If you’re in the market for a robot vacuum, you could do hours of research on something that sucks up dirt, or you could choose my pick after my own hours of research, which is the Roborock S4 Max robot vacuum.

Features/Specs

From Amazon:

  • Laser Navigation, Multi-Level Mapping, Invisible Wall and No-Go Zones: Precision laser navigation provides fine control of where the robot goes across up to 4-levels.
  • 2000Pa Suction: Powerful enough to easily lift dust from floors and drag it from carpets.
  • App Control: See where S4 Max has been, a map of your home, control schedules and suction power, and more from your phone.
  • S4 Improved: Now with better carpet cleaning performance, better climbing ability and bigger dust bin.
  • Large Battery: A large battery means long cleaning times, more than enough to tackle larger homes.

My Experience

I was skeptical about robot vacuums until I moved into a larger house where I didn’t have cords and stuff laying around everywhere and decided it would make sense. I love this vacuum.

Dumb vs. Smart

There’s only so much one can say about a vacuum, but I’ll cover what you need to know: there are two levels of robot vacuums, bump-around-style and laser-style (from now on I will refer to them as “dumb” and “smart” respectively). There’s a price threshold separating the two around $200-250, dumb ones being cheaper. Dumb robot vacs wander around the house and change direction when they hit an obstacle, and you basically hope that they clean the areas you want to clean and don’t fall down the stairs. They’re okay, definitely better than nothing, but I think it’s a good idea to invest in a more effective and efficient one if you’re going to put $100+ into something. Smart robot vacs use advanced laser sensors to map out your house and plan an effective movement pattern to clean the entirety of each area of your house.

Brands

The main players right now are iRobot (Roomba) and Roborock. In general they are similar in performance at each price point, but I’ve found that Roborocks are slightly cheaper for the equivalent model (feature for feature, it’s Roborock S4 Max vs. Roomba i7). Both are easily repaired and have great reputations, although I wish the warranties were longer.

The Best Midrange Robot Vacuum: The Roborock S4 Max

The S4 Max is fantastic for a midrange unit. As mentioned above, it doesn’t get all the cat litter off my carpet, so I use my regular vacuum for that every once in a while, but that really is the only downside I’ve noticed. I also don’t think any robot vacuum would get all of the cat litter up from carpet. It’s very easy to dump out the dirt thing and the filter is washable which is very convenient. I’m impressed with its navigational abilities. It’s only gotten stuck in cords/under a rolling chair a couple times, but I would get stuck too if I were a robot vacuum in a strange human world. The robot is quiet for a vacuum, hovering around 70 db on the normal power setting:

The app is very easy to use and lets you clean specific rooms or areas easily, and shows you a cool map of where the robot has cleaned in your house. There were some issues with the app previously from what users have said, but I haven’t had any issues with the most recent version.

You could get a more expensive one that can mop, like the S5 or S6, but I wanted to get one that was focused and great at one task rather than trying to do everything and potentially not being great at both.

Does Ted Approve?

This vacuum is one of my best investments. Highly recommend!

Bonus: I found this comment on the Roomba i7 pretty cool.

Where To Buy

Usually around $380 with discount. I was able to get mine when it was briefly $330.

Other Options

  • Close enough: the iRobot Roomba i7 is usually a little more expensive for similar performance, but is compatible with their self-cleaning base that empties the robot automatically. I don’t think it’s that hard to empty out the dust cup after every clean, but users report that it is very convenient.
