Two cordless robotic pool vacuums, one clear winner. I put the Beatbot AquaSense 2 and the ECOVACS Ultramarine P1 through their paces, and while both do a solid job cleaning floors, walls, and waterlines, they are not equal. One has a longer battery, smarter navigation, and a warranty that frankly embarrasses the competition.
If you want the short answer: the Beatbot AquaSense 2 is the better buy for most pool owners. But the ECOVACS Ultramarine P1 earns its place too, especially if your pool is on the smaller side. Here is everything you need to know before you spend your money.
π Our #1 pick: Beatbot AquaSense 2. The Beatbot AquaSense 2 wins on runtime, waterline cleaning, navigation smarts, and a 3-year full replacement warranty that no competitor currently matches. Check price β
1. Beatbot AquaSense 2, Best Overall
The Beatbot AquaSense 2 is a really sweet little robot pool vacuum, and after getting it into my pool I can see why it stands above the crowd. Right off the bat, the design tells you this thing means business. It runs dual front and back roller brushes that keep working the whole time it is moving, whether it is on the floor, climbing the walls, or scrubbing the waterline. The bulldozer-style tires are built to handle depth changes and wall climbing without fuss, and there is an edge-detection solution built in that keeps the unit from banging into pool walls and needing to redirect constantly. That is something I have not seen executed this cleanly on other robots.
The debris basket is simple, an open design you just pull out when you want to clean it. Nothing complicated there. The real standout is the cleaning coverage. The AquaSense 2 runs on an optimized S-path for floors and an N-path for walls and the waterline, driven by a 4-core CPU and 16 sensors including two ultrasonic sensors. I set it to the floor, wall, and waterline mode in the app and watched it work systematically rather than wandering around randomly.
Battery life is a genuine advantage here. The battery delivers up to 4 hours of floor cleaning or 3.5 hours of wall and waterline scrubbing, covering pools up to 3,230 sq ft. That is a meaningful edge over most competitors. One thing worth noting is that after you drop it in, give it about 2 minutes before it kicks into gear. That is normal, not a defect.
The double-pass waterline scrubbing is legitimately useful. Instead of one pass like most robots, the AquaSense 2 hits the waterline twice per pass, which makes a real difference on stubborn grime and buildup. The app also has an eco mode that cleans every 48 hours automatically, which is perfect if you are heading out of town.
Auto surface parking is another feature I appreciate. When the battery gets low or the cleaning cycle ends, it parks above the waterline on its own. SmartDrain releases the water so you are not wrestling a waterlogged unit out of the pool. And the wireless charging dock means no exposed ports, no cords tangled around a wet robot. The 3-year full machine replacement warranty, not a repair warranty but an actual replacement, is an industry-first and gives real peace of mind.
- Double-pass waterline scrubbing for deeper clean
- Up to 4 hours of runtime on a single charge
- Auto surface parking and SmartDrain for easy retrieval
- 3-year full machine replacement warranty
π Pros
- Up to 4 hours of runtime, covers pools up to 3,230 sq ft
- Double-pass waterline scrubbing goes deeper than single-pass robots
- Auto surface parking and SmartDrain make retrieval effortless
- 3-year full machine replacement warranty is industry-leading
π Cons
- Takes about 2 minutes after submersion before it starts cleaning
- Premium feature set comes at a higher price point
π The AquaSense 2 is the most capable cordless pool robot I have tested, with longer battery life, smarter navigation, and a warranty that is genuinely unmatched.
2. ECOVACS Ultramarine P1, Best for Smaller Pools
The ECOVACS Ultramarine P1 is a first for ECOVACS, a brand you probably know from their robotic lawnmowers. They are new to the pool cleaning space, and for a debut product, the Ultramarine P1 is more capable than I expected. That said, there are real limits here that are worth understanding before you buy.
Like the Beatbot, the Ultramarine P1 runs on bulldozer-style tires that handle wall climbing and depth changes well. I found it navigates depth transitions smoothly, and for inground pools with a drain on the bottom, it handles drains up to two and a quarter inches without getting stuck. The front and back roller brushes run continuously, pushing debris into the internal basket the entire time the unit is moving.
The filtration setup is legitimately impressive. A dual-layer system pairs a mesh filter with an ultra-fine filter. The motor and battery are rated for long-term underwater use.
Battery is where you feel the gap versus the Beatbot. The battery delivers up to 180 minutes of runtime, and that 3-hour ceiling is only achievable in floor-only mode with eco suction selected. Switch to wall cleaning or crank up to strong suction and the battery drains faster. The coverage ceiling is also 1,937 sq ft, meaningful if your pool is on the smaller side but limiting for larger setups.
The app gives you three suction settings, eco, standard, and strong, and three cleaning modes: floor only, wall only, and a combined full-pool mode. That level of control is useful. SmartNavi technology uses IMU-powered mapping to reduce missed spots.
For a brand making its first pool robot, the Ultramarine P1 is a respectable entry. If your pool is under 1,937 sq ft and you want solid filtration with app control, it competes. For larger pools or anyone who wants the best waterline scrubbing and the longest runtime, the Beatbot wins.
- Dual-layer filtration for effective debris capture
- Three suction modes and three cleaning modes via the app
- Motor and battery rated for durable underwater operation
π Pros
- Dual-layer filtration is thorough
- Three suction levels give you real control over battery trade-offs
- Handles inground pool drains up to 2.25 inches without snagging
- Motor and battery built for long-term reliability
π Cons
- 180-minute max runtime is only achievable in floor mode with eco suction
- Coverage limited to pools up to 1,937 sq ft
- First-generation pool product from a brand new to this category
π The Ultramarine P1 is a solid debut from ECOVACS with effective filtration, but shorter runtime and smaller pool coverage hold it back from the top spot.

The bottom line
Both of these robots beat manually vacuuming your pool without question. But if you want the best performance available in a cordless pool robot right now, the Beatbot AquaSense 2 is the one to get. Longer battery, double-pass waterline scrubbing, auto surface parking, and that industry-first 3-year replacement warranty make it the clear top pick.
