iRobot Roomba i4 EVO
Score: 80/100
Bissell SpinWave Pet Robot
Score: 78/100Rankings

The Roomba i4 EVO offers LiDAR navigation, strong suction and Alexa voice control in a compact package, making it a solid choice for pet owners in small-to-medium homes. Its main drawbacks are a small dustbin and the absence of a self-emptying base, which can increase maintenance effort. Ideal for users who prioritize precise mapping and compact size over fully hands-free operation.

The Bissell SpinWave 3347 delivers 1500 Pa suction, 130-minute runtime, and dual spinning mop pads for effective pet-hair and wet-floor cleaning. It lacks a self-emptying dock and uses gyroscope navigation, which can be less accurate in complex layouts. Suitable for budget-conscious pet owners with primarily hard floors seeking a combined vacuum-mop solution.

Professional reviewers commend the i4 for its strong hard-floor performance, compact maneuverability, fast charging, and intelligent mapping, noting it outperforms many rivals in navigation and build quality. However, they criticize its inability to handle fine sand, the lack of manual power controls, a small dustbin, and the absence of a self-emptying base in the standard model.
Everyday users love the i4's pet-hair pickup, row-by-row cleaning, easy app and voice control, and its ability to slip under furniture, but they commonly complain about the need to empty the small bin often, occasional missed fine dust, and the higher price compared to models that include a self-emptying base.
