Why do Eufy OMNI C20 and S1 Pro have the highest scores for the noise level in the comparison?

Thank you for being so interested. The noise level is important for user comfort and not to disturb pets, kids, and neighbors. A robot with a low noise level can work at night without waking the owners. For comparison, 60 dB is the noise of standard normal conversation and background music, and 80 dB is the noise of a subway. So, Eufy S1 Pro and Eufy Omni S20 are very comfortable to use because of their noise level. Only premium brands have such a noise level.

When is the best time to buy a robotic vacuum cleaner?

Thanks for bringing this up. The best time to buy home appliances is during sale events. The most popular events are Black Friday, Cyber Monday, and Christmas and New Year's Holiday Sales. Also, many brands offer significant discounts on models from previous sales during and before the release of new products. We recommend creating an Amazon price alert on the selected models or analyzing our price chart; as you can see, some brands have additional discount days without connection to any event.

Please provide more detailed information about the all-in-one stations of these Eufy robots – C20 OMNI and S1 Pro OMNI.

Thank you for asking. I am glad to provide additional information about Eufy's all-in-one stations. Eufy C20 has the size of an all-in-one station, 12.99 x 11.38 x 18.11 inches, while the S1 Pro station is thinner, 15.08 x 18.39 x 26.4 inches. They both perform several functions for hands-free cleaning – auto-emptying robot’s dust bin and storing the dust for up to 60 days (C20) and for up to 68 days (S1 Pro), auto washing and drying of washing pad, and clean water refill. After cleaning the washing pad, all dirt water is stored in the dirty water tank of both stations.

S1 has an advanced design; in addition to all these features, the clean water tank produces the ozonated water, removing all contaminants, and can automatically mix the water with the ideal amount of hard floor detergent. These stations have a detachable base for manual maintenance. All functions of both stations are performed when the robot returns to the station.

I could not find information about the quantities of mopping pads and the navigation system of the Eufy Omni S1 Pro in your comparison.

Thank you for your question. You couldn’t find information about the mopping pads of Eufy Omni S1 Pro as it has a washing rotating roll (length 11.4 inches) instead. The mopping system of this robot consists of several stages – scrape-off dirt, removal of dirt into a separate dirty tank, refresh mopping roll with clean water and detergent. The roll is constantly rolling with a speed of 170 RPM and 1 kg pf download pressure. The navigation system of Eufy Omni S1 Pro is based on LiDAR technology to create real-time 3D maps. It also uses infrared imaging technology and an RGB camera to identify various objects.

Why does the Eufy Omni C20 charge so fast?

Thanks for your interest. I am glad to answer your questions. The charging time of the Eufy C20 is significantly less than that of the Eufy S1 Pro as its battery capacity is almost twice less, which corresponds to 2.8 hours of charging time for the Eufy Omni C20. During the cleaning cycle, the robot automatically returns to the all—in—one station if the battery level decreases to less than 15%. After recharge, the robot will resume. So, the low capacity of the battery impacts only the quantity of recharge cycles.

What is the difference in the design of the OMNI station of Eufy C20 and S1 Pro?

Great point, thanks. The OMNI station of the Eufy S1 Pro is much higher and thinner than the C20. But the functionality of both stations is close. Both have dirt, clean and sealed water tanks, and a dust bag. The design of these stations does not impact the functionality. I prefer the elegant design of the Eufy OMNI S1 Pro.

Which Eufy model is better for a two-store house?

Thank you for the question. Eufy S1 Pro and C20 can create detailed maps of several floors and ensure comprehensive cleaning of all floors. However, the robots can climb the stairs, so you need to take the robot to the required floor for cleaning. Also, do not forget that the robot will have a docking station only on one floor, and it can’t return to it if it is on another floor.
