iRobot Roomba i4 EVO
Score: 80/100
Mamnv Robot Vacuum
Score: 69/100Rankings
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 MAMNV BR151 is a budget-friendly 2-in-1 robot vacuum-mop offering 1400 Pa suction, a 100-minute runtime and 3D obstacle avoidance, making it capable for pet hair on hard floors and low-pile carpet. Its limitations include modest suction power, a small dustbin and non-systematic cleaning paths that may miss areas. Ideal for small-to-medium homes where price and basic functionality outweigh advanced mapping needs.

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.
“intuitive and easy”
Professional commentary, though limited to a single blog post, views the BR151 as a capable entry-level robot for hard floors, noting its effective 1400 Pa suction, convenient 2-in-1 vacuum-mop design, and solid obstacle avoidance, while criticizing the lack of advanced mapping and the scarcity of thorough testing.
Everyday users appear to value the robot's pet-hair handling, quiet operation, and easy app scheduling, but they commonly mention the need to empty the small dustbin frequently and occasional navigation hiccups on obstacles.
