One of the few "high spec" tools my ship was supplied with was cordless dysons for the stewards. Batteries or motors all died in a year of daily use.
Now have a fleet of regular and handheld Henries. Absolutely zero problems
Crazy to me how Dysons cost £800, constantly need maintenance and often don't work very well, all whilst being built overseas by cheap labour. Meanwhile Henrys cost £110, never go wrong, are incredibly effective, yet are all built in Somerset. Makes you think!
