iRobot Roomba 681 (Black, Bagless)

How long does the battery last and how long does it take to recharge?

The lithium-ion battery provides 1.5 hours of continuous cleaning time. Recharging takes approximately 3 hours when the robot returns to its charging dock automatically. The battery maintains consistent performance throughout its lifespan and doesn't suffer from memory effect like older battery technologies.

Can it clean different types of flooring effectively?

Yes, the Roomba 681 automatically adjusts between carpet, hard floors, tiles and linoleum. It uses sensors to detect surface changes and modifies suction power accordingly. The dual-action cleaning system works effectively on both low-pile carpets and smooth surfaces, though it may struggle with very thick or high-pile rugs.

How often should I empty the dustbin and replace the filter?

Empty the 0.6-litre dustbin after each cleaning session or when the indicator shows it's full. The HEPA filter should be replaced every 2-3 months depending on usage frequency and household dust levels. Regular maintenance ensures optimal suction power and prevents motor strain from clogged components.

Does it work well with pet hair?

The Roomba 681 handles pet hair reasonably well on hard floors and low-pile carpets. The side brush helps gather hair from corners and edges, whilst the main brush system collects it effectively. However, long pet hair may occasionally wrap around the brushes, requiring manual removal during routine maintenance.

How loud is the Roomba 681 during operation?

The noise level measures 78 decibels, which is comparable to a washing machine or dishwasher. Whilst not silent, it's quiet enough for daytime use without significantly disrupting conversations. Many users avoid running it during evening hours to prevent disturbing neighbours or sleeping family members.

Can I schedule cleaning times through the app?

The Roomba 681 includes application control functionality, allowing remote operation through your smartphone. You can start and stop cleaning cycles remotely, though advanced scheduling features may be limited compared to higher-end models. Check the specific app capabilities for detailed scheduling options available with this model.

What happens if it gets stuck or encounters obstacles?

Built-in sensors help the robot navigate around furniture and detect drop-offs like stairs. If it becomes stuck under furniture or encounters cables, it will attempt to reverse and find an alternative route. However, it's recommended to clear loose cables and small objects before cleaning to prevent entanglement or damage.

How does it find its way back to the charging station?

The robot uses infrared sensors to locate and dock with its charging base automatically. When battery levels drop to approximately 20%, it begins searching for the charging station. The base should be placed against a wall with clear access from the front to ensure reliable docking every time.
