How We Research
Every guide on Post Fifty answers one question: will this upright suit your floors, your pets and the way you clean? A vacuum that shines on low carpet can be the wrong pick for thick rugs or a house full of hard floors.
Here is how we work it out.
1. We start with your home
We look at the floors the guide is about: thick carpet, low-pile carpet, hardwood, tile or a mix. We also think about pets, stairs and how far the vacuum has to travel from the outlet.
That tells us which features matter most, and we say what to check before you buy.
2. We compare specs and design
We compare the weight, cord length, cleaning path, height settings and brush roll type. We check whether the vacuum uses bags or a bin, and what kind of filter it has.
We also look at the tools, the hose reach and features like Lift-Away pods, swivel steering and a brush roll shut-off for hard floors.
Makers describe their vacuums in their own words, so we name the brand for every claim. We also note the warranty terms the maker lists.
3. We read what owners report
We go through what owners say after real use. We look for patterns like hair wrapping on the brush roll, belts that wear fast, clogs, loose parts and vacuums that feel heavy on carpet.
One bad report doesn't sink a vacuum. A pattern does.
4. We score each vacuum
Our score weighs specs, features and owner feedback against what you're shopping for. The same upright can score well in one guide and lower in another, because the home is different.
Scores spread out on purpose. A 10 is rare.
5. We check recalls and keep pages current
We check new picks against public recall lists from the CPSC and leave out models with a known recall. We only link new units, never renewed or used ones.
Models change and some disappear. When we update a guide, the "Updated on" date at the top changes with it.
What our picks are not
Our picks are research, not lab tests. We don't claim to have used every vacuum we cover.
We don't make health claims. If a maker rates a filter a certain way, we say the maker says so.
Your vacuum's manual decides how to use, empty and clean it.
