iRobot Roomba j9+
Best for: Pet owners and busy families who want the smartest, most capable self-emptying robot vacuum
Rated 9/10 by our testing team
The Roomba j9+ is iRobot's smartest vacuum. PrecisionVision navigation identifies and avoids obstacles like pet waste, cords, shoes, and socks — critical for pet owners. Creates a complete map of your home 7x faster than the j7+. The Clean Base empties itself for up to 60 days. Smart Scrub mode presses down harder and scrubs back and forth on stubborn messes. Works with Alexa and Google Assistant for voice control.
Why we like it
- Avoids pet waste — essential for pet owners
- 60-day self-emptying Clean Base
- 7x faster mapping than previous gen
Flaws
- $899 MSRP — most expensive Roomba
- Clean Base bags are ongoing cost
- Doesn't mop (vacuum only)

Roborock S8 Pro Ultra
Best for: Homeowners who want a robot that vacuums AND mops with a fully automated dock
The Roborock S8 Pro Ultra is the most automated home cleaning robot. It vacuums with 6,000Pa suction, then mops with sonic vibration at 3,000 cycles/minute. The mop automatically lifts when it detects carpet. The RockDock Ultra does everything — empties the dustbin, washes the mop pad with clean water, and dries the mop with hot air. You literally do nothing except empty the water tank every few weeks. This is as close to a self-cleaning house as technology gets.
Why we like it
- Vacuums AND mops in one pass
- Dock: self-empty, self-wash, self-dry
- Auto-lifting mop for carpets
Flaws
- $1,600 MSRP — serious investment
- Large dock footprint
- Mop pad replacement needed periodically

iRobot Roomba j7+
Best for: Pet owners who want obstacle avoidance and self-emptying at a lower price than the j9+
Rated 9/10 by our testing team
The Roomba j7+ is the smart Roomba buy. Same PrecisionVision obstacle avoidance as the j9+ — it sees and avoids pet waste, cords, and shoes. Self-emptying Clean Base holds 60 days of debris. Imprint Smart Mapping learns your floor plan for room-specific cleaning. At its current discounted price (often $300-400 less than the j9+), it delivers 90% of the j9+ experience. The j9+ adds stronger suction and faster mapping — nice but not essential for most homes.
Why we like it
- Same obstacle avoidance as j9+
- 60-day self-emptying dock
- Significant savings vs j9+
Flaws
- Weaker suction than j9+
- Slower mapping than j9+
- No Smart Scrub feature

Roborock S8
Best for: Value seekers who want vacuuming and mopping without the premium Pro Ultra dock price
The standard Roborock S8 delivers the same 6,000Pa suction and sonic mopping as the Pro Ultra — without the all-in-one dock. DuoRoller rubber brush system prevents hair tangles (huge for pet owners). ReactiveAI 2.0 obstacle avoidance navigates around furniture and objects. Auto-lifting mop rises when it detects carpet. At under $400 (vs $1,600 for the Pro Ultra), it's the vacuum+mop combo for people who don't mind manually emptying the dustbin and rinsing the mop.
Why we like it
- Same 6,000Pa suction as Pro Ultra
- DuoRoller brush prevents hair tangles
- Fraction of the Pro Ultra price
Flaws
- No self-emptying dock
- Manual mop pad cleaning required
- No hot air drying for mop

BUYING GUIDE
Robot Vacuum Buying Guide
Self-emptying dock is the #1 feature that separates good from great — it means weeks of hands-free cleaning. Obstacle avoidance matters most for pet owners (pet waste accidents). Mopping is a bonus but won't replace a real mop for deep cleaning. For most homes, a Roomba j7+ (vacuum-only, self-emptying) or Roborock S8 (vacuum+mop, manual empty) hits the sweet spot of price and features.

iRobot Roomba vs Roborock
Roomba for the smartest obstacle avoidance and ecosystem (works with Braava mops). Roborock for vacuum+mop combos and stronger suction. Roomba Clean Base bags are an ongoing cost; Roborock dustbins are bagless. Both brands make excellent products — your choice depends on whether you want mopping built in.
