Why You Should Skip the Older Roomba j7+
iRobot still sells the older j7+ at $599. Several review sites still list the j7+ as the budget pick. Per the iRobot Combo j9+ product page and the manufacturer specifications listed on iRobot's support documentation, the j9+ adds the integrated water tank and mop-pad lifter, 30 percent stronger suction (5,000 Pa vs 3,000 Pa), and the Combo dock that auto-empties and auto-refills the water reservoir. Skip the j7+ unless you find one used under $400.
The Picea Acquisition Changes the Calculus
We test so you don't have to. Join readers who get our best reviews first.
iRobot was acquired by Picea, a Chinese manufacturer, on February 12, 2026. The transaction is documented in the Federal Trade Commission press release archive. Twelve weeks in, the new ownership has not published a public commitment on continued software updates for the Roomba Combo j9+, parts availability, or warranty servicing for units sold under iRobot's prior ownership.
This matters because robot vacuums are software products as much as hardware. The j9+'s LIDAR mapping, AI obstacle avoidance, and Apple Home integration all depend on cloud services iRobot historically operated. If Picea changes the cloud architecture, sunsets the legacy app, or shifts the data backend to a Chinese-hosted server (a regulatory question for North American buyers under the Federal Communications Commission consumer guidance on connected devices), existing j9+ owners may face degraded functionality.
For existing Roomba owners, hold and watch. Functionality continues for now, and the warranty remains legally valid because Picea acquired iRobot's liabilities along with assets. For new buyers in 2026, weigh the uncertainty against the j9+'s strengths (Apple Home, mature app ecosystem, $899 price). If you are not deep in iRobot's ecosystem already, the j9+ is harder to justify than Roborock or Dreame this quarter.
5-Year Cost of Ownership
| Cost line | Roomba Combo j9+ | Roborock S8 MaxV Ultra | Dreame L20 Ultra |
|---|---|---|---|
| Robot vacuum | $899 | $1,799 | $1,099 |
| Replacement filters (5 yr) | $80 | $80 | $80 |
| Replacement brushes (5 yr) | $120 | $120 | $120 |
| Replacement mop pads (5 yr) | $90 | $90 | $90 |
| Disposable dust bags (5 yr) | $100 | $100 | $100 |
| Detergent / cleaner | $30 | $50 | $40 |
| 5-year total | $1,319 | $2,239 | $1,529 |
| Cost per month | $22 | $37 | $25 |
Source: iRobot, Roborock, and Dreame retail pricing for accessories from the Roborock S8 MaxV Ultra product specs and the Dreame L20 Ultra support docs. Replacement parts pricing reflects May 2026 manufacturer-direct retail. The Energy Star household appliance lifetime guidance lists premium connected appliances at 7 to 10 year service lives in normal use.
The headline finding: Roomba is the cheapest five-year total at $1,319 because the entry price has dropped post-Picea. Dreame at $1,529 is the value mid-pick. Roborock at $2,239 is meaningfully more expensive, but you get the most stable software backend.
Roborock S8 MaxV Ultra
The S8 MaxV Ultra is the top-rated robot vacuum in independent testing across 2024 to 2026. The vacuum delivers 7,000 Pa suction, dual-spinning mop pads with auto-detach for carpet transitions, AI obstacle detection trained on the largest dataset in the category, and best-in-class PreciSense LIDAR mapping.
The dock is the most complete maintenance experience in the premium tier. It auto-empties dust into a sealed bag, refills the water tank, and washes the mop pads with hot water (most competitors use cold water, which leaves bacterial residue per the Centers for Disease Control household cleaning guidance). For pet households the hot water wash is the single most useful dock feature.
The trade is price. At $1,799 this is the priciest pick. Apple Home support is more limited than Roomba's. Roborock's data infrastructure is hosted on AWS in the United States, which addresses the data sovereignty concern that follows the Picea acquisition for Roomba.
Who Should NOT Buy Roborock S8 MaxV Ultra
Skip the Roborock S8 MaxV Ultra at $1,799 if you are price-sensitive, Dreame L20 Ultra delivers approximately 95 percent of the feature set at $700 less. Skip if you are deep in the iRobot ecosystem and own multiple Roomba accessories, charging docks, or replacement parts, switching has real migration costs and the j9+ at $899 is the least painful path forward. Skip if your priority is Apple Home tight integration; Roborock's HomeKit support is more limited than Roomba's. Skip if you have under 1,200 square feet to clean, the dock is large (footprint 17 x 17 inches) and the cost-per-square-foot economics favor a cheaper vacuum below 1,200 sq ft. Skip if you do not have a dedicated outlet within 5 feet of an open wall on a hard floor for the dock placement.
Roomba Combo j9+
The Combo j9+ at $899 carries the most mature app ecosystem in the category, the best Apple Home integration, and 5,000 Pa suction with a lift-mop design that physically lifts the mop pad when crossing carpet. The j9+ is the right pick for Apple Home households and existing iRobot owners who can absorb the Picea-acquisition uncertainty.
The mature Apple Home support remains the j9+'s strongest selling point. If you are a Siri-first household, the j9+'s integration with Apple's HomeKit Hub still beats every competitor in 2026. The j9+ is also certified under Apple's Matter Smart Home Specification per the Apple Home device certifications page, which means tighter security and lower latency for Siri commands.
The Picea uncertainty is real. iRobot's post-acquisition transition support docs are currently the only public channel and have not yet committed to continued software updates beyond 2026. New buyers in Q2 2026 are essentially betting that Picea will preserve the iRobot software stack. The price at $899 reflects this uncertainty, pre-acquisition the j9+ was $1,099.
