The X4 is the machine that sells the brand: automatic height adjustment means the head sets itself for carpet and hard floor without a dial, a 40 foot cord covers a big room without changing outlets and three full-size tools ride on the body. The maker backs it with a 7-year motor warranty and a lifetime belt warranty, which is the strongest durability statement in this guide.
A low profile of about 5.5 inches reaches under furniture. Compared with the Essential G5 it adds automatic height and the longer warranty, while the G5 adds a few convenience features. The Dart offers a powered head for pets.
Upkeep is simple and cheap. Change the filter bag when it is about two thirds full, check the belt access cover, and keep a spare belt and filters with the machine. Because the belt is warrantied, you can swap it yourself in a couple of minutes, and the sealed filtration path means the bag does most of the work of keeping dust out of the air. Treat the cord with the respect a long cord deserves: wind it in loose loops on the hooks, check the strain relief at the body once a year and never let the head run over it, because a 40 foot cord is the most expensive part to replace and the most common casualty in a house where the vacuum is used daily. The 5.5 inch profile is only an advantage if you tilt the handle low when you go under a bed, so make a habit of that rather than pushing the head in at an angle that scrapes the frame.
