The battery is the first point to examine: a lithium-ion loses 20 to 30 % capacity after four years of use, which directly reduces session autonomy. The traceability of the manufacturer cloud account is equally critical for Mammotion, Segway Navimow and Husqvarna EPOS models, as a robot not unbound by its previous owner can be unusable from the start. For wired models, checking that the boundary wire is still laid at the seller's avoids an 8 to 15 hour installation to plan. A 35 to 55 % discount on the new price is reasonable for a 2 to 4 year old model in good condition with maintenance history.
Used or reconditioned: two markets not to confuse
These two terms often circulate as synonyms in listings, but they cover very different realities in terms of risk and price.
Used refers to a private sale, on Le Bon Coin, Facebook Marketplace, Vinted or eBay. The robot is sold as seen, without prior inspection, without legal warranty beyond the guarantee against hidden defects (difficult to enforce in practice). The price is freely negotiated and generally sits between 35 and 50 % of the current new price, representing a 50 to 65 % discount.
Reconditioned refers to a unit refurbished by a professional: cleaning, replacement of defective parts, functional tests, then resale with a contractual warranty of 6 to 24 months. The main players are Back Market, the Husqvarna Reconditioned programme distributed through authorised dealers, and a few specialist sites. The discount is lower, 25 to 40 % below the new price, but the risk is markedly reduced.
The choice between the two depends on the buyer's profile. A DIYer comfortable with disassembly and ordering parts can benefit from a good deal on the P2P used market. A private buyer who wants to install the robot and forget about it for five years should pay the premium for a guaranteed reconditioned unit.
The 10-point checklist before buying
1. Actual battery condition
This is criterion number 1, without exception. A lithium-ion battery supports 800 to 1 200 useful cycles before losing significant capacity. After four years of intensive use (May to October, two cycles per day), the loss reaches 20 to 30 %. Ask the seller for the year of purchase, the approximate number of cycles and the observed session autonomy. If possible, run a full cycle on site: the actual duration must represent at least 70 % of the value stated by the manufacturer. Below that, factor the cost of a new battery (60 to 180 € depending on the model) into the negotiation.
2. Manufacturer cloud account and IMEI/serial number
This point is critical for Mammotion (LUBA, YUKA), Segway Navimow, Husqvarna EPOS, Dreame and Eufy. These robots are linked to a single owner account: mapping, scheduling and sometimes starting pass through this account. If the previous owner does not formally unbind the robot before the sale, the app refuses to register the unit with the new buyer. Verify unbinding before paying by powering on the robot and attempting registration from your own account. Note the serial number or IMEI to confirm consistency with the original invoice.
3. Boundary wire: present or to be re-laid?
For wired models, namely Husqvarna Automower outside the NERA and EPOS ranges, Worx Landroid, Gardena Sileno, Stihl iMOW non-X and Robomow, the buried or pegged boundary wire is inseparable from the robot. Without this wire already installed at the previous owner's property, budget 80 to 150 € for new cable plus 8 to 15 hours of installation depending on garden size and complexity. Request photos of the wire in place, the layout and the charging station in its real environment. A seller unable to provide these photos warrants caution.
4. Condition of blades and chassis
Pivoting blades wear normally and their replacement costs 15 to 30 €: this is a common part, available from all dealers. Scratches on the underside of the chassis are normal after several seasons. However, a deformed bumper or visibly displaced front sensors following an impact indicate an undeclared incident. Running the robot for a short mowing session before purchase helps detect abnormal cutting noise, excessive vibration or erratic behaviour at zone edges.
5. Charging station cable and contacts
The station power cable is exposed to rodents, petrol mowers and UV. Check for bite marks, exposed conductors or makeshift repairs with insulating tape. Gold-plated charging contacts oxidise if left in prolonged humidity: cleaning with isopropyl alcohol is often sufficient, but deep oxidation requires station replacement (50 to 150 € depending on the model). Always test a full charge cycle before concluding the transaction.
6. Firmware updates
A robot left without connection for two to three years may be stuck on an old firmware version incompatible with recent app features. For Mammotion, Segway Navimow and Husqvarna EPOS, OTA updates require an active account and an unbound robot. Ask the seller for the firmware version shown in settings. If the version is more than two years old, check with the manufacturer's support that the update remains possible once the account transfer is completed.
7. Sensors (collision, lift, rain, GPS)
The lift sensor is a mandatory safety device: when the robot is lifted, the blades must stop in less than one second. Test this point without exception. The rain sensor is checked by lightly moistening the upper shell: the robot must interrupt its session and return to the station. For RTK or differential GPS models, ensure the base station is supplied with the robot: without it, wire-free navigation is impossible. Consult our complete guide to robot mower navigation systems to identify the essential components according to the technology.
8. Documented maintenance history
A robot serviced annually through an authorised network (winter storage, cleaning, sensor checks) reaches a 5 to 8 year life expectancy. An unserviced robot tops out at 3 to 4 years. Request maintenance invoices, winter-storage receipts (Husqvarna and Stihl offer this service through their networks), and blade replacement receipts. The total absence of documents is not a deal-breaker, but it justifies an additional 10 to 15 % discount compared with a model with complete history.
9. Availability of spare parts
Before finalising the purchase, check on the manufacturer's website or with an authorised dealer that the main parts are still sold: battery, blades, charging station, motherboard. For models discontinued more than five years ago, batteries become scarce and prices rise. Husqvarna and Stihl maintain parts for 8 to 10 years after the end of production. Mammotion, Segway and Dreame are newer brands: their long-term parts policy must be confirmed case by case.
