Best Portable Dishwashers That Need No Plumbing (2026)
No sink access, no faucet adapter, no plumbing — you just want a dishwasher you can fill with a jug and plug in. Six models in our database have built-in water tanks that make this possible, and most also accept a faucet hookup for permanent installation later.
We pulled every spec from the official manuals: tank capacity, water per cycle, real place settings (not the inflated retailer claims), noise, and wattage. If you're buying one for an RV, dorm, office, or rental where modifying plumbing isn't an option, these are the documented numbers that matter.

1. Hermitlux HMX-DW03 Countertop Dishwasher — Best overall
Editor's choice Check price on Amazon
Hermitlux HMX-DW03 Countertop Dishwasher
Footprint (mfr)42.8 × 42.5 cm
Water sourcetank + faucet
Tank (mfr)5 L
Place settings (mfr)4
Four place settings from a 5 L tank — the best documented capacity-per-fill among tank-fed models. At 50 dB and 900 W, it sits in the middle of the noise and power range. The manual documents everything including a 15 cm clearance figure, which none of the other tank-fed models publish. Tank or faucet hookup — you start portable and can go permanent later.
Strengths (per specs & cited reviews)
- Most place settings among tank-fed models (4, per manual)
- Complete manufacturer documentation — zero unverified fields
- 15 cm clearance figure actually in the manual
Watch out for
- 42.8 cm wide — larger than the Bob
- Product page disagrees with manual on wattage (950 vs 900 W)
2. Daan Tech Bob the Mini Dishwasher (2 place settings) — Quietest
Editor's choice Check price on Amazon
Daan Tech Bob the Mini Dishwasher (2 place settings)
Footprint (mfr)34.0 × 49.0 cm
Water sourcetank + faucet
Tank (mfr)3.9 L
Place settings (mfr)2
At 43 dB documented, Bob is in a different noise class — apartment-friendly in a way no other model here can claim. The 3.9 L tank is smaller, and 2 place settings means solo or couple use only. But if noise is the constraint (open-plan apartment, night use, sleeping baby), nothing else comes close. Water use: 3.8 L per Eco cycle, the lowest documented figure.
Strengths (per specs & cited reviews)
- 43 dB — 7+ dB quieter than any competitor
- Smallest footprint (34 × 49 cm) and lowest water use (3.8 L)
- Dual-mode: tank for portability, water-line for permanent setup
Watch out for
- 2 place settings (manual's EN 50242 rating) — strictly for 1–2 people
- Smaller 3.9 L tank — one load per fill
3. Farberware Professional FDW05ASBWHA 5L Countertop Dishwasher — Best for RVs
Farberware Professional FDW05ASBWHA 5L Countertop Dishwasher
Footprint (mfr)43.9 × 41.9 cm
Water sourcetank + faucet
Tank (mfr)5 L
Place settings (mfr)2
The lowest wattage among tank-fed models: 750 W draws just 6.3 A at 120 V, which matters on RV circuits and older wiring. Water use is the lowest among the 5 L tank class (4.9 L/cycle). The manual confirms 2 place settings — Walmart's claim of 6 is flatly wrong. No official noise figure exists from Farberware.
Strengths (per specs & cited reviews)
- Lowest wattage here (750 W / 6.3 A) — most circuit-friendly
- Lowest water/cycle among 5L tanks (4.9 L documented)
- Tank + faucet dual-mode
Watch out for
- No official noise figure published
- Appears discontinued at first-party channels
4. HAVA R01 Compact Countertop Dishwasher
HAVA R01 Compact Countertop Dishwasher
Footprint (mfr)42.5 × 42.8 cm
Water sourcetank + faucet
Tank (mfr)5 L
Place settings (mfr)2
A well-documented 5 L tank model with dimensions nearly identical to the Hermitlux and ecozy (shared OEM platform). The manual covers all key specs on one page, which is more than most brands manage. At 60 dB documented noise, it's on the louder end — not ideal for open-plan spaces. Place settings: 2, per the manual's explicit 'maximum 2' statement.
Strengths (per specs & cited reviews)
- Complete single-page spec documentation in the manual
- Tank + faucet flexibility at 950 W
- 5 L/cycle water use documented
Watch out for
- 60 dB documented — among the louder tank-fed models
- Only 2 place settings per manual
5. COMFEE' CDC17P0AWW 5L Portable Mini Dishwasher
COMFEE' CDC17P0AWW 5L Portable Mini Dishwasher
Footprint (mfr)42.0 × 43.5 cm
Water sourcetank + faucet
Tank (mfr)5 L
Place settings (mfr)2
The COMFEE' CDC17 (the mini, not the full-size CDC22) runs on a 5 L tank or faucet hookup. Backed by Midea — the world's largest appliance maker — which means parts and support won't vanish. Key limitation: 62 dB documented noise makes it the loudest model here, and the manual never states a rated wattage (the '1200 W' online is just the circuit requirement).
Strengths (per specs & cited reviews)
- Major brand (Midea/COMFEE') — long-term support confidence
- 5 L tank + faucet dual-mode
- 2 place settings with 5 L/cycle documented
Watch out for
- Loudest documented noise (62 dB)
- Wattage unverifiable from official documents
6. ecozy DW-CT200A Portable Countertop Dishwasher
ecozy DW-CT200A Portable Countertop Dishwasher
Footprint (mfr)42.8 × 42.5 cm
Water sourcetank + faucet
Tank (mfr)5 L
Place settings (mfr)—
Near-identical dimensions to the Hermitlux and HAVA (likely the same OEM body), with a 5 L tank at 950 W. The problem is documentation: ecozy publishes no official figure for noise, place settings, or water per cycle. Retailers claim 48 dB and 4 place settings, but neither has manufacturer backing. If you value verified specs, the Hermitlux — same form factor, fully documented — is the safer pick.
Strengths (per specs & cited reviews)
- Tank + faucet at a competitive price
- Same proven OEM platform as Hermitlux/HAVA
- 950 W — standard for the class
Watch out for
- No official noise, place settings, or water/cycle specs
- Manual weight misprint undermines documentation confidence
Where our data comes from
We don't test dishwashers. Every specification below comes from the manufacturer's own documentation — user manuals, official spec sheets, and product pages — and links to its source. Where a retailer listing disagreed with the manual, we used the manual and flagged the conflict in our database notes.
If we couldn't verify a spec from an official document, it's shown as "—". We never estimate or use retailer-sourced figures.

Frequently asked
How do you fill a tank-fed dishwasher?
You pour water directly into the built-in tank — usually 5 L (about 1.3 gallons), which takes about 10 seconds with a large measuring jug. Most models have a marked fill line. The Bob by Daan Tech has a smaller 3.9 L tank. All six models here also accept a faucet adapter for permanent hookup.
How many loads can you run on one tank?
One. These machines use 3.8–5.0 L per cycle, which is close to the full tank capacity. You refill between loads. The upside: 5 L per cycle is a fraction of what hand-washing uses.
Can I use a tank-fed dishwasher in an RV?
Yes — that's one of the main use cases. The key constraints are wattage (750–950 W for these models, drawing 6.3–7.9 A at 120 V) and counter space. The Farberware at 750 W is the gentlest on circuits. Our RV Amp Calculator can check your total load.
Where does the dirty water go?
Every model has a drain hose that you run to your sink, a bucket, or (in an RV) an accessible drain. The drain is gravity-assisted on most models — no pump pressure that would reach a distant drain.
