## Product: iRobot Roomba j9+
**Brand:** iRobot

Yes, the [iRobot Roomba j9+](https://shopsavvy.com/products/HUSOWHflMsPLEUv9IqFo) excels on carpet, including medium and high-pile rugs. It's particularly effective for homes with pets.

## Key Carpet Features

**Automatic Carpet Boost**
The j9+ detects carpet transitions and automatically increases suction power—no manual adjustment needed.

**6000 Pa Suction**
With 100% stronger suction than the Roomba i-series, the j9+ extracts deeply embedded dirt and pet hair from carpet fibers.

**Tangle-Free Rubber Brushes**
Dual multi-surface rubber brushes agitate and lift debris without wrapping up in hair like traditional bristle brushes.

## Performance Results

- **99% debris removal** on carpeted surfaces
- Effective cleaning in corners and along edges
- Smooth transitions between hard floors and rugs

## Advanced Features for Carpets

**Dirt Detective:** Learns which rooms need more attention and automatically schedules deeper cleaning.

**Multi-pass cleaning:** Can be set to vacuum the same area twice for heavily soiled carpets.

## Considerations

| Factor | What to Expect |
|--------|----------------|
| Noise | Louder on carpet due to boosted suction |
| High-pile rugs | Very thick shag (>0.75") may slow the robot |
| Dark carpets | Occasional cliff sensor confusion (rare) |

## The Bottom Line

The j9+ ranks among the best robot vacuums for carpet cleaning, especially in homes with shedding pets. The combination of automatic boost, powerful suction, and tangle-free brushes makes it well-suited for mixed-flooring homes.
