The best robot vacuum deals of May 2023

It depends, but usually you don’t need to empty the trash can after each use. Many robot vacuums can self-empty at their docking station, so you don’t have to clean the actual robot.

Self-emptying robot vacuums can collect anywhere from 30 to 60 days’ worth of dust and allergens, making cleaning easier.

Other robot vacuums don’t offer self-emptying features, but they’re also more affordable. Depending on how much dust and pet hair you have on your floor, you may be able to get a few uses before emptying the trash can.

It’s worth reading the product description, as it will tell you how long the bin will last between sessions, as well as whether or not it offers a self-cleaning option.
