iRobot Roomba j9+ vs Shark IQ Robot
Quick take: The iRobot Roomba j9+ costs $50 less; the iRobot Roomba j9+ runs longer per charge (120 vs 90 min).
Which one to buy
Shark IQ owners themselves steer buyers away from it at full price, and here it costs $50 more than the Roomba j9+. Both are camera-navigated, vacuum-only robots with self-empty bases and multi-floor maps, but the j9+ is ahead almost everywhere it counts. It has obstacle avoidance that owners say reliably skips pet waste, cables and shoes. It's rated at 120 minutes against the Shark's 90 and runs at 65 dB against 72. Its dual rubber extractors are what owners call the best brushes for pet hair.
The Shark IQ's standout is its self-cleaning brushroll, which owners agree really reduces hair-wrap maintenance. Its other praise is easy store returns and US support. The complaints are heavier: inconsistent navigation that misses spots, maps that corrupt or reset and need redoing, frequent sticking on rug edges, chair legs and low furniture, and a short battery that limits it to small homes.
The j9+ has its own camera limits. Owners say it needs ambient light, runs slower than LiDAR robots, and puts Smart Maps and Clean Map reports behind a subscription. Even so, it's the better robot at the lower price, and its pet-waste guarantee is something the Shark doesn't offer.
Buy the j9+ if you find leftover stock; both are now discontinued, replaced by the iRobot Roomba Max 715 Vac + AutoEmpty Dock at $500 and the Shark Navigator Robot Vacuum with Self-Empty Base at $280. The Shark IQ only makes sense on a deep discount for a small, simple space.
iRobot Roomba j9+
Now discontinued, but suits obstacle avoidance, quieter running, longer runtime and better pet-hair brushes, all for $50 less than the Shark IQ.
Shark IQ Robot
Now discontinued; choose the Shark IQ Robot only if you find it deeply discounted for a small, uncluttered space and want its self-cleaning brushroll and easy store returns.
