Let me start by saying I have purchased no less than 5 robot vacuums over the years and every single one led to disappointment in their operation, performance, and/or features. So my expectations weren’t the highest, but I was hoping the S7 was worth the hefty price and wouldn’t be a another dud.The Roborock S7 was by far the most expensive robot vacuum I’ve ever purchased. I never went over $350.00 with my previous robot buys. But after reading reviews and specs of the S7 and comparing it to countless other vacuums for months and debating with myself about buying the S7, I felt I had researched enough and went ahead and gave it a go. Wow! I am so glad I decided on this particular robot vacuum!**************The vacuum:The suction is great and the carpet boost really helps pick up dog hair from my three large dogs that are constantly shedding around the house and on the living room rug they like to sleep on. It’s actually pretty unbelievable how well it picks up dog hair and dust/dirt off my rugs, tile, and hardwood flooring that the dogs bring in all day. I love how it is able to get under my beds, most furniture and two couches. I neglect those areas pretty frequently, so it’s nice to not worry about dog hair and dust piling up under them.The S7 is amazing when it comes to vacuuming. It is seriously efficient, you can see where and what room the robot is in via the app and the progress it is making, and they battery life while running is fantastic. Speaking of the app, It is wonderful and easy to use - I love how you can send the robot to vacuum different rooms or certain spots in the house as well as the number of times you want it to pass over the selected room/area.The no go areas and invisible wall functions work perfectly. I’ve had no issues at all setting them up and the S7 recognizes them every time.I’ve had no issues with the robot getting hung up or stuck on something while running. It’s the first robot I’ve had that didn’t need full time babysitting while it was vacuuming. The navigation and mapping of my house are both exceptional. It still runs into certain things but is able to recognize and move around the object.As soon as it has finished cleaning, the S7 will return to the base and empty itself in its bin (if you purchased the auto empty base) and start charging itself.—— Vacuum CONs:As far as my personal observations go, I can only note one con and that’s with the bags for the the auto empty dock. I wish the bags were washable and reusable. I get that the current bags are sealed and keep the dust/debris inside the bag and out of the air and off the floors, but a reusable bag would be great for some buyers who try to keep unnecessary waste to a minimum. For some, the sealed bags wouldn’t be an issue at all and could possibly be a pro. But for me, it’s a small annoyance.**************The mop:I love that you don’t have to switch out attachments between mopping and vacuuming. The S7 can mop and vacuum at the same time, which is so convenient.Mop CONS:—— You can only use water in the mop tank, which I know some buyers didn’t like because it doesn’t sanitize the floors at all. My work around is using electrolyzed water, which is as effective as bleach at killing germs. Google force of nature cleaner if you want to use water in the mop to sanitize. I’ve had no issues using electrolyzed water and it makes the house smell clean and deodorized.—— without a doubt you will still need to mop your house. The S7 is great for in-between mopping days. When it rains, my dogs track mud in onto my tile floors. The mop function isn’t going to get the mud up well enough. It will get some up, but not enough to be satisfied with the result. But it does great for very light mopping jobs and mopping under most furniture so you don’t need to move things around to mop underneath.***************Bottom Line:Seriously, I can not recommend the Roborock S7 enough. I would buy it again in a heartbeat. While it was the priciest robot vacuum I’ve ever purchased by a long shot, I’m so glad that, for me at least, it was worth getting over the price sticker shock. It performs fantastic when it comes to vacuuming and the mop function is great for light mopping between good old fashioned bucket and mop cleanings.The S7 gets a rating of 4.7/5 from me. It exceeded my expectations by a miles!
