VonHaus Submersible Water Pump Review: Efficient Hot Tub & Drainage Workhorse

When I moved into a house with a hot tub, one key task loomed: efficiently draining it for cleaning and winterising.

I chose the VonHaus Submersible Water Pump 400 W (with 8 m hose) for precisely that purpose, and it has proven to be impressively effective for the job. For such a relatively inexpensive pump, its performance, hose quality, and reliability have exceeded my expectations. Unlike some other models in the similar, relatively cheap price bracket, the VonHaus pump comes with a hose saving the additional purchase.

My summary: A powerful, budget-friendly submersible water pump that handles hot tub drainage tasks with ease, while offering good build quality and practical features. If you’re looking to drain a spa, pond, or flooded area without fuss, this is a solid choice.

Why I Bought the VonHaus 400 W pump

In my case the need was specific: draining a hot tub during cleaning or preparing it for winter storage. I didn’t want to manually empty the tub or rely purely on gravity drainage. The VonHaus 400 W pump promised a high flow rate (up to 7,500 L/h) and sufficient hose reach to drain the tub outdoors.

I had some concerns initially—particularly whether the supplied hose would be robust enough and whether the pump would cope with the volume—but so far it has delivered. The only learning-curve was ensuring hose connections were tightly secured with high clamp positioning (more on that below).

VonHaus Submersible Water Pump Hose Clamp — You need to make make sure the hose clamp is very tight to avoid leakages.

Product Overview & Specifications

Here are the key specs for the VonHaus pump:

Power: 400 W motorised pump.
Maximum drainage rate: up to 7,500 L/h (approx) in ideal conditions.
Hose length supplied: 8 m.
Power cable length: 10 m (mechanically sealed).
Maximum water depth (immersion) up to approx. 7 m; delivery head (vertical lift) up to 5 m.
Float-switch and thermal cut-out mechanism included.
Particle intake size: up to 35 mm wide solids.
Intended use: draining hot tubs, pools, ponds, flooded rooms, etc.

So in short: a 400 W submersible pump with a long hose, good flow rate and extra features like float switch for automatic shut-off.

Unboxing & First Impressions

When the pump arrived, it came securely packed with the main pump unit, the 8 m hose (pre-attached or supplied separately depending on packaging), a couple of jubilee clips (hose-clamps), an outlet hose connector, and the manual.

My immediate impressions:

The hose was thicker than I expected given the price, giving me greater confidence in long-term durability.
The pump body is somewhat weighty (around 5 kg), which makes sense given the motor and build.
The float switch cable length seemed generous, making it easier to place in the tub without constantly monitoring.
Assembly: simply attach hose to outlet, secure with clips, place pump in water, plug in. Straightforward.

One slight caution: I did notice that the first time I used the pump, there was a minor leak at the hose connection until I repositioned the jubilee clips higher up the hose. After doing that, the seal was rock solid and no further leak issues occurred.

Hands-On Use: Draining a Hot Tub

Here’s how the VonHaus pump performed in real-life use (my scenario: draining my 1500L hot tub for winter preparation).

VonHaus Submersible Water Pump in my hottub

Setup:

Turned off the hot tub heater and jets, removed debris from surface.
Positioned the pump fully immersed at the lowest point of the tub so it could remove as much water as possible.
Attached the 8 m hose, threaded it towards the garden drain. Secured connection tightly with jubilee clips.
Switched on the pump. The float-switch and thermal mechanisms were not in wide use (since the bucket remained full for the duration) but were reassuring to see.
Watched as the tub drained: the 7,500 L/h flow meant the tub went from full to nearly empty in around 45 minutes (to drain the remaining water, you need to use a dry/wet shop vac, read my review here).

Performance observations:

Flow was mostly excellent. The water discharge was fast, and the large hose kept up without any obstruction.
The hose quality held up well: no major kinks, no splitting, and the outlet connector maintained the seal.
As noted, the only issue was initially the hose connection; once corrected there was no dribbling.
The pump remained stable, didn’t overheat, and the cables were long enough that I didn’t worry about outdoor socket proximity.
For winterising, this level of drainage means less standing water in pipes or liner, reducing risk of freeze damage.

Overall impression: The VonHaus pump made what might have been a laborious manual job very straightforward. It’s quiet enough for garden use, the hose is adequate and of better quality than I anticipated, and the draining speed gave a sense of “job done”.

Review Summary

What works well:

Excellent value for money: you’re getting a 400 W drainage pump with long hose and accessories at a reasonable price.
It performs beyond expectations given its cost, especially for tasks like hot tub drainage.
Hose quality is better than expected — more rugged, less prone to splitting or kinks.
The extra features (float switch, thermal cut-out) add safety and convenience.
Easy to use: simple setup, plug-and-play.

VonHaus Submersible Water Pump is robust and ideal for emptying hottubs

What could be better / things to watch:

The hose connection must be secured properly — if the jubilee clips are too low or loosely fitted the hose may leak. My advice: position the clip high up and ensure tight seal.
While the 400 W motor is strong for many tasks, if you have deeper pools or very long hose runs you may find slower drainage or reduced head height. Know your setup.
As with all submersible pumps, you still need to manage hose routing and outlet placement; poor outlet or kinks will reduce performance.
If your hose is subject to sharp bends, you may want to buy an extra-thick or reinforced outlet hose for longer-term durability (though the supplied hose did hold up for me).

How the VonHaus stacks up (summary)

Compared to cheaper 330 W models (e.g., Einhell): VonHaus delivers noticeably more drainage capacity and usually includes a stronger accessory bundle (8 m hose, jubilee clips, long cable), making it faster and more versatile for hot tub tasks.
Compared to premium or higher-wattage models (e.g., Kärcher, FOTING, VEATON): VonHaus hits a sweet spot — enough power for most domestic hot tub and pond jobs without the extra cost, weight and power draw of industrial models. You don’t usually need 750 W for routine hot tub draining.
Value note: the VonHaus accessory bundle (hose, clips, float switch, long cable) is a strong practical advantage if you want an out-of-the-box solution for hot tubs and garden drainage.

So, for hot tub drainage and seasonal winterising, the VonHaus model hits a sweet-spot: strong enough for the job, well-specified, and cost-effective.

Pros & Cons

Pros	Cons
Strong drainage performance for its price.	Hose connection must be carefully secured (clamp positioning), otherwise risk of leak.
Hose quality is solid and gives confidence.	Depth/vertical head limitations: may struggle with very deep pools or long vertical lifts compared to heavy-duty pumps.
Long hose + long cable gives flexibility in placement.	Somewhat bulky for storage (approx. 5 kg).
Built-in safety features (float switch, thermal cut-out).	If used frequently for very large volumes, a higher-power model may be preferable.
Straightforward setup and use.
Excellent value for hot tub, pond or flood tasks.

Usage Tips & Best Practice

Always inspect the hose for kinks or damage before use. A kinked hose reduces flow dramatically.
Position the pump at the lowest practical point of your hot tub or pool to get most of the drainage.
Route the outlet hose so the water flows freely to drain — avoid uphill runs if possible.
Secure the hose with jubilee clips tightly at the pump outlet. My own experience: placing the clip just above the outlet lip prevented leaks.
Monitor the float switch (if used) to ensure the pump doesn’t run dry – unplug once water level is minimal.
Clean the pump after use (especially if draining dirty water) and store dry to prolong life.
If using outdoors in cold weather, store in frost-free location when not in use.
Ensure your power supply is safe and appropriately protected (RCD/earth) for outdoor use.
Use this pump for hot tubs, ponds, flooded areas, garden maintenance, but not as a permanent continuous duty industrial pump unless certified for such use.
