5 Things to Know About the SilentBot S1's Battery and Charging

The SilentBot S1 runs for 90 minutes in standard mode. That is enough to clean a decent apartment on one charge.

It takes 3 hours to fully recharge. This is a typical recharge time for a quiet-focused robot vacuum.

The trade-off for whisper-quiet operation is usually a smaller battery. The SilentBot S1 still manages solid runtime despite this compromise.

You trade some cleaning speed for silence. The battery numbers work out fine for most users who prioritize low noise.

The 90-minute runtime and 3-hour charge cycle are solid for this category. Expect this performance from a bot designed to be quiet rather than fast.
