Renters without access to a water supply
A model with a water tank means you don’t need a fixed water connection, as long as you can fill it and direct the waste water to a drain after every cycle.
Who might these appliances suit?
Small households with larger dishes
If there are one or two of you, the advertised place settings aren’t the only thing to consider. Plate diameter and the space taken up by bowls or a small saucepan matter too.
Kitchens with limited worktop space
You’ll need a stable spot where the door can open, the appliance can be filled and the drain hose can reach, while keeping a suitable socket within easy reach.
What should you check before choosing?
Start by checking the water supply and drainage, then measure your dishes and the available space. Before ordering, check the instructions for your chosen model to confirm its electrical requirements too.
Water-tank model
Consider this if: you can’t leave a tap supplying water to the appliance during a cycle.
Be prepared to: fill it by hand and drain the waste water after every use.
Temporary tap connection
Consider this if: the tap is accessible and can remain free while the dishwasher runs.
Be prepared to: check that the connector is compatible and keep the tap in use for the duration of the cycle.
Washing up by hand
Stick with this if: your dishes are often too large for a small dishwasher, or there’s no safe way to drain the water.
Be prepared to: keep washing up by hand, although accessories can help you organise the space.
| What to consider | What to check | Who is this for? |
|---|---|---|
| Water supply and drainage | Find a suitable place to drain the waste water and measure the hose route. If the model connects to a tap, check the connector too. | Without a fixed water supply, I want to be able to start a cycle without permanent installation, while knowing where the waste water will go. Around 29% of consumers prioritise this ease of installation and drainage. |
| Usable capacity | Measure your largest plate and compare your usual load with the dimensions and loading example provided by the manufacturer. | If I regularly wash bowls and a saucepan alongside my plates, I want to know whether they’ll actually fit inside. This is a top priority for around 29% of consumers. |
| Space and stability | Measure the available space, allowing for the door to open and the hoses, then check that the surface can support the appliance when loaded. | In a small kitchen, I need to keep enough usable worktop space without balancing the appliance precariously. Around 24% of consumers put size and stability at the top of their list. |
| Everyday use | Consider how the appliance is filled and maintained, as well as its programmes and energy and water use under comparable conditions. | I want to spend less time washing up by hand without replacing it with lots of extra steps after every meal. Ease of use is a priority for around 18% of consumers. |
What mistakes should you avoid?
-
Assuming ‘no fixed connection’ means ‘no need to manage the water’
A water tank means you don’t need a permanent water supply, but you’ll still need to fill and drain the appliance. Daan Tech, for example, specifies a 1,50 m drain hose for Bob. Make sure it’s long enough to reach your sink or container from the appliance’s actual position.
Measure the hose route and try out the position with the door open before you choose.
-
Relying on the number of place settings alone
An oversized plate or bulky saucepan could stop you loading everything you planned, even if the advertised number of place settings sounds sufficient.
Measure the dishes you use regularly and compare them with the stated maximum plate diameter and loading examples for the exact model.
-
Comparing different cycles as if they were the same
A quick cycle and an Eco programme don’t necessarily offer the same kind of wash. Differences in water use, energy use or cycle time aren’t enough on their own to decide between two appliances.
To compare consumption, check the programme, load and measurement conditions behind each figure.

Treating customer reviews as a reliability test
A review may relate to a different variant, length of use or customer service experience from your own. Trustpilot says it doesn’t verify individual claims published in reviews.
Read recent reviews and check which model they relate to, then look separately at the warranty terms, spare parts and consumables.

Frequently asked questions
Can a water-tank model work without any drainage?
No. Not needing a fixed water supply doesn’t remove the need for drainage. Daan Tech says Bob has a hose that should be directed into a sink or another drainage point. For the model you choose, check where the waste water will go throughout the entire cycle.
How can I check whether my plates will fit inside?
Measure your largest plate and compare it with the maximum diameter accepted by the exact model. Daan Tech lists a maximum of 29 cm for Bob, while HAVA specifies up to 26 cm for the R09 and Klarstein up to 26 cm for the Oceana. Check separately that there’s room for bowls and saucepans.
What should I check about the electrical connection?
Check the instructions for the variant on sale for its voltage, power rating and connection requirements, then make sure your socket is in good condition and suitably located. Information about Bob doesn’t tell you what another model requires.
Are customer reviews enough to tell whether a model will suit me?
No. Reviews can flag things to look into, but they don’t replace measuring your kitchen or checking your dishes. Check which variant and usage conditions each review describes. Trustpilot says individual claims published on its platform aren’t verified.
