…”

If this is the case, then there may be dirt in the Roomba’s crevices.

While such spaces are sealed, little particles of dirt and dust can easily enter them.

When your Roomba begins to operate, clogged dirt will fall out of the gaps.

Consequently, the tracked wheels can “push” the dust onto the floor. resulting in undesirable dirt marks.

This can become more worse if the Roomba encounters a puddle of water on the floor.

How to correct:

You must clean the bottom surface of your Roomba to remedy the issue. Particularly the spaces on it

Simply use a dry broom to sweep away dirt and dust.

If there is still dirt clinging to the object, use compressed air to remove it.

Or, you can tap or shake your Roomba lightly to dislodge the blocked debris.

Caution: Be sure to regulate the air duster’s pressure. As much force can cause delicate Roomba components to become destroyed.

Alternately, you may use a hair clip or a similar object to remove stubborn dirt.

3: Front caster wheel jammed

The front caster wheel of your Roomba could also be obstructed.

The front caster wheel is not propelled by a motor. Its purpose is to direct the Roomba as it rotates and turns while cleaning.

As it is located in the front, it is vulnerable to numerous forms of debris.

And such debris can also become clogged on it. Resulting in the front caster wheel being soiled and jammed.

When this occurs, the front wheel’s sense of direction can become distorted. This is essentially what generates scuff marks on the floor.

How to correct:

Determine if the front caster wheel is soiled. Check to see if any debris is clinging to its body.

If you observe any debris, such as hair stands, remove them immediately.

You can accomplish this by pulling off the hairs.

If that does not work, remove the Roomba unit’s front caster wheel.

To remove and clean the front caster wheel of the Roomba:

  1. Invert the device’s orientation.
  2. Hold the front caster wheel’s body.
  3. Pull it outwards with force.
  4. Remove the wheel from the wheel housing.
  5. Remove any debris from the wheels and housing.
  6. Utilize a dry fabric to wipe the wheel.
  7. Return the wheel to its housing.
  8. Install the front caster wheel back onto the unit.

Every two weeks, clean the front caster wheel for optimal performance.

Nota: removing the unit’s front caster wheel can be difficult. However, be sure to do it with firmness and care to avoid any injury.

4: The front caster wheel is worn out
