Here’s the side by side comparison to help you buy the better one that meets your cleaning needs.
Design
The Rowenta Delta Force works like a traditional stick vacuum, while the Dyson DC44 Animal can be transformed from a cordless stick to a handheld vacuum by
removing its wand and cleaner head. And you can use it with the wand attached to clean high and low spots. While the Rowenta Delta Force does not have the
cleaning wand and its cleaner head is not detachable.
Charging Time
The DC44 charge faster, takes a lot less time to fully charge.
Run Time
The Rowenta Delta Force has a longer battery life than the Dyson DC44.
Charging Base
The DC44 comes with a docking station for charging and storing while the Rowenta Delta Force has no charging stand.
Attachments
The DC44 comes with some attachments for cleaning upholstery, crevice, corners, etc. While the Rowenta Delta Force does not include such tools.
Cost
The DC44 is much more expensive, about 2X the cost of the Rowenta Delta Force.
Self Stand
Both of them are not the types that can stand up by their own securely. Rowenta Delta Force can stand free, but not stable, easily topple over. While the Dyson DC44
cannot self stand at all, and does not even let you lean it against a wall, it can easily fall down.
Dust Cup Capacity
The dust cup on the Rowenta Delta Force is larger.
Weight
The DC44 weighs around 2 pounds lighter
Battery Replacement
You can easily replace battery on DC44 while the batteries on Rowenta is not designed for you to replace.
On/Off Control
The Rowenta use traditional On/Off switch while the Dyson DC44 uses a Trigger instead of an On/Off switch. The key difference between this trigger design and a tradition switch is that the trigger does not lock into place, you have to keep pressing the trigger if you want the vacuum on. Dyson claim that this reduce wasted energy. Well, we do not know how much energy it saves, some people like it, but others hate it because their fingers get tired of holding the trigger down.
