Inventor Power 50L 50L/day, with Water Pump Portable Dehumidifier & Smart Dehumidification for Lower Consumption & 2Year Warranty

I have a new build house with a cold damp detached garage and I have put the unit in there! I had to try something! I don't think it is the ideal working conditions for it, but it collected a third of a bucket of water in just a few hours! Bearing in mind it is probably not much over 5 degrees C in there it is very impressive. Only used for 1 day so far, but very impressed!

Excellent Customer Service. A flurry of support emails out of hours sorting out a problem. I am impressed. It has many useful features and most importantly seems to be making a damp area much drier.

Excellent machine. My one was used for one month continuously to dry out a damp cottage that had been freshly replastered so the water pump facility was essential. My only quibble is that the pump could do with a bit more capacity.

Great product. Very poor instructions.

SUMMARIZED REVIEWDoes its basic job well, but several aspects of the machine are poorly designed. Despite giving the machine only three stars I can recommend it for drying laundry in a poky home.DETAILED REVIEWThis review was written after the machine had been in daily use for over eight months, including three winter months. To ensure that the machine doesn't ice-up it is connected to a time switch that disconnects the power for at least two hours every twelve hours.Good points:(*) It performs its primary task of dehumidifying very effectively.(*) The fan that drives the air through the machine blows the exiting air horizontally from one side, which makes the machine particularly useful for quickly drying clothes on a wire frame. The fan is moderately large and hence provides a good airflow without being whiny.(*) The airflow is useful for simply circulating air within a room, and this circulating air will transfer dampness into the machine more efficiently than would happen in calmer air.(*) It isn't unreasonably noisy. The worst noise comes not from the machine itself but from other things in the room that vibrate in harmony with the machine; this can be avoided by putting the machine onto a solid surface or a vibration-absorbing surface, such as a springy-rug.(*) The four caster wheels revolve very smoothly and the manufacturer has very sensibly used four swivel casters whereas oftentimes manufacturers fit only two swivel wheels and two cheaper, non-swivel ones. Having all four casters swivel means that it is possible spin the machine around easily within its own footprint, and this is a very good feature because the machine can be positioned to direct the airflow somewhere particular, but then easily moved to allow access to the condensate collection tank. It also means the machine is very easy to tuck away into a tight space when it isn't needed.(*) The collection tank is larger than that on many other machines. This is important if you have a very damp room and need to leave the machine running while you are out for the day; a machine with a smaller tank might switch-off part-way through the day, whereas a machine with a larger tank can keep going that bit longer.(*) Dehumidifiers only work well above a certain ambient temperature. This machine uses more energy than a less powerful machine, and that energy ends up as warmth in the room. Consequently in winter, this machine manages to keep working in an otherwise unheated room whereas my 'other brand' dehumidifier that uses less electricity and therefore warms the room very little, gets too cold to operate at all.Bad points:(*) The water collection tank is nigh impossible to clean once it starts collecting mould and algae, which it eventually will given the nature of the machine. I consider this to be a serious design flaw, and deduct one and a half stars for this alone. The difficulty arises because of the way the tank is constructed with lots of rigidity struts in the bottom surface and across the upper opening and these make it difficult to insert anything (such as a hand or brush) into the tank, and make it impossible to scrub the bottom, or the dozens of corners. The only way I've found of cleaning the tank is to jet-wash it, and that's a messy job that can really only be done outdoors. Slimy algae, in particular, is very difficult to remove. By contrast the tank of my 'other brand' dehumidifier is trivially easy to clean. Note, if you are only using the machine intermittently and can afford to let the tank dry completely between uses then it is less likely that mould and algae will get established, and this 'bad point' will be less significant for you.Less than ideal points:(*) When the collection tank is removed all of the controls -- including the on-off-control -- become unresponsive until it is re-inserted. It is a minor inconvenience, but a completely unnecessary one.(*) The hysteresis is pathetic. The machine switches-off when it thinks it has reached the target humidity, stays off for a few seconds and then switches itself back on again although there is no possibility of the humidity having altered significantly in those few seconds.(*) The pump operation is feeble. Once the machine decides that the condensate collection tank is full it will pump at a rate of about 90 ml per minute for about 10 minutes; this rate assumes that discharge height is not more than a couple of feet above the machine and will presumably reduce slightly if there is a greater head of water in the tube. The pump is switched on by the level-sensor and is switched off by an internal timer. Ten minutes of discharge at 90 ml per minute means that it doesn't even discharge a full litre of condensate from the tank. This becomes an issue because the rest of the water is effectively sitting stagnating (and gathering mould and algae) and so the tank must be emptied manually periodically and cleaned -- but see the comments above about the near-impossibility of cleaning the collection tank.(*) The collection tank is a bit hard to re-insert due to the need to push the mechanism that lowers the drainage pump inlet back into the tank. It hasn't broken from the exertion yet, but it does feel more fragile than I'd like.Things I just don't like:(*) The control buttons are the cheap and nasty membrane type that wears out and breaks faster than any other type of electrical button ever invented. Fortunately most people probably won't want to use the buttons often so the wear on them will be slow and in that case they'll survive for years.If you needed to use the machine unattended in a basement you might find the built-in pump inadequate and in that case you'd need to have the machine drain into some other tank, and then use a decent sump-pump to empty that second tank periodically. Of course you could employ the same technique with any other dehumidifier.Overall the machine performs its basic task well and the good points of the machine are such that I do recommend it for your consideration, especially if you need to dry laundry in a poky flat. The weak points are many, but some will be irrelevant in some situations: For example if you use direct-drain or can empty the condensate collection bucket easily then you won't care about the feeble pump, and if you can let the machine dry out completely for a few days occasionally then the mould and algae problem won't 'grow' as it does for me. I would at least consider buying another of these machines should I ever need another dehumidifier.

Great product that is well designed, would have no problem recommending. Have been using in a 100m2 living space for last few months where we had an un-noticed leak from our patio doors/roof. Keep the space at 30. We have a floating insulated slab which has under floor heating. The leak went underneath the insulated slab and is now giving us rising damp on the outside walls where the moisture is condensing. As the whole room is chemically tanked the only way to pull out the moisture is through the slow process of it condensing up the walls and then evaporating into the room. Pulls out 6 litres a day from our main living space which has kitchen and laundry. Additionally I use it in our small laundry room to dry clothes, brilliant with large towels (usually dry in 2 hours). When using in the laundry it pulls huge amounts of moisture out of the washing in a very short period, much quicker than the condensing tumble dryer and far cheaper too.I was loaned two smaller machines, this is quieter and is far more efficient, taking account of their ratings. The condensing plate on the smaller machines would click on and off.When living with such a machine in your living space you generally get used to the fan noise, but we do switch it off for watching the TV in the evenings and while we are having food if the machine is close.The only thing that is a little strange initially is that on starting/restarting the machine it can take a minute/few minutes to start up. Once you are used to this it's fine, but initially I thought that there was something wrong. Perhaps a flashing light or a code would be reassuring to indicate it's initialising / in start up mode.
