The Tristar KR-3140 handheld cordless vacuum is a compact cleaning tool designed for quick dry and wet suction on small surfaces. Powered by a 65 W motor and a 7.4 V lithium rechargeable battery, it provides up to 24 minutes of runtime and returns to full charge in approximately 3.5 hours. The unit is lightweight at 0.45 kg net weight and offers a 0.12 L dust bin capacity, making it suitable for brief cleaning tasks in the home, car and other confined spaces. Its maximum noise level is 65 dB and the vacuum supports wet suction without a washing function.

Advantages

The cordless design and low weight enable easy handling and portability for short cleaning sessions. A lithium rechargeable battery delivers consistent power for up to 24 minutes of operation, while a relatively short charging time reduces downtime. The compact 0.12 L dust container and simple on/off control make the device practical for fast spot cleaning. Wet suction capability expands the range of tasks the vacuum can perform beyond dry debris removal.

How to use

Charge the Tristar KR-3140 fully before first use, allowing about 3.5 hours until the battery is ready. Use the on/off switch to start the unit and guide the handheld nozzle over the area to be cleaned. For wet suction, pick up small liquid spills carefully and avoid continuous pickup of large volumes of liquid. Empty the 0.12 L dust container after each use or when full, following the manufacturer's instructions for safe disposal of collected debris and liquids. Store the vacuum in a dry place and keep the charging cable and accessories accessible for the next use.

Recommendations

Do not use the vacuum to pick up large amounts of liquid, hot ashes or sharp objects. Regularly check and clean the dust container and any filters to maintain suction performance. Charge the lithium battery at room temperature and avoid prolonged storage in a fully discharged state to preserve battery life.
