What is the best Shark robot vacuum? Here are my top 3 picks after testing at home.

Shark vacuums shine at spot cleaning, but have a big blind spot

Scheduled full-room cleanings are a huge part of the convenience of a robot vacuum. The other half has to do with unexpected messes that need to be dealt with right now with as little clicking around in an app as possible.

In my at-home testing, Shark robot vacuums are extremely straightforward and reliable spot cleaners. Setting a zone for a one-time clean in the Shark app is as black and white as dragging a square in the designated spot cleaning tab.
