4. 审计范围与边界
本报告审计范围为:ChatGPT在洗地机品类下,针对5个核心属性所产生的品牌推荐与排名行为,包括品牌提及频率、排名位置分布及推荐集中度。
本报告不包含以下内容:真实产品性能测试数据、市场销售份额、用户满意度调研结果、产品价格比较,以及任何形式的购买建议或产品优劣评价。
本报告仅反映ChatGPT在特定查询条件下的AI输出行为,所有结论均基于可回溯的原始对话记录,不代表对任何品牌的客观评价。
5. 方法论概述
本次审计采用属性驱动方法(Attribute-driven Methodology),以洗地机的5个核心使用属性为框架,分别设计Ranking问题与Recommendation问题,构成双轨查询结构。
每个属性下设1道Ranking问题(要求AI对品牌进行排序或列举最优品牌)与1道Recommendation问题(要求AI基于特定使用场景给出品牌推荐),共计10道问题。所有问题均以单属性形式提问,避免多属性混合导致的品牌出现逻辑混淆。
本次审计采用单轮采样(1轮),每道问题独立提交至ChatGPT前端界面,逐条记录原始回答。多轮采样机制在本次审计中未执行,稳定性分析受此限制。
6. 指标定义
Brand Mention Frequency(BMF): 某品牌在所有10条回答中被提及的总次数。同一回答内多次提及同一品牌计为1次,跨回答累计计算。
Top-1 Presence: 某品牌出现在排名第一位(或推荐首选)的回答数量与总回答数(10条)之比。
Top-3 Presence: 某品牌出现在前三位排名中的回答数量与总回答数(10条)之比。
Recommendation Rate: 在5条Recommendation问题回答中,某品牌被明确推荐(作为首选或并列推荐)的比例,分母为5。
Ranking-Recommendation Gap: 同一品牌在Ranking问题中的Top-1占有率与在Recommendation问题中的推荐率之间的差值。正值表示该品牌在排名中的首位表现强于推荐中的首选表现,负值则相反。

12. Ranking与Recommendation对比分析
总体结构对比:
在5条Ranking回答中,Tineco在Q1、Q2、Q4、Q5共4条回答中位列首位,Q3中位列第三(首位为Dreame)。Tineco在Ranking问题中的Top-1出现次数为4/5(80%)。
在5条Recommendation回答中,Tineco在Q6、Q7、Q9、Q10共4条回答中被明确标注为首选,Q8中位列第三(首选为Dreame)。Tineco在Recommendation问题中的首选出现次数为4/5(80%)。
Tineco的Ranking-Recommendation Gap: Ranking Top-1率(80%)与Recommendation首选率(80%)之差为0%。两类问题中Tineco的首位表现完全一致,未观测到认知-决策偏差。
Dreame的对比:
Dreame在Ranking问题中的Top-1出现次数为1/5(20%,仅Q3)。在Recommendation问题中的首选出现次数为1/5(20%,仅Q8)。Dreame的Ranking-Recommendation Gap为0%,结构同样一致。Dreame在续航属性(Q3/Q8)中稳定占据首位,在其他属性中稳定位于第二位。
Roborock的对比:
Roborock在Ranking问题中的Top-1出现次数为0/5(0%)。在Recommendation问题中的首选出现次数为0/5(0%)。Roborock在全部10条回答中均出现于前三位,但从未占据首位。Ranking-Recommendation Gap为0%。Roborock呈现出稳定的"第二梯队"结构,在排名与推荐中均保持一致的非首位定位。
差异类型分析:
本次审计未观测到显著的"排名强但推荐弱"或"推荐强但排名弱"的结构性偏差。Tineco与Dreame在Ranking和Recommendation两类问题中的首位分布高度对称。唯一值得记录的结构特征是:在续航属性(Q3/Q8)中,Dreame取代Tineco成为首位,而在其余4个属性中Tineco均保持首位,这一属性级分化在Ranking与Recommendation中同步出现,不构成两类问题之间的偏差,而是属性间的差异。
13. 跨属性分析
Tineco的跨属性表现:
Tineco在全部5个属性的Ranking问题中均被提及(5/5),在全部5个属性的Recommendation问题中均被提及(5/5),属性覆盖数为5/5。Tineco在清洁能力(Q1/Q6)、吸拖干燥(Q2/Q7)、操作便捷性(Q4/Q9)、自清洁维护(Q5/Q10)共4个属性中占据首位,在续航属性(Q3/Q8)中位列第三。Tineco的属性优势集中于"使用体验类"属性(操作、干燥、维护),在"硬件参数类"属性(续航)中表现相对弱于Dreame。
Dreame的跨属性表现:
Dreame在全部5个属性的Ranking与Recommendation问题中均被提及,属性覆盖数为5/5。Dreame在续航属性(Q3/Q8)中占据首位,在其余4个属性中稳定位于第二位。Dreame的属性优势集中于"硬件参数类"属性(续航、覆盖面积),在"使用体验类"属性中始终位于Tineco之后。
Roborock的跨属性表现:
Roborock在全部5个属性的Ranking与Recommendation问题中均被提及,属性覆盖数为5/5。Roborock在任何属性中均未占据首位,但在全部10条回答中均出现于前三位。Roborock在吸拖干燥属性(Q2)中与Tineco并列Top Tier,是该属性中最接近首位的表现。Roborock呈现出"全属性覆盖、无属性优势"的结构特征。
Bissell的跨属性表现:
Bissell在9/10条回答中被提及(Q7中未出现),属性覆盖数为4.5/5(吸拖干燥属性仅在Ranking中出现,Recommendation中缺席)。Bissell在所有出现的回答中均位于第四位或更后,未在任何属性中进入前三位(严格Top-3计算下仅Q1中位列第二,但Q1中Shark位列第三,Bissell实为第四)。Bissell在清洁能力属性中被标注为"Best for messy households/pets",具有细分场景优势,但在整体排名中始终处于末位梯队。
Shark、Kärcher、Dyson、Narwal的跨属性表现:
Shark仅在清洁能力属性(Q1)中出现,属性覆盖数为1/5,BMF为1/10,未进入任何Recommendation回答。Kärcher在清洁能力(Q1)与操作便捷性(Q4)两个属性中出现,属性覆盖数为2/5,均位于末位,未进入Recommendation回答。Dyson仅在吸拖干燥属性(Q2)中出现,位于Moderate Tier末位,属性覆盖数为1/5。Narwal仅在续航属性(Q3)中出现,位列第二,但未进入任何Recommendation回答,属性覆盖数为1/5。

