eufy
Anker's home brand. Sits at the entry end of every category it enters, and the cheap machines are also the simple ones. Support runs as a manufacturer RMA, and retired models lose parts quickly.
eufy’s first robot vacuums traded mapping and app control for a body thin enough to clear a sofa, and the low end of the line still sells on exactly that. Consumables are stocked well while a model is current and thin out fast once it is replaced.
