j7+ vs j9+ — is the j9+ worth the upgrade?

The j9+ has better suction and a slightly improved brush system, but most owners say the j7+ at its lower price is the better buy. The cleaning difference is marginal for most homes.

Is the j7+ still a good buy in 2026?

At sale prices under $400, yes — it's a proven, reliable robot with excellent pet hair handling. At full price, the feature gap with competitors makes it hard to recommend. The lack of mopping is increasingly a dealbreaker.

Should I get this or a Roborock Q5 Pro+?

The Q5 Pro+ has a larger dustbin (770ml), longer battery (240 min), and stronger suction. The j7+ has obstacle avoidance and the P.O.O.P. guarantee. For pet-waste-concerned households, the j7+ wins. For raw vacuuming performance and value, the Q5 Pro+ wins.

Does the obstacle avoidance work in the dark?

No — the camera needs ambient light. In completely dark rooms or under dark furniture, it can't identify obstacles. LiDAR-based robots don't have this limitation.

How long does it last?

iRobot builds durable products. Many owners report 4-5+ years of daily use. Battery replacements are available. The j7+ is expected to be supported with software updates for years to come, despite Amazon acquisition concerns.

iRobot Roomba j7+

Name: iRobot Roomba j7+
Brand: iRobot
Price: 750 USD
Availability: Discontinued

The j7+ was the default pet-owner recommendation for years, and its core strengths still hold up: PrecisionVision reliably steers around pet waste, cables, shoes, and socks, and the pet-waste guarantee behind it is unique in the industry. The dual rubber extractors remain a benchmark for pet hair — they never tangle and pop out for easy cleaning — and the compact Clean Base blends into a room far better than the bulky docks on most all-in-one systems. The value conversation has shifted, though: at full price you're buying a vacuum-only robot with a 120-minute battery when the same money now buys vacuum-and-mop combos with self-washing docks. The camera navigation also needs ambient light, so dark rooms and under-furniture zones go uncleaned, and undisclosed suction specs translate to carpet cleaning that trails LiDAR-equipped rivals. Long-term reviews are clearest on the buying advice: grab it under $400 on sale, where its proven reliability and pet-specific features make it a strong value.

Owner Insights

The Roomba j7+ is one of the most-discussed robot vacuums in owner discussions with over 6000 estimated mentions. It was the default recommendation for pet owners for years, and while newer competitors have closed the gap, it remains a popular and proven choice. The PrecisionVision obstacle avoidance is still praised as one of the most reliable implementations — it consistently avoids pet waste, cables, and shoes.

The dual rubber extractors continue to be described as the best brush system for pet hair. They never tangle, are easy to pop out and clean, and handle multi-pet households without issue. Combined with the P.O.O.P. guarantee and US-based customer support, the j7+ offers a reassurance package that no Chinese brand matches.

However, the value conversation has shifted dramatically. At its original $600 price, owners increasingly struggle to justify a vacuum-only robot without mopping when competitors offer vacuum+mop with self-washing docks for the same money. The j7+ is now most enthusiastically recommended when it drops below $400 on sale, where its proven reliability and pet-specific features make it a strong value. At full price, the feature gap with Roborock and Dreame is too wide for most buyers.

Pros

+PrecisionVision navigation reliably avoids pet waste, cables, shoes, and socks
+P.O.O.P. guarantee is unique and provides genuine peace of mind for pet owners

−Suction specs aren't disclosed — real-world carpet cleaning trails LiDAR competitors
−iRobot subscription locks some smart features behind a paywall
−Camera navigation is inherently slower and less efficient than LiDAR
−Amazon acquisition uncertainty has some concerned about long-term support