10. Price consistency
Compare the asking price with the current new price (not the launch price, often obsolete) and apply the expected discount: 50 to 65 % for P2P used, 25 to 40 % for professional reconditioned. A price below 30 % of the new price on a model less than three years old should raise an alert. Common causes: non-functional battery, robot locked by an unbound cloud account, or dubious provenance. Cross-check the serial number against the original invoice. To calibrate your budget, our Top 10 comparison across all ranges gives the reference new prices by model.
Brand-specific pitfalls
Husqvarna
EPOS and NERA models use the My Automower account to store mapping and authorise starting. If the previous owner has not unbound the robot from their app before the sale, the new buyer cannot register the unit. Husqvarna offers unlocking through an authorised dealer, charged at 30 to 80 € depending on the outlet. For classic wired models (305, 310, 315), the cloud risk is absent, making P2P used purchases considerably simpler.
Mammotion (LUBA, YUKA)
The robot's IMEI is linked to a single account in the Mammotion app. The previous owner must perform the unbinding procedure from their own account before handing over the robot. Without this step, the robot powers on but the app refuses any configuration for the new buyer, rendering the unit unusable in practice. Verify this point by powering on the robot and launching the app from your phone before paying the seller.
Segway Navimow
The Segway account is linked to the robot in the same way. The transfer procedure goes through Segway support, is free but takes 5 to 10 working days. Factor this delay into the purchase schedule: do not count on immediate commissioning. Ask the seller to initiate the procedure before handing over the robot, or agree to a two-stage payment conditional on transfer confirmation.
Stihl iMOW
Classic wired iMOW models do not rely on a heavy cloud account, which greatly simplifies used purchases. The main point to check is compatibility of the programming key (Smart Connector or iMOW app depending on generation) with the purchased model. Some sellers hand over the robot without the programming accessory, complicating zone settings. Verify that the complete set is supplied before the transaction.
Worx Landroid, Gardena Sileno, Robomow
These wired models run lightweight apps without strong cloud-account locking. P2P used purchases present no major owner-account pitfall. The points to watch remain the same as for any wired model: boundary-wire condition, station-contact oxidation, and parts availability. Worx Landroid batteries are shared with other tools in the range, easing replacement.

Where to look honestly?
P2P platforms offer the largest volume of listings. Le Bon Coin remains the leading French market by number of references: filter by brand, model and department to avoid transport costs on a fragile appliance. Facebook Marketplace allows quick negotiation and direct contact with the seller, but offers no buyer protection. Vinted sees a growing presence of robot mowers, often entry-level models. eBay offers the advantage of buyer protection via PayPal in case of dispute.
On the professional reconditioned side, Husqvarna Reconditioned is distributed through the authorised dealer network with a 24-month warranty. Back Market offers a limited but expanding catalogue of garden robots. Specialist sites tondeuse-robot.com and robotetjardin.com sometimes list reconditioned or ex-display models. Stihl and Husqvarna dealers regularly clear ex-display units at 30 % off with full manufacturer warranty: a lead worth exploring directly in store.
Specialist Facebook groups (Imow Stihl France, Automower France) form a separate channel: sellers are often enthusiasts who know their equipment, prices are sometimes high but the quality of information provided is generally reliable.
FAQ
How much discount on a used robot mower?
The discount depends on age and condition. For a 1 to 2 year old robot in good condition with invoice, aim for 30 to 45 % below the current new price. For 3 to 5 years with normal wear, 50 to 65 %. Beyond 5 years, battery risk becomes major and the discount must exceed 70 %, unless the battery has been replaced recently. These ranges apply to P2P used; professional reconditioned sits 25 to 40 % below new, warranty included.
How do you know if the battery is still good?
Ask for the robot's purchase date and approximate number of cycles. Beyond 4 years, plan for a battery replacement within 12 to 18 months (60 to 180 € depending on the model). On-site test: run a full cycle and measure the actual duration before return to the station. If autonomy is below 70 % of the manufacturer's value, negotiate the price of a new battery or deduct that amount directly from the asking price.
Is the manufacturer cloud account a problem on the used market?
Yes, for Mammotion, Segway Navimow, Husqvarna EPOS, Dreame and Eufy. The robot is linked to an owner account that must formally unbind it before sale. Without this procedure, the app refuses to register the robot with the new buyer, blocking mapping and sometimes starting. Verify unbinding before paying by powering on the robot and testing registration from your own account.
Should you buy a robot mower on Le Bon Coin?
Yes for wired models without cloud (Husqvarna Automower 305/310 outside EPOS, Worx Landroid, Gardena Sileno, Stihl iMOW classic), where the risk is limited to mechanical wear. No without caution for wire-free RTK or vision models: the risk of a robot locked by an unbound cloud account is too high to ignore. Always test a full cycle before purchase and require an original invoice to confirm provenance.
What warranty to expect on a reconditioned robot?
Legally, professional reconditioned units include a minimum 12-month warranty under French law. Serious resellers go up to 18 or 24 months. Husqvarna Reconditioned applies 24 months, aligned with new units. A reconditioned robot sold without written warranty is not truly reconditioned: it is used with careful packaging. Always require a named warranty document mentioning the serial number.
Is a 5-year-old robot mower still worthwhile?
Yes, if the battery has been replaced recently and spare parts are still available from the manufacturer. Husqvarna and Stihl maintain parts for 8 to 10 years after the end of production. Mammotion, Segway and Dreame are newer brands, so fleet history remains limited and long-term parts policy is less established. Beyond 5 years, negotiate a 70 % or greater discount and factor in the cost of a new battery in the first year's budget.
