Quick answer
The US T29151N2 filter is labelled nonwashable. Check the exact replacement SKU before using water. The safest next step is to match the full robot code and OEM SKU on the linked manufacturer source before ordering.
Step-by-step check
- Read the full robot name and model code on its underside label.
- Copy the installed filter SKU from the package or order record.
- Match both identifiers on the current manufacturer page for your country.
- Read exclusions and the selected product variant, not just its title.
- Follow cleaning instructions for that exact replacement. If instructions are missing or contradictory, pause wet cleaning and ask eufy.
Fit and washability are separate checks
The current eufy US T29151N2 listing identifies the replacement as nonwashable and lists the RoboVac 11S Max among compatible models. Do not rinse this replacement simply because another manual or shop calls an 11S Max filter washable. Compatibility with a robot does not establish the cleaning method for every filter sold for it.
Keep 11S and 11S Max separate
The official filter-ordering guide tells owners to check the model on the bottom of the robot. It separates the non-Max 11S family from the 11S Max family. The US T29151N2 listing excludes the non-Max 11S. A seller title that drops “Max” is not precise enough. Our nameplate guide explains what to record.
Why the manual can seem to disagree
Manual 51005003762 V01 covers multiple models. The maintenance spread separates 11S T2108 from 11S Max T2126 and 15C Max T2128. Its Max diagram shows rinsing and drying; the non-Max high-performance-filter warning is in another column. Flattened text can lose that distinction. We checked the official manual landing page and visually inspected a same-version manual copy, printed pages 18–19. This is not evidence that every later replacement is washable. Follow the instructions for the exact installed filter; the US replacement page labels T29151N2 nonwashable.
UK T29150N1 remains a separate, unresolved question
The UK T29150N1 product URL returned 404 during our 17 October review. An indexed washable-filter title did not establish a current direct source or replacement destination. This is not proof of discontinuation, and the US N2 instructions do not establish how the UK N1 part should be cleaned. If your package says T29150N1, ask eufy for current instructions for that identifier. Read our regional SKU guide before substituting a different code.
Copy this confirmation message
“My robot is [full name and model code], bought in [country]. The filter package or order says [SKU]. Is this exact filter washable? Please send its cleaning and drying instructions and confirm compatibility with my robot.” Include a clear identifier photo if eufy requests it; a filter’s appearance alone does not prove its material or washing method.
The G30 note is about purchase date
The same US listing directs owners of G30 robots bought after 14 August 2023 to a G40 filter. This is a purchase-date condition, not a manufacturing-date condition, and not a new 11S Max rule. G30 owners should check the purchase record and current exact-product guidance instead of extending the rule to other models.
Before you fit a replacement
Third-party filters need their own compatibility and cleaning evidence. Do not treat a seller’s compatible-model list as OEM confirmation. If a filter needs force or prevents the dust collector from closing, stop and recheck the identifiers rather than modifying it. Use the filter compatibility checklist and the exact-model finder for your next check.
Before you order
- Recheck every suffix on the robot and dock.
- Open the dated source instead of relying on a search-result or marketplace title.
- If the local SKU differs, keep the relationship Not confirmed and submit the official regional page.
