Deferred EU tariff risk plus strong 618 performance lead Citi to continue preferring Ecovacs

Overview

This report focuses on the global robot vacuum cleaner and related household service robot sector, with particular analysis of the recent catalysts for Ecovacs and Roborock. Citi believes that two developments this week are positive for Ecovacs: first, the EU has not yet imposed provisional anti-dumping duties on Chinese robot lawn mowers; second, Ecovacs delivered strong 618 sales performance.

Core views

The core view is that Ecovacs offers a better near-term risk-reward profile than Roborock. On robot lawn mowers, the risk of EU provisional tariffs has been deferred, helping ease pressure on Ecovacs' related European business; in domestic sales, Ecovacs' 618 GMV grew 23% year-over-year and showed strong performance across categories including premium robot vacuums, window-cleaning robots, and Tineco floor washers. Although Roborock disclosed that its robot vacuum category ranked first in market share on Tmall, JD, and Douyin during the 618 kick-off period, the report has not yet disclosed performance for the full 618 cycle.

Analysis framework

The report adopts an event-driven and relative comparison framework, cross-analyzing developments in the EU anti-dumping investigation, 618 sales data, product mix, valuation multiples, and target prices to assess the relative attractiveness of Ecovacs and Roborock.

Methodology notes

• Event-driven analysisPolicy and tariff catalyst analysis

  EU anti-dumping investigation into robot lawn mowers

  By tracking whether the EU imposes provisional anti-dumping duties and the timing of the final ruling, the report assesses changes in the near-term risk profile of export-oriented robot lawn mower businesses.

• Relative valuationP/E target price method

  Target price valuation based on 2026E PE

  Roborock's target price of Rmb120.80 corresponds to 17x 2026E PE; Ecovacs' target price of Rmb89.3 corresponds to 25x 2026E PE, and carries a 15% premium relative to Roborock's target PE to reflect better capital returns and stronger profitability focus.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Ecovacs Robotics (603486.SS)

  Core beneficiary, rated Buy by Citi

  Strengths

  618 all-channel GMV grew 23% year-over-year; strong performance in premium robot vacuums, window-cleaning robots, and Tineco floor washers; deferred provisional tariff risk for robot lawn mowers in Europe.

  Weaknesses

  Sensitive to European robot lawn mowers, global consumer demand, tariffs, and raw material costs.

  Comparison

  Citi explicitly states that it continues to prefer Ecovacs over Roborock and assigns Ecovacs a 15% premium to Roborock in target PE.

  Risks

  Macro slowdown, weaker consumption, unsuccessful product launches, intensifying industry price competition, rising tariffs, RMB appreciation, and higher-than-expected raw material costs.

• Beijing Roborock (688169.SS)

  Comparable name, rated Neutral by Citi

  Strengths

  The company disclosed that during the 618 kick-off period, its robot vacuum category ranked first in market share on Tmall, JD, and Douyin.

  Weaknesses

  The report did not disclose performance for the full 618 cycle; compared with Ecovacs, near-term catalysts in the report are weaker.

  Comparison

  Roborock's target price is based on 17x 2026E PE, while Ecovacs' target price is based on 25x 2026E PE and enjoys a relative premium.

  Risks

  Macro slowdown, weaker consumption, unsuccessful product launches, intensifying price competition, rising tariffs, RMB appreciation, and higher-than-expected raw material costs.

Impact & implications

From an investment perspective, the report reinforces Ecovacs' near-term positive catalysts: tariff risk not materializing immediately reduces pressure on its European robot lawn mower business, while the 618 data provides evidence of improving demand and product mix. By contrast, although Roborock still has category share advantages, full 618 data has not yet been disclosed, so Citi continues to relatively prefer Ecovacs.

Risks

• A global macroeconomic slowdown and weaker consumer spending could suppress demand for robotic home appliances.
• New product launches falling short of expectations could weaken sales growth and valuation support.
• Intensifying industry competition, especially price competition, could affect margins.
• Higher tariffs between China and destination countries could hurt export businesses.
• Significant RMB appreciation could affect export profitability.
• Raw material costs above expectations could drag on gross margins.

What to watch

• The EU's final ruling in the anti-dumping investigation into Chinese robot lawn mowers, expected around early 2027.
• Whether Ecovacs' subsequent 618 and quarterly sales data continue to validate premiumization and multi-category growth.
• Whether Roborock discloses performance for the full 618 cycle, and changes in its share gap versus Ecovacs.
• Demand trends in China's premium robot vacuums, window-cleaning robots, and floor washers.
• The impact of tariffs, exchange rates, and raw material costs on margins.
