My picks for the best smart dishwashers split into two clear groups: compact models that fit small homes and a built-in option for a full kitchen. The GE Profile Countertop Dishwasher is my lead pick for flexible installation and app features, while the SPT SD-6505SS suits buyers who want a full-size built-in machine with automatic cycle selection. For renters or RV owners who need a water tank, the BLITZHOME Portable Countertop Dishwasher offers a distinctly more self-contained setup.

The central tradeoff is capacity versus installation freedom. The SPT holds up to 12 place settings but needs a built-in space. The GE and BLITZHOME models take smaller loads, yet can work in spaces where a conventional dishwasher is impractical. I rank these by how well their smart features support their intended use, then weigh capacity, setup flexibility, drying, noise, and the compromises buyers should expect.
Complete the kit
Key Takeaways
- The GE Profile is the most adaptable compact pick: it supports countertop, built-in, or under-sink installation and connects to SmartHQ for cycle customization, monitoring, and alerts.
- The SPT SD-6505SS is the only full-size built-in option here, with 12 place settings and Smart Wash cycle selection; it needs permanent installation and is rated at 54 dB.
- The BLITZHOME is the strongest fit for spaces without a dependable faucet hookup because its five-liter tank can supply water, though its compact load size calls for frequent runs.
- App features differ: GE offers cycle customization and alerts, BLITZHOME provides status checks and timer control, and SPT’s smart function selects a wash cycle based on load and soil level.
- For a small kitchen, compare the GE’s quieter 52 dBA rating and flexible installation with BLITZHOME’s tank-based water supply and the SPT’s much larger capacity.

More Details on Our Top Picks
GE Profile Countertop Dishwasher with WiFi
The GE Profile earns my Best Overall spot because it offers the broadest installation choices in this lineup while retaining meaningful app control. It can be used on a countertop, built in, or under a sink, and an included unicouple supports faucet hookup. That combination makes it more adaptable than the SPT, which is a built-in model, and more suitable for a lasting kitchen setup than the BLITZHOME when a buyer wants options beyond a countertop footprint.
Its SmartHQ connection supports cycle customization, status monitoring, and alerts. Those controls are more expansive than the BLITZHOME’s stated status checks and timer setting, while the SPT’s described intelligence is centered on choosing a wash cycle based on load and soil level. The GE’s six cycles and six-place-setting capacity place it in the compact category: it can serve a small household, but it cannot match the SPT’s stated 12-place capacity for larger batches.
The listed 52 dBA noise rating is lower than the SPT’s 54 dB and BLITZHOME’s 58 dB, a useful distinction in an open-plan apartment or kitchen close to living space. Auto Open Dry adds a drying feature without relying solely on a heated-dry description. GE is also ENERGY STAR certified, and the manufacturer says it uses over 75% less water than handwashing. I would treat that as a manufacturer comparison rather than a universal guarantee, since actual use depends on how dishes are washed and the selected cycle.
Its main appeal is flexibility, not sheer volume. A six-place-setting appliance needs more frequent runs than the SPT for family-size dish loads, and buyers should check that their chosen installation arrangement fits their cabinetry and hookup. Compared with BLITZHOME, the GE is the stronger pick for buyers who want app alerts and several installation paths; BLITZHOME remains the more fitting choice when a built-in water tank is the deciding convenience.
Pros:- Three listed installation options offer more placement flexibility than the SPT built-in.
- SmartHQ supports cycle customization, status monitoring, and alerts.
- Rated at 52 dBA, quieter on paper than the other two options in this roundup.
- ENERGY STAR certified, with Auto Open Dry and an included faucet unicouple.
Cons:- Six place settings provide much less capacity than the SPT’s 12.
- The supplied specifications do not state its water capacity or dimensions, so buyers should confirm fit and hookup details before purchase.
Best for: Apartment dwellers or small households who want app monitoring and the option to install a compact dishwasher on a counter, under a sink, or in a built-in arrangement.
Not ideal for: Households that routinely generate large dish loads, or buyers who need the listed five-liter built-in water tank rather than a faucet hookup.
- Installation options:Countertop, built-in, or under-sink
- Capacity:6 place settings
- Wash cycles:6
- Connectivity:Built-in Wi-Fi; SmartHQ app
- Noise level:52 dBA
- Efficiency:ENERGY STAR certified
- Drying:Auto Open Dry
- Included accessory:Unicouple for faucet hookup
Our verdict“I recommend the GE Profile for compact kitchens that need installation flexibility, connected controls, and a quieter stated operating level, provided six place settings are enough.”
