If your doing Commercial you need The titan, £3200 ish.... Domestic The electric(improved version) R2D2 At around £1900, Yes that's is right the tubes are much larger than the omnipole.Its all down to your preferences and above all, how much your prepared to pay. Get a demo from both and make up your own mind. They both have pros and cons. For me the set up on the upkeeper is much quicker than the omnipole, the power of the omnipole is greater than the R2D2 but not the titan. The different attachments you get with both upkeepers is fantastic, real solid and should cover most types of guttering. If you choose the omnipole you can do both domestic and commercial, as the R2D2 and the titan are two very different machines with two very different prices.
