Dear Valued Customer, Thank you for your feedback! We're glad you like the usability, attachments, and price of our vacuum. We apologize for the battery runtime concern. Your model has a brushed motor, which offers good suction and value but inherently has a shorter battery life (typically 10-20 minutes) than brushless models. We regret not clearly communicating this upfront and will improve transparency. Battery care tips: Cool 30 mins before recharge. Recharge before fully drained (below 20%). Store in cool, dry place. We appreciate your feedback! Best regards, Shenzhen Sinofly Electronic Company Limited
