Cordless Shark vacuum leaves lines of debris or snowplows larger particles instead of picking them up

Safety first: Remove the battery before cleaning the floor nozzle.

• 1. Check floor mode: Ensure the vacuum is set to the correct floor type (hard floor vs. carpet) according to your model's controls.
• 2. Clean front roller and intake: On DuoClean models, remove the soft front roller and clean off hair and dust. Clear any debris from the front intake opening.
• 3. Inspect brushroll bristles: If bristles are worn down, uneven, or missing, they will not agitate carpet effectively. Replace the brushroll.
• 4. Slow your cleaning pace: Move the vacuum more slowly over debris and make overlapping passes. For large particles, approach them from different angles.
• 5. Replace worn nozzle components: If cleaning does not improve pickup, replace the brushroll and, if applicable, the soft roller with genuine Shark parts.
