Carefully read the asterisks on the Samsung website. They have written: "High-capacity batteries allow you to use the vacuum cleaner for up to 80 minutes * without recharging." And below in small print. "* When using 2 fully charged batteries." In my opinion, it was necessary to write "400 minutes of work from 10 accumulators". It doesn't matter if it comes with one battery. The main thing is to impress an inattentive client with numbers! The vacuum cleaner turns on by default in turbo mode (you can turn on economy, but its suction power is no good) and the operating time in turbo mode is + - 20 minutes. In the economy one, it will probably last about 40 minutes.
