I noticed that Panasonic have gotten good recommendation from Which? for their MC-UL594 machine.
Mum got the next model up, the purple 596 for Christmas. I have tried it, and I'm actually rather impressed by it.
The brushroll has closely spaced clumps of short splayed bristles, so the carpet pile is effectively groomed. The brush vibrates the carpet very effectively, yet there are no beater bars. The pleated filter doesn't appear to be clogging; it has a manually operated flicker mechanism and a few taps on the side if the filter container dislodge the dust. Pre-filter not washable. Exhaust filter is a replaceable HEPA type.
The sound is powerful, yet quiet. The cat even tolerates the sound of the machine, so I presume that the ultrasonic whistling of other machines is not present in this one.
The Panasonic has a handle lock - hooray for handle locks!!! Nothing pisses me off more than trying to get the Dysons over thresholds between rooms, or avoiding rug fringes. Simply lower the handle and the nozzle pivots on the rear wheels, just like Ye Olde vacs of Yesteryear.
Manouvering is easy: 2 rear wheels and 2 decent sized rollers behind the brush nozzle soleplate. Auto height adjustment, so no carpet height control. Works even on the low profile kitchen carpet - I'm very impressed - The Vax Mach Air had to lose its front rollers to do the same task. The Panasonic is a heavy machine, so lifting it seems to be more a little more difficult than the Hoover Turbopower 3.
Tools are easy to use. The hose is stored in the style of the Electolux 600/Contour vacs. Scabbard long crevice tool stored inside extension tube. Crevice tool has two air holes, so the hose isn't tensioned to its contracted state. Additional extension tube supplied, plus a parquet floor brush. Hose handle on the MC-UL596 only, has an adjustable air-bleed hole to reduce suction.
Should the hose end become blocked, a safety suction release valve opens on the back of the machine, beside the data plate, allowing air directly into the motor chamber.
Dusting brush is the narrow type, as fitted to modern Panasonic uprights, but at least is usable (the Vax Mach Air multi-tool was not ergonomically designed).
Turbobrush has an extra litter-picker add-on strip for pet hair. Seems a little lacklustre, until I covered the four suction bleed holes on the neck shank, with my fingertips. Then it worked fine.
The plastic build quality is much better than some of the other machines. The flex is stored in the sensible style of the bagged Panasonics/Hoovers/Electroluxs: i.e. top hook and carrying handle. Flex is longer too, around 8 metres.
