consumables, plus new vs refurbished coverage clocks)\
before purchase
“1-year warranty” sounds straightforward, but official warranty pages in 2026
often split coverage by product condition (new vs refurbished) and **part
type** (main unit vs battery vs consumables).
If you compare only the headline warranty number, you can misread your real
post-purchase risk.

What official sources are actually saying
1) Roborock US: 1 year for new products, 6 months for certified refurbished, with consumables carved out
On Roborock’s US Service and Warranty page, Roborock states that new products
are covered for one (1) year from purchase date, and certified refurbished
products are covered for six (6) months from purchase date.
The same page also states the limited warranty does not cover “**Consumable
components of the Product, such as brushes**,” except when damage/defect is due
to failure in non-consumable parts.
Practical takeaway: even inside one brand policy, your coverage clock can change
based on whether the product is new or certified refurbished, and consumables
may follow different treatment than core hardware.
2) ECOVACS US: 12 months for new products, 3 months for certified refurbished, and explicit consumable-part caveat
On ECOVACS’ US warranty page, ECOVACS states:
- new products: 12 months from purchase date,
- certified refurbished products: 3 months from purchase date.
The same policy says the warranty does not apply to consumable parts “**such as
batteries or side brushes that are designed to diminish over time**,” unless
failure occurred due to a defect in materials or workmanship.
Practical takeaway: battery- and brush-related failures can sit in a different
risk category than core defects, depending on failure cause and policy
interpretation.
3) Dreame US after-sales policy table: “Robot Vacuum Series” shows separate clocks by component type
On Dreame’s US after-sales policy page, the published table for “Robot Vacuum
Series” lists:
- Main body + charging/dock components: 3 years,
- Battery pack: 1 year,
- Consumable parts (for example dust-bin filter, mop, side brush, main brush):
1 month.
Practical takeaway: one product family can have multiple warranty clocks at the
same time, so “warranty length” is not one single number.
Why headline warranty claims are not directly interchangeable
Layer A: New vs refurbished status changes the baseline clock
Roborock and ECOVACS both publish shorter certified-refurbished windows than
their new-product windows.
Layer B: Component class changes coverage duration
Dreame’s policy table explicitly separates main body, battery pack, and
consumables into different durations.
Layer C: “Consumable” language can include batteries or brushes depending on policy wording
ECOVACS explicitly lists batteries/side brushes as consumables designed to
diminish over time. Roborock explicitly lists consumable components such as
brushes.
Layer D: Defect-causation exceptions matter
Both Roborock and ECOVACS include wording that can preserve coverage if
consumable-part failure is tied to defects in materials/workmanship (or
non-consumable-part defects).
Internal pages to cross-check before buying
Use these ui44 pages to compare robot context before checkout:
- Robots: Roborock Saros Z70,
- Manufacturers: Roborock,
7-step buyer workflow for warranty-risk checks
- Capture the exact policy page URL for your purchase channel before paying.
- Separate coverage clocks for new vs certified-refurbished products.
- List component classes separately: main unit, battery, and consumables.
- Check whether the policy treats your expected failure as wear/aging vs
defect.
- Save proof-of-purchase and serial number evidence in one folder before first
use.
- If buying refurbished/open-box, confirm the exact refurbished warranty window
in writing.
- Re-check policy pages right before checkout, because warranty wording can
change.
Frequently Asked Questions
If a listing says “1-year warranty,” can some parts still have shorter coverage?
Yes. Official policies can apply separate durations to specific part classes
(for example consumables) even when a headline warranty window is present.
Are batteries always treated as normal warranty parts?
Not always. ECOVACS’ published policy explicitly lists batteries among
consumable parts designed to diminish over time, with a defect-based exception.
Can refurbished coverage be shorter even from the official brand store?
Yes. Both Roborock and ECOVACS publish shorter certified-refurbished windows
than their new-product windows on the cited pages.
Bottom line for buyers
For robot vacuums, warranty risk is usually a multi-clock system, not one
number.
Before purchase, verify coverage by product condition and component type, and do
not treat “1-year warranty” as a complete description of your real protection.

This is a time-sensitive buyer topic. Re-check all linked policy pages right
before purchase and retain screenshots/PDF copies, because warranty language can
update after launch, promotions, or regional policy refreshes.
