Dyson V6. Works for a family of 6. To me, it looks like a toy. I scoffed when the DW unboxed the thing. However, it replaced the venerable Electrolux and Kirby at home and now goes on all of our RVing trips. It takes a few recharges to get through the whole house, but it can knock out the RVs in short order. Looks can be deceiving.
