Robot Battery Replacement Cost: Vacuums, Mowers, and Pool Cleaners

A replacement battery for a robot vacuum costs about $60 to $170, and one for a recent Husqvarna Automower about $220 to $280, based on the sellers’ listings below. Corded robotic pool cleaners have no battery at all. Cordless pool robots are another matter: Aiper says its Scuba V3 battery is sealed and not sold separately, and one seller lists a Dolphin Liberty battery at $1,270.85.

Last reviewed: October 2026. Every price below comes from the seller’s own page, and stock status is as we found it. Non-OEM batteries are labeled.

Robot vacuums

iRobot’s US store lists these Roomba batteries. All four were out of stock when we checked.

McKinley Battery for e, i, and j series: $99.99
Battery for Roomba s series: $119.99
Roomba 3300 battery, for the 900 series and select 600 and 800 series: $129.99
Battery for Roomba Combo j9+ and j7+: $169.99

Non-OEM batteries cost less. Batterymart lists a replacement for many recent Roborock models, including the Qrevo and Saros lines, at $62.95. It is not made by Roborock; Batterymart says it meets or exceeds the original specifications.

iRobot’s warranty includes the battery for one year but excludes normal battery wear, so a battery that has simply aged is usually the owner’s cost. More in Roomba repair and warranty.

Robotic mowers

Husqvarna Automower, recent 430X, 450X, and 550 family: $219.99 at Robotic Mower Services, an authorized Automower dealer in Pennsylvania.
Same family, OEM part 593247401: $279.99 at HL Supply in Florida, out of stock when we checked.
Older 430X with the original blue battery: a $274.99 update kit with battery, cradle, and harness at Robotic Mower Services, marked down from $299.99.
Automower 265ACX, 2012 to 2015: $126.95 for a non-OEM replacement at Batterymart.

Check the model and serial number before ordering, because compatibility depends on both.

Some mowers share batteries with the maker’s power tools. Worx’s help pages say its Powershare batteries are compatible with the Landroid, so a Landroid owner may already own a spare.

Husqvarna’s annual dealer service includes battery testing. See Automower service and robotic mower maintenance.

Robotic pool cleaners

Corded cleaners have no battery. They run from a power supply beside the pool, so the parts to price are the power supply, the cable, and the motor unit. See the pool cleaner repair guide.
Aiper cordless cleaners: Aiper says the Scuba V3 battery is sealed, is not designed for owner replacement, and is not sold as a separate part. A failing battery is handled as a claim under the V3’s 2-year warranty. Aiper offers paid out-of-warranty service but does not publish its prices.
Dolphin Liberty cordless: Poolweb lists a Maytronics replacement battery for the Liberty at $1,270.85, with an extended manufacturer lead time.

With a cordless pool robot, check the warranty length before you buy.

Frequently asked questions

Should I buy a genuine or a non-OEM battery?

Non-OEM batteries cost less, but quality varies, and a fault caused by a non-approved part may not be covered by the manufacturer. One iRobot limited warranty we read excludes damage from spare parts that iRobot did not provide or recommend.

Is battery wear covered by warranty?

Normal wear usually is not. iRobot’s warranty excludes normal battery wear, while its paid Protect plans replace a battery that no longer holds a charge. Aiper’s support page uses 40 to 50 minutes of run time as the threshold for a defective V3 battery under warranty.

Can I replace the battery myself?

Roomba and Automower batteries are sold as replacement parts, as the listings above show. Cordless pool robots can be different: Aiper says its Scuba V3 battery is not designed for owner replacement.
