Karcher WD 5.200 MP
Money no object
This is the heaviest, tallest and most powerful vacuum tested, but there’s more to the WD 5.200 MP than just superlatives.
It has a sturdy handle and you can plug a power tool into the on-board socket. A switch lets you adjust the force and it easily sucked up the most dirt.
It’s simple to use and didn’t tip over when we pulled the hose. But unless you need a big 25-litre drum, the WD3.300 M is a better all-rounder.
