Dyson Big Ball Allergy Reviews

Formerly known as the DC65, Dyson claims that the Ball Allergy is 25 percent more powerful than what came before it -- but does that translate to performance?

The ; (formerly known as the DC65 Animal) vacuums even better on carpets than the DC41 that came before it, with improved airflow and a more powerful brushroll.

Annoying design issues that plagued the usability of the DC41 linger through to the Ball Allergy. Most notably, the vacuum clicks into its upright position, but it doesn't always stick and can come crashing to the floor.

The DC41's design disappointed us, and the Ball Allergy's isn't any better. Despite the strong performance scores, this pricey Dyson is still difficult to recommend.
