Buy the Tikom G8000 Max Robot Vacuum.

It does the whole job for a third of the price, and does it more reliably.

What was compared

1. One robot that mops, not just vacuums
Tikom is built as a vacuum and mop combo, cleaning hard floors and lifting stains in the same pass. The Shark AV2501S is vacuum only, so you still need a separate mop for spills and grime.
2. Owners say Shark's robots break, Tikom outlasts
Research consensus flags Shark's robot vacuum line as widely disliked for unreliability, while a three-dog Tikom household reports it outlasting and outperforming four other vacuums over a year.
3. Struggles with the exact job it is sold for
Research on the Shark AV2501S notes it struggles to clear pet hair on high-pile carpet, the very job most buyers want it for. Tikom owners with multiple pets report solid pickup of fur and debris on the same kinds of floors.
4. Nearly three times the price for the same job
$149.99 against $429.00 is a huge gap for two robots doing the same basic vacuuming job, and Tikom throws in mopping the Shark does not have at all. That price buys the exception, not the rule, of what most homes need.
5. Yes, it empties itself. That's not the whole story.
The Shark's 30-day self-empty base is a real convenience, but research says rivals feel better built with fewer parts to clean. Unless emptying a bin once a week is a dealbreaker for you, that added complexity is not worth the extra cost, and we do not think that is most people.
