Why does the Roborock Handheld Cordless Vacuum Cleaner H6 take longer to charge in summer?
The Roborock Handheld Cordless Vacuum Cleaner H6 has a complete battery charging and discharging management system. In the hot summer, battery temperature may be higher after use. To prolong battery life and ensure charging safety, the machine will wait for the battery to cool down before charging. As such, charging time becomes longer in summer.
