SmartAI V6 80Mins Cordless Vacuum Cleaner 65KPA 650W Powerful Suction Vacuum, 24000mAh Big Battery Vacuum Cleaner

With extended use, the actual battery runtime differs from the advertised 80 minutes — in Turbo mode it lasts approximately 15 to 20 minutes, in Auto mode 35 to 45 minutes, and in Eco mode up to 90 minutes. Charging takes relatively long (approximately 20 percent per hour), which is understandable given the battery capacity. The vacuum is louder than competing models but still acceptable. Some buyers noticed that power gradually decreases during extended use in turbo mode.

Critical reviews point to a suction power problem — some buyers report that the vacuum does not suction at all or suctions very weakly, which contradicts the positive ratings. The Smart mode seems unpredictable to some users and randomly changes power levels. Another complaint is that the vacuum does not remember the last used mode. The proportion of critical ratings is low (0.7 percent), but their content suggests a possible quality issue with individual units or product variants.
