What reviewers found
Grillbot Automatic Grill Cleaning Robot
- TechHive: Cleaned months of baked on residue from a 36 in built in gas grill, but brass bristles missed the bottom of thick grates, needing a flip and a second 30 minute run, and it struggled on a griddle without crossbars. Source
- Trusted Reviews: After a 30 minute clean the grill looked about as clean as 2 minutes with a metal scouring pad; it drove off a lidless grill and would not fit under a small grill lid. Verdict: a total waste of money. Source
OtO Smart Sprinkler
- The Smart Home Hookup: Three cup tests averaged 47 percent distribution uniformity, with some spots getting over 4 times the water of nearby ones; a quarter inch run took 1 hr 48 min. Reviewer said it fundamentally fails as a sprinkler. Source
- Bob Vila (3.5/5): A month of testing in southern Ohio: easy setup, ran daily at 6 a.m. in hot weather and skipped watering during a rainy week. Source
