Shark robot vacuum: what each light, error and message means
SharkNinja publishes a numbered error-code list for each robot series, and some faults carry two numbers (for example ‘9, 1094’ for the dust cup). The codes here are from its list for the RV2800 series PowerDetect NeverTouch Base robots; each links SharkNinja’s own step-by-step page for that code.
Applies to the RV2800 series: RV2800ZE, RV2820ZE, RV2820ZEUS, RV2820ZECA, RV2800YE, RV2820YE, RV2820YEUS, UR2860YS, AV2810YS, RV2820YECA, UR2850ZE, UR2850ZEUS, RV2810ZE and RV2810ZEUS. Other Shark series (ION, IQ, AI Ultra, Matrix) have their own lists, and SharkNinja does not say that the numbers carry over.
