Beatbot AquaSense 2, the heavy cordless one
Beatbot's AquaSense 2 parks on the surface, scrubs the waterline twice, and carries a long review trail. Here is who that weight is for.
Buy the AquaSense 2 when the pool is large, you care about the waterline, and you want a robot that waits on the surface instead of dying on the floor. Skip it if you need a machine a smaller person can lift every day, or if mixed owner reports on suction make you nervous.

What holds up
- Parks at the surface and drains itself, which is the least annoying retrieval in this group
- Double-pass waterline scrub and side guide wheels for edges
- Long stated runtime and a large coverage number
- Three-year replacement coverage is the longest warranty here
- Hundreds of owner ratings, so the failure modes are public
What to doubt
- About 27 pounds before it is full of water. Retrieval is easier, lifting is not
- Owners disagree on whether it picks up fine debris and whether the battery lasts the brochure time
- Wall climbing is praised and criticized in the same review set
- You are paying for the dock, the sensors, and the warranty, not for a simple drop-in brick
The retrieval trick is the product
Most cordless robots end the cycle on the floor. You fish with a hook, or you swim. The AquaSense 2 is built to park above the water when the cycle ends or the battery drops, then dump the water in its float chamber so the lift is lighter. There is also an app park command while it is still on the surface. That is the feature people are actually buying.
The rest of the spec supports a big pool: a 10,000 mAh pack, a claim of up to four hours on the floor or about three and a half on walls, and coverage up to 3,230 square feet. CleverNav uses a 4-core controller and 16 sensors, including two ultrasonic, with an S-path on the floor and an N-path on the walls. Four side guide wheels are there to hold the edge and the corners.
What owners argue about
The review set is large enough to trust the disagreement. Plenty of people say setup is easy and the floor comes back clean. A sizable minority say it misses debris, finishes early, or does not climb. Both can be true. A packed basket, a slimy waterline, or a low charge will make a sensor-heavy robot look broken. A pool with a complicated bench will expose the climbing limit no brochure erases.
Charge it on the wireless dock, fully, before the first swim-week. The dock is also the storage plan: no exposed port sitting in a puddle. Keep the basket rinsed. If it will not climb, do not start with a warranty claim. Confirm the mode includes walls, the waterline is not greased over, and the battery is not already in the reserve that triggers parking.
How it sits next to the SAT25
The OYEMIA SAT25 is lighter to own and narrower in ambition: push-button, 180 minutes, 2,150 square feet, 300 micron basket, one-year coverage, little review history. The AquaSense 2 is the opposite shape. Choose Beatbot when retrieval and waterline passes are the pain. Choose the SAT25 when the pool is ordinary and you want fewer parts.
Questions before you buy
Does the AquaSense 2 sink on its own?
It is designed to dive and clean, then return to the surface to park. If it never sinks, check for trapped air, a mode that is already in park, or a battery too low to start a cycle. The won't-sink guide walks through those checks.
Can it do above-ground pools?
Beatbot lists above-ground and inground pools, including concrete, tile, vinyl, and fiberglass, up to the coverage figure. Soft, wrinkled liners and very shallow beaches are still hard for any robot.
