eufy BoostIQ RoboVac 30 (Open Box)

** Update 5/1/21 ** I wrote the below review over a year ago and downgraded it in January due to failures of the brush fan motors, and the complete inability to buy new ones. Anker has since put replacement parts for sale online here: https://us.eufylife.com/collections/accessory, and you can now replace all the key modules that might fail over time (short of an accident, this will likely just be the motor assemblies). The motors use plastic gears, and the gears will inevitably fail after a year or so of daily use, which is kind of frustrating given the high quality of everything else about this machine. However, I can forgive that now that replacement parts are readily available and easy to swap out. The drive wheels (with motors) are easy to swap. The other motors and gears are easy--but require complete complicated disassembly that may be tricky for most consumers. ANKER--you have disrupted the robot vacuum market from iRobot's monopolistic overpricing with smaller, cheaper, and beloved little Eufy machines, I have restored my 5 star rating now that replacement parts are offered, and because of the fantastic customer service offering replacement parts if appropriate. But--please, please redesign the gearboxes so they do not fail prematurely, this is the only blemish on an otherwise fantastic product! ** Original Review ** I LOVE my Eufy Robovacs. I have 3 of them, purchased maybe 9 months ago. Two of them are this 30 model, basically identical to my other 35C model but without Wifi. I never use the Wifi, but the important kicker is if you don't get one of those models you can only run these manually (which is what we do upstairs so we can control the timing), or by setting up a scheduled time to run every day. So, these guys run EVERY day in my basement and first floor, and the house is impeccably clean now. It's really addictive to live in a clean house, but be warned that this is addictive--I can never go back to manually vacuuming when I think "it's time to clean", which turns out to mean the floor was dirty most of the time. These things really really work well, trust me the negative reviews you may see are just the competition spamming Eufy for having a better product, bad luck, or a hater. Here is what I've learned: - It's finally time to buy a robot vacuum cleaner. The price is finally low enough (be sure to use their coupons!), and they work. - Eufy improved on what iRobot pioneered. Never mind all the technical bells and whistles of the Roomba product line, they are all too big to work as well as the Eufy. These things go under most furniture and clean everywhere, no more dust bunnies under the bedroom furniture and china hutch. - Eufy is in 2nd generation and the sensors are not as advanced (e.g., no mapping yet). Don't worry about it, their software is so smart that uses pre-wired cleaning patterns in combination with the simple sensors and with randomness and 100+ minutes per day of run time it gets >95% of the floor perfectly clean each day. Yes, I look forward to the smarter generations coming, but these work really well, and the short size, suction, run time, and price are far more important than a competitor's claims about sensors. - You can buy replacement parts pretty cheap on Amazon (3rd party ones seem to work fine). - Life with Eufy means the house is always clean, all you need to do is dump out the dust bin about weekly (easy to check if it's full), and keep the roller brush free of hair and carpet fibers by cleaning that--for me that's every 2-3 weeks. Perhaps monthly seems fine to clean the actual filter. Everything is super easy and well designed. - You do need to "Eufy proof" your house so it can clean, it will get stuck on the end of a cord, string, etc. - It goes up and down over things surprisingly well, and almost never (like 5 times out of 270 days) gets stuck on the long strings on the end of my huge oriental carpet. - It will occasionally get stuck in some crazy situation--it beeps for help, and goes to sleep if you don't save it. There is a particular rocking chair whose base is a Eufy trap (like 1 time in 10). - Eufy customer support is really fast and great. I had a drive wheel go bad on one of them, and they identified the problem and sent me a new wheel under the 1 year warranty. Replacement took 5 minutes with a screwdriver, now it works fine again. It appears that you can buy all the parts cost effectively if this happens out of warranty. I hope this helps someone, these are great products and I'm happy to be in the new age of clean living!
