Head-to-head

Dolphin Nautilus AG vs WYBOT B1: AG handles a powered floor-only job, B1 adds walls and waterline

The short answer

Choose Nautilus AG for a powered floor-only routine in a compatible above-ground pool up to 30 feet. Choose WYBOT B1 when documented wall and waterline routes are important and charging is manageable. The B1's 1,150-square-foot area label cannot be converted into a universal pool-length approval, and its two-hour maximum is not a measured cleaning advantage.

Before you choose

The reasoning and the trade-offs

A round-pool area check cannot erase a length limit

A round pool 32 feet across has about 804 square feet of surface area. That is below B1's 1,150-square-foot headline but beyond Nautilus AG's 30-foot length limit. Reject AG for that stated size. B1 remains conditional because surface area alone does not verify its shape, depth, material or above-ground installation requirements. In a compatible smaller pool, coverage and charging are clearer deciding factors.

What this is based on

Pi times 16 squared is about 804 square feet. Diameter is the relevant maximum span in this example. No maximum B1 pool length is invented from its area label.

About this comparison

Compare Dolphin Nautilus AG and WYBOT B1 for above-ground pool sizing, wall and waterline tasks, charging and cleaning-duration claims.

Winner by situation

Start with what you need it to do

  • My round above-ground pool is 32 feet across

    AG exceeds its 30-foot rating. B1 needs full fit verification despite the area being under its headline limit.

  • I need wall and waterline cleaning

    AG is floor-only. B1 documents both additional routes.

What matters in practice

The differences that matter

A round-pool area check cannot erase a length limit

A round pool 32 feet across has about 804 square feet of surface area. That is below B1's 1,150-square-foot headline but beyond Nautilus AG's 30-foot length limit. Reject AG for that stated size. B1 remains conditional because surface area alone does not verify its shape, depth, material or above-ground installation requirements. In a compatible smaller pool, coverage and charging are clearer deciding factors.

How we reached this conclusion

Pi times 16 squared is about 804 square feet. Diameter is the relevant maximum span in this example. No maximum B1 pool length is invented from its area label.

Floor-only maintenance leaves a separate wall task

Nautilus AG's documented job is the pool floor. B1 adds floor, wall and waterline modes, so it is the better starting point when those additional surfaces must be addressed by the robot. Choose AG when a compatible above-ground pool only needs automated floor pickup and a powered setup is convenient. Neither coverage list promises that every liner, curve, slope or contaminant will respond the same way.

How we reached this conclusion

The difference is the manufacturer-supported cleaning role, not a measured debris-removal result. B1's 180-micron filter specification does not quantify how well either machine scrubs residue.

Maximum battery time does not make a scheduled appliance

AG specifies a 90-minute powered cycle and no weekly timer. B1 advertises up to 120 minutes of battery runtime and still needs recharging. Choose AG if eliminating battery charging matters more than cordless use. Choose B1 if cable-free operation and broader coverage justify the charging task. Neither the extra 30-minute headline nor the AG's powered connection establishes unattended multi-day cleaning with no owner care.

How we reached this conclusion

120 minus 90 equals 30 minutes, but maximum endurance and a fixed cycle are different measures. Filter emptying and permitted storage still require owner attention.

What you give up

Every choice has a cost

If you choose Dolphin Nautilus AG

  • The technical table rates pools only up to 30 feet

If you choose WYBOT B1

  • Area alone does not establish shape or material compatibility

Recommendation switch

The decision flips if...

Use a powered 90-minute floor-only cycle

Choose Dolphin Nautilus AG. Avoid charging a battery after its permitted operating period. Floor-only coverage leaves walls and waterline separate.

Add wall and waterline cleaning modes

Choose WYBOT B1. Use cordless operation within the exact pool-fit requirements. Requires recharging.

What matters in practice

Before you choose

Check these before buying

  • Verify the B1 model and pool-material instructions rather than inferring compatibility from area alone.
  • Plan safe cable or charging placement and a realistic retrieval and filter-care routine.

What this comparison cannot tell you

  • No direct cleaning-time, fine-debris pickup or loaded lifting-weight comparison was established.
