A well-chosen robot vacuum should last 4-7 years of daily use. What determines where you land on that range: brand, maintenance habits, and whether you use it in a pet or non-pet home.
Here's what actually fails, and how to extend the life of yours.
The average lifespan
Premium models (Roborock, Roomba, Dreame flagships): 5-7 years of daily use. Mid-tier: 3-5 years. Budget: 2-4 years. Battery-only replacement can extend any of these by 1-2 years.
The most important factor is brand: iRobot and Roborock both have long-running units still in daily service. No-name brands often become e-waste within 24 months.
What fails first
Battery: typically the first failure point, around year 3-4. Replaceable on almost every current model for $30-$80.
Brushes and side brushes: consumable — replace every 6-12 months. Filters: every 2-3 months.
Motor and gearbox: rarely fails within a warrantied lifespan on premium brands. Wheels and drop sensors are the second most common failure after battery, and are also easily replaced.
The maintenance schedule that maximises life
Weekly: check the main brush for tangled hair, empty bin (if not self-emptying), rinse mop pads.
Monthly: wash the filter, clean the sensors with a dry microfiber cloth, wipe the charging contacts.
Every 3 months: replace filter. Every 6-12 months: replace main brush and side brushes. Year 3+: replace battery when runtime drops noticeably.

Final verdict
A premium robot vacuum, maintained well, lasts 5-7 years — cheaper per year than most stick vacuums. Buy from a brand with a strong parts network, follow the maintenance schedule, and expect to replace the battery once in the robot's lifetime.
