1 sourceall derived$291as of Oct 17

The InSinkErator Evolution 1HP Advanced Series is a 1 HP continuous-feed disposal with a Dura-Drive motor running at 1,725 RPM, a 28.5-ounce capacity and a four-stage stainless steel grind. The Spruce names it the best garbage disposal overall, and its tester, who used it multiple times a day for more than a year, reported no jams or clogs and said it is so quiet it blends into the sound of running water. The Spruce also notes that it ships without a power cord, that its insulation makes it wider than some competitors, and that the rubber guard needs constant cleaning. It suits larger households that put a lot of food waste down the sink; buyers with cramped cabinets or narrow doors under the sink should measure first.

Strengths
  • — Very quiet: The Spruce's tester said it blends into the background once the water runs
  • — No jams or clogs after more than a year of daily use in The Spruce's tester's kitchen
  • — Four-stage grind with stainless steel components handles bones and other tough scraps
Watch-outs
  • — No power cord in the box, so a cord must be bought unless it is hardwired
  • — Extensive insulation makes it wider, which can complicate narrow cabinets or posts under the sink
  • — The rubber guard needs constant cleaning to remove food scraps
InSinkErator Evolution Cover Control Plus 3/4 HP Batch Feed
Ranked #3 in Best Garbage Disposals
InSinkErator Evolution Cover Control Plus 3/4 HP Batch Feed
1 sourceall derived

Batch-feed safety is the whole point of Cover Control Plus: the disposer only runs when the magnetic cover is locked in place. InSinkErator pairs that mechanism with the full Evolution-series 3/4 HP MultiGrind chamber and SoundSeal insulation, which makes it the quietest premium batch-feed unit reviewers found. Homes with small children will find the upcharge worth it.

Strengths
  • — Magnetic CoverStart batch-feed activation means the unit cannot run without the cover locked in place, eliminating accidental starts from dropped utensils or curious hands
  • — 40 oz stainless steel grind chamber, the largest in InSinkErator's batch-feed lineup
  • — 7-year We Come To You warranty includes parts and labor with a manufacturer-dispatched technician
Watch-outs
  • — Premium price for a 3/4 HP unit, driven mostly by the safety mechanism rather than grinding performance

How they stack up

InSinkErator Evolution 1HP Advanced Series

The Evolution 1HP Advanced Series matches the 1 HP rating of the InSinkErator Evolution Excel 1.0 HP and has twice the horsepower of the InSinkErator Badger 5 1/2 HP. Unlike the InSinkErator Evolution Cover Control Plus 3/4 HP Batch Feed, it is a continuous-feed unit, so scraps can be added while it runs.

InSinkErator Evolution Cover Control Plus 3/4 HP Batch Feed

Shares motor and chamber design with the Evolution Compact 3/4 HP, but trades continuous-feed for cover-locked batch operation and adds about 5 oz of chamber capacity. Roughly $50 more than the Compact for the magnetic safety mechanism. Quieter and finer-grinding than the Badger 5 1/2 HP but at more than twice the price; the safety mechanism is the buying reason here, not the motor specs.
