How Long Does It Take Roomba To Charge? [Roomba 600, 800, 900, i7 & i9 Models]

After talking with several Roomba users, it’s clear that the exact charging time can also depend on the condition of the vacuum and its battery. Regular use and proper maintenance play a crucial role in charging efficiency.

So, while the average charging period falls within two to three hours, your experience may vary based on the model and usage habits.

Roomba 600 Series

The Roomba 600 Series, including models like the 605, 615, 620, 630, 650, 660, and 670, uses nickel-metal hydride (NiMH) batteries. These batteries are known for having a lower energy density, leading to shorter runtime compared to other battery types.

Achieving a full charge from zero generally takes about 3 hours. When charging is complete, the Roomba indicates readiness with a solid green light on its battery indicator. The 600 Series represents an entry-level option, offering essential vacuuming functions with a moderate charging duration.

Roomba 800 and 900 Series

Moving up, the Roomba 800 and 900 Series models, such as the 805, 860, 890, 960, 980, and 990, come equipped with lithium-ion batteries. These advanced batteries provide a higher energy density, resulting in longer runtimes and a more efficient cleaning process. For these models, the charging time varies between 2 to 3 hours, depending on the model and battery level at the start of charging.

A solid green light also indicates the completion of charging. The enhanced battery technology in these series allows for improved cleaning performance and reduced charging times.

Roomba i7/i7+ and s9/s9+ Series

At the top end, the Roomba i7/i7+ and s9/s9+ Series feature the latest advancements with even larger lithium-ion batteries. These models, including the i7, i7+, s9, and s9+, are designed for longer runtimes and superior cleaning efficiency.

The increased battery capacity means these vacuums typically require about 3-4 hours to fully charge from a depleted state. Factors like battery age and ambient temperature can influence the exact charging time. Once fully charged, these models also display a solid green light on the battery indicator.
