Thank you for your feedback. We only have a very limited space to describe our products in the brochure, which is why on every page we suggest you call our Sales Team for advice - we're always happy to advise the products best suited to your needs as with pond equipment it's never 'one size fits all'. We do have more information on our products available on our web page, and there are various videos available showing the vacuum in action online. Sorry it wasn't suitable for your pond set up, we do stock a range of vacuums and there is something for everyone. If you require any further help or advice please get in touch.
