Robot Vacuum Warranty: How Long Is It Really, By Brand? (2026)

Quick Answer: Every major robot vacuum brand’s standard warranty is one year, not the two years that gets repeated across comparison sites. iRobot’s own limited-warranty page covers Roomba for 1 year of parts and labor (battery only 6 months), Roborock’s official terms state 1 year standard with 2-year coverage sold as a paid extended-warranty add-on, and Shark’s own Best Buy listing for its PowerDetect robot specifies a 1-year limited warranty — despite SharkNinja’s corded vacuums carrying a famous 5-year warranty. Dreame and Ecovacs ship with 1 year too, and eufy covers 12 months with no registration required. If you want more than a year, you’re buying an extended plan, not activating a hidden manufacturer benefit.

A robot vacuum warranty sounds like a simple number until you actually go looking for it on the brand’s own site — and the number that shows up is almost always smaller than what gets quoted in “brand comparison” articles floating around the web. We checked each major brand’s own official warranty page rather than trusting the aggregator numbers, and the pattern is consistent: one year is the real standard, and anything longer is either a paid upsell or doesn’t apply to robot vacuums the way it applies to the rest of that brand’s lineup.

What each brand’s warranty page actually says

Two of these are worth spelling out because they contradict what a lot of “warranty comparison” content repeats. First: Shark’s parent company SharkNinja is genuinely known for a 5-year limited warranty — but that’s on its corded and upright vacuums. The Best Buy listing for its own PowerDetect Self-Empty Robot states a 1-year limited warranty instead, meaning the brand’s flagship warranty claim doesn’t carry over to the robot line at all. Second: Dreame’s product-registration page explicitly excludes robot vacuums from the free registration-based extension that applies to its other products — on a Dreame robot, the only route to 2 years of coverage is buying a separate extended-warranty plan, not registering the product for free within 30 days like older guidance suggested.

What’s actually covered — and what isn’t

Across every brand we checked, coverage and exclusions follow the same basic pattern:

• Covered: the main motor, navigation hardware (LiDAR or camera modules), circuit boards, wheels, and structural defects in materials or workmanship.
• Not covered: brush rolls, side brushes, filters, mop pads, and dust bags — these are consumables by design, meant to be replaced on a schedule (see our robot vacuum filter replacement guide for typical intervals).
• Battery — a special case: a battery that fails outright (won’t hold any charge) is generally covered, but normal capacity loss from daily charge cycles is not treated as a defect on any brand’s terms. iRobot goes further than most by writing a separate, shorter 6-month window specifically for the battery, even though the robot itself gets a full year. See our robot vacuum battery replacement guide for what a replacement actually costs once you’re past that window.
• What voids it everywhere: buying from an unauthorized reseller, opening the robot’s main housing yourself, water damage beyond normal mopping use, and commercial or outdoor use.

Buying direct through Amazon also keeps your order history and receipt in one place if you ever need to prove purchase date for a claim — try Amazon Prime free for 30 days and most models ship in two days.

How to actually file a warranty claim

1. Find your proof of purchase. An order confirmation email or receipt with the purchase date is required by every brand above — without it, even a clear manufacturing defect can be denied.
2. Check the brand’s own support site, not a retailer’s return desk. Past a retailer’s own return window (often 30–90 days), a warranty claim goes through the manufacturer directly — iRobot, Roborock, eufy, Shark, Dreame, and Ecovacs all run their own dedicated warranty-claim portals.
3. Describe the specific failure, not just “it stopped working.” A claim for a defect in the motor, navigation sensor, or mainboard moves faster than a vague description — brands often ask for a short video of the actual fault (an error code, a grinding noise, a robot that won’t dock).
4. Confirm it was bought new from an authorized source. This is the single most common reason a legitimate-looking claim gets denied — a robot bought secondhand, from an unauthorized marketplace reseller, or already refurbished by someone other than the brand generally isn’t covered under the standard new-unit warranty at all.

The bottom line

The “2-year warranty” you’ll see quoted for iRobot, Roborock, and Shark in a lot of comparison content isn’t what any of the three actually offers as standard — each brand’s own official terms specify 1 year, with 2 years available only as a separate paid extended-warranty purchase (or, on Shark’s robots specifically, not offered at all). Dreame and Ecovacs match that 1-year baseline, and eufy’s 12-month, no-registration-required policy is about as straightforward as any of them get. None of this means these robots are unreliable — most failures inside that first year are covered cleanly — but it’s worth going in expecting one year of real coverage, not two, and deciding whether a paid extended plan is worth it based on the robot’s price rather than an advertised number that turns out to be optional.