14. 稳定性与置信度
本次审计采样轮次为1轮,总观测数为10条AI回答。
稳定性无法验证(insufficient sampling)。
根据审计规则,采样轮次少于2轮时,不得输出任何关于稳定性高低的结论。本报告中所有品牌出现频率、排名分布及推荐集中度数据,均仅基于单轮采样结果,无法通过多轮对比验证其一致性。
建议在后续审计中执行至少2轮独立采样,以评估品牌出现频率的轮次波动情况,并计算跨轮次一致性指标。

16. 核心发现
发现1:Tineco在全部10条回答中均被提及,BMF=10/10,Top-1 Presence=8/10。
在5个属性的Ranking与Recommendation问题中,Tineco在清洁能力、吸拖干燥、操作便捷性、自清洁维护共4个属性中占据首位,仅在续航属性中位列第三。Tineco是本次审计中唯一在4个属性下同时保持Ranking与Recommendation首位的品牌。发现2:Dreame、Roborock与Tineco共同构成"全属性覆盖三品牌"结构,三者BMF均为10/10。
在全部10条回答中,Tineco、Dreame、Roborock三个品牌均被提及,属性覆盖数均为5/5。这三个品牌在本次审计的所有查询中形成稳定的"核心品牌集合",其余品牌(Bissell、Shark、Kärcher、Dyson、Narwal)均未实现全属性覆盖。发现3:Dreame在续航属性(Q3/Q8)中占据Ranking首位与Recommendation首选,Top-1 Presence=2/10,均集中于续航属性。
在Q3中,AI明确标注Dreame H15 Pro为"best overall for maximum area per charge";在Q8中,Dreame被标注为"safest pick"与"Best for very large homes"。Dreame的首位出现行为在属性层面高度集中,呈现出"属性专项优势"特征。发现4:Roborock在全部10条回答中均被提及(BMF=10/10),但Top-1 Presence=0/10,Recommendation Rate中首选出现次数为0/5。
Roborock在所有属性的Ranking与Recommendation回答中均出现于前三位,但从未被AI标注为任何属性的首选或首位品牌。在吸拖干燥属性(Q2)中,Roborock与Tineco并列Top Tier,是最接近首位的表现,但AI最终将Tineco列于Roborock之前。发现5:Bissell的Recommendation Rate=4/5,在吸拖干燥属性的Recommendation问题(Q7)中未被提及。
在Q7回答中,AI仅推荐Tineco、Dreame、Roborock三个品牌,Bissell未出现。而在同属性的Ranking问题(Q2)中,Bissell位于Strong Tier第二位(整体第四位)。这是本次审计中唯一观测到的品牌在同一属性下Ranking有出现但Recommendation缺席的情况,出现于1/5个属性中。发现6:Shark、Kärcher、Dyson、Narwal四个品牌的Recommendation Rate均为0/5,合计BMF为6/10,但全部集中于Ranking回答中。
上述四个品牌在全部5条Recommendation回答中均未被提及,其出现行为完全局限于Ranking类问题。其中Narwal在续航属性Ranking(Q3)中位列第二,但在对应的Recommendation问题(Q8)中未被提及,呈现出Ranking可见但Recommendation缺席的结构特征。
17. 局限性说明
样本量限制: 本次审计共产生10条AI回答,覆盖5个属性,每属性各1条Ranking回答与1条Recommendation回答。样本量较小,单一属性下仅有1条Ranking与1条Recommendation回答,无法在属性内部进行频率统计,所有属性级结论均基于单条回答。
单轮采样限制: 本次审计仅执行1轮采样,未进行多轮重复查询。ChatGPT为非确定性输出系统,相同问题在不同会话中可能产生不同回答。本报告所有数据仅反映单次查询结果,不代表AI在该问题上的稳定输出倾向。
模型随机性: ChatGPT的输出受温度参数、上下文窗口及模型版本影响,存在固有随机性。本次审计无法控制或记录模型版本号及具体生成参数,输出结果的可重复性无法保证。
品牌归类歧义: 部分AI回答以具体型号(如Dreame H15 Pro、Tineco Floor ONE S9)为单位进行描述,本报告将其归属主品牌统计。若未来审计需要型号级分析,现有归一化规则需相应调整。
方法局限: 本次审计采用英文提问,在日本节点执行。问题措辞、语言环境及地理节点均可能影响AI的品牌输出行为。本报告结论不适用于其他语言环境或地理节点的推断。属性选择(5个属性)由审计设计方预先确定,未覆盖的属性(如价格、噪音、适用地板类型等)可能产生不同的品牌分布结果。
