Design and Dimensions: 

Both the Roomba 655 and 650 have a similar design with a round shape, making them suitable for navigating around furniture and tight spaces. The Roomba 655 measures 13.4 inches in diameter and 3.6 inches in height, while the Roomba 650 measures 13.39 inches in diameter and 3.62 inches in height. In terms of weight, the Roomba 655 is slightly lighter at 7.9 pounds compared to the Roomba 650, which weighs 8 pounds.

Brushes and Cleaning: 

The Roomba 655 comes with a flat and round brush, offering improved cleaning capabilities compared to the Roomba 650, which only has a flat brush. Both models utilize iAdapt Responsive Navigation technology to navigate and clean floors efficiently. However, the Roomba 655 has a slightly better navigation system and is more effective in cleaning tight spaces and corners.

Battery and Runtime: 

The Roomba 655 features an X-Life NiMH battery, while the Roomba 650 uses an APS NiMH battery. The Roomba 655 has a slightly longer runtime of up to 120 minutes, compared to the Roomba 650’s runtime of up to 110 minutes. Both models take approximately 3 hours to recharge.

Bin Capacity and Filtration: 

Both the Roomba 655 and 650 have similar bin capacities, with a full bin indicator to alert users when it’s time to empty the dustbin. They also utilize AeroVac filtration, which helps capture fine dust particles and allergens during the cleaning process.

Scheduling and Self-Charging: 

The Roomba 655 and 650 offer prescheduled cleaning options, allowing users to set a cleaning schedule up to 7 times per week. Both models are also equipped with a self-charging feature, automatically returning to their charging dock when the battery is low.

Pricing and Value: 

The Roomba 655 is priced higher than the Roomba 650 but offers better cleaning performance and features. Although the Roomba 650 is more affordable, the Roomba 655 provides greater value for those seeking enhanced cleaning efficiency. Consider your needs and budget when making your choice.

Wrap Up:


In a head-to-head Roomba 655 vs 650 review, the Roomba 655 is the better option due to its additional round brush and slightly better navigation system. The Roomba 655 also offers a longer runtime, allowing for more extended cleaning periods. Although it’s priced slightly higher than the Roomba 650, its superior features and performance make it a more desirable choice for most users.
