Performance Face-Off
Bare Floor Cleaning
The Roborock S4 excels on bare floors, effectively picking up almost all debris, including hair, dust, and small particles. Its strong suction and efficient cleaning path ensure a thorough clean. The Shark IQ performs well on bare floors but may struggle with larger debris as the dirt compartment fills up.
Low-Pile Carpet Cleaning
The Shark IQ demonstrates decent performance on low-pile carpets, handling medium and large debris effectively. However, it may leave behind some fine debris, such as sand. The Roborock S4 also performs well on low-pile carpets, though some tests show it can struggle with fine debris like baking soda.
High-Pile Carpet Cleaning
The Shark IQ is a decent choice for cleaning high-pile carpets, capable of clearing most debris. It may struggle along walls and corners, which is common for circular robot vacuums. The Roborock S4 Max has the ability to maneuver on high-pile carpets, but the Roborock S4 is not designed for high-pile carpets.
Pet Hair Cleaning
Both robot vacuums are satisfactory choices for dealing with pet hair. The Shark IQ features a self-cleaning brushroll, which reduces the risk of hair wraps. The Roborock S4 effectively picks up pet hair from both bare floors and low-pile carpets.

Maintenance and Longevity

Maintaining the Shark IQ Robot Vacuum involves regular cleaning of the brushroll and occasional replacement of the filter. The self-emptying base reduces the frequency of dustbin emptying.
