Main trade-off
Roborock H60 Hub Ultra
TechRadar recorded about 25 minutes in medium mode, far below the 90-minute maximum claim.
Head-to-head
Roborock is the cleaner emptying choice because its dock uses a sealed bag and its battery detaches. Shark is the more adaptive floor cleaner and the clear winner under low furniture.
Before you choose
Only Shark PowerDetect Clean & Empty System has a positive checked result for “Automatic suction” in this pair. If it is required, the decision is already made.
What this is based on
The conclusion follows the checked yes or no difference for the exact configurations compared.
Main trade-off
TechRadar recorded about 25 minutes in medium mode, far below the 90-minute maximum claim.
Main trade-off
The near-eight-pound stick is heavier than most docked rivals.


Two current auto-empty sticks split on bagged containment, automatic sensing and folding reach.
The practical choice turns on dock and maximum runtime claim, then on the constraints in your own setup.
Before you choose
Shark documents a Quiet switch that defers IP3251's dock emptying while the vacuum charges. That is useful if the dock sits beside a desk and a quick cleanup ends during a meeting. The reviewed H60 evidence establishes its bagged station but no equivalent delay control here. Choose Shark if that verified manual control is essential, or place either dock where an emptying cycle will not interrupt occupied rooms.
This compares a documented control with an evidence gap, not measured noise levels. Do not infer that Roborock cannot defer emptying, or that Shark's switch makes normal vacuuming quieter.
If you want one chosen suction setting throughout a familiar hard-floor room, H60's manual power selection is a straightforward fit. IP3251 adjusts suction using its floor and dirt sensing, which is useful when one pass crosses changing debris and surfaces. Choose Shark for fewer manual adjustments. Choose H60 when deliberate mode control matters more, while reserving extra time or battery for heavier debris.
Automatic changes are a convenience difference, not evidence of better pickup or quieter running. The reviewed headline runtimes do not quantify the duration or sound of each model during this changing-load scenario.
Winner by situation
For maximum runtime claim, Roborock H60 Hub Ultra records “Up to 90 minutes” and Shark PowerDetect Clean & Empty System records “Up to 70 minutes”. This changes how much work fits into one session before charging or swapping batteries.
Its documented sealed filtration better contains fine particles and exhaust dust.
Its station transfers debris into a sealed disposable bag.
For automatic suction, Roborock H60 Hub Ultra records “No” and Shark PowerDetect Clean & Empty System records “Yes”. The published output matters only when the room, surface or workload needs the extra headroom. It does not prove better results by itself.
For low-reach wand, Roborock H60 Hub Ultra records “Straight telescopic” and Shark PowerDetect Clean & Empty System records “Folding MultiFLEX”. This affects working reach and where the main unit or power source must stay during use.
Its larger onboard bin or high-capacity dock stretches time between emptying.
What matters in practice
Only Shark PowerDetect Clean & Empty System has a positive checked result for “Automatic suction” in this pair. If it is required, the decision is already made.
The conclusion follows the checked yes or no difference for the exact configurations compared.

Roborock, H9A1A
A high-output stick with a detachable battery, green floor light and compact three-liter bagged dock.

Shark, IP3251
A flexible-wand Shark that cleans in both directions and parks on a high-capacity bagless auto-empty dock.
Meaningful differences
| What changes | Roborock H60 Hub Ultra | Shark PowerDetect Clean & Empty System | Why it matters |
|---|---|---|---|
| Dock | Three-liter disposable bag | Two-liter bagless canister | The dock can change floor-space needs and the charging, emptying or cleaning work done after each session. |
| Maximum runtime claim | Up to 90 minutes | Up to 70 minutes | This changes how much work fits into one session before charging or swapping batteries. |
| Automatic suction | No | Yes | The published output matters only when the room, surface or workload needs the extra headroom. It does not prove better results by itself. |
| Low-reach wand | Straight telescopic | Folding MultiFLEX | This affects working reach and where the main unit or power source must stay during use. |
