The battery life of cordless vacuum cleaners can vary significantly depending on the brand, model, and the type of cleaning tasks performed.
High-end cordless vacuum cleaners equipped with lithium-ion batteries typically offer longer runtimes compared to lower-priced models with older battery technologies. Some cordless vacuums may provide anywhere from 20 minutes to 1 hour or more of continuous cleaning on a single charge.
The runtime also depends on the cleaning mode used. Many cordless vacuums have multiple power settings, and using higher suction power will generally reduce the battery life.
If you are considering purchasing a cordless vacuum cleaner, I recommend checking the product specifications and reviews for the specific model you are interested in. Manufacturers usually provide information about battery life in their product descriptions, and user reviews can offer real-world insights into the vacuum's performance and battery performance.
Keep in mind that battery technology continues to improve, so newer models may have longer runtimes than older ones. Additionally, some cordless vacuums offer removable and replaceable batteries, which can be useful if you need extended cleaning time and have spare batteries available.
