Beatbot AquaSense 2 vs 2 Pro vs 2 Ultra: What Is the Difference?

Last updated: October 2026

The AquaSense 2 cleans the floor, walls and waterline of pools up to 3,230 square feet and charges on a wireless dock. The AquaSense 2 Pro adds surface cleaning and ClearWater clarifying, with a 13,400 mAh battery for pools up to 3,875 square feet. The AquaSense 2 Ultra adds an AI camera, 27 sensors and side brushes that sweep floating debris in. All three carry a 36 month warranty on the main body.

How do they compare?

Every figure is Beatbot's. Where Beatbot's listing for a model does not give a figure, the table says so.

Beatbot describes the 5,500 GPH figure as the highest rate in its lab tests.

What do all three share?

• Floor, walls and waterline cleaning.
• 5,500 GPH suction.
• Ultrasonic sensing for route planning and obstacle avoidance.
• Surface parking so the robot is easier to lift out.
• 36 months of warranty on the main body.

What does the AquaSense 2 do?

The Beatbot AquaSense 2 is the three-zone model.

• Floor, walls and waterline, with two scrubbing passes along the waterline.
• Parks at the surface when done or low on battery, then releases its water so it is lighter to lift.
• Wireless charging dock: set the robot on it. There is no plug to connect.
• Up to 4 hours on the floor from a 10,000 mAh battery, recharged in about 4 hours.
• 16 sensors, including two ultrasonic sensors.
• Four guide wheels keep it close to edges and corners.

Suits: a pool up to 3,230 sq ft that does not collect much floating debris, or one that already has a surface skimmer.

What does the AquaSense 2 Pro add?

The Beatbot AquaSense 2 Pro is the four-zone model.

• Surface cleaning on top of waterline, walls and floor.
• ClearWater clarifying. It spreads an agent made from recycled crab shell that binds fine particles so the filter can catch them, per Beatbot. The agent kit is sold separately.
• A larger 13,400 mAh battery: up to 11 hours on the surface, recharged in about 4.5 hours.
• 22 sensors and 9 motors, with ultrasonic mapping and obstacle avoidance.
• App steering on the surface, then tap to park it at the edge.
• Two filter baskets, 3.7 L in total, with 150 μm and 250 μm filtration.
• Recommended for pool floors up to 3,875 sq ft.

Suits: pools with trees, larger pools, and owners who want clearer water without adding clarifier by hand.

What does the AquaSense 2 Ultra add?

The Beatbot AquaSense 2 Ultra adds sight.

• HybridSense: an AI camera combined with infrared and ultrasonic sensors, 27 in all.
• A pool map in the app. After each run you can see the map and the floor cleaning path.
• It goes back for what is left. The camera looks for leaves remaining on the floor and cleans them.
• Two side brushes sweep floating debris toward the intake.
• Four zones plus ClearWater clarifying. The agent kit is sold separately.
• Up to 10 hours on the surface or 5 hours on the floor from a 13,400 mAh battery.
• 11 motors.

Suits: owners who want to check the work, pools with irregular shapes, and heavy leaf fall where a second look at the floor pays off.

What is ClearWater, and do you need it?

It is a clarifier dispenser built into the robot. A clarifier makes tiny suspended particles clump together so filters can remove them, which is how cloudy water turns clear. Beatbot's agent is made from recycled crab shell.

You need it if your water often looks dull despite balanced chemistry, or if you already use a clarifier. You do not need it if your water stays clear. It does not sanitize and is not an algaecide. See do robotic pool cleaners clean algae?

Is surface cleaning worth it?

If you net the pool often, yes. Floating leaves that are removed never reach the floor. The 2 Pro and 2 Ultra spend up to 10 or 11 hours skimming on a charge. If your pool sits in the open and stays clear on top, the AquaSense 2 covers what you need. See do robotic pool cleaners pick up leaves?

What does the camera change?

Robots without a camera follow a planned pattern and trust it. A camera lets the Ultra confirm what is on the floor and return for leaves that were missed or that sank mid-cycle. The app map also shows you where it went, which helps if one corner keeps being missed.

Where does the original AquaSense fit?

The first-generation Beatbot AquaSense is still available. Per Beatbot it is recommended for pool floors up to 2,260 sq ft, with 5,500 GPH suction, 15 sensors and a 2 L top-access basket, and a 24 month warranty on the main body. It suits smaller pools.

Where does the AquaSense X fit?

Above all of them. The Beatbot AquaSense X comes with the AstroRinse station, which rinses the filter and empties the debris in about 3 minutes into a 22 L bin. Beatbot says the bin can go up to 2 months between emptying. It cleans five zones: surface, waterline, walls, floor and shallow platforms at least 13.7 inches deep. Choose it if emptying and rinsing a basket is the part you want gone.

Which one for which pool?

AquaSense or Sora?

Beatbot's Sora line has higher rated suction (6,800 GPH) and larger baskets. AquaSense has more sensors, wireless docks and clarifying. See Beatbot Sora 10 vs 30 vs 70.

What about shipping and warranty?

Beatbot ships your order, normally within 48 hours, with an average transit of 3 to 7 business days, per its shipping policy. It does not ship to Alaska, Hawaii, US territories or military post boxes. Shipping cost is shown at checkout.

Beatbot covers the main body for 36 months on the AquaSense 2, 2 Pro and 2 Ultra in the United States, from the date of purchase. Filter baskets and roller brushes are covered for 3 months.

What is the short answer?

Three zones: AquaSense 2. Four zones and clearer water: 2 Pro. Four zones, a camera and a map: 2 Ultra.
