This guide covers robot-mounted consumables for the U.S. eufy RoboVac 11S MAX (model T2126). It does not cover the standard RoboVac 11S (T2108) or self-empty dock bags; the 11S MAX uses a charging base, not an auto-empty station.
Check the variant: Check the robot label for T2126 / 11S MAX. The standard 11S (T2108) has a different filter assembly; this guide's 3-in-1 filter is eufy part T29151N2. Match the part number and selected model on the listing before checkout.

2 sets of genuine eufy unibody filters (part T29151N2), according to the Amazon product details.

Replace when: eufy recommends replacing the filter every 2 months, depending on use. Replace sooner if it is damaged or remains clogged after cleaning.
Before buying: This is the 11S MAX 3-in-1 filter, not the standard 11S (T2108) high-performance, foam and pre-filter assembly. eufy describes T29151N2 as non-washable; clean it dry and follow the listing’s instructions.
Fit: The Amazon listing’s model details and eufy product page identify the T2907031 brush for the 11S MAX; eufy’s compatibility panel also names the 11S Max.
Replace when: The manual recommends replacing the rolling brush every 6–12 months, depending on use. Remove wrapped hair and debris first; replace it if the roller or end fittings are worn or damaged.
Before buying: This listing is for one brush only. The brush guard is a separate component; inspect it and match its fit separately if it also needs replacement.
THE MODEL IN THIS GUIDE
Original eufy RoboVac 11S MAX robot vacuum
Amazon identifies this black 11S MAX listing as model AK-T2126. Confirm the selected 11S MAX model and included charging base on the live listing; the 15C MAX and standard 11S are separate models.
The 11S MAX (T2126) uses one 3-in-1 unibody filter. The standard 11S (T2108) manual section shows a separate high-performance filter, foam filter and pre-filter. Do not choose a filter by the shared “11S” name alone.
Rolling brush
eufy’s T2907031 rolling brush listing includes the 11S MAX. The Amazon card is the single-brush offer; its brush guard is not included.
Side brush and brush guard
The manual lists both as replaceable robot parts. eufy’s T29161N2 Max-series kit is listed for the 11S MAX and includes four side brushes and one brush guard. A standalone Amazon side-brush page had no featured offer when checked, so it is not presented as a buy card.
Dock bags
The 11S MAX has a charging base, not a self-emptying dock, so there is no dock dust bag to replace.

Before you order
Which replacement filter fits the RoboVac 11S MAX?
For model T2126, choose eufy’s T29151N2 unibody 3-in-1 filter. The standard 11S (T2108) uses a different three-piece filter assembly, so a generic listing that only says “11S” is not enough to confirm fit.
Can I wash the 11S MAX replacement filter?
eufy describes T29151N2 as non-washable. Clean dust from it with a vacuum or cleaning brush, and follow the current manufacturer instructions if the filter becomes wet.
Does the eufy 11S MAX use dock dust bags?
No. Its charging base does not empty the robot’s dust collector into a disposable bag. The model’s consumables include the robot filter and brushes instead.
Where can I find 11S MAX side brushes and a brush guard?
eufy lists a Max-series maintenance kit, T29161N2, for the 11S MAX. The manufacturer describes that kit as including four side brushes and a brush guard. Check the current eufy kit contents and exact model before buying.
