The front and rear scrubbers attack grime head-on, while the large filtration basket traps leaves, sand, and fine debris in one go—delivering a spa-like finish on a tight budget.
In real-world use, the Crab proves surprisingly capable, running for over 90 minutes on a full charge and covering floors and walls with consistent, overlapping passes. It handles vinyl and fiberglass pools with ease, though it occasionally misses tight corners and may require a second cycle for heavily soiled areas. The cordless design makes retrieval simple—just hook it with the included pole—while the detachable impeller prevents hair clogs, a common pain point in lower-tier models. However, it lacks app control or smart navigation, relying on random pathing, which means coverage isn’t as thorough as premium bots.
For cost-conscious buyers, the Seauto Crab is the best value in budget robotic cleaning, especially for smaller to mid-sized pools. It’s significantly more capable than manual vacuums and even outperforms some higher-priced models in suction strength. When stacked against the Dolphin Nautilus CC, it offers stronger suction and lighter weight but sacrifices runtime, smart navigation, and waterline cleaning. If your priority is lightweight design and powerful suction without the premium tag, the Seauto Crab is a no-brainer.

Choosing the Right Robotic Pool Vacuum: A Buyer’s Guide
Pool Size and Cleaning Capacity
The size of your pool is the most important factor when selecting a robotic pool vacuum. Smaller pools (under 1,500 sq. ft.) can often be effectively cleaned by more affordable models with shorter run times. Larger pools (over 3,000 sq. ft.) demand robots with longer battery life (3+ hours) and potentially higher suction power to complete a full cleaning cycle. Pay close attention to the manufacturer’s stated coverage area; a robot rated for 3,200 sq. ft. will likely struggle in a 4,000 sq. ft. pool. A robot that can’t complete the cleaning in one cycle will leave debris behind, defeating the purpose.
Navigation and Pool Shape
Robotic pool vacuums employ different navigation systems. Basic models may use random patterns, which can be less efficient and may miss spots. More advanced robots, like the Beatbot AquaSense 2, utilize intelligent path optimization (e.g., CleverNav) with sensors to map your pool’s shape and create systematic cleaning routes (S-path for floors, N-path for walls). This is especially crucial for irregularly shaped pools or those with many obstacles. Consider whether the robot can handle the specific contours of your pool – some excel at climbing walls, while others focus primarily on the floor.
Cleaning Features: Scrubbing and Filtration
Beyond suction, scrubbing is a key feature for removing stubborn dirt and algae. Some robots, like the Dolphin Nautilus CC, feature active scrubbing brushes that provide a more aggressive clean. The Beatbot AquaSense 2 takes this a step further with double-pass waterline scrubbing. The quality of the filtration system is equally important. Look for robots with easily accessible and cleanable filter baskets or cartridges. Filter fineness determines what size debris the robot can capture; finer filters catch more particles but may require more frequent cleaning. A larger filter capacity means less frequent emptying.
Corded vs. Cordless Operation
Traditionally, robotic pool vacuums were corded, which could be cumbersome to manage. Newer models, like the Beatbot AquaSense 2 and Seauto Crab, offer cordless operation. This provides greater freedom of movement and eliminates the risk of tangled cords. Cordless robots typically come with a charging dock and can often return to the dock automatically when the battery is low. However, cordless models rely on battery life, so a longer run time is essential for larger pools.
Additional Features to Consider
- Wall Climbing: Essential for cleaning pool walls.
- Waterline Cleaning: Important for removing grime buildup.
- Smart App Control: Allows remote control and scheduling.
- Obstacle Avoidance: Prevents the robot from getting stuck.
- Warranty: A longer warranty provides peace of mind and protects your investment.
- Weight and Ease of Handling: Particularly important for frequent removal from the pool.
- IMR Coating: Protects the robot from sun and chemical exposure.
The Bottom Line
Choosing the best robotic pool vacuum ultimately depends on your specific needs and pool type, as highlighted in our guide. From budget-friendly options like the Seauto Crab to feature-rich models like the Beatbot AquaSense 2, there’s a robot to simplify pool maintenance for every owner.
Considering factors like pool size, shape, and desired cleaning features will ensure a smart investment. By carefully evaluating these aspects, you can enjoy a cleaner pool with less effort, leaving you more time to relax and enjoy the summer!
