A dehumidifier pulls damp out of the air, but the part almost nobody thinks about until it's too late is where all that collected water actually goes. The cheap ones make you carry a sloshing tank to the sink two or three times a day, and in a basement that is exactly the chore you will start skipping. We analyzed thousands of verified buyer reviews, recent sales data, and expert evaluations to find six dehumidifiers whose built-in pump moves the water for you and keeps the unit running on its own.
Short on time? These three cover most buyers: our top-graded overall pick, the best choice for a large basement with no floor drain nearby, and the best value among this lineup's genuine pump-equipped units.
34 pints/day · 2,500 sq ft rating · gravity drain only
Our Best Overall pick by buyer and expert score - though worth flagging immediately: this specific listing has no built-in pump and drains by gravity hose or removable tank only.
Gasbye DryPrime 75-Pint Dehumidifier with Replaceable Pump (4,500 Sq. Ft.)
4.9
75 pints/day · 4,500 sq ft rating · replaceable pump
A genuinely different take on the pump problem, with the pump sitting inside the tank for easy cleaning and a standalone replacement pump so a failure doesn't mean scrapping the whole unit.

Waykar 125-Pint Crawl Space Dehumidifier with Pump (6,500 Sq. Ft.)
4.7
125 pints/day (max) · 6,500 sq ft rating · 16.4 ft pump lift
The largest-capacity machine in this lineup: a commercial-grade unit built for extreme, hard-to-reach damp spaces, with both a pump and a gravity hose included and a 5-year compressor warranty.
Dehumidifiers with Pump 101: What They Do & How to Choose
Understand the category before you buy - what the science actually says, and which specs matter.
Every model here promises to dry out a room, but the pump is the feature that changes how you live with it, and after that it comes down to matching capacity and coverage to your space. Here is how the pump works, why it matters more than the headline pint number, and the specs actually worth comparing.
What does a dehumidifier with a pump actually do?
A dehumidifier draws humid air across a cold coil, condenses the moisture into water, and collects it. A standard unit holds that water in a tank until you empty it or drains it by gravity through a hose. A pump model adds one thing on top of all that: a small pump that pushes the collected water out for you.
In plain terms it does three jobs:
Removes moisture from the air, rated here from 34 pints a day up to 125 pints a day at peak conditions.
Collects the water in a tank or routes it straight to a hose.
Actively pumps that water up and away so you never have to lift and dump it.
Why the built-in pump is the whole reason to buy this type
This is the part worth understanding before you compare anything else. A normal dehumidifier drains by gravity, which only works if you have a floor drain sitting lower than the unit. Water does not run uphill, so if your only drain is a utility sink, a window well, or a spot across the room, gravity drainage is useless and you are back to hauling the tank.
A built-in pump solves exactly that. Instead of relying on a downhill slope, it actively pushes the water UP and out through a hose, into a sink, out a window, or across the floor to wherever your drain actually is. The models here that spell out their reach, led by the 5,000 sq ft DECIUU, which lists a 16.4 ft lift, plus the Gasbye's replaceable pump reaching roughly 16 ft, are enough to clear a basement wall and reach a sink or standpipe on the level above.
That is the difference between a dehumidifier you empty by hand every few hours and one you set up once and forget. The lineup does include two gravity-drain options that ship without a pump at all, namely the AEOCKY 80-Pint and the VEAGASO 34-Pint, and they are fine if you happen to have a low floor drain right beside them. If you don't, the pump is the entire point.
Which specs actually matter?
Once the pump is settled, a handful of numbers decide which unit fits your space:
Pump vs gravity drain: Confirm the model has a real built-in pump, not just an included gravity hose. The 5,000 sq ft DECIUU unit pairs a pump with a gravity-hose or manual-tank backup so you can pick whichever method suits your space, while the Gasbye and AEOCKY LEO rely on their pump as the primary drainage method.
Pump lift height: This is how high the pump can push water. A 16.4 ft lift, as on the 5,000 sq ft DECIUU unit, clears most basement setups; the Gasbye's replaceable pump reaches close to that at roughly 16 ft. A shorter lift may not reach an upstairs sink.
Capacity in pints per day: The daily removal number, from 50 pints up to 100 pints (max) here, tells you how fast it dries a space. Match a bigger number to a damper room, not just a bigger one.
Coverage in square feet: Advertised coverage runs from 3,500 sq ft up to 7,500 sq ft. Size it to your room so the unit isn't straining or wildly oversized.
