S4 Max readiness reassessed as discontinued status narrows new-owner path
Discontinuation confirmed by Q2 2024, combined with third-party stock thinning and a narrowed accessory supply horizon, prompted a reassessment of the S4 Max's new-buyer readiness.
Full assessment
AutonomyL3 heldReadinessWait → Promising progressScoreValue -5The Level III classification is unchanged; the readiness shift reflects the purchase-path risk for new owners, not a performance regression. Accessory availability over the next 12-24 months is the key variable to monitor.
Impact on autonomy
- Level III classification retained; LiDAR navigation and mapping unaffected
- No firmware deprecation announced; app support continues under current Roborock app
- Conditional Autonomy capability documented through multi-year owner reports remains valid
Impact on readiness
- New-buyer path now limited to third-party and used-market channels
- Accessory supply (brushes, filters) narrows predictably for discontinued models
- Existing owners on established maintenance cycles face no immediate change

S4 Max remains a strong current-generation value optionLaunched October 2020; current-generation LiDAR vacuums at comparable price now include auto-empty docks and improved obstacle avoidance not available on this platformFull software support guaranteedRoborock app support continues but no commitment to feature parity with current-generation models; new routing and AI-object features are documented as current-hardware-onlyAccessories readily available long-termMain consumables stocked as of mid-2024; historical pattern for Roborock discontinued models shows accessory availability narrows within 36 months of end-of-saleDiscontinuation does not affect ownership experienceExisting owners: accurate. Prospective new owners: third-party-only purchase path introduces pricing variability and warranty uncertainty compared to official channel purchaseBottom lineThe S4 Max's classification is unchanged; the readiness shift is a purchase-path assessment, not a capability downgrade.
Technical notes3 sections
- Reassessment Basis
-
The S4 Max was classified at Level III (Conditional Autonomy) at launch and that classification remains current. The readiness reassessment is driven by commercial lifecycle position, not a hardware or software regression. The model is confirmed discontinued from Roborock’s first-party lineup, with new-purchase availability limited to third-party retailers holding remaining stock.
- Classification Unchanged
-
LiDAR-based mapping, multi-floor storage, and full-session autonomous operation remain documented and operational. The Roborock app continues to serve the S4 Max with core scheduling and zone-cleaning functionality. No firmware deprecation notice has been issued. The gap between the S4 Max’s 2,000 Pa suction and current-generation platforms (which document 10,000 Pa and above) was already present at prior assessments and does not constitute new information.
- New-Owner Risk Factors
-
Buyers sourcing the S4 Max through third-party channels after official discontinuation face: variable pricing without MSRP anchor, limited or no manufacturer warranty coverage on used units, and a supply horizon for consumable parts that narrows over a 24-36 month post-discontinuation window. These factors are characteristic of any discontinued product, not unique defects of this model.

Roborock S4 Max removed from active lineup as S4-series discontinued
Roborock ceased active sales of the S4 Max as the S4-series gave way to newer platform generations.
Full assessment
AutonomyL3 heldReadinessPromising progress heldScoreValue position unchangedThe immediate consequence is that new buyers cannot purchase through official channels, shifting the model to used-market or third-party stock. Owners should verify part availability and app support cadence before committing to long-term use.
Impact on autonomy
- Level III classification unchanged; navigation capability unaffected by discontinuation
- No firmware architecture changes accompany end-of-sale announcement
- LiDAR mapping and multi-floor support remain operational on existing units
Impact on readiness
- New purchase path eliminated from official Roborock storefront
- Third-party and used-market pricing now determines entry cost
- Replacement consumables (brushes, filters) remain available through Roborock accessories store

Technical notes3 sections
- Commercial Status
-
The S4 Max launched in October 2020 at $429 MSRP. Roborock’s active lineup shifted toward S7, S8, and Saros-series platforms through 2022 and 2023, with the S4-series receiving no successor at the same price tier. End-of-sale reflects standard product lifecycle for a four-year-old platform, not a safety or performance defect.
- Hardware Continuity
-
Existing units retain full hardware capability. LiDAR sensor, 2,000 Pa suction, and 110-minute runtime are unchanged. No hardware recall or safety notice accompanies discontinuation. The robot continues operating on the Roborock app with existing account linkages intact.
- Accessory Supply
-
Main brush assemblies, HEPA filters, and side brushes remain listed through Roborock’s accessories catalog and major third-party suppliers. No documented supply shortage at time of discontinuation. Owners on multi-year maintenance cycles should note that accessory availability for discontinued models typically narrows 24-36 months post-discontinuation.

Roborock ends Mi Home app support requiring S4 Max migration to Roborock app
Roborock discontinued Mi Home app support for its vacuum models including the S4 Max, consolidating control into the Roborock app.
Full assessment
AutonomyL3 unchangedReadinessPromising progress heldScoreScores unchangedSaved floor maps transferred for most users during migration; Xiaomi-based automation and scene integrations did not carry over. Owners using Mi Home for multi-device scenes need to rebuild those automations in the Roborock app or via separate smart-home integrations.
Impact on autonomy
- Level III navigation and mapping capabilities unaffected by app platform change
- Scheduled cleaning and room-level zone assignments preserved post-migration
- Voice assistant connections (Alexa, Google Home) require re-linking in new app
Impact on readiness
- Mi Home ecosystem integrations (Xiaomi scenes, routines) no longer available
- Roborock app provides equivalent scheduling; cross-brand Xiaomi automations require rebuilding
- Owners without Xiaomi ecosystem dependency experience no functional loss

Technical notes3 sections
- App Platform Change
-
Roborock vacuums including the S4 Max originally supported control through both the Roborock app and Xiaomi’s Mi Home app. Roborock notified users through in-app messages and support documentation that Mi Home integration would be discontinued, requiring migration to the standalone Roborock app for continued full-feature operation.
- Data Migration
-
The migration process transferred stored floor maps and room labels for the majority of users. Owner reports on r/Roborock describe cases where multi-floor configurations required partial re-mapping after account transfer. Scheduled routines migrated intact in most documented cases. Xiaomi scene triggers and cross-device automations built in Mi Home did not transfer and required manual recreation.
- Third-Party Integration Impact
-
Home Assistant users relying on community-maintained Roborock integration components needed to update their integration configuration following the API endpoint changes. The Valetudo alternative firmware remained unaffected by the app platform change. Alexa and Google Home skills required re-authorization through the Roborock app after migration.
