Robot Vacuum Specs Compared: Suction (Pa), Bin Size, and Battery Reference

2026.06.22

This reference page provides a technical comparison of suction pressure, internal dustbin capacity, and battery specifications for leading robot vacuum models released between 2023 and 2026. It is designed as a data resource for comparing standardized manufacturer specifications across different hardware ecosystems.

Technical Definitions

Suction (Pa)
Measured in Pascals (Pa), this represents the atmospheric pressure difference the vacuum motor generates. Higher values indicate a greater theoretical ability to lift debris, though actual pickup is also influenced by brush roll design and airflow (CFM).
Bin Size (ml)
The volume of the internal dust container measured in milliliters (ml). For models with "Auto-Empty" stations, this refers specifically to the onboard storage before a dock evacuation cycle is required.
Battery Capacity (mAh)
Measured in Milliampere-hours (mAh), this indicates the total energy charge the battery can hold. This figure correlates with maximum runtime, typically measured in "Quiet" or "Standard" modes.

Specifications Comparison Table

The following table aggregates manufacturer-reported specifications for flagship and mid-range models. Note that suction figures represent the maximum "Boost" or "Max+" settings.

Model Max Suction (Pa) Internal Bin (ml) Battery (mAh)
Ecovacs DEEBOT X5 Pro Omni 12,800 [1] 250 [1] 6,400 [1]
Dreame X40 Ultra 12,000 [2] 300 [2] 6,400 [2]
Roborock S8 MaxV Ultra 10,000 [3] 270 [3] 5,200 [3]
Roborock Qrevo Master 10,000 [4] 220 [4] 5,200 [4]
Narwal Freo X Ultra 8,200 [5] 1,000 (HEPA Bag)* [5] 5,200 [5]
Eufy X10 Pro Omni 8,000 [7] 330 [7] 5,200 [7]
Dreame L20 Ultra 7,000 [8] 350 [8] 6,400 [8]

*Note: The Narwal Freo X Ultra utilizes a high-capacity disposable HEPA dust bag within the robot itself, differing from the standard plastic bins used by competitors.

Measurement Variances and Standards

While Pascal (Pa) is the industry standard for marketing suction power, it is important to note that manufacturers measure this at the vacuum motor or the intake port under sealed conditions. Real-world performance may vary based on the distance between the suction inlet and the floor surface.

Battery runtime is typically reported based on the "Quiet" or "Eco" power setting. For example, a 5,200 mAh battery generally provides between 150 and 180 minutes of runtime on the lowest setting [3].

Certain manufacturers, such as iRobot, do not publish Pascal ratings, instead opting for proprietary "Air Power" or "Suction Multiplier" metrics compared to their entry-level models. These models are excluded from the table above to maintain a consistent Pa-based comparison.