SPT SD-6505SS 24-Inch Built-In Stainless Steel Dishwasher
The SPT SD-6505SS is my Best Full-Size Built-In pick. Its 12-place-setting capacity is double the GE Profile’s stated six settings and substantially beyond the BLITZHOME’s compact 4–6-setting description. For a household that has room for a standard built-in dishwasher and wants to handle more dishes per run, that capacity matters more than countertop portability.
SPT’s smart feature works differently from the app-connected GE and BLITZHOME models. Its Smart Wash system selects a cycle based on the load and soil level, which can reduce the need to choose among programs manually. The supplied description does not list Wi-Fi or phone-app functions, so buyers looking for phone alerts or remote monitoring should compare it with the GE. The machine instead focuses on automatic cycle selection and conventional dishwasher features, including five listed programs, delay start, and a sanitize option.
Rack layout gives it a practical advantage over the compact alternatives. An adjustable upper rack and top cutlery rack provide dedicated space for utensils and some flexibility for loading dishes. Heated drying is included, and the optional auto-opening door offers another drying approach. These features make the SPT more appropriate for an established kitchen than either countertop model, but a built-in unit requires a suitable opening and installation. Its 54 dB rating is higher than GE’s stated 52 dBA, though lower than BLITZHOME’s 58 dB as listed.
The tradeoff is a narrower role: capacity and built-in convenience come at the expense of portability and the app controls described for the other picks. Its listed water capacity is seven gallons, and buyers should compare that figure with their usage needs rather than assume it will match the compact machines’ water consumption. I place it second because it is the strongest full-size option here, but the GE remains the better overall fit for shoppers prioritizing setup flexibility and connected monitoring.
Pros:- 12-place-setting capacity exceeds both compact models’ stated capacities.
- Smart Wash selects a cycle based on load and soil level.
- Adjustable upper rack and top cutlery rack help accommodate varied dishes and utensils.
- Includes heated drying, optional auto-opening door, delay start, and sanitize option.
Cons:- Built-in installation is less flexible than either countertop option.
- Its listed 54 dB noise level is above the GE Profile’s 52 dBA rating.
- The product details provided do not describe Wi-Fi or app controls.
Best for: Households with a suitable built-in kitchen opening that want a 12-place-setting machine, load-responsive cycle selection, and a top cutlery rack.
Not ideal for: Renters without installation permission, buyers needing a portable or tank-fed appliance, or shoppers who specifically want app-based remote monitoring and alerts.
- Model:SD-6505SS
- Installation type:Built-in
- Capacity:12 place settings
- Wash programs:Normal, Auto, Quick, Rinse, Heavy
- Water capacity:7 gallons
- Noise level:54 dB
- Dimensions:22.7 × 23.6 × 33.75 inches
- Certification:ENERGY STAR
Our verdict“I’d choose the SPT when full-size capacity and automatic cycle selection matter more than portability or phone-based controls.”
BLITZHOME Portable Countertop Dishwasher with Wi-Fi
The BLITZHOME is my Best for Tank-Fed Portability pick. Its most distinctive feature is not the app: it can draw water from a built-in five-liter tank or connect to a tap. That gives it a practical role for a small apartment, dorm, boat, or RV where plumbing changes or a permanent dishwasher opening are not realistic. The GE also supports a countertop setup and includes a faucet unicouple, but the supplied GE details do not list a built-in tank. When a buyer needs an onboard water supply, BLITZHOME has the clearer advantage.
For a compact appliance, it offers six wash programs: Standard, Quick, Strong, ECO, Fruit, and Drying. App and touch controls provide status checks and timer setting. Compared with GE’s SmartHQ features, the listed app functions are more limited: GE specifies cycle customization and alerts, while BLITZHOME emphasizes checking status and setting a timer. SPT’s Smart Wash takes another approach by choosing a cycle based on the load and soil level, and its built-in format supports twice the stated place settings.
The BLITZHOME description lists approximately 4–6 place settings, a compact capacity suited to smaller daily loads rather than a busy household’s accumulated dishes. Dual spray arms, high-temperature washing, and drying are among its stated features. At 58 dB, its listed noise rating is higher than both the GE’s 52 dBA and the SPT’s 54 dB. Buyers placing the machine close to a dining or sleeping area may prefer the quieter GE if they can use its hookup arrangement.
