InSinkErator Evolution 1HP Advanced Series
Ranked #2 in Best Garbage Disposals
InSinkErator Evolution 1HP Advanced Series
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 Excel 1.0 HP
Ranked #1 in Best Garbage Disposals
InSinkErator Evolution Excel 1.0 HP
1 sourceall derived

Every other 1 HP disposer chases the Excel, InSinkErator's top-of-line continuous-feed unit. Reviewers at shouldit.com, Consumer Reports and Family Handyman rank it the quietest and most thorough grinder they have tested, processing 90 oz of mixed scraps in about two minutes. Plan for the heft and the cord-kit add-on.

Strengths
  • — 40 oz stainless steel grind chamber with alloy stainless components resists corrosion and odor buildup over years of daily use
  • — Lift & Latch 3-bolt mount lets one person hang and rotate the disposer into place without a helper
  • — 7-year We Come To You in-home warranty covers parts AND labor with a manufacturer technician dispatched to your home
Watch-outs
  • — Power cord sold separately as a kit add-on
  • — Premium pricing more than triples a 1/2 HP starter unit

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 Excel 1.0 HP

Sits a clear tier above the 3/4 HP Evolution Compact in motor power and grind stages, with a 40 oz chamber against the Compact's 34.6 oz. Significantly quieter and finer-grinding than the entry-level Badger 5 1/2 HP and a meaningful step up from the 3/4 HP Septic Assist for non-septic homes that want a third grind stage.