Built-in humidistat: A humidistat lets you set a target humidity and holds it, cycling off when the air is dry enough. The 40-80% adjustable range on the AEOCKY units here is a good example of the control that keeps a unit from running forever.
Tank size: Tanks here span 0.8 gallons up to 1.6 gallons. It matters less when you drain continuously, but a larger tank means fewer trips on the days you skip the hose.
Auto shutoff and restart: Auto shutoff stops the unit safely if a tank fills, and auto restart brings it back after a power blip so a tripped basement outlet doesn't leave you damp for a week.
How we grade products
Graded Picks rankings are aggregated from several independent signals: verified buyer ratings and the size of the review base for credibility, recent monthly purchase volume for relevance, assessments from trusted home and appliance publications, and how each product places in leading category lineups. For dehumidifiers with a pump we weigh:
Pump reliability and rated lift height
Daily moisture removal versus advertised coverage
Humidistat accuracy and control range
Continuous drainage setup and hose quality
Auto shutoff, restart, and defrost handling
Noise and everyday operation
Warranty and overall value
Setup and maintenance note: A pump only helps if the drain hose runs cleanly to its destination without kinks or dips that let water pool and freeze or clog. Route it to a sink, window, or drain before you rely on continuous mode, keep the intake filter clean so airflow stays strong, and in an unheated space watch that temperatures stay high enough for the coil to work, since very cold air holds little moisture and can ice the unit.
In-Depth Reviews
Everything we learned from buyer reviews and expert testing, product by product.
Our Best Overall pick by overall buyer and expert score, with one important caveat up front: this specific listing has no built-in pump. The VEAGASO 34-Pint covers a rated 2,500 sq ft with three operating modes (dehumidify, dry and continuous), an intelligent humidistat, and quiet sub-40 dB operation on its low setting that reviewers single out as suited to bedrooms and home offices. It's a straightforward, set-and-forget unit: automatic shutoff and restart, a digital display, and a continuous-drain hose that empties the tank without manual dumping. Like the AEOCKY gravity-drain listing elsewhere in this comparison, it has no built-in pump, so it only works installed above a floor drain and can't push water up to a sink or window the way the Gasbye, AEOCKY LEO and DECIUU pump models here can. Buyer sentiment is generally positive on quiet operation and ease of setup, though a portion of owners feel actual moisture removal falls short of the 34-pint rating in consistently high-humidity conditions - a common gap between rated and real-world capacity in this category. It also carries the lowest price of any model in this comparison, which is the main reason to consider it if a floor drain is already within reach; buyers who need the pump this category page is built around should look to the Gasbye, AEOCKY LEO or DECIUU picks instead.
Coverage area (advertised)2,500 sq ft
Daily removal capacity34 pints
Tank volume2 liters (0.53 gallons)
DrainageGravity drain hose or removable tank (no pump)
Dimensions (D x W x H)19" x 10" x 12.5"
Modes & controls3 modes (dehumidify, dry, continuous), digital display, timer

Pros
Top-graded pick in this comparison by overall buyer and expert score
Quiet sub-40 dB operation well suited to bedrooms and offices
Three operating modes plus automatic shutoff and restart
Continuous-drain hose avoids manual tank emptying above a floor drain
Lowest price of any model in this comparison
Cons
No built-in pump - despite being our top overall pick, it only works with a floor drain below the unit; buyers who need pump drainage should choose the Gasbye, AEOCKY LEO or DECIUU instead
A portion of owners feel real-world moisture removal trails the 34-pint rating in very humid conditions
Thinner tank volume than the pump-equipped units in this lineup
Who is it for?
Buyers who already have a floor drain nearby and want our top-graded overall pick at the lowest price in this comparison.
Who is it not for?
Anyone without a floor drain who specifically needs a pump - despite being our top overall pick, this listing can't push water upward; the Gasbye, AEOCKY LEO or DECIUU pump models in this comparison are built for that.
The single most common complaint about pump dehumidifiers is the pump wearing out before the rest of the machine does, and Gasbye's DryPrime addresses that directly by placing the pump inside the water tank, where it's easy to access and clean, and by selling a standalone replacement pump so a failed pump doesn't mean buying an entirely new dehumidifier. It's rated for 44 dB quiet operation, removes up to 75 pints per day across a 4,500 sq ft rating, and supports roughly 16 feet of vertical drainage through the included 16.5-foot hose. Four modes (normal, continuous, auto, sleep) plus auto shutoff and restart round out the feature set. As a newer brand, independent professional-review coverage beyond the manufacturer's own materials is still thin.
