This thing is AMAZING! I’ve been curious about it since I saw it win the best innovation award at CES 2025. I was initially worried that it’d be a “jack of all trades but master of none” but fortunately, it excels at everything it sets out to do! In robot mode, it’s quiet, the mapping is precise, and with 8000pa of max suction, it has the performance of vacuums that cost MUCH more! In handheld/stick vacuum mode the main motor unit detaches and because it no longer has to power a bunch of wheels, sensors, lasers, etc… the motor gains the ability to vacuum with 30,000pa of max suction because of the additional battery power, which is AMAZING! the amount of deep cleaning it can do in handheld mode is truly impressive! The included stick vacuum brush roller attachment is pretty nice, though it lacks any hair removal tech, and the tools for handheld mode are decent and get the job done. My only real complaints would be things on the software side: such as the side brush running a bit too slow, and the auto empty base only sucking out the system for a short while, when I feel if it ran a bit longer, it would clean everything out just a little better. I’m still very happy with the auto empty feature though, as it gets 99% of the dirt out of the main unit, it just misses a bit on the stage1 filter because the base only empties for 30seconds or so. If truly ran for a full minute like it says it should in the app, I’m sure all the dust would be cleaned out. Because these are small issues that could easily be resolved with a minor software update, I’m not retracting any points though, but I will be submitting recommendations to Eufy, whenever they ask my opinions. Overall, the E20 is a FANTASTIC robot that gives an insane value for the money! The main vacuum unit has suction that rivals a Dyson V8, yet that same unit clicks into the robot to give you auto performance that’s on par with some $1000+ dedicated robot vacuums! It really IS the best of both worlds, and so long as you don’t need an auto mop, I see no better value in the vacuum world than this! The only questions I have for now are 1: durability, as it SEEMS to be well built but only time will tell, and 2: long hair management, as currently both myself and my dog have short hair that’s easy for the vacuum, so I don’t know how well the detangle comb on the robot brush roller actually works, but if anything happens in the future I’ll have to update this review. 5 stars for now though!
