# Implementation Overview

This page features an autogenerated overview of all ValetudoRobot implementations including their supported capabilities.<br/>
To find out what those do, check out the [capabilities overview](https://valetudo.cloud/pages/usage/capabilities-overview.html) section of the docs.

You might want to take a look at the [Buying supported robots](https://valetudo.cloud/pages/general/buying-supported-robots.html) and
[Supported Robots](https://valetudo.cloud/pages/general/supported-robots.html) page instead.

This is just the autogenerated overview. Keep in mind that rooting instructions will differ for each of these **or might not even be available at all**.<br/>
Just because the code would - in theory - support a Robot doesn't necessarily mean that you can simply buy it and put Valetudo on it.<br/>

Again:<br/>
This is just an autogenerated overview based on the codebase at the time of generation.<br/>
Don't take this as "Everything listed here will be 100% available and work all the time".<br/>