Coverage area (advertised)4,500 sq ft
Daily removal capacity75 pints
Tank volume1.45 gallons
DrainageReplaceable built-in pump (~16 ft lift), 16.5 ft hose included
Dimensions (D x W x H)10" x 15" x 24"
Modes & controls4 modes (normal, continuous, auto, sleep), auto shutoff/restart
Warranty2 years
Pros
Pump can be replaced on its own instead of requiring a whole new unit
Pump sits inside the tank for easy access and cleaning
Quiet 44 dB operation
Long 16.5 ft drain hose included
Four operating modes with auto shutoff and restart
Cons
Little independent professional-review coverage beyond the manufacturer's own site
Newer brand without a long track record
No discount at time of scan, pricier relative to similarly specced rivals
Who is it for?
Buyers who want insurance against the single most common pump-dehumidifier failure: being able to replace just the pump instead of the whole unit.
Who is it not for?
Shoppers who want a long-established brand with extensive independent testing behind it.
3. AEOCKY 80-Pint Energy Star Dehumidifier (4,500 Sq. Ft., Gravity Drain)
4.9
This AEOCKY carries an Energy Star Most Efficient 2025 certification, quiet operation in the mid-40s dB range, and five operating modes plus a child lock and timer, and it's broadly well regarded for real-world moisture removal. The important caveat for this comparison: it ships without a pump. The included hose relies entirely on gravity, so it only works if the unit sits above a floor drain - it cannot push water up to a sink or window the way the pump models on this page do. For a basement or room without a floor drain, the Gasbye or DECIUU pump models in this comparison are the direct upgrade path.
Energy Star Most Efficient 2025 certification for lower running costs
Quiet operation in the mid-40s dB range
Five operating modes plus child lock and timer
Extended supplemental warranty tiers available
Strong reputation for real-world moisture removal
Cons
No built-in pump - gravity drain hose only, needs a floor drain below the unit
1.45-gallon tank fills quickly without hose drainage
4,500 sq ft coverage claim is optimistic for a genuinely damp basement
Who is it for?
Buyers who already have a floor drain and want AEOCKY's efficiency and quiet operation without paying for a pump they won't use.
Who is it not for?
Anyone without a floor drain - despite appearing in this comparison, this model cannot pump water upward; the Gasbye or DECIUU pump models above are the ones to get instead.
4. AEOCKY LEO 80-Pint Dehumidifier with Pump (4,500 Sq. Ft.)
4.8
Our Best Value pick. AEOCKY's LEO pump model keeps the brand's 80-pint capacity and 4,500 sq ft rating, then adds an electromagnetic pump the brand has put through extensive reliability cycling, with a dual-sensor system designed to prevent the pump from running dry and aging prematurely. It actively pushes water upward for what AEOCKY calls true 360-degree auto-drainage, ending manual tank emptying, and the roughly 16-foot hose ships in the box. Operation stays in the mid-40s dB range typical of the brand's lineup, and it's app-connected for remote control. Among this comparison's genuine pump-equipped models - the Gasbye, the DECIUU and the Waykar - it's both the newest arrival and the least expensive, a trade its price reflects: a shorter independent track record in exchange for the lowest-cost way into pump drainage here.
Coverage area (advertised)4,500 sq ft
Daily removal capacity80 pints (max)
Tank volume1.45 gallons
DrainageBuilt-in pump, 360-degree auto-drainage, ~16 ft hose included
Dimensions (D x W x H)14.4" x 8.6" x 23.3"
Modes & controlsAutomatic mode, app-connected control
Warranty3 years (5-year compressor)
Pros
Lowest price among this comparison's genuine pump-equipped models - our Best Value pick
Genuine built-in pump with 360-degree auto-drainage - no floor drain needed
Quiet mid-40s dB operation typical of the AEOCKY line
Dual-sensor system guards against running the pump dry
App-connected remote control
Cons
Shorter independent track record than the category's most established brands
Smaller 1.45-gallon tank than some rivals
4,500 sq ft coverage claim is optimistic for a consistently damp space
Who is it for?
Buyers who need genuine upward pump drainage without paying the most for it.
Who is it not for?
