eufy G30 Robot Vacuum (Open Box)

I first bought the 11S Max. Was terrible experience. It banged into everything! Couldn't follow a wall. Maybe a bad unit. Eufy has good reputation so proceeded on my search. Then decided on self emptying. It is a game changer! The C10 is a newer model and so incredible. It talks to inform you of cleaning, finishing, emptying/ self cleaning and charging cycles so you know exactly what it is doing. If you need to locate it, it literally plays a musical melody. The rotating brush literally is on an arm that will extend from unit to get corners and spaces while cleaning and under furniture. Most robots have fixed brushes. (The brush fell off the 11S Max!). The C10 rarely bumps into anything. It's initial mapping still seems to be spot on for thorough cleaning. It gets into/under the tightest spaces but it always seems to find it's way back out. It's only got stuck once. You can pick different power cleaning modes and I chose standard. It is plenty and keeps the noise level down. I have plank flooring and area rugs and the 'boost' feature seems to be plenty for robot to climb onto rugs. I've opened the dust bin and filtet to check (curious) and this self cleaning mode works! In the brief attempt to use the 11S Max, I had to manually dump dustbin and clean filter. The Eufy does capture a lot, even the fine dust. I keep a clean house but was amazed at the fine dust this captured. My cat's eyes showed great improvement just within 1 week! She has extreme allergies. So if you're on the fence about the C10 being worth $100 more, it is. The C10 will alert when dustbag needs replacing. I've since learned other self emptying robots make you have to manually check a dustbag?! That leads to unnecessary exposure of dust to remove a bag to check how full. Defeats the whole purpose of self-contained dust collection! For those with allergies I'm sure I don't need to explain how significant this C10 feature is! The C10 is exceptional for the price point. Amazon has the best price. I've never owned a Robot vacuum before. Researched brands and affordable price points. I was hesitant at first to spend another $100 over the S11 Max and other similarly-priced robot vacuums but it was the best decision ever.