Its strength is making dishwashing possible where a standard machine does not fit, with a water-supply choice that the other descriptions do not provide. Its limits are equally clear: small capacity and phone-dependent remote controls narrow the audience. I would choose it over the GE when the tank is essential, but choose the GE for quieter operation, broader described app controls, or multiple listed installation formats.
Pros:- Built-in five-liter tank or tap connection offers a water-supply choice.
- Six programs cover standard, quick, strong, ECO, fruit, and drying needs.
- Compact countertop design can suit spaces without a built-in dishwasher opening.
- Dual spray arms and high-temperature washing and drying are listed features.
Cons:- The stated 4–6 place settings may require frequent cycles for larger households.
- At 58 dB, its listed noise level is higher than the GE and SPT ratings.
- Remote controls rely on the phone app.
Best for: One- or two-person households, renters, dorm residents, RV owners, or boat owners who want a compact dishwasher with a built-in water tank or tap connection.
Not ideal for: Families or frequent entertainers who need larger loads, and buyers who want smart controls without relying on a phone app.
- Installation type:Countertop
- Capacity:Approximately 4–6 place settings
- Water supply:5-liter built-in tank or tap connection
- Wash programs:6: Standard, Quick, Strong, ECO, Fruit, Drying
- Noise level:58 dB
- Dimensions:17 × 16.9 × 18.1 inches
- Weight:26 pounds
- Controls:App and touch control
Our verdict“I recommend BLITZHOME when tank-fed countertop use solves the installation problem, and would skip it if capacity or quieter operation comes first.”
How We Picked
I compared the three supplied models against the needs implied by smart dishwasher: useful connected or automatic functions, practical cleaning capacity, and a setup that makes sense for the buyer’s home. A Wi-Fi label alone does not make a dishwasher a strong recommendation. I looked at what each smart feature actually does and whether it helps with cycle choice, checking progress, scheduling, or installation.
For ranking, I gave weight to useful flexibility and the match between features and the intended household. The GE takes the first position because its three listed installation options pair with app cycle customization, status monitoring, and alerts, plus a comparatively quiet stated noise rating. SPT comes next for buyers who need a conventional built-in machine: it has the largest stated capacity and a load-responsive Smart Wash system, though it offers less setup flexibility and no described app controls. BLITZHOME is third overall because its tank-or-tap water supply is valuable for portable living, but its smaller capacity and app-dependent remote functions make it a more specific choice.
I also considered drying, noise, and stated efficiency details where supplied. I have not treated unprovided features as absent, nor inferred performance beyond the product descriptions and specifications in this comparison. Where a manufacturer makes a claim, such as GE’s water-use comparison with handwashing, I identify it as the manufacturer’s claim. None of the supplied materials establishes independent test results, so my recommendations focus on the listed features, dimensions of fit, and disclosed tradeoffs.

Factors to Consider When Choosing Best Smart Dishwashers
I would start with the kind of dishwasher setup your home can support, then compare capacity and smart functions. These three picks serve different jobs: a full-size built-in, a flexible compact model, and a tank-fed portable option.Choose installation before comparing apps
A built-in dishwasher makes sense when your kitchen has a suitable opening and the installation can be completed. In this group, that is the SPT SD-6505SS. The compact models offer different ways to work around limited space: GE lists countertop, built-in, and under-sink options, while BLITZHOME is a countertop unit that can use its own tank or connect to a tap. The GE includes a faucet unicouple. Before choosing, check the product’s installation instructions and confirm the required clearances and hookup arrangement for your home.
For renters, RVs, boats, and dorm rooms, the key question is how water reaches the appliance and whether the location can support its drain and power needs. The BLITZHOME tank is especially relevant when a faucet connection is inconvenient. The product details supplied here do not specify every setup requirement, so confirm the manufacturer’s directions for the exact space and connection you plan to use.
Match capacity to the dishes you actually generate
The SPT leads on stated capacity at 12 place settings. That makes it the natural comparison point for a family or anyone who prefers fewer, larger loads. GE lists six place settings, while BLITZHOME is described as holding approximately four to six. Those compact capacities can suit one or two people, but they may mean running the machine more often when cookware, serving dishes, or a full day’s dishes accumulate.
Capacity labels do not tell the whole loading story. Rack layout and dish dimensions affect what fits together. SPT specifies an adjustable upper rack and a top cutlery rack. For either compact model, check whether your regular plates, cups, and cookware fit the interior before buying; the supplied product details do not provide a full loading diagram for either one.
