Hello Bob.
Thank you for your feedback on the 24V Cordless White Stick Vacuum (SKU 4707102). We are glad to hear you find it handy, and we understand your concern regarding battery runtime. For improved performance, ensure the battery is fully charged before each use and that the filter and dust bin are kept clean, as restricted airflow can impact efficiency. Runtime will vary depending on the power setting: on low/eco mode you can typically expect the longest run time (often up to around 30 -45 minutes depending on conditions), medium settings generally reduce runtime to a moderate range, and high/power mode provides the strongest suction but the shortest runtime (often around 10 -20 minutes depending on surface type and usage). This model is compatible with the Greenworks 24V platform, and upgrading to higher-capacity batteries such as the 4.0Ah or 5.0Ah options can help extend overall run time compared to standard lower Ah batteries. If you continue to experience shorter-than-expected performance, our success team can help review usage conditions and confirm compatibility to ensure you are getting optimal results from your unit. They can be reached either using the online chat function, on Greenworks Tools page, or by calling 1-888-909-6757.
