Some customers praise its job and quality, while others describe little or no suction, weak cleaning power and concerns about it breaking quickly. For buyers relying on the listed gravel-cleaning and siphoning functions, the performance concerns matter. Overall ratings are mixed, so they do not establish consistent results for an individual unit.
