Performance Face-Off
Cleaning on Hardwood Floors
The Shark IQ Robot UR1000SR generally performs better on hardwood floors due to its strong suction and efficient brush design. It effectively picks up dust, dirt, and debris, leaving floors clean and polished.

Cleaning on Carpets

The Roomba i4’s Power-Lifting Suction and Dual Multi-Surface Rubber Brushes work together to agitate and lift dirt and pet hair from carpet fibers. While the Shark IQ Robot UR1000SR can handle low-pile carpets adequately, it may struggle with deep cleaning on thicker carpets.
Pet Hair
Both the Shark IQ Robot UR1000SR and the Roomba i4 are designed to handle pet hair, but the Roomba i4’s tangle-free brush design gives it a slight edge. The Roomba i4’s Dual Multi-Surface Rubber Brushes prevent hair from wrapping around the brush roll, making it easier to maintain. The Shark IQ Robot UR1000SR’s self-cleaning brush roll also does a decent job of removing hair, but it may require more frequent cleaning.

The Roomba i4 also offers decent edge cleaning, but it may not be as precise as the Shark IQ Robot UR1000SR in reaching tight corners.
Special Features Comparison

Usability and User Experience
