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.
