Apart from its powerful suction, the Dyson DC44 Animal also offers a high-capacity dust cup to store all the mess that is sucked up. An easy way to keep the suction level consistent in your vacuum is to keep your bin and cyclone assembly in good condition. Change your HEPA filter
regularly so debris doesn't clog the motor and make sure the gasket is secure on the dust cup lid so the cyclone assembly has a tight seal. You can also purchase a new dust cup lid or dust cup in case yours has cracked through all the cleanings you'll be doing. Feel free to contact us at (866) 972-8227 with any questions.
