iRobot Roomba 208 Combo vs iHome AutoVac Nova S1 Pro

The iHome AutoVac Nova S1 Pro is the better buy for most people: LiDAR mapping, room-specific cleaning, virtual boundaries and a self-emptying dock are features the Roomba 208 lacks.

On price, the Nova S1 Pro hit $87 at its lowest on October 31 and $199 at its highest on November 2; the Roomba 208 has only been seen at $169 on October 28.

What reviewers say

iRobot Roomba 208 Combo

  • 4.6 / 579 ratings

With 79 ratings averaging 4.6 out of 5, buyers are broadly positive, though the sample is small. The dust compactor and combo cleaning draw the most favorable comment.

What people mention
  • Dust compactorPraisedOwners like that it compacts debris so it needs no dock.
  • MoppingMixedThe mop works, but the 0.2 L tank runs dry on larger floors.
  • BatteryPraisedThe long runtime covers big rooms on one charge.
  • MaintenanceCriticisedWithout a dock, emptying and refilling are hands-on chores.

iHome AutoVac Nova S1 Pro

  • 3.7 / 52,011 ratings

Ratings average 3.7 out of 5 across roughly 2,000 reviews, so reception is mixed. Owners like the hands-off self-emptying and app control but report shortcomings in suction and durability.

What people mention
  • Self-emptyingPraisedOwners like that the base empties the bin so they go weeks without touching dust.
  • SuctionCriticisedReviewers say 2,700 Pa handles hard floors but leaves debris on plush carpet.
  • MappingPraisedLiDAR mapping and room-specific cleaning are called useful and accurate.
  • AppMixed
