Some cordless vacuum cleaners (like some of the best vacuums for pet hair above) do come with docking stations. These provide one of the easiest ways to recharge a cordless unit as it is as simple as docking it into place, making sure that the pins are aligned correctly, and voila! You’re good to go. Some pet vacuums even come with wireless connectivity that utilizes a dedicated app in your smartphone to tell you if it’s done recharging. Others come with automatic shutoff features that help to cut power to the charging base, saving your unit from possible overcharging.\r
