5 Things to Know About Robot Vacuum Runtime

Runtime matters more than battery size A hundred minutes of runtime can clean 1,200 square feet before a baby wakes from a nap. That is the real metric that matters.

Finishing the job is what counts A robot vacuum is only useful if it finishes before you notice it started. Raw battery numbers mean little if the vacuum cannot complete your floor plan.

Docking matters The robot must return to its dock after cleaning. If it dies mid-floor, you lose the convenience.

Floor plan size determines runtime needs Measure the area you need cleaned. A 1,200-square-foot downstairs requires at least 100 minutes of runtime.

Real-world use beats spec sheets Ignore marketing claims. Test whether the vacuum can finish your home in one charge during a typical nap or errand.
