Make Sure the N79S is Right for You... ECOVACS App ECOVACS App requires 2.4G Hz Wi-Fi. Please note that certain app features like virtual mapping are only available with specific ECOVACS products. Please check product description or contact our customer support team for further information. For customers who can't use the ECOVACS App or Alexa, the N79S comes with (1) traditional remote controller. Versus Traditional Vacuum Cleaner Robot vacuum cleaners do not entirely replace the need for manual cleaning and are not a complete substitute for traditional vacuum cleaners (yet). They greatly reduce the frequency and effort needed for regular cleaning. Product Maintenance For optimal performance please regularly clean the N79S. Please see the instruction manual for detail instructions on how to properly clean your N79S. The N79S comes with complimentary cleaning tools. Area Preparation Prior to cleaning, please clear the intended cleaning area of objects that can obstruct the N79S's movement including cords, wires, etc. Also note the N79S can become stuck under furniture. Floor Type For optimal performance, the N79S is best used on hardwood and tiles floors, or on light colored thin, low-pile carpets. Performance is poor when used on dark colored or thick carpets. If your home contains a large number of rugs or thick carpets, we do not recommend the N79S. Air Filtration The N79S air filtration system captures particles that are ejected into the air while it cleans, reducing the amount of airborne particles present in your home. The N79S is not a suitable substitute for a standard air filtration system. Noise Level The N79S noise level in standard suction mode is about ~67 dbA, and can reach ~70 dbA when in Max Mode. This audio level is sufficiently low that you can comfortably watch television or chat on the phone without being disturbed.
