Looking for a new cordless vacuum. Been using Dyson cordless for years, but always seem to last less than 4 years. Been looking at these for several months and now they are 25% off.
Based on the Miele suggested model; they recommend the Triflex.
I know cordless vacs will have their issues, but how reliable are these? Anyone compared to Dyson?
Thanks!
