There are many key factors we look at when helping you decide on a Dyson vacuum. Here are some of the ones we use to weigh scoring.

Cordless vs. corded
Cordless Dyson models (V-series, Gen5) prioritize portability for quick cleanups and multi-level homes but are limited by battery life. Generally, CNET only tests cordless vacuums in our testing lab, but that doesn't mean corded isn't the right choice. Our lab testing shows that most Dyson vacuums we recommend can last between 30-60 minutes on a single charge, depending on the mode you're using them on. In contrast, corded models like the Dyson Ball Animal 3 and Dyson Big Ball Turbinehead deliver uninterrupted, max-power cleaning for deep carpet sessions or large areas, though they sacrifice maneuverability and weigh significantly more when accounting for the canister. Cordless vacuums are a good option for apartments or spot cleaning, while corded ones are good for whole-home deep cleans.
Battery life
We touched on this earlier, but battery performance varies drastically by mode. Eco Mode (50–85 mins) handles light dusting on hard floors, Auto Mode (30–45 mins), available on some models, automatically adjusts suction to accommodate mixed surfaces. Boost Mode or Max Mode is the highest suction setting for major messes, but it'll drain the fastest (10-15 minutes). This makes it ideal for high-pile carpets or ground-in dirt. Models like the Gen5 Outsize include dual batteries, extending runtime to 140 minutes in Eco mode, but add significant weight at 8.6 pounds. Recharging also takes more than four hours after full depletion, so it's not the best option for a quick cleaning session.
Suction
Measured in Air Watts (AW) suction is a measure of how effectively the vacuum can remove dirt from various surfaces. While the Gen5 Detect’s 262 AW excels on embedded carpet dirt, the V8’s 115 AW suffices for small spaces or hard floors.
