About This Vacuum
The iRobot Roomba j9+ Self-Emptying Robot Vacuum delivers 100% stronger suction than previous Roomba i-series models. Dual rubber brushes and adjustable cleaning power lift embedded pet hair from carpets and sweep daily debris on hard floors. The self-emptying base station handles dirt disposal for weeks between empties. PrecisionVision Navigation uses advanced sensors to map your home and avoid obstacles like cords, shoes, and pet toys. Dirt Detective, powered by iRobot OS, learns from past cleaning sessions to automatically prioritize dirtier rooms and adjust suction, scrubbing intensity, and cleaning passes. The robot gets smarter over time, customizing each cycle to your home's needs. Pet owners get the P.O.O.P. (Pet Owner Official Promise) guarantee: the robot avoids pet waste, or iRobot replaces your unit for free. The j9+ handles daily maintenance and scheduled deep cleans across carpets, hardwood, and tile. The 22.6-pound base station needs a permanent spot near an outlet. Like all robot vacuums, it works best in clutter-free spaces with clear floor paths.
Frequently Asked Questions
For pet hair, look for strong suction (roughly 20,000 Pa or more on a robot vacuum, 150 AW or more on a cordless), a tangle-resistant brush roll, a dedicated pet tool, and HEPA filtration, which by definition captures 99.97% of particles at 0.3 microns. Dyson, Shark and Bissell all make well-reviewed pet models. Use the Pet Hair Specialist filter on our comparison table to see which ones are in stock and what they cost right now.
Most manufacturers suggest replacing filters every 3 to 6 months, depending on how often you vacuum and whether you have pets. HEPA filters usually last 12 to 18 months if you clean them regularly. Washable foam filters on bagless models should be rinsed every 1 to 2 weeks and dried fully before going back in. Replacements typically run $15 to $50. A clogged filter chokes airflow, so suction drops noticeably well before the filter looks dirty.
For hardwood floors, stick vacuums (like Dyson V15 or Tineco Floor One S5) or canister vacuums with adjustable suction and soft brush attachments work best. Key features to look for: rubber or felt wheels that won't scratch, adjustable suction settings, and soft roller brush heads. Avoid beater bars with stiff bristles that can scratch wood surfaces. Average price range: $200-$600 for quality hardwood-safe vacuums.
Corded vacuums offer consistent power (typically 10-12 amps) and unlimited runtime, ideal for homes over 2,000 sq ft. Average cord length is 25-30 feet. Cordless vacuums provide convenience with 20-60 minutes runtime (premium models like Dyson V15 offer up to 60 minutes). Battery replacement costs $50-$150 after 2-3 years. For quick cleanups and homes under 1,500 sq ft, cordless is often more practical. Cordless models now match corded suction power in premium price ranges ($500+).
It depends heavily on type. Budget uprights generally start around $80 to $150, mid-range stick vacuums land near $200 to $400, premium cordless models from Dyson and Shark run higher, and robot vacuums cover the widest span of all. Those bands move with sales, so treat them as orientation rather than a quote. Our comparison table shows the current price on every model we track, and you can sort by price to see where the range actually sits today.
