Well proven engineering.
5/5
Simple mechanism, smiley face, cult following - what more could you want?
Did some deep cleaning of the abode, carpet and vinyl floor - everything was consumed.
Scooted over the laminate effortlessly.
Even gobbled up some loose plaster from the cupboard under the stairs (must get that sorted) .
Easily retractable cord, reasonably light for an average dude. Bit noisy - like a classic car.
Spares & bags etc easily available.
Cheaper options are available, but I haven't regretted opting for the classic.