Buyers who prioritize a long independent testing history over price - this AEOCKY LEO is a newer listing without that track record yet.
5. DECIUU 100-Pint Energy Star Dehumidifier with Pump (5,000 Sq. Ft.)
4.7
Our Best for Large Basements pick. Review roundups focused on pump dehumidifiers name the DECIUU specifically as the pick for large basement spaces, and the reason is its drainage flexibility: a built-in pump rated for a 16.4-foot vertical lift, plus gravity drain and manual tank as backups, so it can be installed even where competitors' shorter pump lifts or gravity-only hoses can't reach a drain. It carries Energy Star Most Efficient 2024 certification and covers a rated 5,000 sq ft, removing 70 pints per day at standard conditions with a 100-pint max figure at 95°F/90% RH. An intelligent humidity sensor holds the target level within a tight band and a memory chip preserves your settings through power outages. As a newer brand, it has a thinner independent professional-review footprint than the category's most established names.
Coverage area (advertised)5,000 sq ft
Daily removal capacity70 pints (100-pint max at 95°F/90% RH)
Tank volume1.45 gallons
DrainageBuilt-in pump (16.4 ft lift), gravity drain, or manual tank
Dimensions (D x W x H)8.65" x 14.38" x 24.09"
Modes & controls3 fan speeds, humidistat, auto defrost/restart
Warranty2 years (1 year standard + 1 with registration)
Pros
Energy Star Most Efficient 2024 certified
Ties for the longest pump lift in this lineup at 16.4 ft, for basements far from any drain
Three drainage options for maximum installation flexibility
Precision humidity sensor holds the target level
Retains settings through power outages via a memory chip
Cons
Thinner independent professional-review footprint than the category's most established brands
1.45-gallon tank is modest for a 100-pint-max machine
Newer brand without a multi-year track record
Who is it for?
Large or severely damp basements where the nearest drain is well above floor level and efficiency matters.
Who is it not for?
Buyers who want a long-established brand name behind a big-basement purchase.
6. Waykar 125-Pint Crawl Space Dehumidifier with Pump (6,500 Sq. Ft.)
4.7
The Waykar is the biggest and most industrial-oriented machine in this comparison, built for crawl spaces, construction sites and commercial areas rather than a finished living room. It's rated to pull up to 125 pints per day at 95°F/90% RH across a claimed 6,500 sq ft, backed by a 300 CFM blower and a wide 10-98% humidistat range that goes lower than most residential units. Drainage is continuous by design: a 16.4-foot pump hose handles vertical lift to a sink or window, and a 6.6-foot gravity hose covers straightforward downhill runs, so there's no standalone bucket to empty. Buyers report meaningful real-world results - one owner recorded crawl-space humidity dropping from 84% to 58% in about 12 hours - and Waykar backs the compressor for 5 years with a 30-day money-back guarantee and lifetime technical support. As a newer, specialty listing it carries less independent professional coverage than the category's established basement dehumidifiers.
Coverage area (advertised)6,500 sq ft
Daily removal capacity125 pints (max, at 95°F/90% RH)
Tank volumeNo standalone tank - built-in pump + continuous gravity drain only
DrainageBuilt-in pump (16.4 ft lift) + 6.6 ft gravity hose, both included
Dimensions (D x W x H)19.29" x 12.6" x 13.58"
Modes & controlsDigital display, humidistat (10-98% RH), timer, auto shutoff/restart, auto defrost
Warranty5 years (compressor); 1-year standard + 2-year extended coverage
Pros
Largest rated capacity in this lineup at 125 pints per day (max)
Both a 16.4 ft pump hose and a 6.6 ft gravity hose included for flexible installation
Unusually wide 10-98% humidistat range for extreme damp environments
5-year compressor warranty plus a 30-day money-back guarantee
Built with a corrosion-resistant metal casing for crawl spaces and job sites
Cons
Newer, specialty listing with less independent professional coverage than established basement dehumidifiers in this category
No standalone water tank - it depends entirely on the included hoses for drainage
Sized and priced for serious crawl-space/commercial jobs, overkill for an average bedroom or bathroom
Who is it for?
Owners tackling a genuinely extreme, hard-to-reach damp space - a crawl space, construction site or commercial area - who need the highest-capacity, hose-only machine in this comparison.
Who is it not for?
Anyone dehumidifying a normal bedroom, basement or bathroom - every other machine in this lineup is sized (and priced) more sensibly for that job.
