Detailed Reviews

This one surprised me with how well it handles deep carpet cleaning. The smart mapping learns your home layout, so it’s not bumping around randomly like older models, which is a feature discussed in our Robot Vacuum Buying Guide 2026.

  • Can be noisy on high power settings

Best For: Anyone with extensive thick carpeted areas who doesn’t mind paying premium for top performance.

Roborock S7+

The S7+ packs serious suction power—actually higher than the Roomba—and adds sonic mopping. The combo approach works well if you have mixed flooring.

Key Specs:

  • Suction Power: 2500 Pa

Shark IQ Robot Vacuum R101AE

Here’s where things get interesting. At half the price of the Roomba, the Shark IQ delivers surprisingly good carpet performance. The self-cleaning brush roll is genuinely useful for pet hair.

Neato D8

The D-shaped design isn’t just for show—it actually gets into corners better than round vacuums. Strong suction makes it solid for thick carpets, but you’ll be emptying it manually.

Key Specs:

  • Suction Power: 2000 Pa
  • Battery Life: 120 minutes
  • Self-Emptying Bin: No
  • Room Size: Up to 2000 sq. ft.

  • No self-emptying feature
  • Can be noisy

Best For: Pet owners who need superior hair pickup from thick carpets and don’t mind manual emptying.

Eufy RoboVac G30 Edge

I’d skip this unless you’re on a tight budget. It handles light carpet cleaning okay but struggles with deeply embedded dirt in thick carpets.

Key Specs:

  • Suction Power: 1500 Pa
  • Battery Life: 100 minutes
  • Self-Emptying Bin: No
  • Room Size: Up to 1500 sq. ft.

Pros:

  • Affordable and efficient
  • Smart navigation for systematic cleaning
  • Compact design fits under furniture

Cons:

  • Less powerful suction for deeply embedded dirt
  • No self-emptying feature

Best For: Light carpet cleaning on a budget—honestly, save up for something more powerful if you have thick carpets.

How We Evaluated

I tested these vacuums on several criteria:

  1. Performance on Thick Carpets: How well each vacuum lifted dirt and debris from various carpet types, especially thick and plush options.
  2. Noise Level: Nobody wants a vacuum that sounds like a jet engine.
  3. Filter Cost and Maintenance: Ongoing costs and how annoying upkeep becomes.
  4. Room Size Capability: Whether each vacuum can handle your space efficiently.
  5. Value for Money: Features versus price—some expensive models aren’t worth it.

Buying Guide

Here’s what actually matters for thick carpet cleaning:

  • Suction Power: Aim for at least 2000 Pa, which is a key point discussed in our How To Choose A Robot Vacuum. Anything less struggles with thick carpets.
  • Navigation Technology: Smart mapping beats random bumping around every time.
  • Self-Emptying Capability: Worth it if you have pets or don’t want constant maintenance.
  • Battery Life: Make sure it covers your cleaning area without dying mid-job.
  • Filter Quality: HEPA filters help with allergens but aren’t essential for everyone.

FAQ

1. Can robot vacuums clean thick carpets effectively? Yes, but only the more powerful models, as detailed in our post on Do Robot Vacuums Work On Carpet. Budget options often just push dirt around on thick carpets.

2. How often should I run my robot vacuum on thick carpets? 2-3 times a week minimum. Thick carpets trap more dirt, so they need more frequent cleaning.

3. Do robot vacuums scratch hardwood floors? Modern ones have soft wheels and sensors to prevent scratching. Check reviews for any specific issues.

4. Are self-emptying robot vacuums worth the investment? Absolutely, especially with pets. Manual emptying gets old fast.

5. How do I maintain my robot vacuum? Clean brushes weekly, empty the bin regularly, and replace filters as needed. It’s not complicated.

Conclusion

The iRobot Roomba s9+ wins for thick carpets—it’s pricey but actually works. If you want to save money, the Roborock S7+ offers more suction for less cash, while the Shark IQ provides decent performance at half the price.
