QUESTION
Should I buy a cordless vacuum if I already have a robot vacuum?
Yes—if you want a complete cleaning setup, a cordless vacuum is still worth having alongside a robot vacuum. A robot is best for routine floor maintenance; a cordless vacuum handles the things robots miss: stairs, corners, baseboards, upholstery, car interiors, shelves, spills, and higher/vertical surfaces.
Skip the cordless vacuum only if your home is very small, mostly open hard flooring, has no stairs/pets/kids, and you’re happy doing occasional detail cleaning with another tool.
Best practical setup: let the robot run frequently for dust and crumbs on open floors, then use a cordless stick/handheld for quick spot-cleaning and above-floor jobs.
