Editorial note (rewritten July 30, 2026): this guide consolidates the care schedules and replacement intervals that Roborock, iRobot, Dreame, Ecovacs, and Eufy publish in their product documentation, plus typical accessory pricing. Intervals are manufacturer recommendations — shedding pets shorten all of them. See the editorial standards.
A robot vacuum is a machine with consumables, filters, and a dozen optical sensors that all degrade quietly. The manufacturers' own care documentation is surprisingly consistent about what actually needs doing — and it amounts to roughly 15 minutes a month. Here is the consolidated schedule.
Daily (only without a self-empty dock)
- Empty the onboard bin. Manufacturers recommend emptying after each run; a packed bin chokes airflow, which is why self-empty docks are the single best longevity feature. Owners of dock-equipped models can skip daily care entirely.
- Glance for wrapped hair on the roller and wheels before the next run.
Weekly (about 5 minutes) — the one that matters
- Wipe every sensor with a dry microfiber cloth: the LiDAR window or turret, cliff sensors underneath, wall/edge sensors, camera lenses, and the dock's alignment sensors. Optical sensors reading through dust are behind most "robot suddenly navigates badly," "won't dock," and phantom-obstacle complaints — which is why every brand's troubleshooting guide starts with cleaning them.
- Clear the main roller and side brush. Rubber rollers shed hair better by design but still collect wraps at the axle ends; most current rollers pop out without tools.
- Tap out the filter against a bin. Don't wash HEPA-type filters unless the manual explicitly allows it — most are damaged by water.
- Check wheels for wound hair; tweezers work at the axles.
Monthly (about 10 minutes)
- Service the dock: wipe charging contacts, clear the auto-empty inlet port, and on mop-washing docks clean the wash tray and empty/rinse the dirty-water tank — the tray is where mop docks grow grime.
- Check the map in the app; re-run a mapping pass if rooms have drifted or furniture moved substantially.
- Install firmware updates. Vendors ship navigation and obstacle-avoidance improvements this way, not just fixes; leave auto-update on where offered.
Every 3-6 months: the consumables
| Part | Manufacturer-recommended interval | Typical price |
|---|---|---|
| Filter | 2-3 months with pets, up to 6 without | $10-$20 |
| Main roller | 6-12 months (rubber); 3-6 (bristle) | $18-$30 |
| Side brush | 3-6 months | $5-$10 |
| Mop pads / roller sleeve | 2-3 months of regular mopping | $10-$20 |
| Dock dust bags | per fill — commonly rated 4-8 weeks each | $1-$3 per bag |
| Battery | when runtime degrades badly — typically year 3+ | $40-$80 |
Budget roughly $30-$85 a year in consumables depending on brand and pets. Multi-pack third-party kits cut that substantially; check connector and size compatibility for your exact model, since brands revise parts between generations. One exception to the bag line: Ecovacs' Deebot X12 OmniCyclone uses a bagless cyclone dock — no recurring bag cost at all, at the price of hands-on canister emptying.
Repair or replace?
| Failure | Typical cost | Sensible call |
|---|---|---|
| "Sensor" errors, bad navigation | $0 | Clean the sensors first — the most common fix in every brand's support flow |
| Worn battery | $40-$80 | Replace the battery on any robot under ~4 years old |
| Brush motor | $80-$150 | Worth it on a recent flagship; marginal on a budget model |
| Main suction motor / mainboard | $150-$250 | Usually replace the robot — mid-range prices have fallen below repair cost |
The replace math changed with 2026 price compression: when a former flagship sells for ~$599, a $250 mainboard repair on an aging mid-ranger is hard to justify.
Habits that extend lifespan
- Run it frequently rather than rarely. Short, frequent runs over light debris load the motor and filter less than occasional runs through a week of buildup — the same reason manufacturers rate filters in months of daily use.
- Keep the dock on a hard, level surface with the clearance the manual specifies; misaligned docking is a leading cause of failed auto-empty cycles.
- Mind water: use plain water or the brand's own solution in mop tanks — most manuals void support for household floor cleaners, which foam and gum the pumps.
- Store it charged. Lithium packs kept at full drain or dead-flat for long idle periods (vacation homes, seasonal use) age fastest; brands recommend a partial charge and power-off for storage.
TL;DR schedule: daily — nothing (with a dock). Weekly — 5 minutes: sensors, roller, filter tap. Monthly — 10 minutes: dock service, map check, firmware. Quarterly-ish — rotate consumables. That routine is the difference between a robot that fades in year two and one that quietly runs for five-plus.
