I got this roomba back in 2017, mostly because I was lazy. I just didn’t want to vacuum but I wanted clean floors. Over the years I’ve never had to because this thing is able to work 24/7 and while this thing isn’t a A+ student in the precision department. (It will wander everywhere) The little guy WILL wander everywhere and through persistent work just clean everything, pull hair, dust and debris I didn’t even see out of god knows where.It has been doing this since November 2017, and it’s had a good run. It is t dead, no. It “should” be dead, in the years I’ve had to replace the main brush guard twice, the main brush itself three times, the side brushes once or twice each, the battery and finally the left wheel (it gave out recently) and I was able to order replacement parts on amazon for less than 35$ each.I’ve learned how to (not recommended by the manufacturer) tear this thing down safely and clean it and give it the TLC it needs, it kinda has become the equivalent of an old favorite car or bike that you just know inside and out.In its current last act it is helping as valiantly as it can to keep the flea population as low as possible (cat decided to bring friends inside and I am working furiously to keep from becoming a snack each time I sleep, putting everything through the washer, and cleaning and spraying (it’s going well). This roomba in its own would pick up a flea (which while it isn’t much in flea numbers just makes me feel more attached to this little guy).So I decided to get clever, (another process probably not recommended by the manufacturer coming btw) and out some quick drying adult, larvae and flea egg killer that lingers at the bottom of the dust collector.... let it dry and turned it on.It has been fighting its war in fleas much more effectively. Found two more on its first run and a third on its next. Running it again.So I recommend you do this? Nope! What I’m saying is this little guy has been going on for several years, has been bumped, battered and had parts broken on it and it is still running. I’ve had manual vacuums last less... and do less, although I’ve had them do more and last longer too. The main benefit of this roomba is that if you get to know it carefully and learn how to replace parts and keep it clean it can be your best friend if you like a clean house and hate bugs!The reason I am writing this review is because I’m waiting on another roomba (the a9 version of this one). Will I stop using the a4s? Nah, it will just be retired to cleaning my room only while the new kid on the block tackles the whole house.If you’ve made it this far I fully can recommend this roomba new and from the manufacturer (get it while you can!) and have had absolutely no regrets because this is probably the most sturdy roomba that is keeping a house clean that has three people with long hair, and three cats to keep up with.If you have any questions, feel free to ask. Can’t guarentee a quick response (I work like everyone else) but I’ll try and answer when I am able.
