Head-to-head

Hayward TigerShark QC vs Dolphin Nautilus CC Supreme: Both offer 90-minute cycles, Dolphin adds top-access filters

The short answer

Choose TigerShark QC for control-box operation and lower dry weight in a pool up to 20 by 40 feet. Choose Nautilus CC Supreme for app scheduling, top-access filters and a pool up to 50 feet. Both offer a 90-minute option, so the Quick Clean name alone does not make Hayward faster.

About this comparison

What matters in practice

The differences that matter

Quick Clean is not unique to Hayward

Both offer a 90-minute option.

How we reached this conclusion

Supreme's 1.5 hours × 60 = 90 minutes. Equivalent duration does not prove equivalent cleaning coverage.

Top access can matter more than three pounds

Supreme avoids the bottom-lid step but weighs more dry.

How we reached this conclusion

Hayward requires placing the cleaner on its side to remove the filter lid. Supreme lists top access. 24.63 − 21.5 = 3.13 lb.

Width is a separate Hayward limit

A pool can be short enough and still exceed the rated width.

How we reached this conclusion

The published envelope is 20 × 40 ft. A 22 × 38 ft pool exceeds that width despite staying under 40 ft long.

What you give up

Every choice has a cost

If you choose Hayward TigerShark QC

  • The 20 × 40 ft envelope is restrictive

If you choose Dolphin Nautilus CC Supreme

  • Connected setup does not remove filter cleaning and retrieval

Recommendation switch

The decision flips if...

The pool exceeds 20 feet wide or 40 feet long

Choose Dolphin Nautilus CC Supreme. TigerShark is outside its envelope. Confirm Supreme's complete pool compatibility.

App schedules are essential

Choose Dolphin Nautilus CC Supreme. Supreme supplies the required connected controls.

Local controls and lower dry weight matter in a suitable pool

Choose Hayward TigerShark QC. TigerShark matches that routine.

What matters in practice

How to make the call

01

Check both pool dimensions

Hayward specifies a 20 by 40 ft envelope. Omitting width can create a false match. Supreme gives a 50-foot length rating, which still needs checking against the pool's shape and surface.

02

Choose a maintenance posture

TigerShark is lighter, but the filter comes out through the bottom after turning it on its side. Supreme is heavier with top access. Consider the action repeated after each run rather than weight alone.

03

Read cycle names carefully

Both offer 90 minutes. Hayward describes Quick Clean as treating the main pool area, while the full cycle is about four hours. Different full-cycle durations do not establish which machine completes the same job better or faster.

Check these before buying

  • Confirm RC9990CUB Quick Clean rather than RC9950 or a remote-equipped variant.
  • For tile, check whether the optional foam roller is required.
  • Check both pool dimensions, retrieval access and filter contents.
  • Do not treat a 90-minute mode as guaranteed full-surface coverage.

What this comparison cannot tell you

  • No equal-condition coverage or speed test was performed. Dry weights exclude retained water.
