Because of dust, dander, and pollen, the best robot vacuums for pet owners have good filtration systems. A top-quality filter captures all those particulates and makes sure it gets into the vacuum’s dust bin. Some robots use HEPA filters, which catch even smaller particles. Battery life and charging time are also important, as is run time. Consider those factors when comparing and contrasting the pet-specific vacuums that make your final cut. The amount of noise made by the vacuum is also important for pet owners, since many cats and dogs aren’t fond of loud robot vacuum cleaners streaking through the house bumping into things. While some are as loud as traditional vacuums, others are much quieter and make a better choice.
