Cover Control Plus is InSinkErator's answer for buyers who specifically want batch-feed safety: the disposer only runs when the magnetic cover is locked in place. It pairs that mechanism with the full Evolution-series 3/4 HP MultiGrind chamber and SoundSeal insulation, making it the quietest premium batch-feed unit reviewers found. Worth the upcharge for homes with small children.

How the Magnetic CoverStart Works
The defining feature is the magnetic cover that doubles as the activation switch. Drop scraps into the chamber, drop the cover into the sink flange, and rotate it a quarter-turn until the magnet aligns with the sensor inside the housing. The disposer powers up only when alignment is confirmed. Remove the cover and the motor stops immediately. There is no wall switch wiring required, which simplifies new installs in kitchens that did not previously have a disposer or eliminates an unused switch in retrofits.
Reviewers consistently frame this as a meaningful safety upgrade. Family Handyman's coverage emphasized that magnetic cover start activation means it runs only when the cover is on, which is beneficial if you're concerned about children accidentally activating it. Garbagewastedisposal.com called the covered-only system meaningful safety, particularly for homes with children, and noted the cover also dramatically reduces splash escape during operation. The safety benefit also covers adult use cases: utensils or rings accidentally dropped into the chamber cannot trigger the disposer because the cover must be removed to retrieve them, and the disposer will not start until it is re-seated.
Grinding Performance and Real-World Use
Under the cover sits a standard Evolution-series 3/4 HP Dura-Drive induction motor with 2-stage MultiGrind technology and a 40 oz stainless steel chamber. Performance therefore tracks closely with the Evolution Compact for grind speed and output fineness, with the added benefit of the larger chamber. Reviewers describe it as handling common food waste with ease, processing vegetable scraps, leftovers, and small bone fragments smoothly.
The functional difference versus continuous-feed Evolution units shows up on cleanup volume rather than grind quality: batch loading is inherently slower because you load, cover, run, uncover, reload. For a single dinner cleanup this is invisible. For a Thanksgiving-scale prep session it adds five to ten minutes of accumulated load-and-cover cycles.
Noise Level and Vibration
The Cover Control Plus ships with the same SoundSeal Technology stack as the continuous-feed Evolution models: insulation blanket, anti-vibration mount, anti-vibration tailpipe, and Quiet Collar sink baffle. Reviewers describe the result as notably quieter than older entry-level disposers, with the cover itself adding a small additional damping effect against splash and chamber resonance.
Garbagewastedisposal.com noted the grinding noise remains moderate, allowing conversation to continue without major interruption. The sound profile is deeper and more controlled than that of standard disposals. For households where the disposer sits under an open-plan island, the noise floor is genuinely livable.
Build Quality and Materials
Stainless steel grind components and a 40 oz stainless chamber give the Cover Control Plus the same corrosion resistance as the top-tier Excel. The cover itself is engineered as a wear part: the magnetic alignment surface and the silicone splash seal both see daily use. Owners on Home Depot report several years of normal cycling before any cover wear becomes apparent, with replacement covers available from InSinkErator.
The chassis is taller than the Compact (closer to 15 inches with the cover-engagement housing on top of the chamber), so under-sink clearance is worth verifying before purchase.
Installation Difficulty
Mounting hardware is the standard InSinkErator 3-Bolt Lift & Latch system, so swap-outs from any older InSinkErator unit (including the legacy Cover Control or Cover Control Plus) are straightforward. The hardware difference is the lack of a wall-switch hookup; the activation logic lives entirely in the cover-sensor assembly, which means new installs skip a step but retrofits leave an unused switch in the wall (most owners cap it off or repurpose for under-cabinet lighting).
Cord is sold separately, same as other Evolution units. Budget $15 for the CRD-00 cord kit or hardwire per local code.
What Reviewers Loved
The safety case is the headline. Multiple reviews (Family Handyman, garbagewastedisposal.com, Consumer Reports) call out the magnetic cover as the load-bearing reason to buy this unit over the continuous-feed Compact. Beyond safety, reviewers consistently note the same noise floor and grind-quality benefits the broader Evolution range delivers.
