January 13, 2026 – A serious incident involving a Shark Matrix Robo vacuum with a lithium-ion battery has been reported, leading to a significant fire. The incident, which occurred on December 21, 2025, involved the Shark RV2310CGUS model, where a “pop” sound was heard, followed within seconds by “floor-to-ceiling flames,” highlighting the critical safety risks associated with lithium-ion battery failures in consumer appliances.
Product Details
Incident Overview
On December 21, 2025, a consumer was watching television in their living room when they heard a distinct “pop” sound emanating from their Shark Matrix Robo vacuum (model RV2310CGUS), which was equipped with a lithium-ion battery. Approximately five to six seconds after the initial sound, the vacuum erupted in flames. The fire rapidly escalated, with witnesses describing “flames from floor to the ceiling,” indicating a severe and fast-spreading blaze within the residential space. The incident suggests a catastrophic failure of the product’s lithium-ion battery, leading to a thermal runaway event.
Safety Concerns
This incident raises significant safety concerns, primarily revolving around the potential for lithium-ion batteries in robotic vacuums to unexpectedly ignite, posing severe hazards:
- Immediate Dangers: The rapid onset of “floor-to-ceiling flames” indicates an extremely dangerous situation, with immediate risks of severe burns, smoke inhalation, and the rapid spread of fire throughout a home. Such fires can quickly engulf flammable materials, making escape difficult and perilous.
- Long-term Risks: A fire of this magnitude can lead to extensive property damage, including structural compromise, destruction of personal belongings, and lingering smoke and soot contamination, requiring costly and lengthy remediation. Inhalation of combustion byproducts can also have long-term respiratory health implications.
- Who Might Be Affected: Occupants of the home, including adults, children, and pets, are at direct risk of injury or death. First responders, such as firefighters, also face increased risks when dealing with lithium-ion battery fires, which can be challenging to extinguish due to their intense heat and potential for re-ignition.
- Property Damage Potential: As evidenced by the “floor-to-ceiling flames” description, the potential for extensive and irreparable property damage is very high. Lithium-ion battery fires are known for their intensity and ability to cause significant destruction in a short amount of time, potentially rendering homes uninhabitable.
What Consumers Should Do
Consumers who own a Shark RV2310CGUS robot vacuum or similar lithium-ion battery-powered devices should take proactive steps to ensure their safety:
- Immediate Steps in Case of Fire: If a lithium-ion battery-powered device ignites, evacuate the premises immediately and call 911 (or your local emergency number) from a safe location. Do NOT attempt to extinguish a large lithium-ion battery fire yourself, as it can be extremely dangerous and specialized extinguishing agents may be required.
- How to Check Your Product: Locate the model number on your Shark robot vacuum. It is typically found on a label on the underside or back of the unit. Compare it to the RV2310CGUS model number reported in this incident.
- Prevention Measures:
* Charge Safely: Only use the charging dock and power adapter supplied by the manufacturer. Avoid third-party chargers, which may not meet safety specifications.
* Monitor Charging: Do not leave charging robot vacuums unattended, especially overnight or when no one is home. Charge them on hard, non-flammable surfaces, away from carpets, curtains, and other combustible materials.
* Inspect for Damage: Regularly inspect the vacuum and its charging cord for any signs of damage, such as frayed wires, cracks, or swelling. A swollen battery is a critical indicator of potential failure and should be immediately taken out of service and disposed of properly.
* Avoid Physical Damage: Handle the robot vacuum with care to prevent drops or impacts that could damage the internal battery.
- Reporting Procedures: If you experience a similar incident or discover a defect with your product, report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov.
