Our verdict
If your garden's on the small side, a rotary washing line will likely take up too much room, leaving you unable to enjoy your lawn in the sunshine. The Vileda Cordomatic is one of Mumsnet users' best retractable washing lines, offering a clever solution to a lack of outdoor space.
Taking up practically zero space, the washing line is screwed to a sturdy post or wall. When your laundry is out of the washing machine, pull the line out from its plastic case and fix it to a hook on the opposite side of your garden. There's a simple hook to lock the line in place and keep it taut, then it's ready to hang out up to 15kg of wet washing using your best clothes pegs. Once your washing's dry, unhook and unlock the line and it'll wind itself neatly away for next time.
As a space-saver, it's very impressive. But when compared to a heated clothes airer or even the best tumble dryer, the fact that the retractable washing line uses zero energy is another point in its favour.
A word of warning - you will need a power drill to fix the Vileda Cordomatic safely and securely enough to support the weight of a load of washing. The washing line is a bargainous £11, but if you don't already have a drill, this is potentially an extra expense to consider. Mumsnetters recommend a combi drill like this Bosch Cordless Combi Drill for a good all-rounder.

How easy is the Vileda Cordomatic Retractable Washing Line to install?
The Vileda Cordomatic comes will all fittings included in the box. There are two screws, a hook and wall plugs. Drill pilot holes in your wall or post, push in the wall plugs then fix the washing line's metal bracket onto the wall using the screws. Tamsin fixed her washing line to the side of her garden office, so when the washing line isn't in use, you wouldn't know it was there.
If you're not very handy, don't be put off by the DIY involved. The process is simple and straightforward, and the metal bracket can be unscrewed from the main plastic case for installation, so you'll be able to see what you're doing and mark the holes with a pencil before you begin drilling.
Tamsin said she'd have preferred a washing line that didn't require DIY to install, which is a fair point. It doesn't look like there are any on the market currently, so if you want to avoid power tools a small rotary washing line like the Vileda 4 Arm Rotary Dryer might be a better bet.
