The Gtech Pro is Gtech’s first bagged vacuum cleaner with cordless design. It comes with four attachments, the Power floor head, Power brush, Dusting brush and Crevice tool, as well as 2 replacement bags. The bag helps to keep hygienic and dust free when maintaining your vacuum but will incur additional cost to replace them (£9.99 for a pack of 10), with the average household using between 4-8 bags a year. The bag will typically hold 1.5lt, which means you should be emptying it less than the bag free counterparts.
