Pros & cons
Dreame H15 Pro Heat
- ✓Class-leading pickup — 22,000 Pa and hot water handle dried-on messes in one pass
- ✓Swing-out roller arm actually eliminates the baseboard edge strip
- ✓180° lie-flat design reaches under beds and sofas
- ✓TangleCut roller stays hair-free even with shedding pets
- ✓Hot self-clean plus heated drying — no sour-mop smell at the dock
- ✓3-year US warranty, longer than Tineco or Bissell offer
- ✓Quiet for the class at 63 dB
- ✗Heavy at 13.7 lbs — lifting it upstairs or over thresholds is a chore
- ✗Hot Water Mode drains the battery in about 20 minutes
- ✗The 72-minute runtime is quiet mode only; smart mode gives 40-60
- ✗The AI arm is oversold — think edge cleaner, not obstacle intelligence
- ✗$899 list price stings; only good value on the frequent ~$550 sales
Dyson V15s Detect Submarine
- ✓One machine handles both wet mopping and dry vacuuming without switching appliances
- ✓Separate clean/dirty water tanks keep you from mopping with dirty water
- ✓Laser dust detection shows exactly where debris is on hard floors
- ✓Swaps back to a standard fluffy or Motorbar head for carpets and stairs
- ✓60-minute max runtime is competitive for a wet-roller stick
- ✗Wet roller head requires a self-clean/dry cycle after every use
- ✗Dry dustbin capacity (0.76L) is on the small side for whole-home cleaning
- ✗Significantly more expensive than dedicated hard-floor washers
- ✗Heavier to maneuver than a standard V15 with the wet head attached
- ✗Replacement rollers and filters add to long-term cost