Home Depot product reviews emphasize how much quieter the unit feels compared to older, entry-level disposers, with several owners specifically calling out that the cover system felt more thoughtful in a kid-busy kitchen.
Where It Falls Short
Two genuine complaints recur. First, batch feeding takes longer than continuous-feed at scale. For households running the disposer in big single sessions, this adds time. Second, some owners report that the lid gets stuck and is difficult to start, even with regular cleaning. The cover is engineered to require a precise magnetic alignment, and food residue on the alignment ring can cause partial engagement that registers as unsafe and refuses to start. Cleaning the silicone seal weekly addresses this for most owners.
The premium price (roughly $50 more than the comparable Evolution Compact 3/4 HP) buys the safety mechanism rather than any grinding-performance upgrade. Buyers who don't need batch-feed safety should consider the Compact instead.
Who It's Best For
Cover Control Plus is the right pick for households with small children where push-to-start safety is a real concern, for homes where multiple users share the kitchen and a stray utensil into the disposer is a genuine risk, and for buyers who simply prefer the cleaner deck of a no-wall-switch install. The combination of premium grinding performance and batch-feed safety is rare in this segment.
It is the wrong pick for solo cooks and couples without safety concerns who would benefit more from continuous-feed speed (the Evolution Compact), and for budget-conscious households where a Waste King L-8000TC delivers most of the batch-feed safety story for roughly half the price.
How It Compares to Alternatives
Against the InSinkErator Evolution Compact 3/4 HP, Cover Control Plus adds the magnetic CoverStart mechanism, a slightly larger chamber, and roughly $50 to the price. Against the Evolution Excel 1 HP continuous-feed, Cover Control Plus trades the third grind stage and continuous-feed throughput for batch-feed safety at roughly $110 less. Against the Badger 5 1/2 HP, Cover Control Plus more than doubles the motor power, adds full SoundSeal insulation, and bundles the magnetic cover safety for more than twice the price.
Value at This Price
At roughly $269 street, Cover Control Plus prices the safety mechanism at about $50 over the comparable continuous-feed Compact and gives buyers the rest of the Evolution-line performance and warranty package. For households where batch-feed safety is the actual buying criterion, the math is straightforward. For others, the Compact does the same grinding for less money.
Real-estate context matters here too: kitchens being remodeled for resale in markets with high young-family demand can justify the upcharge as a feature buyers actively look for. For owner-occupants, the value is determined entirely by whether the household genuinely benefits from the cover-locked safety.
Long-Term Durability
The 7-year We Come To You warranty covers parts and labor with a manufacturer technician dispatched to the home, the same arrangement as the Excel. Owners on Home Depot routinely report 10+ year service lives on Cover Control units, with the cover assembly being the most-replaced wear part rather than the motor or chamber. Replacement covers are stocked by InSinkErator and major retailers and run roughly $30-40.
The magnetic sensor inside the housing is sealed against splash and has no moving parts beyond the activation switch itself. Failures here are rare and generally tied to silicone-seal degradation on the cover rim, which interferes with the magnetic alignment. Weekly wipe-down of the cover and flange ring eliminates most reported activation-flakiness complaints. For a unit positioned squarely around a safety mechanism, the long-term reliability of the activation system itself is unusually strong, which justifies the warranty length and the price premium for households where the safety case is the actual reason for purchase.

- +Full SoundSeal Technology insulation, anti-vibration mount, and Quiet Collar baffle keep operation conversational
- +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
- −Batch loading is slower than continuous-feed for big cleanup sessions
- −Cover requires precise alignment to engage the magnetic switch; some owners report cover-stuck issues that need cleaning
- −Premium price for a 3/4 HP unit, driven mostly by the safety mechanism rather than grinding performance
How it compares
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.
Who this is for
At a glance: Households with small children where push-to-start safety matters more than throughput speed, and noise-sensitive open-plan kitchens that want the quietest batch-feed disposer available.