Look for smart functions that save effort
“Smart” describes different benefits across these models. GE’s SmartHQ app supports cycle customization, monitoring, and alerts. BLITZHOME’s app provides status checks and timer control. SPT’s Smart Wash selects a cycle based on load and soil level, while its supplied description does not mention a phone app. Decide whether you want remote visibility, more control from a phone, or less manual cycle selection.
Connected features depend on the app and home network working as expected. If phone control is central to your choice, verify app compatibility and setup requirements with the manufacturer. If you prefer not to depend on a phone, compare the controls available on the appliance itself; BLITZHOME specifically lists touch controls, and SPT describes automatic cycle selection.
Compare drying and noise for your room
Drying options vary. GE lists Auto Open Dry; SPT includes heated drying and an optional auto-opening door; BLITZHOME lists drying as one of its six programs. These descriptions do not establish identical drying results, so consider the drying method that suits your routine and check product guidance about dishes that should not be exposed to heat or automatic door opening.
The stated noise levels are 52 dBA for GE, 54 dB for SPT, and 58 dB for BLITZHOME. The GE has the lowest listed figure, a useful point for a kitchen close to living or sleeping areas. Ratings may use different measurement conventions, so treat the numbers as a guide rather than a direct guarantee of how loud a particular installation will sound.
Read efficiency claims in context
Both GE and SPT are listed as ENERGY STAR certified. GE’s manufacturer says the machine uses over 75% less water than handwashing. BLITZHOME lists five liters of water consumption, while SPT lists a seven-gallon water capacity. Those figures may describe different measures or operating contexts, so they should not be treated as a direct apples-to-apples comparison without cycle-specific documentation.
If water use is a deciding factor, check the current model documentation for consumption by cycle and the conditions behind any comparison with handwashing. The number of dishes washed in each run and how often you run the appliance also affect household use.
Frequently Asked Questions
Which smart dishwasher in this roundup is best for an apartment?
For an apartment with limited space, I would compare the GE Profile and BLITZHOME. GE offers countertop, built-in, and under-sink installation options and includes a faucet unicouple, while BLITZHOME has a five-liter tank as well as a tap connection. Choose GE if its installation arrangement works and you want SmartHQ cycle customization and alerts; choose BLITZHOME if tank-fed operation is the deciding feature. Both have much smaller stated capacities than the SPT built-in.
Which model has the largest capacity?
The SPT SD-6505SS is listed for up to 12 place settings, compared with six for GE and approximately four to six for BLITZHOME. It is the strongest fit when you want to handle larger batches in a full-size built-in machine. That capacity comes with a more fixed installation, so a small kitchen or rental without an appropriate opening may be better served by one of the countertop options.
Do all three dishwashers have Wi-Fi or app controls?
No. GE and BLITZHOME list Wi-Fi or app-based functions: GE’s SmartHQ app supports cycle customization, monitoring, and alerts, while BLITZHOME’s app supports status checks and timer control. SPT describes a Smart Wash system that selects a cycle based on load and soil level, but the supplied details do not mention Wi-Fi or an app. I would verify current connectivity requirements with the manufacturer if app control is a must-have.
Which option is best when there is no convenient water hookup?
BLITZHOME is the clearest choice for that situation because its built-in five-liter tank can supply water, and it also supports a tap connection. GE includes a faucet unicouple, but its supplied specifications do not list a tank. Installation and drainage still matter for any portable dishwasher, so check the manufacturer’s directions for your intended counter, sink, RV, boat, or dorm setup.
Which dishwasher is likely to be the quietest?
GE has the lowest stated rating at 52 dBA, followed by SPT at 54 dB and BLITZHOME at 58 dB. That makes GE the first one I would examine for an open-plan room or a kitchen near a sleeping area. Because the descriptions use dBA and dB for different listings and installation can affect perceived sound, compare the product documentation and treat the figures as a guide rather than a guarantee.
Conclusion
For a small household that wants flexible installation and app alerts, I recommend the GE Profile Countertop Dishwasher. Choose the SPT SD-6505SS if your kitchen has a built-in opening and you value 12-place capacity and automatic cycle selection. Pick BLITZHOME if a countertop unit with a built-in water tank solves a hookup problem in an apartment, dorm, RV, or boat. The right choice depends on what your space can support and how many dishes you need each run to handle.
