Teendow D20S Max+ Robot Vacuum

Mostly. In most pet homes the D20S Max+ keeps shedding under control, but in one it pushed dog hair around hard floors and dropped clumps on carpet. The 3-liter self-emptying bag takes care of volume, so the weak spot is pickup on bare floors rather than capacity.

Reliable in most homes. Room maps, no-go boundaries and schedules in the app are easy to set up, though in one home the D20S Max+ had to be remapped every few days before it stopped missing a step edge. Check its map after the first few runs and add a boundary at any drop it misses.

It works from the dock. The handheld hose and grooming attachments get regular use for brushing dogs and clearing litter spills, but only while the Teendow is docked and the dock is plugged in. Loose fur goes straight into the dustbin, so brushing and cleanup happen in one step.

Not easily. Replacement dust bags, rollers and brushes are hard to source, and in one case the robot became hard to keep running without them. Before buying the D20S Max+, check that bags and brushes are in stock, and order spares early rather than waiting for the originals to wear out.

Not really. At 22.1 lb it's awkward to carry upstairs, though anti-drop sensors keep it from falling down the steps once it's there.
