How We Research
Every guide on Vacuum Critic starts with one question: will this vacuum work for the home it is going into? That depends on your floors, your pets, your stairs and how much you want to carry.
Here is how we answer it.
1. We start with your home
A small apartment with hardwood, a house with wall-to-wall carpet and a home with two shedding dogs each need a different vacuum.
We look at the floor types, the pets and the stairs first. When your home narrows the choice, we say what to look for.
2. We compare specs and features
We look at the vacuum type, weight, cord length or battery runtime, dust cup or bag size, filter type and the brush roll. We also check which tools come in the box.
Shark, Dyson, Bissell, Miele and the others describe their vacuums in their own words, so we name the maker for every claim. We also note the warranty terms they list.
3. We look at buyer feedback
We read what buyers report after using a vacuum. We look for patterns, like brush rolls that tangle, batteries that fade, dust cups that are hard to empty and hoses that clog.
One angry review doesn't sink a product. A pattern does.
4. We score each product
Our score weighs specs, features and buyer feedback against what you're shopping for. A vacuum that is great for one reader may score lower in a guide written for another.
Scores spread out on purpose. A 10 is rare.
5. We keep pages up to date
Makers change models often, and some are sold under near-identical names. So we check each model number, and we only link new units, never used or refurbished ones.
We skip unknown brands with no track record and any vacuum with a known recall. 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.
Suction numbers like air watts and pascals come from the makers and are measured in different ways, so we quote them as the maker's claims. We give no medical advice, and we don't promise a vacuum will help with allergies.
Read the maker's manual before you use any vacuum, and keep cords and batteries away from water unless the vacuum is made for wet use.
