- CyberShack (8.7/10): Excellent hard floor vacuuming at 91% to 95% and good mopping close to skirting, above average on short and medium pile carpet, but weak on carpet pet hair and no edge or corner cleaning on carpet. Measured 100 to 125 minutes of real runtime. Source

- Tom's Guide: On hardwood it picked up 92% hair, 94.5% puffed rice and 98% flax seeds. On high pile carpet it got 40% hair and 38.5% flax seeds. About 55 dB mopping and 60 dB vacuuming. Called it ideal for hardwood homes. Source
