The Best Dehumidifier with a Drain Hose (or a Pump)

If you're tired of emptying a bucket, here's how continuous drainage really works — and the one question that decides whether a hose is enough.

Why this is the decision that matters most
Most people shop dehumidifiers on pints. Then they own one, and discover the thing they actually interact with every single day is the bucket.
We divided every unit's tank size by its rated daily output to find how often you'd really empty it. The spread is nearly eightfold — from over a full day, down to under four hours. A 50-pint unit in a damp basement will fill its tank twice a day. Nobody keeps that up for a season.
So for anything larger than a bedroom, continuous drainage isn't a feature. It's the point.
Gravity hose vs built-in pump
There are two kinds of continuous drainage, and confusing them is the classic mistake.
A gravity hose runs downhill from the unit to a floor drain or a lower sink. Simple, reliable, silent, nothing to break — but it only works if the drain sits below the outlet, with a continuous downhill run and no dips along the way.
A built-in pump actively pushes water up and out. It can reach a sink, a window, or a standpipe above the unit. If your drain isn't conveniently below the machine — which describes an awful lot of basements — this is the only thing that solves it.
Who has what
| Dehumidifier | Gravity hose | Built-in pump | Hose in the box? |
|---|---|---|---|
| Midea Cube 50 | Yes | Yes — 16-ft lift | Yes |
| Frigidaire FHDD5034 | Yes | No | No |
| Midea Cube 35 | Yes | No | Yes |
| Waykar 34 | Yes | No | Yes |
| Ivation IVADDH06 | Yes | No | Yes |
| Pro Breeze mini | No | No | — |
Best with a pump: Midea Cube 50
The Midea Cube 50 with pump is the only unit here with a genuine built-in pump, and it lifts water up to sixteen feet through the included tube. For a basement with no low drain, it's the one that makes hands-off drainage actually possible. It's also the quietest 50-pint we found, so it's not a compromise pick.
Best with a gravity hose: Frigidaire FHDD5034
If you do have a low drain, don't pay for a pump. The Frigidaire FHDD5034 has a threaded outlet, 49.7 certified pints a day, and the best capacity per dollar in the category — $29 less than the Cube. We settle whether the pump is worth the difference.
One genuine annoyance, and it's worth knowing before you buy: Frigidaire doesn't include the hose. It's a standard garden-hose thread, so any hose works, but you'll want to have one ready on day one.
The catch with gravity hoses
They only work with a continuous downhill run. No dips, no climbs, no coiling the excess on the floor — water sits in the low spot, the line backs up, and the unit switches to filling its bucket again without telling you. If the run is long, or has to climb even slightly, that's a pump job.
And if you're using a mini: the Pro Breeze has no continuous drain at all. Minis are hand-emptied, full stop.

Bottom line
Ask one question: can a hose run downhill from the unit to a drain? If yes, buy the Frigidaire, add a hose, and never think about it again. If no, buy the Cube 50 — the pump is the whole reason it exists. The quiz asks how you want to drain it and gates accordingly.
Frequently asked
Do all dehumidifiers have a drain hose option?
Most full-size units have a threaded outlet for a gravity hose, though not all include the hose — the Frigidaire notably doesn't. Thermo-electric minis usually offer no continuous drainage at all and must be emptied by hand.
What's the difference between a drain hose and a pump?
A gravity hose only drains downhill, so the drain must sit below the unit. A built-in pump actively lifts water up to a higher sink or out of a window. Choose the pump if you can't drain downhill — that's the entire decision.
Can I leave a dehumidifier draining continuously?
Yes — that's the point. With a hose or pump connected and the humidistat set to a target, it runs hands-off and never fills a bucket. This is essential for anything bigger than a bedroom.
Why did my drain hose stop working?
Almost always a dip or a coil in the run. Gravity hoses need a continuous downhill slope; water pools in any low spot, the line backs up, and the unit quietly switches back to filling its tank. Re-route the hose so it falls the whole way.
