Eureka Optima 431F Review
The Eureka Optima 431F may be tiny, but... but nothing. It's just tiny.
Fibber McGee. Oscar the Grouch. Oscar Madison. This is a partial list of folks who would appreciate the 431F’s lack of cleaning prowess. Most people looking to clean their home should look elsewhere, as the poor Eureka ignored most of the dirt we put down on carpets — though it did do an adequate job on wood floors.
Dirt & Debris Cleaning
Stick to hardwood floors and small debris.
Each time we test a vacuum’s performance on carpet, we first put down 100g of test dirt. More than 94g of dirt remained when the Optima was through on our long carpet test. It’s almost as if we didn’t even vacuum. On short carpet it did a little better—picking up 12% of the dirt we put down—but not well enough for us to recommend it. Only on wood floors did the Eureka Optima 431F perform fairly well, picking up 82%.
It also did poorly on our pet hair test. Most of the hair we put down got blown around by the powered brushroll, the rest ending up stuck on the roller or clogged in the filter. In our debris pickup tests, the vacuum had real trouble with larger items, picking up none of the coins we put down. On carpet, it had trouble with large, dried pasta pieces. However, on both wood floors and carpet, it cleaned up nearly all the rice we left.
Noise & Energy
Unexpectedly loud and hungry for its size
We measured the high-pitched whine emanating from this cleaner at 77.83 decibels. That’s above average, and among the highest we’ve seen for a compact. As far as energy consumption is concerned, with the brushroll turned on, the 431F used a whopping 1345 watts. With its subpar carpet cleaning performance, one could argue that all of it was a waste of energy.