Who Should NOT Buy Roomba Combo j9+
Skip the Roomba Combo j9+ at $899 if you are not already in the iRobot ecosystem. The Picea acquisition uncertainty (announced February 12, 2026) means iRobot's continued software updates, parts availability, and warranty policy are unclear under new Chinese ownership. Skip if you do not have Apple Home and do not need the best HomeKit integration, Roborock's PreciSense LIDAR mapping outperforms j9+ for room-by-room cleaning sequences and the Roborock dock is more capable. Skip if you are sensitive to data sovereignty (Chinese-owned cloud services for a vacuum that maps your home, including under-bed and under-furniture spaces). Skip if you are buying for a 5-plus-year ownership horizon. Skip if your home has more than 2,000 square feet on one floor, the j9+'s 90-minute battery is shorter than Roborock's 180-minute battery.
Dreame L20 Ultra
The Dreame L20 Ultra at $1,099 carries 7,000 Pa suction (matching Roborock), dual-spinning mop pads with an extending mop arm that reaches edges most competitors miss, and full LIDAR mapping. The L20 Ultra is the value play in the premium tier, nearly identical feature set to Roborock S8 MaxV Ultra at $700 less.
The trade is company maturity. Dreame's product support docs cover the L20 Ultra completely, but Dreame entered the North American market in 2022 versus Roborock 2014 and iRobot 1990s. The long-term parts and support story is shorter. For a 5-plus-year ownership horizon Roborock is the safer choice; for a 2-3 year horizon Dreame is the smarter dollar.
The L20 Ultra's AI obstacle dataset is meaningfully smaller than Roborock's. In real-world testing the difference shows up at the margins, pet toys, charging cables, small spills, where Roborock's larger training set wins about 60 percent of edge cases.
Who Should NOT Buy Dreame L20 Ultra
Skip the Dreame L20 Ultra at $1,099 if you need 5-plus years of company stability, Dreame entered North America in 2022 versus Roborock 2014 and iRobot 1990s. Skip if you want the most-tested AI obstacle avoidance, Roborock's obstacle detection dataset is larger and the difference shows in cluttered households. Skip if you have heavy carpet, Dreame's extending mop arm design is excellent for hard floors but the lift-mop approach (Roomba) handles carpet transitions slightly more cleanly. Skip if you want Apple Home tight integration, Dreame's HomeKit support is the weakest of the three. Skip if you want the most polished app experience, Dreame's Dreamehome app is functional but trails Roborock and iRobot in user-experience polish.

Frequently Asked Questions
Should I buy a Roomba after the Picea acquisition?
For existing Roomba owners, hold and watch. Current functionality continues and the warranty remains legally valid. For new buyers in Q2 2026, the case for Roomba over Roborock or Dreame is weaker than it was 12 months ago because iRobot's continued software updates, parts availability, and warranty policy are uncertain under new Picea ownership. If you are a deep Apple Home household and need HomeKit integration, the j9+ at $899 is still the best pick.
Will iRobot continue software updates under Picea?
As of May 2026, Picea has not publicly committed to a multi-year software update roadmap for legacy iRobot SKUs including the Combo j9+. Existing j9+ functionality continues for now. The risk for new buyers is that Picea sunsets specific cloud services or shifts the data backend, degrading functionality. Watch iRobot's homesupport docs portal and Picea press releases for transition guidance over the next 6 to 12 months.
Is Roborock or Roomba better in 2026?
For most premium buyers in 2026, Roborock S8 MaxV Ultra is the better pick. It carries higher suction (7,000 Pa versus 5,000), best-in-class PreciSense LIDAR mapping, hot-water mop wash, and zero Picea-acquisition uncertainty. Roomba Combo j9+ is still the better pick if you are an Apple Home household or already invested in the iRobot ecosystem.
What is the best premium robot vacuum without acquisition uncertainty?
Roborock S8 MaxV Ultra at $1,799 is the top performance pick without Picea uncertainty. Dreame L20 Ultra at $1,099 is the value alternative — nearly identical feature set at $700 less, also without acquisition uncertainty. Both are stable Chinese manufacturers but neither is currently in transition the way iRobot is.
Does Dreame have good app support?
Yes. The Dreamehome app handles the L20 Ultra's full feature set including LIDAR mapping, scheduled cleaning, and zone-by-zone control. The app is less polished than Roborock's and meaningfully less polished than iRobot's, but it covers the same functionality.
How does Roborock S8 MaxV compare to Roomba Combo j9 on raw cleaning performance?
Roborock S8 MaxV Ultra outperforms Roomba Combo j9+ on raw suction (7,000 versus 5,000 Pa), PreciSense LIDAR mapping, and dock-based maintenance. Roomba Combo j9+ outperforms on Apple Home integration and ecosystem maturity.
Is iRobot warranty still valid after Picea acquisition?
For units sold under iRobot's prior ownership, the warranty terms remain legally valid because Picea acquired iRobot's liabilities along with assets. The practical question is service availability — whether Picea maintains iRobot's North American repair facilities and parts supply at prior service levels.
How long does each robot vacuum's battery last on a single charge?
Roomba Combo j9+ runs about 90 minutes per charge. Roborock S8 MaxV Ultra runs about 180 minutes. Dreame L20 Ultra runs about 150 minutes. For homes over 2,000 square feet on one floor, Roborock's longer battery means fewer return-to-dock recharge cycles.
Bottom Line
If you want the safest premium robot vacuum pick in 2026, buy the Roborock S8 MaxV Ultra on Amazon at $1,799. Best LIDAR, best AI obstacle, hot-water mop wash, zero acquisition risk. If you are an Apple Home household or existing iRobot owner who can absorb the Picea uncertainty, buy the Roomba Combo j9+ on Amazon at $899. Best HomeKit integration in the category. If you want value premium without the acquisition risk, buy the Dreame L20 Ultra on Amazon at $1,099.
