Capacity
The maximum amount of dry laundry at which the washing machine provides normal washing quality and does not experience overload. For two people, a machine with a capacity of up to
5 kg is enough, for more — accordingly, more. The optimal value for families are
models for 6 and
7 kg. For large families,
washing machines for 8 kg,
9 kg and even
10+ kg will be appropriate. For small apartments, it is worth noting
narrow washing machines that have a depth of up to 40 cm, but at the same time capacity like in full-size machines.
Note that for different work programmes the allowable capacity can also be different. For example, for a quick wash, this number is most often noticeably less than the maximum stated in the specifications. These details should be specified in the instructions for the unit.
Max. spin speed
Maximum drum rotation speed in spin mode. The higher it is, the more intense the spin. However, note that not all types of fabric normally tolerate high speeds — a speed
of 1000 rpm or more should be used only for especially durable fabrics, and delicate ones need to be wrung out at low speeds, so the best choice is a machine that allows you to choose the spin speed.
The maximum spin speed (
1200 rpm,
1400 rpm), in particular, determines its efficiency (see Spin class), but this parameter is not decisive — the duration of the spin cycle and the diameter of the drum also play an important role. Therefore, for machines with the same spin speed, their efficiency class may differ.
Steam wash
A special washing mode. Instead of water, hot steam is supplied to the drum of the machine. Steam penetrates better between the fibres of the fabric, which makes washing more effective than washing with hot water. At the same time, due to the high temperature of the steam — above 100 degrees — the best antibacterial effect is achieved since water in the liquid state rarely heats up above 95 degrees in washing machines. In addition,
steam wash saves water and electricity, but such machines themselves are quite expensive.
Leak protection
An automatic safety system that controls the integrity of the system for supplying and draining water to the washing machine and stops the water supply in the event of a leak. The protection can be installed on the hoses, on the body, or both (full protection).
Leak-proof hoses are equipped with special sensors and solenoid valves at both ends that shut off the water supply in the event of a breach in the hose. They can be used for both sampling and draining water. It is worth noting that for most washing machines, leak-proof hoses can be purchased separately, even if they are not included in the original package.
Protection of the body of the washing machine is carried out using sensors installed on the bottom of the device isolated from water. When water enters the bottom, its supply to the machine is turned off. The presence of leak protection allows you to avoid troubles like a short circuit or a flood in the house. However,
leak-proof machines are more expensive than conventional machines, all other things being equal.
