This Hoover anti-allergen Upright 300 is a lightweight vacuum cleaner that uses cyclonic technology that pushes dust away from the filter and helps the filters stay cleaner for longer. It also has a HEPA filter installed, which is ideal for allergy sufferers as the washable H13 HEPA filter traps allergens and helps purify the air in your home. Not only that, this blue pets model that I have received comes with a mini turbo brush nozzle to remove stubborn pet hairs from cushions, sofas and carpets.
