Price History
Price last checked Jul 2, 2026. Amazon prices change frequently — click through for the current price.
The j9+ has strong suction and smart mapping when it works, but a 25% one-star rate tells a rough story: firmware updates brick units, maps erase themselves, and pet waste avoidance misses cat vomit and piles. Self-empty is jet-engine loud, and warranty resolutions vary. Owners who get a good unit like the obstacle photos and room scheduling; owners who do not pay return shipping out of pocket.
Best for: Consider if you want premium pet suction and can tolerate occasional app babysitting; avoid if you need truly hands-off navigation or hate disposable bags and loud docks.
