What cordless vacuum features matter most with a robot vacuum?

The most useful cordless vacuum features to pair with a robot vacuum are: strong handheld/above-floor cleaning, good edge and corner pickup, lightweight handling, quick swap-and-go convenience, and a battery that lasts long enough for spot jobs.

If you already have a robot doing the daily floor work, prioritize a cordless vacuum that is easy to grab for stairs, upholstery, car cleaning, baseboards, and quick spills—not one that tries to be the strongest all-around vacuum.

What to look for first:

• Lightweight body and easy maneuvering
• Converting to a handheld mode
• Useful attachments: crevice tool, upholstery tool, dusting brush, and a motorized mini brush for pet hair
• Decent battery life for short cleanups, plus removable battery if possible
• Bin and filter design that is easy to empty and wash
• Good pickup on edges, corners, and fabric, not just open floors

If you have pets, a mini motorized brush matters a lot. If you have stairs, weight matters more than raw power. If you have mostly hard floors and a robot already handles crumbs, you can usually skip extra floor-focused features and focus on attachments and convenience.
