What to know before connecting the Roborock S8 MaxV Ultra to your drainage system

One of the coolest features of the Roborock S8 MaxV Ultra is its ability to connect to your existing plumbing. This allows it to automatically refill its clean water supply and drain its dirty water after each cleaning cycle. In other words, it turns the robot vacuum into a highly automated floor cleaner that needs little to no manual input.

The most demanding portion of owning this version of the Roborock S8 MaxV Ultra is installing it. Unlike the traditional model, which comes with water reservoirs and plugs into an electrical outlet, this model needs to connect to both your water and drain lines. And depending on how your home is set up, it might be more of a hassle than it’s worth.

Interested in learning more about the requirements for connecting the Roborock S8 MaxV Ultra to your drain and water lines? Here’s everything you need to know before making a purchase.

Roborock S8 MaxV Ultra plumbing system requirements

The Roborock S8 MaxV Ultra connected to plumbing.

Roborock lays out some pretty strict requirements for using the S8 MaxV Ultra with your plumbing system. The company asks that you reach out to its customer support team before purchasing so they can run you through all the specs, but here’s a quick look at some of the requirements:

  • Water pressure range between 0.1 MegaPascals (MPa) and 0.4MPa.
  • If pressure is above 0.4MPa, you must install a pressure-reducing valve.
  • Drainpipe diameter should be no larger than 3.3 feet, though ideally no larger than 1.6 feet.
  • The dock should be placed on a hard surface and against a wall.
  • Water refill and drainage pipes should be within 19.7 feet of the dock.

Ideally, you’ll be able to connect to the water inlet and drainpipe in a laundry room or underneath your sink. But if these locations aren’t ideal, you can also try to use a floor drain, bathroom sink, or other area that’s more accessible to your robot vacuum.

What installation gear is included with the Roborock S8 MaxV Ultra

The Roborock S8 MaxV Ultra includes many of the components you’ll need to complete your setup. The Connector Kit includes several tubes and adapters, though depending on your plumbing, you may need to run out and buy additional parts. Here’s what you’ll find inside the installation kit.

  • Harness tube
  • Tap water filter
  • Clean water three-way valve
  • Inlet pipe (0.25 inch)
  • Drainpipe (0.375inch)
  • Lock plate (0.25 inch)
  • Lock plate (0.375 inch)

Check your refill and drainage system connection

Once you think the installation is complete, you can use a self-check program in the Roborock app to determine if everything is properly connected. During this check, you should look to see if the system is filling and draining water properly, monitor for leaks, and check the overall results in the mobile app.

We’d highly recommend contacting Roborock before purchasing this version of the Roborock S8 MaxV Ultra. And if you’re not a DIY expert, it might be a good idea to talk to a local plumber to help with the installation.

SwitchBot S10 robot vacuum connects to your plumbing for fully automated mopping
The SwitchBot S10 on a white background.

IFA 2023, an annual consumer electronics show, has been filled with impressive smart home reveals, but when it comes to automated floor cleaners, few products on display were as innovative as the SwitchBot S10. Like existing robot vacuums and mops, the S10 is capable of vacuuming and mopping your floor without any manual input. The big difference, however, is the SwitchBot Floor Cleaning Robot S10 hooks up to your plumbing to perform automated water changes.

That makes the S10 the first auto-refilling and auto-draining robot mop available to the public -- which should make it an impressive rival for the Roborock S8 Pro Ultra and Ecovacs Deebot T20 Omni. SwitchBot notes that the S10 supports most existing plumbing systems, and after you’ve connected the dock to your water line and drainage pipe, all you’ll need to do is empty its dustbin every 70 days.
