This VERY affordable square robot vacuum is a great replacement for my 4 year old iRobot. It's about the same noise level and works pretty well on my hardwood floors. It is very easy to remove the lid from the cleaning bin, take out the cleaning bin and empty the waste. Any pet hair stays on the cotton (filter) of the device, but I use a sticky roller to remove the hair. Battery life is good as it is parked and charged at the base. It's easy to set a regular schedule for when to start vacuuming, and it comes home easily. Most of my furniture is big enough to tuck under furniture, but unfortunately there are one or two items that they keep getting snagged on. Something easy to fix when I have a remote control next to me. Pick it up and go the other way if it's not too tight. So far I like the price and it's creeping into the corners of my rooms. If you don't want to pay more than $500 for a robot vacuum, this is a worthy replacement.
