Buying Guides
People ask how many years a robot lasts as if there were a single number. There is not. The plastic shell can sit on a shelf for a decade. The battery, the app, and the spare filter decide whether it is still a robot or a paperweight.
This is not a ranking of brands and not a promise of service life. It is a way to think about vacuum discs, desk companions, and anything else with a motor and an account. For the day the vendor vanishes entirely, read what still works when the company shuts down.
ⓘ Quick Answer
Treat a home robot as an appliance with a replaceable battery and published parts, not as a family member with a lifespan. Vacuums that you can service often stay useful for years. Companions die faster when the personality lives in the cloud. Sealed batteries and dead apps are how working motors become junk.
Three clocks, not one
Hardware clock
Wheels, gears, and brushes wear. Filters clog. This clock is honest: you can see it and you can often buy a part.
Battery clock
Runtime shrinks. If the pack is user-replaceable, the robot can get a second life. If it is glued in, the body inherits the pack’s expiry.
Software clock
Apps lose store listings, logins, and “AI” features. A vacuum that still starts from a physical button outlives a companion that only talks through a server.
Those clocks do not expire together. Owners get angry when the one they ignored dies first.
Vacuums versus companions
A Roomba or Deebot is a cleaning appliance. If you can buy a battery, a brush, and a filter in your country, you can keep it earning its keep. Mapping and app scheduling are conveniences; many models still run a physical clean if the phone app is sulking. That is a longer useful life than the marketing cycle.
Desk companions such as Eilik or EMO are closer to connected toys. Motors are simple. Charm is software. When the account, the voice, or the store app goes, you still have a fidget — or you have a silent figurine. Pocket chat pets are even more exposed because conversation is the product.
💡 What to Check
Search the exact battery and filter part numbers plus your country. If nothing comes up, assume you are buying one generation of parts. Ask what works with no account. That answer is the real lifespan.
What you can actually plan for
Do not trust round numbers on blogs. Plan instead: one extra battery if the design allows it, a year of consumables in the drawer, and a vendor that still sells parts. Budget a replacement when the app is already neglected in reviews. Price-tier thinking in what you get at each price matters here, because a sealed cheap robot can be more disposable than a dearer one with screws you can open.
How robots actually leave service
- Battery swollen or too weak to finish a room, and no spare sold.
- Main brush bearings gone, and the part is unique to a dead model line.
- App removed from the store, so you cannot add a new phone.
- Cloud personality or maps locked behind a login that no longer works.
- Owner gave up on emptying, charging, or hair cuts — social death, not mechanical death.
The last one is common and is not a manufacturing defect. A robot you will not maintain has a lifespan of weeks, whatever the battery chemistry.
Buying for a longer life
Prefer published spare parts, a replaceable battery, and local returns. Prefer features that still do something offline. Avoid marketplace specials with no service path. If the job is cleaning, a boring vacuum with parts will outlast a charming companion you cannot open. If the job is delight, accept that delight is rented from a server until it is not.
Longevity checklist
Before you count on years
- Is the battery user-replaceable, with a part number I can find for sale?
- Are brushes, filters, and bags sold in my country today?
- What still runs with no internet and no account?
- Is the manufacturer still updating the app, or only still running ads?
- If the company vanished next year, would this still do the physical job?
Final Thoughts
Ask how it dies, not how long the plastic lasts. Compare vacuums and companions on Robot.help with parts and offline behaviour in mind. A robot you can service is an appliance. A robot you can only log into is a subscription with motors.
Frequently Asked Questions
How many years should a robot vacuum last?
There is no honest single figure. With replaceable parts, many households use one for years. With a sealed battery, life is roughly the life of that pack and your patience.
Do companion robots last as long as vacuums?
Usually not as tools, because the value is software. The motors may still twitch after the personality is gone.
Is an extended warranty worth it?
Only if it covers the battery and you can actually claim in your country. Read the exclusions. Consumables are almost never included.
Can I keep using it if the app dies?
Some vacuums still start from the robot. Many companions and mapping features cannot. That split is the purchase.
Should I buy last year’s model?
Often yes, if parts are still in channel. A new model with no spares yet is not automatically the longer-lived one.
