## What reviewers found

### iRobot Roomba 105 Vac + AutoEmpty Dock

- Vacuum Wars (1.41 Vacuum Wars stars): Removed 82% of embedded sand, above the 75% average, but picked up only 29% of flattened pet hair and 79% of long hair wrapped the brush. Coverage was about 630 sq ft per charge and it has no obstacle avoidance. [Source](https://vacuumwars.com/roomba-105-vac-review-irobots-cheapest-self-emptying-robot-vacuum-in-2025/)
- RTINGS: Named the Roomba 105 its best cheap robot vacuum for smart navigation, long battery life and an optional self empty dock, but called vacuuming only adequate and obstacle avoidance weak. [Source](https://www.rtings.com/robot-vacuum/reviews/best/budget)

### MOVA E40 Ultra

- Vacuum Wars (2.92 Vacuum Wars stars): Bought and tested in house against the original P10 Pro Ultra: 88% carpet deep clean against a 77% average, but 47% flattened pet hair pickup, 44% hair tangle, 5 of 24 obstacles avoided and about 1,602 sq ft per charge. [Source](https://vacuumwars.com/mova-e40-ultra-vs-p10-pro-ultra/)
- Gizchina.it: Used for several weeks as the main home robot: mapping was quick and accurate, the app stable. In turbo mode on about 60 m2 it could drop to about 20% battery, then it recharges and resumes. Suction on long pile carpet may disappoint. [Source](https://en.gizchina.it/2026/01/recensione-mova-e40-ultra/amp/)
- SmartWorld (Italy): Cleaned 100 m2 in about 1.5 hours on just over 50% battery, climbed 2.2 cm ramps and boosted suction on rugs. Mops sometimes brushed rug edges and the drying cycle is fairly loud. Sample supplied by MOVA. [Source](https://www.smartworld.it/recensioni/mova-e40-ultra)
