Installing Bosch WLX 16160 in holiday apartment

We have a small apartment in Greece. There’s insufficient space to have an automatic washing machine permanently located close to the available plumbing and it seems that twin-tub systems are just no-longer available, on the island of Rhodes anyway.

While we were in Greece last week we ordered a new Bosch WLX1610 which is a slimline (44cm deep) automatic washing machine (similar in size to the WLX24162 which is available for the UK market). We take delivery when we go back to the apartment in May.

The idea is to have cold water feed installed underneath the sink unit and, probably once a week, move the machine across the kitchen, plug it in and connect up the water allowing the water outlet to discharge into the sink.

There are two things we need to sort out to allow our plan to work:
I was intending buying a pair of appliance rollers (available from Betterware and other outlets) to wheel the machine into position and leave it on the (lockable) rollers while the washing is done – in fact just leave them on there all the time.

Secondly, I’m trying to find a sucker system which will hold the outlet hose against the side of the sink when it discharges – just like the old system used on twin-tubs.

Does anyone see any pitfalls in this plan and does anyone know where I can buy suitable suckers to hold the hose to the sink? I’m worried that just using a drain hose hook will not stop the hose flying off the side of the sink when the machine discharges. Or perhaps this worry is unfounded?

I want to keep things as simple as possible because dealing with Greek plumbers; well let’s just say it’s best avoided.

Thanks in advance.
